A Comparison between 3.2mm and 5.5mm Incision Phacoemulsification, Intraocular Lens Insertion and Trabeculectomy with Mitomycin C(MMC)

ABSTRACT

We compared the results of phacoemulsification, intraocular lens(IOL) insertion, and trabeculectomy with mitomycin(MMC) in patients receiving either 3.2mm or 5.5mm incision. Our study revealed that the surgicalresults were comparable between the 3.2 and 5.5mm incision groups in terms of number of glaucoma medicatins, intraocular pressure(IOP) control, visual acuity except visual recovery in early period. The 3.2mm incision group showed stastically significant advantage in early visual recovery than the comparison group(P<0.05, Wilcox rank test). The incidence of anterior capsular opacity was significantly higher in 3.2mm incision group, requiring YAG capsulectomy for better vision than in 5.5mm group. This study suggests that both 3.2 and 5.5mm incision glaucoma triple procedures combined with Mitomycin C(MMC) may provide excellent postoperative IOP control and visual recovery without significant complication I intermediate follow-up period.
