If you wear glasses or contacts and are tired of the hassle, LASIK eye surgery can be a life-changing option for clearer vision. LASIK works by reshaping your cornea so that light focuses properly on your retina, reducing or eliminating refractive errors like nearsightedness, farsightedness, and astigmatism. At Boston LASIK, patients from Boston and across New England—Brookline, Medford, Lawrence, Wellesley, Milford, Andover, and Burlington—trust an experienced team for advanced, personalized laser vision correction.
Step 1: Advanced Eye Mapping and Evaluation
Before LASIK, your surgeon performs a comprehensive eye exam to confirm you are a good candidate and to design your customized treatment plan. This includes detailed corneal mapping to measure corneal shape, thickness, and any irregularities, creating a “blueprint” for how the laser will reshape your eye.
During this visit, you can discuss your visual goals, ask questions, and review what to expect on surgery day and during recovery. Your surgeon will explain how LASIK compares with other options and whether a blade-free, all-laser approach is recommended for your eyes.
Step 2: Numbing the Eye and Getting Comfortable
On the day of your LASIK procedure, numbing eye drops are applied so you stay comfortable without the need for injections or general anesthesia. A small eyelid holder is gently placed to keep you from blinking, and a suction ring may be used to keep the eye steady while the flap is created.
Most patients describe feeling mild pressure rather than pain, and each eye typically takes only about 10–15 minutes to treat, with less than a minute of actual laser time. You may notice your vision dimming or going briefly dark during suction, which is normal and resolves quickly.
Step 3: Laser Flap Creation
Once your eye is numb and positioned, your surgeon creates a thin, hinged flap on the outer layer of your cornea. This can be done with a microkeratome blade, but modern LASIK commonly uses a femtosecond laser to create an ultra-precise, uniform flap at a preset depth.
You won’t see the flap being made; instead, you might feel gentle pressure for a few seconds. The flap is then lifted and folded back, like turning the page of a book, to expose the inner corneal tissue where the true vision correction occurs.
Imagine a three-layer diagram of the eye:
- Top layer labeled “Corneal flap” being gently lifted.
- Middle layer “Stromal tissue” where the excimer laser reshapes the cornea.
- Bottom layer “Retina” where light focuses sharply after reshaping.
Step 4: Corneal Reshaping With the Excimer Laser
With the flap lifted, a cool excimer laser reshapes the cornea by removing microscopic amounts of tissue based on your custom measurements. The laser changes the curvature of the cornea so light rays focus precisely on the retina, correcting nearsightedness, farsightedness, or astigmatism.
During this step, you may hear a soft clicking or humming sound and be asked to focus on a target light while the laser tracks tiny eye movements in real time. The reshaping itself usually takes less than a minute per eye, but this is where the science behind your clearer vision truly happens.
Step 5: Flap Repositioning and Immediate Healing
After the laser reshaping is complete, the surgeon gently places the corneal flap back into its original position. The flap adheres naturally within minutes without stitches, acting as a protective bandage that supports the healing process.
Your vision will likely be blurry right after surgery, but many patients notice improved clarity within the first 24 hours, with vision continuing to sharpen over the next days and weeks. You’ll receive protective shields, prescription eye drops, and detailed post-op instructions before returning home the same day.
What Does LASIK Feel Like for Patients?
Most people are surprised by how quick and comfortable LASIK feels. Thanks to numbing drops, you may feel only mild pressure during flap creation and possibly some temporary stinging or burning as the numbing wears off later that day.
Common experiences include watery eyes, light sensitivity, and a gritty sensation for a few hours, which typically improve quickly with rest and prescribed drops. Many patients can return to normal activities within a day or two, while still following activity restrictions and using eye protection as directed by their surgeon.
