Endothelial Damage With Phacoemulsification and Intraocular Lens Implantation

Corneal Endothelial Toxicity of Air and SF6

“…It should be mentioned that the numerous reports on the beneficial effect of air injected into the anterior chamber to prevent its collapse during intracapsular or extracapsular cataract extraction [32][33][34][35][36][37][38][39] were of no help in the present study. In these older reports, the considerable mechanical protection offered by the short-term (few minutes only) filling of the anterior chamber with air would have masked any eventual sign of air endothelial toxicity.…”

Healon5 versus Viscoat during cataract surgery: intraocular pressure, laser flare and corneal changes

“…Therefore, cataract surgery became more and more atraumatic. In 1978 Irvine et al [12] demonstrated a postoperative cell loss of 18% after phacoemulsification and 26% after phacoemulsification followed by posterior chamber lens implantation. In the 1990s endothelial cell loss decreased with the use of small incision cataract surgery and advanced phacoemulsification techniques employing viscoelastic agents.…”

Comparison of central corneal edema and visual recovery between liquefaction and conventional phacoemulsification in soft cataracts

“…This is diagnostic system that scans the surface of the eye and acquires over 9000 data points in 1.5 seconds to map the entire corneal surface (11mm), analyzing the elevation and the curvature measurements on both the anterior and posterior surfaces of the cornea. Some trials have shown excellent correlation, 4 weeks afer surgery, between this system and ultrasonic measures and good repeatability (3)(4)(5)(6) . Data were analyzed using the Statistical Program Statistica, version 5.1.…”

“…Several studies have been performed comparing different surgical techniques and modes of modulating the physical parameters of the phacoemulsifier, with the objective of demonstrating the benefits of reducing conventional phacoemulsification-induced corneal edema, but very few studies have compared the technique of conventional phacoemulsification with liquefaction of the lens core by Aqualase ® (2,3,7,8,11,(15)(16)(17)(18)(19) . The purpose of this study is to assess central corneal edema and visual recovery after cataract surgery performed according to two approaches: conventional phacoemulsification and liquefaction by Aqualase ® .…”

“…S ince the 1970's, the importance of preserving the corneal endothelium has been established as a factor in the recovery from post-operatory edema (1)(2)(3) . Durovic et al has suggested that corneal edema is one of the main causes of low visual acuity in the immediate postoperative period after intraocular surger (4) .…”
