Laser vision correction surgery uses a delicate, FDA-approved excimer laser to improve vision by reshaping the cornea, or front surface, of the eye.
It's good for correcting nearsightedness, farsightedness and astigmatism (vision distortion caused by an irregular cornea). It's not for everyone, though. People who have cataracts or glaucoma, for example, shouldn't have laser vision correction surgery.
Our Laser VisionCare program covers three types of surgery:
LASIK (laser in situ keratomileusis): after a flap of cornea is cut and folded back, a computer-programmed excimer laser reshapes the cornea and the flap is replaced.
Custom LASIK: (or wavefront) uses FDA-approved, wavefront-guided technology to create a three-dimensional map of the eye. This guides the laser to reshape the cornea, enabling the surgeon to customize the surgery to the patient's individual needs.
PRK (photorefractive keratectomy): a laser is used to reshape the curve of the cornea after the surface layer is removed by gentle scraping.
