SO.09.11 Comparison of PCO development with different hydrophilic acrylic foldable IOLs with sharp optic edge Entz B. B., Pongrácz M., Szepessy Z., Salacz G.
Universitäts-Augenklinik, Semmelweis Universität Budapest Objective: During the study authors evaluated the PCO development of two different hydrophilic acrylic foldable IOLs from the same manufacturer with sharp optic edge design.
Methods: In 38 eyes the Meridian and in 48 cases the Akreos Adapt IOL were implanted and analysed. Therefore retroillumination photographs were taken. These were analysed with the image analysis program EPCO2000. The minimal follow-up time was 6 months after surgery. EPCO evaluation included total optic and central optic 3mm zone.
Results: PCO values for all IOL were mostly below 1,0 on a scale from 0 - 4. The mean EPCO-value measured on the entire optic was 0,30±0,21 by Meridian and 0,5±0,28 by Akreos Adapt IOL. The central 3 mm zone EPCO-values were slightly less. The mean central 3mm zone EPCO-value was 0,19±0,26 vs. 0,38±0,46.
Conclusions: The Meridian IOL showed considerably lower PCO formation. Both evaluated IOLs are hydrophilic acrylic with sharp optic edge design. The Meridian IOL has 360 degree sharp optic edge. The sharp edge of the Akreos Adapt IOL has some limitations. With four broad haptics presents this lens design a rather small real sharp edge rim of the optic. This difference plays according to our opinion a decisive role for the worse PCO-performance of the Akreos Adapt IOL. In the future should all modern IOLs have a real 360 degree sharp optic edge.
