Background:
Rupture of the posterior capsule can occur as one of the complications during phacoemulsification.
Objective:
The aim of this study was to determine whether the risk of capsule rupture depends on the surgeon's concentration or experience, time of day and season, the side to be operated on and anatomy of the eye as well as the frequency with which it can be expected.
Material And Methods:
The patient collective was derived from patients who underwent cataract surgery by phacoemulsification between 2004 and 2014. All surgeries were performed by the same surgeon and constituted no primarily combined operations. Thereby, it was determined how many capsule ruptures occurred, with and without vitrectomy.
Results:
There were so significant differences between the left or right eye, weekday or month. During the various surgical steps of cataract surgery, the occurrence of capsule rupture was only significantly more frequent at the time of capsule polishing.
Conclusion:
Compared to the results of other studies, the risk of complications was lower in the operation collective investigated in this study.
