摘要

Microincisional handpiece for phacoemulsification was developed for prevention of incisional leakage which might jeopardize the maintenance of close system during operation and increase the possibility of intraoculoar complication. We report our experience of phacoemulsification cataract extraction with posterior chamber IOL implantation on 30 eyes with Microincisional handpiece and venturi pumping system via a 2.5mm incision. The other group of 30 eyes received the same procedure using standard handpiece and diaphragmatic pumping system via a 3.2mm incision. Significantly less intraoperative incisional fluid leakage (38.2±10.7ml vs 124.2±34.6ml) and less fluid volume in the collection bottle of phacoemulsifier (67.6±14.2ml vs 162.7±41.3m1) were noted in microincisional group. Surgery-induced corneal endothelial cell loss was also significantly less in microincisional group (4.75±0.61% vs 7.38±0.74%). Phacoem-ulsification time has no significant difference between these two groups. 1ntraoperativ observation of more stable anterior chamber, less turbulence flow and increased nucleus followability were noted with microincisional group. Our results suggest that microincisional system is helpful in reducing incisional leakage, decreasing corneal endothelial damage and providing more intraoperative control. This smaller incision also arouses the need for the development of smaller foldable intraocular lens.
