Since shortly the F.D.A. approval of the Eximer laser in 1995, Dr. Evans has been performing laser eye surgery for the correction of nearsightedness, farsightedness, and astigmatism. The Excimer laser is used to reshape the cornea and refocus the light rays entering the eye on the retina. After having this treatment, most patients who normally require glasses or contact lenses to see distance objects are able to see clearly without such aides.

LASIK
LASIK is the most widely performed refractive laser eye surgery procedure. LASIK surgery is a 2-step procedure. First, Dr. Evans uses a specialized Femptosecond laser to create a thin clear flap of tissue in the center of the cornea. Then he is able to apply the Excimer laser to reshape your cornea and correct your prescription. Patients having LASIK typically have minimal discomfort and a quick recovery of their vision after their treatment. |

LASIK Procedure

|
For patients who have extremely complex prescriptions, Dr. Evans may suggest the use of a "wavefront guided" or "wavefront optimized" LASIK treatment. This is often called "Custom LASIK". Wavefront guided ablations can assist a greater percentage of patients in achieving 20/20 vision and avoid unwanted visual symptoms. We are happy to arrange screening examinations for LASIK during a routine ophthalmologic evaluation or at other times that might be convenient for you. Those with an interest in decreasing their dependency on glasses or contact lenses are encouraged to consider laser vision correction and call us at 781.928.2109 to schedule a free screening examination and consultation. |

PRK and LASEK
For some patients who are not good candidates for LASIK, several different laser eye surgery procedures are available to correct refractive errors such as nearsightedness, farsightedness and astigmatism. PRK, or Photo-Refractive Keratectomy was the first F.D.A approved type of laser vision correction. This technique reshapes the surface of the eye by flattening the surface contour of the eye rather than doing so under a "flap". Another procedure, LASEK is similar to PRK but preserves the first layer of the cornea in order to minimize discomfort. Both PRK and LASEK may be suggested in certain patients with very thin corneas where LASIK would not offer the best clinical results. |
