Evaluation of posterior capsule opacification after cataract surgery using Liquifaction Method

Abstract

Purpose Posterior capsule opacification (PCO) is still one of the most common complication following cataract surgery with IOL implantation. We evaluate the extent of PCO after cataract surgery ‐ torsional phacoemulsification and Liquifaction method removal of the epithelial cells (right eye) and torsional phacoemulsification (left eye). For PCO quantification we use two types of software. Methods In our prospective clinical study we examine patients 3, 6, 12 and 24 months after surgery, digital retroillumination photographs of the anterior segment, pachymetry, endothelial cell count (ECC) and best corrected visual acuity (BCVA) are obtained For evaluation of PCO we use EPCO 2000 software (Evaluation of Posterior Capsule Opacification) and OSCA software (Open‐Access Systematic Capsule Assessment). Results The BCVA two years postoperatively is 0.896 ± 0.13 (right eye), 0.883 ± 0.16 (left eye). Nd‐YAG laser capsulotomy one year after surgery underwent one patient (both eyes) and one patient two years postoperatively (right eye). EPCO results ‐ right eye: 0.260 ± 0.198 (3M); 0.259 ± 0.173 (6M); 0.308 ± 0.19 (12M); 0.419 ± 0.252 (24M), left eye: 0.279 ± 0.170 (3M); 0.280 ± 0.153 (6M); 0.333 ± 0.197 (12M); 0.480 ± 0.313 (24M) OSCA results ‐ right eye: 0.599 ± 0.240 (3M); 0.605 ± 0.333 (6M); 0.598 ± 0.256 (12M); 0.655 ± 0.402 (24M), left eye: 0.627 ± 0.403 (3M); 0.635 ± 0.360 (6M); 0.629 ± 0.328 (12M); 0.654 ± 0.452 (24M). Conclusion The Liquifaction method is save for occular tissue. One year after surgery most cases of PCO is graded as minimal. Supported in part by Charles University Grant Agency, No. 103809
