Purpose: In this study we evaluated the PCO development of three different hydrophilic acrylic foldable IOL´s with sharp optic edge design.
Method: 118 Medicontur hydrophilic acrylic IOL´s - in 66 cases the model HP600 and in 52 cases the model HP601 - and 70 Rayner Centerflex hydrophilic acrylic (model 570H) IOL´s were implanted and analysed. Therefore retroillumination photographs were taken. These were analysed with the image analysis program EPCO 2000 (Evaluation of Posterior Capsule Opacification). In all patients PCO expression was minimal 1 year after surgery examined. We analysed the posterior capsule opacification of the whole optic.
Results: PCO value for all IOL was below 1,0 on a scale from 0 -4. The distribution of PCO measured in the entire optic was 0,177±0,0983 by Medicontur IOL model HP600, 0,142±0,1027 model HP601 and 0,353±0,222 by Rayner Centerflex.
Conclusions: All three lenses show a low PCO formation and a low fibrotic reaction. If we compare PCO values of the entire optic, the Medicontur model HP601 seems most likely minimize PCO development.
