Clinical analysis of phacoemulsification for eyes having received trabeculectomy / 中国基层医药

ABSTRACT

Objective To explore the clinical effects of phacoemulsification with intraocular lens implantation for cataract patients who have had glaucoma and have undergone trabeculectomy before.Methods Phacoemulsification with intraocular lens implantation was performed on 33 patients(38 eyes)with cataract after trabeculectomy.The postoperative visual acuity,intraocular pressure(IOP),filtering bleb,corneal endothelium and complications were observed.Results No posterior capsular rupture occurred and all the lenses were inserted into the capsular bags.Follow up for 3 months at least.The correct visual acuities were≥4.7 in 30 cases(78.9%),≥5.0 in 6 cases(15.8%).Postoperatively,the IOP of all eyes was below 20mmHg and there was no change in the filtering bleb.The loss rate of the corneal endothelial cells was 15.07%after the operation.The density of the postoperative corneal endothelial cells was statistically significant different from those of the preoperative(t=4.582,P＜0.01).The complications occurred more than that of regular phaeoemulsification.Conclusions Phacoemulsification is convenient and effective in patients with cataract after trabeculectomy.The incision should be made without damaging the filtering bleb.The surgery requires skillfully and actively enlarging the small pupils and protecting the corneal endothelium.
