In these pages you will find a description of the most commonly used refractive surgical techniques, advantages and disadvantages thereof, and what type of person might be a good candidate for these surgical solutions. This technique was refined by the Russian, S. Fyodorov, who performed countless surgeries, and helped to develop the world wide interest in his system. It is based upon changing the curvature of the cornea, with deep, but nonperforating incisions using a diamond scalpel. The adjacent figure shows a part of the scalpel, and in red, the area of incisions. The incisions cause the cornea to become flatter, thus correcting up to 7-8 diopters of myopia.
Surgery takes only a short period of time, and eye drops are used as the anesthetic.
The recovery period is rapid, for some patients, after a period of hours or days, the vision has improved and remains stable. The surgical technique stays out of the central optic zone of the cornea, or line of sight. Very little postoperative pain occurs. Can not correct well for myopia of more than 8 diopters. Fluctuating vision can occur, especially in the period immediately following surgery.
