Samsung Medical Center (SMC) has introduced the latest innovation in Lasik surgery technology called the “Excimer Laser EX500” with Contoura Vision, the hospital said Thursday.

Lasik-- commonly referred to as laser eye surgery or laser vision correction-- is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. For most people, Lasik provides a long-lasting alternative to eyeglasses or contact lenses.

Contoura Vision won the approval of the U.S. Food and Drug Administration in 2013 and was selected as a next-generation refractive surgery by the American Cataract and Refractive Society in 2016.

The Excimer Laser EX500 with Contoura Vision corrects irregular corneal shapes and refractive errors at the same time.

The corneal topography maps the surface curvature of the cornea by lasering 22,000 dots on the outer structure of the patient's eye, and then the surface of the patient's rugged cornea is classified by height and smoothness.

Patients with an irregular corneal shape as well as refractive errors such as myopia and astigmatism can be corrected at the same time. Discomforts such as light blurring or night vision deterioration, which is considered to be typical side effects of vision correction, is lower than that of conventional correction.

According to the FDA, the rate of visual acuity of 1.0 or better after three months has been reported to be 92.6 percent. 98.4 percent of the patients said they were satisfied with the results.

“The corneal shape and refractive index differ from person to person, and Contura Vision is a state-of-the-art vision correction system that is tailored to individual corneal conditions,” said Professor Jung Tae-young_정태영 from the Department of Ophthalmology at SMC. “We expect it will improve the satisfaction of patients by reducing irregular astigmatism that is difficult to correct.”
