Laser eye surgery is an option for those with refractive errors who seek clear vision without corrective eyewear. Refractive surgery effectively corrects vision that has been limited due to conditions like myopia or astigmatism.
The precursor to laser eye surgery was a spring-mounted mallet used in the mid-1800s to flatten the cornea and “restore your eyesight and render spectacles useless.” Procedures have since evolved into a quick and efficient surgery that takes no longer than a half-hour.
Refractive errors occur when the cornea is misshapen so that light doesn’t refract properly onto the retina. Refractive surgery uses a precise laser to reshape the cornea to ensure the light lands directly on the retina to create a clear image.
Laser eye surgery has come a long way since its beginnings in the 1980s, with new advancements allowing for faster healing, fewer side effects, and less postoperative pain. The 2 most commonly performed procedures are LASIK and PRK, but several other refractive surgeries are also performed.
LASIK, or laser-assisted in situ keratomileusis, involves using a blade or laser to cut a flap in the cornea’s outer layer, called the epithelium. A computer-guided laser is then used to reshape the corneal tissue underneath, and the flap is replaced to act as a natural bandage.
LASIK involves minimal recovery time, typically a few days, with almost immediate vision improvement.
PRK, or photorefractive keratectomy, involves removing the outer layer of the cornea completely to reveal the corneal tissue underneath. A laser is then used to reshape the tissue beneath, and a contact lens bandage is placed overtop to promote healing.
PRK is generally more painful than LASIK, with week-long recovery time and vision improvement in around 2 weeks.
