Perfect anterior capsulorhexis using a dented cystitome

Abstract

We describe a novel intraoperative technique of measuring and creating an adequate size continuous curvilinear capsulorhexis (CCC) in phacoemulsification, using a dented cystitome as the ruler. A pair of curved tenotomy scissors is used to create a dent on the cystitome at a distance of 2.5 mm length (i.e., half of the desired approximate capsulorhexis diameter). The dented cystitome is used as a guide for making a CCC of approximately 5 mm diameter, which is considered adequate for phacoemulsification. This method of measuring the capsulorhexis helps in achieving a well centered and stable intraocular lens with a 360° overlap of the optic edge by the anterior capsular rim in the postoperative period. Using a dented cystitome for capsulorhexis mandates reliable and consistent results in the hands of the novice as well as the experienced surgeons.
