Abstract

We describe a new modified technique to release the peripheral iridocorneal adhesions that formed after Descemet stripping automated endothelial keratoplasty. The usual technique of goniosynechialysis was modified and performed using endoscopic fiber-optic light and camera probe to aid visualization of the adherent iris tissue and carry out uneventful 270 degrees release of adhesions. The iris tissue was gently pulled away using micro forceps. The modified technique was conceptualized, as the view from the cornea was very poor due to recent lamellar surgery and corneal oedema secondary to poorly controlled intraocular pressure. The blocked trabecular meshwork system was successfully recanalized, which allowed an adequate control of intraocular pressure. The graft survived the insult and cornea gained complete clarity giving the patient the desired vision and improved quality of life. How to cite this article: Rana M, Shah S, Pandey P, Masood I.
