Astigmatic changes after cataract surgery with 5.1 mm and 3.5 mm sutureless incisions.

We evaluated postoperative keratometric astigmatism in 80 eyes that had phacoemulsification and intraocular lens implantation through sutureless corneal incisions. The eyes were separated into two groups based on the use of rigid ovoid or foldable silicone lenses inserted through 5.1 mm corneal lip incisions or 3.

Displacement of bag-placed hydrogel lenses into the vitreous following neodymium: YAG laser capsulotomy.

We report two cases in which hydrogel lens implants have dislocated posteriorly into the vitreous body following YAG laser capsulotomy. These lenses were placed in the bag in conjunction with a capsulorhexis. A comparison with our results using silicone and poly(methyl methacrylate) implants indicates that this phenomenon has occurred only with hydrogel implants.

New spatula to facilitate bimanual phacoemulsification.

In recent years bimanual phacoemulsification has become an increasingly popular method of cataract extraction. We describe a new spatula designed to manipulate and protect the posterior capsule safely during phacoemulsification. In addition, this spatula can be used to facilitate irrigation/aspiration.

Clinical endothelial cell loss following phacoemulsification and silicone or polymethylmethacrylate lens implantation.

This study is a comparison of endothelial cell loss seen by two surgeons using the same surgical technique (posterior chamber phacoemulsification) with posterior chamber implants of two different materials (silicone and polymethylmethacrylate [PMMA]). One hundred four silicone lenses were implanted following phacoemulsification and compared with 160 PMMA lenses implanted during the same period. A significant feature of these procedures was the incidence of endothelial cell loss of greater than 1,200 cells/mm2.
