Nd:YAG Laser Lysis of the Fibrinous Membrane and Remnant Substance on the Anterior Surface of Intraocular Lens

摘要

Purpose:To determine the effects of ND:YAGlaser to disrupt the fibrinous membrane and remnant substance on the anterior surface of intraocular lens.Methods:Nd:YAGlaser was applied on 23cases of fibrinous membrane forma-tion and 8cases of remnant substance on the anterior surface of intaocular lenses(IOL)which had not reponded well to steroid therapy,Eighteen cases were male and 13female.The mean age was49.7years(range,5-78years),The in-terval between IOL implantation and laser therapy was 0.5-30months in the fibrinous membrane cases and 3-10days in the remnant substance cases.The energy applied was0.8-3.0mJ/exp.with2-112exposures.mean follow-up period was3.6months.Results:Complications during therapy included only 2cases of slight iris bleed-ing,Visual acuity after therapy was improved 1line in 16cases,2lines in 11cas-es,3lines in 1case,4lines in 1case and 5lines in 2cases,No post-therapy com-plication was found.Conclusions:Nd:YAG laser lysis is an effective alternative to ramove the fibri-nous membrane and remnant substances on the anterior surface of IOL.Eye Sci-ence1995;11:128-130.
