Objective
Three different intraocular lens (IOL) types were compared regarding posterior capsule opacification (PCO): CeeOn Edge 911A (Pharmacia), AcrySof MA60BM (Alcon), AMO Phacoflex SI40NB (Allergan).
Methods
In a randomized open multi-center study, 288 Patienten with bilateral senile cateact received in one eye the foldable IOL Pharmacia CeeOn 911 A (high-refractive silicone, sharp optic edge) and in the other eye either an Allergan SI40NB (high-refractive silicone, rounded optic edge) or an Alcon MA60BM (hydrophobic acrylate, sharp optic edge). 195 patients were available for examination after 2 years. In 44 pairs of eyes, the development of PCO was evaluated using the EPCO system.
Results
Compared with the Allergan SI40, in the eyes with a Pharmacia 911 the EPCO score was lower in 63% of cases, equal in 21% and higher in 16%. In comparison to the Alcon AcrySof, the score was lower in 44%, equal in 48% and higher in 8% of cases.
Conclusions
All examined IOL types showed a low incidence of PCO, with a tendency to less PCO in eyes that received an IOL with a sharp optic edge.
