Abstract Details


To analyze the effects on corneal architecture and morphology of two different intra oculare lens (IOL) delivery systems (manual and authomated preloadead) in : i eye bank human corneas by Environmental Scanning Electron Microscopy (ESEM); ii patients after cataract surgery using Anterior Segment Optical Coherence Tomography(AS-OCT)


Eye clinic, Department of Surgery and Translational Medicine, University of Florence


Two different evaluations were performed: i endothelial profile was examined using ESEM in 20 2.2 mm incisions after IOL implantation on eye bank human corneas; ii wound architecture of 16 cataract incisions was analyzed using AS-OCT in patients after standard 2.2 mm phacoemulsification at post-operative day 1 and at 1 month. In both studies two different IOL injectors were used: manual (Monarch III group) and an automated preloaded system (AutonoME group). In each group high and intermediate IOL powers were implanted. The incision width was measured using corneal calipers in all corneas.


Descemet tears and more irregular incisions were observed by ESEM in eye bank corneas in high-power IOL manual group compared to automated delivery. The incidence of descemet’s membrane detachment, posterior wound retraction and posterior gape detected by OCT in patients was greater in the manual group at day 1, without significant difference between intermediate and high IOL powers


The automated controlled preloaded IOL injection system ensures the integrity and safety of the small-size corneal wound in intermediate and high-power IOL implantation
