Comparion of urgical outcome of combined vicocanalotomy and cataract urgery with combined trabeculotomy and cataract urgery

PURPOE: To compare the outcome of combined vicocanalotomy, phacoemulification, and intraocular len (IOL) implantation with combined trabeculotomy, phacoemulification, and IOL implantation in patient with primary open-angle glaucoma (POAG). DEIGN: Nonrandomized clinical trial. METHOD: Fifty-even eye (57 POAG patient) that underwent vicocanalotomy, phacoemulification, and intraocular len (IOL) implantation between March 2000 and April 2001 and were followed for over 6 month potoperatively compried the vicocanalotomy (VC) group. Fifty-even of 105 eye (105 POAG patient) that underwent trabeculotomy, phacoemulification, and IOL implantation between April 1995 and February 2000 and were followed for over 6 month and < 2 year compried the trabeculotomy (LOT) group. The reduction of potoperative intraocular preure (IOP) and antiglaucoma medication ue in both group were compared. Bet-corrected viual acuity (VA) and complication rate were econdary outcome. The ucce probabilitie related to potoperative IOP level in both group were evaluated by Kaplan-Meier life-table analyi with log-rank tet. REULT: ignificant reduction of IOP and antiglaucoma medication ue occurred in both group up to 1 year potoperatively, but were not ignificantly different between the two group. The ucce probabilitie of the VC group for IOP control under 21, 17, and 15 mm Hg were 95%, 74%, and 44%, repectively, at 6 month, 95%, 67%, and 32% at 1 year, and not ignificantly different from the LOT group. All eye in the VC group had VA equal to or better than baeline 3 month potoperatively. The incidence of potoperative fibrin reaction (14 eye, 25%) and microperforation of the Decemet membrane (14 eye, 25%) in the VC group were higher than in the LOT group (P = .0004 and P < .0001, repectively). CONCLUION: Intraocular preure reduction and VA improvement after the two procedure were imilar in Japanee patient with POAG and cataract
