Abstract

A 38-year-old patient presented to us with complaints of blurred vision and photophobia in the left eye with an uncorrected visual acuity of 20/400, improving to 20/60 with pinhole. The patient underwent phakic iris-claw lens surgery 15 years ago for high myopia. On examination, there was anterior chamber rigid phakic iris-claw lens along with complicated cataract. We planned for sutureless self-sealing 6.5 mm sclerocorneal tunnel for explantation of rigid phakic iris-claw lens along with cataract extraction with irrigating vectis. There was postoperative reduction in astigmatism due to incision planned on steep axis, and visual acuity improved to 20/30 uncorrected. This technique provides significant advantages from the previously described techniques in terms of decreased postop astigmatism, no need for sutures, no issues of chamber instability and iris trauma and without the need for phacoemulsification.
