Corneal reshaping is designed to improve the optics of your eyes and correct structural irregularities causing your refractive errors. One common form you may have heard of is laser-assisted in situ keratomileusis, more popularly known as LASIK. It’s a surgical procedure that involves changing your corneal surface using an excimer laser, resulting in a more accurate light-bending process in your eyes.
While LASIK has been proven an effective myopia control option, its success rate largely depends on whether you meet its requirements. Here are four basic qualities a good LASIK candidate should have:
1. You Should Reach a Certain Age
Right now, the U.S. Department of Health and Human Services has not approved any type of laser for LASIK to be used for individuals under 18 years of age. This is why your eye doctor verified your age and birth date when evaluating you for this procedure. While there’s no upper-age limit for LASIK, changes to your eyes may occur once you reach your 40s and they may affect the surgery’s effectiveness.
2. You Must Have Healthy Eyes
Your eye doctor explains that certain eye conditions may affect how your eyes will respond to LASIK and heal afterward. If you have dry eye, eye infections or any eye injuries, we may treat them first before proceeding with the surgery. Cataracts and uncontrolled glaucoma are generally considered contraindications to this procedure as well.
3. Your Cornea Should Have Adequate Thickness
Since LASIK involves altering your cornea and the tissues underneath, it’s necessary that it has sufficient thickness. This requirement plays a major role in the surgery’s success. A thin cornea may compromise the results and even lead to bigger vision problems.
4. Your Visual Acuity Must Be Within a Certain Range
A lens prescription that’s too strong usually has less predictable LASIK results, which can be extremely risky. If you have extreme myopia, for example, your LASIK surgeon may need to remove too much corneal tissue, making you more likely to have vision complications post-operatively. Your optometrist may suggest an equally effective alternative for those with severe refractive errors.
