Abstract
AIM: To evaluate posterior capsular opacification (PCO) with hydrophobic acrylic intraocular lens (IOL, Sensar AR40e) and silicone IOLs after cataract surgery, to use a software program developed to provide an objective assessment of the amount of PCO in the digital images of the posterior capsule to quantify PCO. METHODS: Ninety-eight eyes underwent standardized phacoemulsification and "in the bag" IOL placement, were randomized to receive a three piece lens of hydrophobic acrylic or silicone, but lens materials were different in one case. In year 1 and 2, digitized retro-illumination images were taken from the posterior capsule. Images were analyzed by POCO software program, removing the Purkinje light reflexes, contrast enhancement, filtering to enhance low-density PCO. RESULTS: The percentage of PCO were 0.32±0.13 of hydrophobic acrylic IOLs in year 1, compared with 0.39±0.17 of silicone (P=0.37). In year 2, the percentage of PCO were 0.42±0.20 with hydrophobic acrylic IOLs and 0.34±0.18 with silicone IOLs (P=0.50). Of those patients with PCO in year 1 and 2, severity grades were 0.50±0.30 and 0.82±0.58 of hydrophobic acrylic cases, compared with 0.63±0.35 and 0.55±0.35 of patients with silicone IOLs (P=0.52,P=0.69) with no statistical significance.CONCLUSION: The POCO system is capable of producing an objective and repeatable measure of PCO that is relevant to assessing techniques of PCO prevention.关键词
