[Precision pulse capsulotomy : The new capsulorhexis?]

The manual capsulorhexis created by Neuhann is still the standard procedure for opening the anterior capsule for cataract surgery. A limitation is the inaccuracy in the size and placement of the opening due to manual execution. In addition to the femtosecond laser a possible improvement in the standardization of capsulorhexis is provided by the Zepto procedure (precision pulse capsulotomy, PPC). In this case a 5.25 mm rhexis is created in a standardized fashion with a flexible suction adapter in which a nitinol ring is located. Whether the strength of PPC is comparable or better than that of the manual technique and how it behaves in terms of capsule shrinkage has not yet been finally clarified.
