ABSTRACT
Purpose: To evaluate the endothelial changes after implantation of the Safety Flex Phakic 6 TM angle supported anterior chamber phakic IOL. Design: Noncomparative case series. Participants: 42 eyes [28 myopes and 14 hyperopes]. Methodology: Specular microscopy was done preoperatively and after implantation of the IOL at 1, 3, 6, 9 months and one year intervals. Main Outcome Measures: Significant endothelial cell loss [50% of the original count] is an indication for explantation. The central cell loss caused by the operation is approximately 3.6%; with time, this cell loss increases to 5.7% after one year. The peripheral cell loss caused by the operation is approximately 3.42%; with time, this cell loss increases to 3.9 1% after one year. The Safety Flex Phakic 6 TM was an effective and safe method for correcting myopia and hyperopia with safe and accepted endothelial cell loss after one year

Transvitreal pars plana sclerotomy using the contact Nd: YAG laser with a sapphire probe was performed on a group of rabbit eyes and compared with a similar procedure performed with a Ziegler knife. Although the intraocular pressure [IOP] was lowered in both groups of animals, the reduction was greater and more lasting in the group on which the Nd: YAG laser with sapphire probe was used. This technique may have application in cases with extensive peripheral anterior synechiae or where a vitrectomy as a combination procedure to clear ocular media is performed
