Purpose: To compare the incidence of posterior capsule rupture and vitreous loss during phacoemulsification with and without the use of an anterior chamber maintainer (ACM) SETTING: Aristotle University Eye Clinic, Thessaloniki, Greece.
Methods: The surgical records of patients who had phacoemulsification by experienced surgeons over a 2-year period were reviewed. The cases were divided into 2 groups: surgery performed without the use of an ACM (no-ACM group) and surgery performed with the use of an ACM (ACM group).
Results: The no-ACM group comprised 231 cases and the ACM group, 312 cases. Posterior capsule rupture occurred in 19 cases (8.22%) and 22 cases (7.05%), respectively. Of the patients with posterior capsule rupture, 6 (31.57%) in the no-ACM group and 16 (72.72%) in the ACM group had vitreous loss and required an anterior vitrectomy; the difference between the 2 groups was statistically significant (P =.03).
Conclusions: The use of an ACM in phacoemulsification provided a consistently deep anterior chamber and approximately the same rate of complications as with a standard technique in the hands of experienced surgeons. However, when posterior capsule rupture occurred, the incidence of vitreous loss was significantly higher in eyes with an ACM.
