Dr. Anthony Roberts is an experienced ophthalmologist who specializes in refractive lens exchange (RLE) surgery. RLE involves replacing the natural lens in the eye with an artificial intraocular lens, similar to cataract surgery but to correct vision problems rather than treat cataracts. Depending on a patient's needs, RLE uses either a monofocal lens for single-distance vision, a multifocal lens for multiple fixed distances, or an accommodating lens for clear vision at all distances. RLE typically takes 15 minutes per eye to perform.
