What is LASIK?

LASIK is a type of refractive surgery used for correcting vision problems, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. LASIK is performed by ophthalmologists using a highly-precise laser. This operation helps to reduce patients’ dependency on contact lenses and glasses. LASIK eye surgery helps in reshaping the cornea in order to produce clear vision. Once the cornea gets reshaped, the eye’s focusing power gets improved. LASIK surgery also helps in enhancing patients’ visual acuity. Patients undergoing laser eye surgery also benefit from a short recovery period.

LASIK technology is improving at a rapid pace. A pre-LASIK examination is performed by the ophthalmologist who decides whether the patient is a good candidate for LASIK eye surgery. The LASIK procedure is quite simple but should be done carefully. Firstly, the corneal surface should be mapped with a computer controlled scanning device. This helps to determine the exact shape of cornea. The next step is to calculate the appropriate amount of tissue which needs to be removed. Doing so will minimize the need for corrective devices like glasses and contact lenses. The final step is ablation, which is carried out by a computer controlled laser. The patient should be aware before undergoing LASIK that the surgery is irreversible, although corrections can be made through further surgery. There is no question that LASIK has many benefits, but at the same time there are rare chances of complications like haziness, halo, corneal infection.

There are certain guidelines which a patient should be aware of before, during, and after LASIK surgery. Before LASIK surgery, if an individual wears contact lenses, then he or she should stop wearing them before their baseline evaluation. A baseline evaluation is done by an eye LASIK doctor to determine if individual is a good candidate for LASIK. One should stop wearing toric soft lenses at least 3 weeks before initial evaluation. Use of hard lenses should be stopped at least 4 weeks before. One should tell his or her doctor about their past and present medical and eye conditions. The doctor should also be informed about all the medications taken, including medications that the patient may be allergic to before the laser eye surgery takes place. The day before LASIK surgery, using creams, lotions, makeup, and perfumes should be stopped. LASIK surgery is a process that takes less than 30 minutes to complete. At the end of the procedure, a shield should be placed over the patient’s eye to protects it from accidentally being hit.

Once the LASIK eye surgery is done, ophthalmologists prescribe a course of antibiotic and anti-inflammatory eye drops to the patients. Patients are asked to see the doctor within the first 24 to 48 hours and at regular intervals after LASIK surgery for at least the first six months. Patients are also asked to rest and wear protective goggles to prevent rubbing of the eyes when asleep. In order to minimize the risk of complications, patients should abide by the guidelines and take precautions as suggested by their surgeons. It is very important to contact the ophthalmologist immediately if the patient develops any unusual symptoms at any point after LASIK surgery.
