Wearing glasses or contact lenses all the time can be really undesirable at times. If you are wishing to see without them LASIK eye surgery might be a good option. However, before getting one you will need to determine if you are a good candidate for this procedure. In this article, you can find accurate and helpful insights about LASIK eye surgery with the hope to help you form an informed decision and overcome your fears prior to your procedure. With fine-tuned surgical skills and time-tested technology available today, LASIK procedure is perhaps one of the safest eye treatments available. Also, we highly believe that its benefits far outweighs the potential risks.
LASIK Eye Surgery – An Overview
LASIK is an abbreviation of Laser in Situ Keratomileusis that simply means using an equipment (laser) underneath the patient's corneal flap in order to reshape the cornea (keratomileusis). The surgeon will typically folds back the flap then remove the corneal tissue using the excimer laser. Then the flap will be laid back in place to cover the area wherein the tissue was removed. While laser is often desirable by doctors because of its precision for the procedure, many patients are attracted to choose this type of treatment because of its significantly fewer complications compared to other eye treatments available.
LASIK eye surgery is performed in order to correct astigmatism, farsightedness and nearsightedness. For patients with nearsightedness condition, the main goal of the procedure is to flatten its too-steep cornea. For those woth farsightedness, a steeoer cornea should be achieved while smoothing an irregular into its normal shape is the aim for patients with astigmatism.
LASIK Eye Procedure – The Preparation
If you are one of those many people who are considering LASIK eye procedure, the first step should be choosing a good LASIK surgeon. Everything will start with proper medical evaluation whether LASIK is really right for you. The initial examination will include checking your past and present medical and your eye conditions. Your previous surgeries are also taken into account as well as the medicines you took which may have affected your vision or surgery. Also, it is very important to mention the medication allergies you have. Your eye structure and general prescription are carefully considered in order to help determine the best procedure that suits you.
Expect that the doctor will discuss the risks, benefits and alternative surgery for your eye condition. Also the doctor should explain the things you will need to expect before, during and after the LASIK eye surgery. During this time it is highly important that you should raise all the questions you wanted to ask to your surgeon. Ideally, the doctor should be very much willing to answer your questions with all honesty and even provide important handouts for you to review and further understand the process. Then you will be provided with a form, you will need to sign an informed consent form.
What is your surgeon Looking for during the Evaluation?
The eye doctor will look for the potential risk factors prior to the actual surgery. Commonly, patients with extremely high eyeglass prescription are not recommended for LASIK surgery since there would be a need to remove too much corneal tissue and it highly demands to be safely performed. Patients with very thin corneas could also be at high risk as it can excessively weaken after the surgery. For this case, other procedures such as surface ablation could be more appropriate. Patients who possess dry eye symptoms may not be ideal for LASIK surgery. Dry eye symptoms such as redness, tearing and burning, though there are many post care available, may be worsen after LASIK surgery.
During the surgery, it is expected the the surgeon will perform the procedure within 30 minutes for both eyes. The patient will typically be taken to a surgical suite and into the reclining chair or bed. The surgeon will then attach the laser system to a large machine and computer screen, the patient will be positioned underneath the laser where numbing eye drops are applied. After the surgery, patients will not be allowed to drive, arranging a transportation beforehand is therefore highly required. As soon as the process is finished, you will feel itch, burn and irritated however it is highly recommended not to rub your eyes under any circumstances. In order to ease these undesirable sensations, you could use copious artificial tears. Your doctor will also recommend you to buy and take a pain reliever in some instances when you feel increased discomfort. In most cases, you will need ibuprofen or other anti-inflammatory drugs.
LASIK is an outpatient procedure, you will not be asked to stay at the clinic overnight. Before leaving the clinic, you should ask your surgeon how long you should wait to start participating in activities such as jogging and walking. Typically, patients will need to rest for about three days following the procedure to start low impact activities again to avoid possible eye trauma. You will be asked to avoid exposing yourself to possible eye infection like going in hot tubs, pools and lakes during the healing process. Creams, makeup, lotions and any perfumes should not be used during these times as well as they can commonly cause buildup on your eyelids which can develop risk for infection.
