Abstract

Aim: To retrospectively evaluate the effectiveness of the capsular vacuuming technique in reducing posterior capsule opacification (PCO).

Methods: Group 1 of the study consisted of 2752 eyes of 2752 patients with a cataract who had undergone phacoemulsification and IOL implantation surgery with anterior, equatorial, and posterior capsular polishing between January 2010 and December 2014. Group 2 consisted of 2761 eyes of 2761 patients with a cataract who had undergone phacoemulsification and IOL implantation surgery with anterior, equatorial, and posterior capsular polishing as well as posterior capsular vacuuming between January 2010 and December 2014.

Results: The mean patient age was 63.45 ± 12.23 years (range, 43-89) in Group 1 and 64.02 ± 13.36 years (range, 40-91) in Group 2. The two groups did not significantly differ with respect to age, sex, preoperative and postoperative uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and intraocular pressure (IOP) measurements (p > 0.05). At the 5-year follow-up, 253 eyes (9.19%) in Group 1 developed PCO requiring Nd:YAG laser capsulotomy, whereas 24 eyes (0.86%) in Group 2 developed PCO requiring Nd:YAG laser capsulotomy (p < 0.001). During capsular vacuuming, posterior capsule rupture was observed in the shape of a hole in only 2 eyes in Group 2. But the IOLs were implanted in the capsular bag in all eyes in both groups.

Conclusion: PCO is the most common complication of cataract surgery; therefore, surgical technique is important in preventing PCO formation. We recommend posterior capsular vacuuming together with anterior, equatorial, and posterior capsular polishing, as this method significantly reduced the PCO rate.
