[A comparison study of various anterior capsulectomies]

The incidences of anterior capsular radial tears occurring in different capsulectomies performed on rabbit eyes under standardized conditions were compared. The eyes were randomly divided into 4 technique groups: (1) can opener, (2) capsulopuncture, (3) linear capsulotomy and (4) continuous circular capsulorhexis (CCC). The results demonstrated that the CCC technique has more advantages in comparison with other three groups. With the nuclear expression technique used in this study, no radial tears occurred with the CCC technique, whereas radial tears occurred in 100% of cases treated with other three techniques.