Although most patients claimed that they are already having better visions after just very few days of their surgery, you may still experience hazy or blurry vision. Mild burning sensations may also occur from time to time, special eye drops which your doctor usually recommends will help ease the pain, keep your eyes moist and prevent infection. It is highly important to keep your eyes lubricated with prescribed drops and artificial tears to protect your vision.
A regular visit for the first six months from the day of your LASIK surgery is often required. This is when the doctor will closely examine your eyes and ensure that they are in good conditions. It's highly important that your eyes are assessed regularly and your LASIK surgeon will guide you to correct and maintain your vision.

The importance of one’s eyesight can never be undervalued. We always use our eyes from the time we wake up in the morning until we go to bed at night. Hence, good eyesight is not only an asset, but a necessity.
Unfortunately, there are many different factors that could lead to poor eyesight. Poor eye care, inadequate maintenance, diseases and aging are just to name a few. Not to mention natural degeneration. Try as we may, our vision gets poorer eventually.
Correcting Eye Conditions
When one suffers from vision problems, there are different methods he can choose from to correct this. The most common is the use of eyeglasses. This is particularly used by people who suffer from farsightedness, nearsightedness and astigmatism.
Its artificial lenses correct the eye condition through refracting or bending the light before it reaches the Retina. This aims to tweak the light’s focal point. However, people have become tired of having to wear eyeglasses every day.
Then, modern science introduced the use of contact lenses. This functions similar to the traditional eyeglasses except that it does not require frames since artificial lenses are directly applied to the eyes. However, this has its own downside, too. Abrasion and infection may arise if the lenses are not carefully applied.
A better approach that treats impaired vision will have to correct the actual Cornea for a long-term effect. This way, one does not have to rely on artificial lenses anymore. This process makes use of a computer-aided device to reshape the Cornea.
What is LASIK?
In a nutshell, LASIK is a refractive eye surgery that aims to reshape a patient’s cornea with the use of laser technology. This is an effective and highly successful method to correct myopia, hyperopia and astigmatism.
When the cornea is too steep, it leads to nearsightedness or myopia; if it is extremely flat, it causes farsightedness or hyperopia. If the cornea is shaped like a football, astigmatism occurs.
To reshape the cornea, the surgeon cuts a flap of tissue from the Corneal Epithelium. This is done to gain better access to the actual tissue behind it. At the same time, the flap serves as a protective covering after the procedure.
Risk Factors and Limitations
Like any other procedures, not everyone is suited for LASIK eye surgery. Initial tests, diagnosis and preparations are essential to determine if one is a suitable candidate. There are particular anatomical factors and conditions that must be considered as well since certain conditions can increase the risks of complications.
For starters, patients with dry eyes are not advised to undergo this procedure. This is due to the laser’s inherent ability to reduce moisture in the eyes.
This is also not recommended to candidates with corneas that are irregular or too thin because these conditions increase the chances of refractive error that could result in over-correction or under-correction.
Pregnant women may not be subjected to lasers, so they are not good candidates for this process either.
Age is one other major factor to consider. Patients aging 18 years old and above are the most ideal candidates. Although the surgery can be done on younger patients, it requires permission from the parents or guardians.
LASIK procedure is generally safe with success rates continuously increasing as technology evolves. Instances of under- and over-correction are also minimized as the surgeon gains more experience. Still, possible complications cannot be completely overruled.
It is normal for patients to feel slight discomfort following an operation. Light sensitivity and mild irritation are to be expected while the eyes heal itself. Glare, halos, reduced sharpness, hazy visions and other disturbances may also be experienced by the patients in the first few weeks to up to six months.
Some cases of epithelial in-growth have also been reported in less than 2 percent of the LASIK procedures. This occurs when cells of the epithelium or the cornea’s outer cells grow underneath the flap. Luckily, this anomaly is self-limiting and poses no serious threat.
Other procedures have resulted to irregular astigmatism. This happens when the corneal surface becomes uneven after the procedure. This condition may require re-treatment or an enhancement surgery to be corrected.
