Hyperopic shift
WebResults: We found a higher hyperopic shift in patients belonging to larger capsulotomy group. In 3 groups the change in cylindrical error was found to be significant in the larger capsulotomy group. The change in BCVA pre & post procedure was also found to be significant among the 3 groups. Webnificant difference between groups. A higher hyperopic shift was shown in the steroid group and a more severe regression was reported in the NSAID group (p°0.001). Haze was significantly reduced in the steroid group (p‰0.005), espe-cially for myopic corrections over »5D(p‰0.015). Pain was significantly re-duced in the NSAID group (p ...
