Abstract:
PURPOSE:To evaluate by Environmental Scanning Electron Microscopy (ESEM) the corneal incision architecture after intraocular lens (IOL) implantation in pig eyes, using manual, automated injectors or preloaded delivery systems. METHODS:Twenty-four pig eyes underwent IOL implantation in the anterior chamber using three different injectors: manual (Monarch III) (n = 8), automated (AutoSert) (n = 8), or a preloaded system (UltraSert) (n = 8). Acrysof IQ IOLs, 21 Dioptres (D) (n = 12) and 27D (n = 12), were implanted through 2.2 mm clear corneal incisions. Incision width was measured using corneal calipers. The endothelial side of the incision was analyzed with ESEM. RESULTS:In each group, the final size of the corneal wound after IOL implantation, measured by calipers, was 2.3-2.4 mm. The incision architecture resulted more irregular in the Monarch group compared with the other injectors. In every group the 27D IOL-implanted specimens showed more alterations than in 21D IOL-implanted samples, and this was less evident in the UltraSert group. The Descemet tear length was higher in the Monarch group than AutoSert and UltraSert group. CONCLUSIONS:The automated and preloaded delivery systems provided a good corneal incision architecture; after high-power IOL implantation the incisions were more regular and less damaged with the preloaded system than with the other devices.