Only rare instances of eye infection have been noted, too. This is due to the sterile nature of the flap- the tissue that has been lifted and repositioned to serve as a natural bandage. Surface ablation procedures like the PRK have higher percentage of eye infections.
How to Reduce the Risks
No surgical procedure is absolutely safe and complications may arise. Fortunately, there is a way to mitigate the risks and increase the success rate at the same time. If you are thinking about undergoing LASIK surgery, here are some of the most important things to remember:
1. Look for a qualified doctor. A successful outcome is largely dependent on the practitioner as it is on the process. Look for an efficient ophthalmologist to properly diagnose your condition. They are most fitted to provide you with the best methods to undertake. If a surgery is positively necessary, choose a surgeon who uses sophisticated technology with good surgical skills.
2. There are no shortcuts. There are some preparations to be done before the actual surgery. Make sure that you comply with all the required diagnostics tests. Conversely, you have to dutifully follow the doctor’s prescription on post-surgical care to speed up the recovery process and avoid complications.
3. Visit your doctor regularly. Just because your vision problem has been corrected does not mean you can care less of your eyes. Make it a habit to visit an eye doctor for proper maintenance.
Vision is highly important in everything we do. To lose it is very critical. Luckily, the success of LASIK surgery has been overwhelmingly positive. Around 96 percent of patients achieved their desired vision after a successful operation.
Furthermore, the procedure is painless and does not require bondages or stitches. Most importantly, it is perfectly safe to redo the process if age and natural degeneration cause your vision to eventually deteriorate.
As long as you take the time to do thorough research, systematic preparations and diligent post-surgery care, then you can rest assured the procedure will turn out successful.

The sight is regarded as one of the most important of our senses and so are the eyes through which we see. Through the sense of sight, we go through our everyday routines with unparalleled ease. We are heavily dependent on sight most of the time and even as we interact.
Whenever we communicate to everybody around us, eye-to-eye contact is almost a must. From relaying the message to understanding emotions and even to observe reactions, we rely on what we see.
Entertainment has also been developed to better please the sight. The better we see things, the more we enjoy them. That is why the development of HD monitors and screen was welcomed by consumers of electronics. Modern gaming is even witnessing the introduction of the use of wearable eye gadgets for an improved gaming experience.
Important as it is, the eye needs to be protected and be well-cared. The organ is well-positioned for better perception and protection. Like most organs in the head, the eye ball is protected by the skull against hard objects. The frontal part of the human eye is also protected by the eyelid to prevent injury. Other glands also provides nourishment to eye tissues.
Despite the anatomic protection and proper care of the eyes, diseases and disorder may still affect the eyes and therefore the vision. Hence, it is important to cure and correct these conditions.
How We See
For us to see, the light that gets into the eyes through the hole in the eyes called 'Pupil' needs to be focused right at the tissue called the 'Retina' which is responsible for sending the message to the brain. To do this, our eyes have 2 lenses working with each other. The first one is called 'Cornea' which is located outside of the Pupil. The second one located behind the Pupil is simply called the Lens.
Any problem with the Cornea could affect the vision resulting in unwanted eye conditions. Common conditions are near-sightedness or myopia, farsightedness or hyperopia and astigmatism wherein images appear distorted or blurry whether near or far. These conditions are mainly due to light not focused on the Retina. If the light or image is focused before it reaches the retina when looking at a distant object, it results in myopia. When a nearby object appears to be blurry because image or light doesn't come into focus before the retina is reached, then you get hyperopia. As for astigmatism, deformation or uneven surface of the cornea usually resulting to the image being focused twice causes all images to be distorted.
For the longest time, eyeglasses have been used to correct impaired vision. The device works by refracting or aligning the light so that the focus reaches the Retina. Through time, contact lenses were also developed so that they can be placed directly on the eye without the need for frames.
In the late 80's and early 90's, a newer approach is developed to address these eye conditions without the need for wearable devices and with permanent result. This method is the LASIK eye surgery.
