Refractive surgery can be used to treat myopia, hyperopia, astigmatism, and presbyopia. While LASIK and PRK are the most well known surgical treatment, other options for patients that may not be LASIK or PRK candidates include clear lens exchange (or refractive lens exchange) and ICL implants. Clear lens exchange involves removing the natural crystalline lens and replacing it with an artificial monofocal lens to improve distance vision or a multifocal lens to improve both distance and near vision. ICL implants are surgically implanted inside the eye in front of the natural crystalline lens. Some reasons that patients may not be LASIK or PRK candidates include prescriptions not FDA approved, dry eyes, thin corneas, and cataracts. Refractive surgery options can be discussed at your eye exam and, if appropriate, a referral can be given to the most appropriate surgeon in the Triangle.
