The Ganesh-Grewal cystitome maker - A step in standardizing cataract surgery.

A well-centered, adequately sized continuous curvilinear capsulorhexis (CCC) is a prerequisite for successful cataract surgery. A perfect capsulorhexis ensures safe and effective performance of various steps of surgery as well as a correctly positioned intraocular lens (IOL) with optimal rotational stability. Ganesh and Grewal (GG) cystitome maker is a step toward standardizing the creation of a cystitome to reduce variations and complications associated with the crucial step of CCC in cataract surgery. We conducted a study to measure the repeatability and precision of cystitomes made by the GG cystitome maker versus those made manually with a needle holder. The results showed that the cystitomes made with GG cystitome maker had a lesser degree of variation. This indicates a more repeatable cystitome, which will inadvertently help in reducing the error caused by the instrument in making a good CCC during cataract surgery.
