Analysis the relationship between anterior chamber space and the corneal endothelial change in phacoemulsification

Objective To analyse the relationship between anterior chamber space and the corneal endothelial change in phacoemulsification.Methods Phacoemulsifi-cation and IOL implantation were performed in 60 eyes of 46 patients.The anterior chamber volume and chamber depth were measured by using Pentacam before surgery.Endothelial densities of the mid-cornea were measuredwith noncontact specular microscope before and one week aftersurgery.Results The mean preoperative anterior depth was(2.72±0.33 mm),the anterior chamber volume was(153.43±21.37)mm3,The corneal endothelial cell lossrate was 9.27%±5.17%.A significant negative correlation existed between the preoperative anterior chamber space and the postoperative corneal endothelial cell loss rate(P0.001).Conclusion Pentacam,as a new 3-dimensional mathematical model of the anterior segment,is helpful in evaluating the severity of endothelial damage after surgery and can be used to predict the outcome of the cornea.
