Purpose: PCO development is still a frequent complication following cataract surgery. Different morphological PCO analysis systems have become available. This study compares the early PCO outcomes of different hydrophobic acrylic lens desgins using two analysis systems: EPCO (Evaluation of Posterior Capsule Opacification) and a computer based analysis (London System) of pixels.
Patients and Methods: Early postoperative PCO development of 32 eyes after cataract surgery was examined. One of 4 different hydrophobic IOLs (A, B, C, D) was implanted and 2-3 months postoperatively digital, retroilluminated images of the IOL were taken. These images with early PCO were analysed utilising EPCO and the London System. The scores of the individual evaluations were compared.
Results: Both systems rendered similar and comparable results. The early PCO values were slightly lower (A 0.31; B 0.04; C 0.31; D 0.06) when evaluated by EPCO compared to those of the London System ( A 0.46; B 0.13; C 0.57; D 0.14). Time requirements of the analysis were much shorter with EPCO (1.5 minutes) than with the London System (20-30 minutes).
Conclusions: With both systems similar PCO scores were evaluated in the early postoperative period. As early as 2-3 months postoperatively significant differences in PCO development could be ascertained.
