For some individuals, refractive vision errors like farsightedness, nearsightedness and astigmatism are severe enough to warrant corrective surgery. Refractive surgical procedures, typically done by an ophthalmologist, change the curvature of the problem cornea in an effort to improve eyesight, maybe even get it back to where it was before the vision issue developed. However, not everyone is a good candidate for eye surgery. You will need an eye doctor to evaluate your eyes and health, then they may recommend surgery or offer alternative options.
There’s more than one surgical option to correct your vision, so if you’re considering pursuing this route, then the following information is for you! Here’s what an eye doctor in Lancaster, OH wants you to know.
Laser-assisted in-situ keratomileusis (LASIK)
The most popular refractive surgery is LASIK. For LASIK surgery, your ophthalmologist makes a thin, circular incision in your cornea. This creates a flap. Then the surgeon uses a heat-free laser (an excimer laser) to remove layers from the center of your cornea. This step either flattens its domed shape for nearsightedness, steepens the dome for farsightedness or smooths the dome for astigmatism. The corneal flap is then repositioned.
Good candidates for LASIK are those in good health, who are not pregnant and who have healthy eyes with a thick cornea. Additionally, pupils cannot be overly large, and you must have a corrective lens prescription within a certain range and stable vision for at least 12 months.
Laser-assisted subepithelial keratomileusis (LASEK)
LASEK is different from LASIK in that the eye surgeon does not cut a flap in the cornea itself. Instead, he or she makes it in the cornea’s thin protective cover (the epithelium). The same laser procedure is used in LASIK to either steepen or flatten the cornea. When complete, the epithelium flap is put back into its place. You will have to wear a bandage contact lens for a few days to heal.
Conductive keratoplasty (CK)
CK is a surgical procedure that can correct mild farsightedness and help folks over 40 years old who have a version of farsightedness called presbyopia. This option uses radio-frequency energy to apply heat to tiny spots around the cornea. The heat stretches the cornea, changing the degree of its curvature depending on the number and spacing of the spots. The change is not permanent.
Photorefractive keratectomy (PRK)
The first type of surgery to come on the scene to correct refractive errors was PRK. But even though PRK is still a common type of eye surgery, it is not as popular as LASIK. PRK has a longer healing time—the surgeon completely removes the epithelium, which grows back to conform to the cornea’s new shape.
Intraocular lens implant (IOL)
IOL implants are a good option for many people with moderate to severe nearsightedness. Phakic IOLs are clear lens implants that a surgeon places between the cornea and iris (or behind the iris) without removing your natural lens.