The procedure primarily involves reshaping the Cornea to ensure that the focal point of the image reaches the Retina without having to rely on artificial lenses like eyeglasses and contact lenses. This is a one-time procedure done by ophthalmologists.
The entire procedure uses a machine run by computer system to ensure precision. The process starts by applying alcohol directly on the Epithelium so that the cells would weaken. Then, LASIK surgery equipment creates a flap of the Epithelium or the outermost layer covering the Cornea. The flap is then folded away from the laser field so that it doesn't get in the way of the operation.
Once the outer layer is removed, the laser could now reshape the Cornea by applying laser in a finely controlled manner so that the tissues, which are usually tens of micrometers thick, evaporates. This procedure is much like shaping lenses to achieve the desire refraction of light and therefore ensuring that the focal point is right on the Retina. The process involves flattening the surface of the Cornea, to treat myopia, or making the surface much rounder for the treatment of hyperopia. As for astigmatism, the treatment works on making the surface of the Cornea much more even.
The process has both advantages and disadvantages as with other surgical procedures. But overall, the procedure has excellent success rates.
Like any photorefractive or laser surgeries, the procedure only needs to be done once and the result lasts, which means there is no need to use your eyeglasses or contact lenses anymore and no maintenance needed.
Computer-aided machines do the job which means fine precision.
Compared to other laser eye surgeries, LASIK has been proven to cause lesser quicker recovery and inflammation. It also causes lesser irritation and discomfort after the operation.
Better quality of life
After a successful operation, patients could expect to live a better life with better vision. When you can see things clearly immediately after opening your eyes without the need of eyeglasses or contact lenses, it surely means life is now hassle-free.
The eye might experience dryness after the procedure and therefore a bit of discomfort but are usually temporary. The patients are therefore usually prescribed anti-inflammatory eye-drops to address this.
Possible risks of the procedures may include loss of vision due to infection. Some patients have also reported cases of either under or over-corrected conditions. Any irregularity with the position and healing of the flap may also cause discomfort and may affect visual acuity though oftentimes could be corrected.
Most of the risks mentioned could be avoided by doing proper consultation and strictly following preoperative procedures to ensure that the eye is at its best condition. It is also necessary to follow the guidelines and care after the surgery to ensure that the eye recovers well and to avoid infection. Furthermore, patients need to find the best possible clinic offering the surgery since a more advanced equipment and a well-experienced ophthalmologists guarantees better chances of successful operation.

We have heard it many times, “Eyes are the windows to our soul”. There are many people who believe this phrase to be true. People's eyes are like the gateway to some door, we give and take vibes and they always speak the truth. If you are to open your eyes and make an eye contact to the other person when communicating, you will see that some people have real truth, there are others that are afraid, while some are intimidated. Also, it is in the eyes where we can see the innocence and truest interests of the people. Our eyes define who we truly are from the inside. It shows the reality of ourselves, unfortunately for us, many haven't genuinely realize and appreciate their importance.
Out of all our senses, human body uses this sense of sight the most. Vision is an occurring process which includes continuous interaction between the human's nervous system, bran and the eyes. When we look at an object, what we really see is light which the object reflects. Technically speaking, our eyes are well protected since they lie within the bony sockets of our skulls. Meanwhile the eyelids are responsible for protecting the eyes in front. It is a natural defense activity for the eyes to blink at the average of once every six seconds, washing the eyes with salty secretion. However, these protections are never enough to keep them protected at all times and maintain a healthy vision. When we take them for granted we commonly develop eye problems and diseases.
Common eye conditions and problems by people include myopia in which only nearby objects are distinct. This is also referred to nearsightedness. On contrary, the ability to only distinct far away objects is called farsightedness or hyperopia. Astigmatism is another common problem which is define as a condition when images appear to be blurred regardless if they are near or far. People ages 50 years old often develop eye condition called Aging Eye or presbyopia. In case you are one of those sufferers of any eye conditions mentioned, perhaps you have already been hearing about surgical procedure – LASIK to reduce our dependency on contact lenses and glasses and improve vision. LASIK stands for Laser-Assisted In Situ Keratomileusis that permanently changes the shape of the eye's clear covering – cornea.
