AIM: To compare the effect and advantage of performing rhegmatogenous retina detachment surgery under operation microscope with under direct ophthalmoscopes.

METHODS: Ninety-three patients(93 eyes)were randomized to two groups, Group A(under operation microscope during rhegmatogenous retina detachment surgery, 47 cases), Group B(under direct ophthalmoscopes during rhegmatogenous retina detachment surgery, 46 cases). All patients were followed up for 2wk to observe success rate and visual improving rate.

RESULTS: Total percentage of success was 95.74% in group A and 80.43% in group B. The visual improving rate of group A was 82.98% and it was 67.39% in group B. Operative time in group A was significantly shorter than that in group B(P<0.05).

CONCLUSION: Performing rhegmatogenous retina detachment surgery under operation microscope is ascertaining and it is more effective and handy than performing that surgery under direct ophthalmoscopes.
