What is LASIK Eye Surgery?
LASIK Eye Surgery is a refractive procedure that reshapes the cornea to correct nearsightedness, farsightedness and astigmatism. LASIK offers many improvements over other refractive surgery procedures. These include little or no post-operative discomfort, immediate vision improvement, and the ability to drive or return to work quickly-sometimes as soon as the next day. Most patients require no corrective eyewear after surgery although patients over 40 may require reading glasses.
Benefits of LASIK
Patients who undergo LASIK achieve clear vision without the need for glasses or contact lenses. LASIK offers many improvements over other refractive surgery procedures like:
- Little to no post-operative discomfort.
- Immediate vision improvement.
- Ability to drive or return to work quickly-sometimes as soon as the next day.
LASIK Eye Surgery Candidates
While LASIK surgery is very popular, it’s not right for everyone. There are certain criteria a potential patient must meet to be eligible for LASIK:
- Cornea thickness — LASIK improves vision by reshaping the front surface of the eye, the cornea. Your cornea needs to be thick enough to accommodate this reshaping.
- Prescription limits — LASIK results aren’t as predictable if the patient has a very high prescription, whether it be for nearsightedness, farsightedness, or astigmatism. Other vision correction surgeries may be better in these cases.
- Pupil size — Patients with overly large pupils can be at an increased risk for side effects such as halos, glare, and starbursts in low light.
- Age — Patients generally need to be at least 18, in some cases 21. This is mostly because vision continues to change in younger people.
- Stable vision for a year — This is related to the age issue. The patient’s vision needs to be at a stable prescription for at least a year prior to undergoing LASIK. The eyes need to settle in to their prescription.
- Pregnancy — LASIK is not available to women who are pregnant or nursing. This is because hormonal changes during these times can alter the shape of the cornea.
- Overall health — Certain degenerative conditions and autoimmune diseases can preclude a person from having LASIK. This is due to the body’s decreased healing ability.

Is LASIK safe?
LASIK is very safe if you are properly screened for adequate corneal thickness and corneal shape.
What happens before laser eye surgery?
Prior to any LASIK procedure, Dr. Keamy performs a thorough eye exam to make sure the patient’s eyes are healthy enough for the procedure. She checks the shape and thickness of the cornea, the pupil size, your refractive errors, and the overall health of your eyes. Since dry eye can be a risk with LASIK, she will check the moistness of your eyes and may recommend a precautionary treatment to lower your risk.
For specifics of the surgery, she will use a corneal topographer to measure the curvature and to create a map of your cornea. She will do a wavefront analysis, where light waves are sent through your eye to give a precise map of any aberrations affecting your vision.
If you wear contact lenses, Dr. Keamy will tell you when you will need to stop wearing them prior to your LASIK procedure. This is usually around two weeks prior to your procedure. The reason for this is that wearing contact lenses can alter the natural shape of your cornea.
LASIK Surgery Procedure
Before surgery begins, numbing eye drops are applied to your eye to prevent any discomfort during the procedure. The surgeon will then gently prop your eyelids open using an instrument called a lid speculum, a device used to stabilize the eye. It is normal to feel mild pressure. You will be asked to look at a target light for a short time while he or she watches your eye through a microscope as the laser sends pulses of light to your cornea.
Using targeted excimer laser beam energy, the LASIK procedure reshapes corneal tissue to correct refractive errors. This is done so that light rays are focused more precisely on the retina to produce clear, sharp vision.
Usually it only takes a few days to recover from LASIK eye surgery. Most people return to work 2 -3 days after surgery. Vision continues to improve for the next 1-3 months.
Laser Eye Surgery Results
After LASIK surgery, it usually takes several hours for things to become clearer. After the first 4 hours, each subsequent hour brings clearer vision. In fact, most patients are able to drive the next day.
LASIK Patient Testimonial
“Dr Keamy provided Lasik surgey for me over 5 years ago and it was the best decision I have ever done. She was excellent and the staff is so curtious and professional.”
Can LASIK be reversed?
Yes and no. If someone has a mild prescription and there is enough cornea, a second procedure can be performed. In some cases, the corneas are too thin and cannot be retreated.
Is LASIK permanent?
LASIK Eye Surgery is not permanent. As long as your myopia or hyperopia, your vision after LASIK should remain stable. However, as we age, cataracts or cloudy lenses develop. The cataracts will change the prescription and essentially undo the LASIK surgery. The cataracts can be removed to restore vision.
Complications such as vision loss are very rare with LASIK, but there are certain side effects that are somewhat common, including dry eye and temporary vision issues. Risks with LASIK:
- Dry eyes — LASIK surgery causes a temporary decrease in tear production. This can last for up to six months; eye drops can help manage this.
- Glare, halos, double vision — Your night vision could be affected after your surgery, with halos and glare showing around bright lights. Double vision can develop, as well. These usually last for a period from a few days to a few weeks.
- Under correction or overcorrection — If the laser removes too little or too much tissue, you may not have the correction you desire. This can be easily addressed with a second procedure for undercorrection.
- Astigmatism — If tissue removal is uneven, it can create astigmatism.
- Flap problems — The flap created to access the cornea can develop complications such as infection or unusual epithelium growth.
- Vision loss — In very rare cases, patients have experienced vision loss due to surgical complications.
