AIM:To evaluate the efficacy of a method of small incision cataract extraction after glaucoma filtering surgery. METHODS:50 eyes of 50 patients with cataract after glaucoma surgery underwent manual small incision catarat extraction through a temporal scleral tunnel incision.The postoperative visual acuity,IOP, corneal curvature and filtering bleb were observed. RESULTS:Followed up for 3-12 months,the visual acuity of all the eyes were improved after surgery.There were no changes in IOP and filtering bleb.Postoperative changes in corneal curvature(0.75-1.25D) returned to preoperative levels 3 months after operation. CONCLUSION:The manual small incision cataract extraction through a temporal scleral tunnel incision is convenient and effective in treating cataract after glaucoma surgery.
