For beginner surgeons, it is difficult to recognize the posterior capsule during cataract surgery. In the case of brown cataracts with a thin posterior capsule and in cataracts with asteroid hyalosis, it is difficult to identify the capsule before intraocular lens (IOL) implantation even for expert surgeons. Here we illustrate five important signs, which can be practiced in routine cases to make sure the posterior capsule is intact, before IOL implantation.

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.
