To investigate the safety and efficacy of capsular tension ring ( CTR ) insertion combined with phacoemulsification and intraocular lens ( lOL ) implantation in patient with pseudoexfoliation syndrome after anti-glaucoma surgery.
●METHODS: A retrospective study was conducted of 10 eyes from 10 cataract patients with pseudoexfoliation syndrome following trabeculectomy surgery, and who underwent CTR insertion combined with phacoemulsification and lOL implantation between January, 2012 and June, 2013. All cases had nuclear cataracts ( nuclear hardness Ⅱ 1 eye, nuclear hardnessⅢ 4 eyes, nuclear hardness Ⅳ 5 eyes). One case with Ⅳ nuclear hardness cataract had iridodonesis and lens subluxation. Postoperative visual acuity, intra- and post-operative complications, anterior capsular opening, lOL position, and postoperative intraocular pressure ( lOP) were assessed. Follow-ups ranged from 3 to 14mo. The t test was used to analyze the variables studied.
●RESULTS: All patients had a successful CTR insertion combined with phacoemulsification and lOL implantation. A modified CTR insertion was performed in one case, the others underwent a standard CTR insertion. The best corrected visual acuity ( BCVA) was≥0. 5 in 3 eyes and 0. 3-<0. 5 in 2 eyes. However, BCVA was ≤0. 1 in 5 eyes. No decentration and dislocation of lOL was found during follow - up. Optic atrophy of different level could be found in all cases. The mean lOP was 16. 78±2. 48mmHg before surgery. And the average lOP is 16. 01±2. 33mmHg at 3mo postoperative (t= 1. 9955, P>0. 05). The most common intrao- and post-operative complications were corneal edema, small pupil, residual cortex, spontaneous zonular dialysis.
● CONCLUSlON: Suitable CTR insertion in appropriate occasion may be beneficial to patients with pseudoexfoliation syndrome after trabeculectomy during cataract surgery. lt prevents the lOL decentration and decrease the surgical complication. Less complication occurs at the early stage.
