Bottom Line: The aim of this study was to evaluate the impact of capsulorhexis diameter, localization and shape on posterior capsule opacification (PCO) development after cataract extraction with phacoemulsification.We retrospectively analyzed of 297 patients who underwent phacoemulsification and AcrySof SA60AT implantation.A small capsulorhexis diameter, its central localization and regular shape result in less PCO following phacoemulsification.

ABSTRACT

Background: The aim of this study was to evaluate the impact of capsulorhexis diameter, localization and shape on posterior capsule opacification (PCO) development after cataract extraction with phacoemulsification.

Material/methods: We retrospectively analyzed of 297 patients who underwent phacoemulsification and AcrySof SA60AT implantation. In a first group of 97 patients, 53 received small capsulorhexis (3.9 to 4.9 mm in diameter) and 44 patients received large capsulorhexis (5.0 to 5.9 mm in diameter). Another group of 99 patients was split into subgroups--66 patients whose capsulorhexis were centrally located and 33 patients whose capsulorhexis were paracentral. A third group of 101 patients was split into subgroups--a subgroup of 59 patients were classified as having a regularly rimmed capsulorhexis and a subgroup of 42 patients as having an irregularly rimmed capsulorhexis. At 6 months follow-up, PCO was classified as none, mild, moderate, or severe, depending on the number of quadrants involved.

Results: 86.79% of the patients with a small capsulorhexis had no or mild PCO (p<0.001), whereas, 68.18% of the patients with a large capsulorhexis experienced moderate or severe PCO; 89.4% of the patients with a central capsulorhexis had no or mild PCO (p<0.001), whereas, 75.75% of the patients with a paracentral capsulorhexis had moderate or severe PCO; 86.44% of the patients with a regularly rimmed anterior capsulorhexis had no or mild PCO (p<0.001); and 69.04% of the patients with an irregular capsulorhexis rim had moderate or severe PCO.

Conclusions: A small capsulorhexis diameter, its central localization and regular shape result in less PCO following phacoemulsification.

Mentions: The amount of PCO at 6 months was significantly different between the groups with small and large capsulorhexis (Figure 2) – 86.79% of the patients with a small capsulorhexis had no or mild posterior capsule opacification, whereas 68.18% of the patients with a large capsulorhexis had moderate or severe PCO. Patients with a small capsulorhexis had significantly less posterior capsular opacification than those with a large capsulorhexis (p<0.001) (Table 1).
