A Modified Iris Repair Technique and Capsular Tension Ring Insertion in a Patient with Coloboma with Cataracts



Purpose: We describe our successful experience using a capsular tension ring (CTR) and iris repair during cataract surgery in a patient with bilateral coloboma. Methods: A 67-year-old woman had no history of trauma, but had zonular deficiency and inferonasal iris defects in both eyes. An extracapsular cataract extraction and intraocular lens (IOL) scleral fixation was performed in the left eye. A CTR was implanted in the right eye through a sclerocorneal incision. After the IOL was placed centrally in the capsular bag, two paracenteses were made at the limbus (5 o’clock and 7 o’clock). A long, straight needle was passed through the 7 o’clock paracentesis site into a angled, blunt tipped 27 gauge needle inserted from the 5 o’clock paracentesis. The two needles were pulled out at 5 o’clock. After inserting the long needle into the blunt tipped needle at 7 o’clock, both were passed back through the 7 o’clock paracentesis site. The needles were pulled out again at the 5 o’clock paracentesis site tied. Equal tension was used to tie both sides. Results: Visual acuity improved to 20/20 in the right eye. Conclusions: Both capsular tension ring implantation and iris repair was successfully performed at the time of cataract surgery in a coloboma patient, which resulted in improvements in visual function and cosmesis