How do you know what's best for your eye condition? In this article you will find an in-depth look into the benefits and some disadvantages of LASIK eye surgery which will surely help you make a more informed choice.
The Advantages of LASIK Surgery
1. LASIK is Highly Precise Results to Fewer significant complications
The technique uses excimer laser, it usually starts with the thin flap's creation. With different techniques available today, LASIK is considered more desirable from the rest because of the procedure's precision and fewer significant complications.
2. LASIK has Long-Lasting Results.
The stabilization period usually takes 3 months where the eyes adjust, following this period LASIK result is permanent. Patients would not need to undergo any follow-up procedures unless advice by surgeons due to normal loss of eyesight cause by illness and aging. With modern techniques, it is very much possible that this procedure can last a lifetime.
3. Fast Results and fast recovery.
In general, laser treatment through LASIK procedure takes less than one minute per eye. Perhaps, the patient will need to stay for about 60 – 90 minutes in doctr's office after the surgery but you are expected to be comfortable during the procedure. Most patients can see improvements of their natural vision immediately after the process. The next day, patients can see well enough.
4. No more glasses, no more contacts.
The technique is designed to improve vision thus there's no need to go out and purchase expensive prescription glasses and contact lenses. Take them off and go for your new look and style that you ever wanted.
5. Develop Higher Self-Esteem, Improves Social Life
After the surgery, wearing glasses and contact lenses will not be in your daily routine anymore. There have been many patients who claimed that they now feel more confident with their selves and have better career opportunities. There are some who even decided to take up new hobbies and engage in sports which they once felt restricted to do when wearing glasses and lenses. As they become confident with themselves, they have learned to do more activities and relate to more and more people improving their social lives.
The Potential Risks Associated with LASIK Surgery
1. Dry Eye Syndrome
Following the surgery, the eyes may not be able to produce enough tears to make it comfortable and moist. Intensive drop therapy may be needed to reduce the discomfort.
2. Not Reversible
We have to understand that the procedure is done in the most sensitive part of our eyes. Therefore this procedure is not reversible.
3. Decrease in Sharpness and Contrast Sensitivity
Clients may experience difficulty in situations of low contrast, example at night. Even with good vision during the vision test, objects may have the tendency to appear fuzzy.
LASIK surgery has been an affective procedures wherein most people are satisfied with their visions after undergoing the procedures. However, just like everything, getting a surgery does come with some risks. The risks associated are typically explained thoroughly by surgeons before the procedures, this should be the “informed consent” process.
The key to improve your sight and maintaining good vision always come with proper self preparation for the LASIK eye surgery. It is highly advise the you will meet an adviser who can discuss all the important details during and after the surgery. At your meeting during the surgeon, your eye conditions will be carefully checked, evaluated and tested. It is also very important that your medical history will be reviewed by your surgeon prior to performing the surgery. Most importantly, you should ask further questions which you may have. Afterwards, you could book and appointment for your procedure.
Remember our eyes are essential organs of our body. We should never take them for granted!

Choosing to undergo a LASIK eye surgery can be one of the best investments you could ever make in yourself. Not only will it help restore your eye sight to its optimal levels but you will have the great peace of mind that you no longer will need to deal with contacts, fuzzy vision or glasses until the unforeseen future. This can give you a boost in confidence in addition to allow you to finally be able to experience good eyesight again, which can do wonders for you and other senses you have.
More than likely you have a plethora of different feelings and emotions going through your body preparing for your LASIK surgery. This can include excitement, anxiety, anxiousness and nervousness, to just name a few common emotions. These emotions cannot only last the entirety of the preparation but they can encourage the way the surgery and recovery outcome as well. So making sure that you stay calm and your emotions are controllable is a very important part of the preparation process.
There are several others ways to prepare for your LASIK eye surgery. Some things you may have already thought of and other ways you may have overlooked previously. It is very common to feel overwhelmed before surgery and have a lack of focus. But taking a look at the different ways we suggest for you to prepare for your LASIK surgery can easily change this.
