In this prospective study, 80 patients were scheduled for cataract surgery in the second eye, who underwent cataract surgery in first eye 1-3 mo previously. The RE of each eye postoperatively was determined according to SRK/T formula. When the first-eye refractive error(FERE) exceeded ±0.5 D, the intraocular lens(IOL) power of the second eye was adjusted 50% of the FERE. The second-eye refractive error(SERE) was measured 1 mo after surgery. The FERE exceeded-0.50 D in 12 eyes(-0.675±0.16 D), and the adjusted SERE was-0.322±0.73 D(P<0.05). The FERE exceeded +0.50 D in 8 eyes(1.533±1.14 D),and the adjusted SERE was 0.168±1.36 D(P<0.05). The unadjusted SERE in 60 cases remained-0.38 to 0.42 D when the FERE within ±0.05 D. This prospective study confirmed that the prediction of the second eye could be improved by correcting 50% of FERE when this error exceeded ±0.50 D.展开更多
