  • Abstract
  • Look Inside

Two knives were designed to incise into and fracture the lens nucleus during phacoemulsification and aspiration surgery for cataract in 132 eyes. The knives were tentatively named as leaflet and microfeather knives. Following capsulectomy, the leaflet knife is inserted into the anterior chamber through a small corneoscleral incision to create a straight incision in the lens nucleus. After bisection of the nucleus, the knife is used to lamellarly incise the nucleus. Irrigating solution is then injected into fragments of the nucleus to further hydrodis-sect it. The ensuing phacoemulsification is thus facilitated by these procedures. The present method has the advantage that it protects the corneal endothelium from the damage of ultrasound and that it enhances the safety of phacoemulsification and aspiration procedure.
