To discuss the result of TORIC intraocular lens (IOL) implantation to correct preexisting astigmatism in patients having cataract surgery.This prospective series case study in Tianjin Medical University Eye Center included 61 eyes of 52 patients with more than 0.75 diopter (D) of preexisting corneal astigmatism having cataract surgery. The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), residual cylinders, and TORIC IOL axis were measured preoperatively, 1 d, 1 month, 3 months post operatively.The UCVA was 0.5 or better in 92% of eyes and 0.8 or better in 78%. The mean refractive cylinder decreased significantly after surgery from (1.92 + or - 0.83) D to (0.35 + or - 0.39) D (P0.01), which was no statistically significance with anticipated residual cylinder (0.37 + or - 0.42) D. The mean TORIC IOL axis rotation was 3.74 degrees + or - 4.71 degrees degrees at 1 d postoperatively, 92% of eyes deviated less than 10 degrees to the anticipated axis, from then on the IOL axis rotated 1.22 degrees + or - 2.53 degrees degrees till 3 months post operation. 98% of eyes rotated less than 10 degrees.The SN60TT TORIC IOL showed good stability. Phacoemulsification and posterior chamber TORIC IOL implantation is an safe and effective option to correct preexisting astigmatism in cataract patients. |
