حلقه داخل بافتي قرنيه

حلقه داخل بافتي قرنيه قطعاتي نيمه كروي پلاستيكي بوده كه براي درمان نزديك بيني و يا بيماري‌هاي ديگر در قرنيه كاشته مي‌شود. با قرار دادن اين حلقه شكل قرنيه تغيير نموده و با تنظيم توانايي تمركز، نور برروي شبكيه متمركز مي‌گردد. يك برش كوچك در لبه بالايي قرنيه ايجاد شده تا قسمتي از حلقه درون قرنيه قرار گيرد. سپس اين برش با بخيه‌هاي كوچكي بسته شده كه معمولاً چند هفته پس از جراحي خارج مي‌شوند.

Intrastromal Corneal Ring  Intrastromal corneal ring segments are semicircular pieces of plastic that are implanted within the cornea to treat mild forms of myopia. They also are sometimes used for other conditions affecting the cornea. The inserts are designed to change the shape of the cornea by adjusting the focusing power of the eyes so that light is focused onto the retina. A small incision is made near the upper edge of the cornea, in which the ring segments are inserted. The incision is closed with two small sutures that are usually removed two to four weeks after surgery.
