INTRA STROMAL CORNEAL RING SEGMENTS AS A NEW LINE FOR TREATMENT OF LOW MYOPIA
Magid Magdy Adly Ibrahim Fahim;
Abstract
Most current refractive procedures must overcome the effects of corneal remodeling and wound healing to produce the desired refractive. effect. The incisions of radial keratotomy (RK), for example, destabilize the structure of the cornea and can produce an,.,optical result characterized by diurnal variation. One of the new keratorefractlve techniques currently being researched is the intrastromal corneal ring segments (ICRS). It's composed of two
150° polymethylmethacrylate arcs and is inserted surgically into the cornea through a small 2-mm radial incision. Once inserted, both segments are positioned circumferentially in the peripheral corneal stroma outside of the central visual axis. Thickness, which appears to be the key variable, is used to obtain corneal curvature changes in accordance with the arc-shortening theory and the thickness versus dioptric correction
