LASIK: What You Need to Know

People with very poor vision have different methods at their disposal to correct it such as wearing prescription glasses or contact lenses. However, there is a more effective way to correct poor vision and permanently eliminate the need for glasses or contacts altogether: the LASIK eye surgery. A long-standing procedure, the LASIK or “Laser-Assisted In Situ Keratomileusis” is a common surgical procedure performed to treat hyperopia or farsightedness, myopia or nearsightedness, and astigmatism.

The eye is covered by a transparent layer called the cornea, which is responsible for controlling the entry of light into the eye. As we age, the cornea starts to lose the ability to change shape. Thus, the LASIK eye surgery calls for the use of an excimer laser to reshape the cornea, allowing for the refocusing of the light entering the retina and improving one's vision in the process.

Prior to LASIK surgery, patients have to undergo a medical evaluation. A thorough exam will be administered to check the benefits or risks of the surgery. Information pertaining to the expectations and responsibilities of a candidate before and after the surgery will also be provided. If you are qualified for the surgery, it is highly recommended to give yourself plenty of time to review or to ask the necessary questions before signing a consent form.
