ABSTRACT

AIM:To compare the operation effect of 2. 2mm micro incision and 3. 0mm incision coaxial phacoemulsification. METHODS: Patients with age - related cataract ( 90 cases, 90 eyes) were enrolled in the study from January 2012 to June 2013 in our hospital, and they were randomly divided into 2 groups2. 2mm incision group (45 eyes of 45 cases), 3.0mm incision group (45 eyes of 45 cases). Corneal tunnel incision coaxial phacoemulsification was performed. At 1d, 1wk, 1, 3mo after operation, the visual acuity, corneal endothelial cell count, central corneal thickness, operation astigmatism were recorded. RESULTS:One day after operation, the visual acuity of 2. 2mm incision group were significantly improved, the difference was statistically significant ( P0. 05). Operation source astigmatism had statistically significant difference at 1d, 1wk, 1, 3mo after operation ( PCONCLUSION: The 2. 2mm small incision coaxial phacoemulsification with postoperative visual acuity improved more significantly, can significantly reduce the operation astigmatism.
