摘　　要：·AIM:To evaluate the distance vision of Chinese patients with cataracts and corneal astigmatism after implantation of bilateral AcrySof toric intraocular lens (IOL) versus bilateral AcrySof spherical IOL.·METHODS:This study randomized 60 patients into equal groups to receive toric IOL or spherical IOL.IOL powers targeting emmetropia were selected for 93% of toric IOL patients and for 90% of spherical IOL patients.Assessments included monocular and binocular distance vision,with and without best correction.Patients also completed surveys about their distance vision.·RESULTS:Preoperatively,the two study groups were similar in age,in distance visual acuity,and in the magnitude of corneal astigmatism.At 6 months postoperative,binocular uncorrected distance vision was 0.06?à0.14 logMAR in the AcrySof toric IOL group,significantly better than the 0.14?à0.11 logMAR in the spherical IOL group (P<0.05).For eyes with emmetropia as a target,the equivalent of 20/20 uncorrected vision was more likely (P<0.001) in the toric IOL group (36% of eyes) than in the spherical IOL group (4% of eyes).No patients in the emmetropia/toric IOL group used distance glasses,as compared to 52% of patients in the emmetropia/spherical IOL group.All patients were satisfied or highly satisfied.Quality of distance vision was rated higher by toric IOL patients than by spherical IOL patients (P<0.05).·CONCLUSION:Bilateral AcrySof toric IOL is superior to bilateral spherical IOL in providing uncorrected distance vision to cataract patients with corneal astigmatism.·
