ABSTRACT
measured by OCT 1 and 3mo after surgery. Chi-square test was used to compare preoperative and postoperative BCVA. Pearsion’s correlation was used to evaluate relationship between postoperative BCVA and central foveal thickness.RESULTS:The ratio of BCVA<0. 05 was 30%,14%, 11%and 7% respectively for per-operation, 1wk, 1 and 3mo post - operation. After surgery, the central foveal thickness was significantly increased in group with BCVA<0. 3 comparing to group with BCVA≥0. 3. Three month post-operation, central foveal thickness was significantly decreased in both groups comparing to that in 1mo post-operation (P<0. 01). There has significant correlation between 3mo postoperative BCVA and central foveal thickness (r=-0.716, P<0.05).CONCLUSlON: ln this study, BCVA is improved after 3mo follow up. There has significant correlation between postoperative BCVA and central foveal thickness.
