Abstract

Objective To compare the outcomes of 1.8 mm coaxial microincision phacoemulsification-trabeculectomy with ultra-thin IOL implants compared to 3.0 mm small incision phacoemulsification-trabeculectomy with foldable IOL implantion. Methods In a prospective controlled study， 68 cases of glaucoma and cataract were selected at the Inner Mongolia Autonomous Region People′s Hospital between October 2011 and October 2013. All patients were randomly divided into two groups. In the small incision group， 34 patients underwent 3.0 mm coaxial microincision phacoemulsification-trabeculectomy with foldable IOL implantation； for the microincision group， 34 patients underwent 1.8 mm small incision phacoemulsification-trabeculectomy with ultra-thin IOL implantation. All cases were followed up at 1 week， 1 month and 3 months. Visual acuity， corneal endothelial cell density， surgically induced astigmatism， intraocular pressure， filtering bleb and complications were evaluated. A t-test， repeat measured ANOVA and Pearson′s chi-square test were used to determine statistical differences between the two samples. Results At 1 week postoperatively， visual acuity tended to be better in the microincision group and the difference was significant （χ2=7.114， P<0.05）. At 1 month and 3 months postoperatively， the difference in corrected visual acuity between the 2 groups was statistically significant （χ2=8.053， 10.532， P＜0.05）. At 1 week postoperatively， there was a significant difference in corneal endothelial cell density between the 2 groups （t=10.254， P＜0.05）. This was also true at 1 and 3 months （t=7.291， 9.334， P＜0.05）. At 1 week， 1 month and 3 months postoperatively， there was a significant difference in surgically induced astigmatism between the 2 groups （t=9.112， 10.732， 16.014， P<0.05）. IOP decreased after surgery （F=55.934， 69.063， P＜0.01） but there was no significant difference between the 2 groups. There was also no significant difference in blebs between the 2 groups （χ2=0.031， P>0.05）. No iris injury， posterior capsule rupture or anterior chamber bleeding was foun