Here are several ways how to prepare for LASIK eye surgery:
Stop wearing contact lenses – If you have prescribed contact lenses and wear them on a daily basis or occasionally it is time to stop wearing them and switch to your glasses full time. Typically a good time to switch to glasses is between two to four weeks before the procedure. The reason you need to stop wearing them is because contact lenses can change the shape of your cornea. If your cornea becomes distorted due to the contact lenses it may lead to inaccurate measurements. No matter your specific situation, your doctor will give you guidelines about glasses and contact lenses prior to the procedure.
Another reason to stop wearing contact lenses is so you can begin to get use to not having any contacts or glasses. If you highly rely on your contacts, it may be a shocker after the procedures to have your eyes free once again. Many people become very comfortable with their contacts lenses in and feel uncomfortable when they are not in. Taking them off will allow you to begin to get used to it and have it become a regular and comfortable feeling again.
Stop wearing eye make-up – All eye make-ups including creams, perfumes, lotions or powders should not be used 2-3 days prior to your surgery. This will help prevent any debris going into the eyes from your eyelashes or lids, which can minimize infection and help recovery time. More than likely your doctor will instruct you to clean your eyelashes and lids daily prior to your procedure. Eye make-up is also known to make eyelids and eyeballs become swollen and puffy which can distort the actual size of your cornea. This can be a problem when it comes to making measurements for the procedure and can have a poor surgical outcome.
Arrange a ride home after surgery - Immediately after the surgery you may still feel the effects of the medicine that was given to you before your surgery. Some common side effects include grogginess and dizziness, which is not a state that you should be in while driving. Many patients’ also may have blurred vision after surgery. Both the medication and the blurred vision will not allow you to drive obviously but another reason why you would want a driver is so you have someone to look after you during the first part of your recovery. You may need assistance with different tasks once you get home and may need a hand to get to and from the car.
Understand the cost of LASIK surgery – This procedure is commonly considered an elective surgery, meaning that most insurance companies will not cover the cost of the surgery since having the surgery is a choice and not a necessity. Budgeting adequate amount of money to pay for the expenses out of pocket will need to be addressed. Although it is always nice to pay cash for such a large expenses, more than likely your surgery center offers some type of financing that you may apply for. There are also many banks that offer financing for procedures such as LASIK and are often easy to be approved.
Avoid antihistamines or other drugs than can cause dryness of the eyes – Many times individuals use an antihistamine on a daily basis for allergy problems. Using them the day of your procedure may make your eyes dry out and can cause a problem during the surgery. Make sure if you do regularly take antihistamines that you consult with your doctor about alternatives or if it will be ok for you to still take it. Other than drugs that dry eyes out their typically are not any other restrictions for eating, drinking or medications the day of the procedure.
Wear comfortable clothes - Although the surgery is fairly quick and only lasts about 10 minutes per eye, you may still be at the surgery center up to two hours. Make sure to wear relaxing clothes so you are not uncomfortable during and after the procedure at the surgery center. In addition to comfortable clothes, make sure not to where anything such as things in your hair that may interfere with the position of your head during surgery.
Eat a light meal before – Although it is a quick procedure it is important that you have something in your stomach. Sometimes people may feel queasy or uneasy after taking the medication and having food in your stomach may help from not experiences worse side effects. Also being in a doctor’s office for a couple hours you may begin to feel hungry, so make sure to eat before so you can hold off until your next meal.
Don’t forget to take time off – Most people it takes a few days for their eyes to heal and be able to be back to normal (or even better with your new eye sight!) so make sure to take that adequate time you need. Depending on your circumstances and specific situation, your doctor will write you a doctor’s order and can consult with your job to make sure that you can heal properly.
Relaxing is the most important thing that you can do to prepare for your procedure. It is normal to feel anxiety and become anxious before your surgery. Ask your doctor any questions you may have and they will make sure that you are comfortable for the procedure. Having LASIK surgery is one of the most exciting surgeries that we as humans can undergo because it can enhance one of our most important senses. Preparation is key in order to have a successful procedure, so make sure to take all of our tips into consideration and get ready for a wonderful new you.
