誗 AIM: To assess the clinical outcomes and safety of toric intraocular lenses (Toric IOL) for the correction of preexisting corneal astigmatism in cataract patients having micro-incision phacoemulsification. 誗METHODS: Fifty-eight patients (69 eyes) with age-related cataract and corneal astigmatism were included in this clinical case series study and had micro-incision phacoemulsification combined with of Acrysof Toric IOL implantation. Preoperative corneal astigmatism was more than 0. 75

Uncorrected visual acuity (UCVA) , best corrected visual acuity (BCVA) , postoperative residual astigmatism and toric lens axis were observed. The postoperative data was collected on the day 1, month 1, 3 and year 1 after operation. 誗RESULTS: At 1 year following surgery, the UCVA rise up to 0. 70依0. 11 from 0. 15 依 0. 06 (字 2 = 86. 67, P< 0. 05) on average, and BCVA from 0. 21 依 0. 01 to 0. 73 依 0. 20 (字 2 = 82郾 23, P< 0. 05) indicating a statistical difference. Mean preoperative figure of corneal astigmatism and anticipated residual astigmatism was 2. 25 依 0. 73D and 0郾 34依 0. 09D, and corneal astigmatism was 0. 51 依 0. 21D one year after operation, indicating a statistical difference between preoperative and postoperative astigmatism (t = 12. 48, P<0. 05). There was no statistical difference among postoperative corneal astigmatism and anticipated residual astigmatism (t = 1. 69, P> 0. 05). The D-value of IOL positioning and predict axis was 3. 79毅 依 1郾 21毅 one year postoperatively. Ninety-six percent of patients had less than 5. 00毅 of rotation, and no operative complication was found. There was no statistical difference in various time quantum in terms of BCVA , residual astigmatism, IOL axial view rotation (P>0. 05). 誗 CONCLUSION: For cataract patients, micro-incision phacoemulsification combined with Toric IOL can effectively improve visual acuity, rectify preoperative corneal astigmatism with fair stability.
