Clinical study of Toric intraocular lens implantation for correcting cataract patients with high astigmatism

Objective To retrospective evaluate the clinical efficacy of the AcrySof toric intraocular lens(IOL)in correcting pre-operative corneal high astigmatism in cataract patients.Methods This retrospective observational study included 11 eyes from 10 cataract patients with high astigmatism who underwent implantation of an AcrySof toric IOL with cataract surgery.To analysis the outcomes of uncorrected visual acuity(UCVA),the best corrected visual acuity(BCVA),post-operation residual astigmatism,and IOL rotational stability after 1 week,1 month,and 6 months follow-up.Results The UCVA was 0.58±0.29 and BCVA was 0.65±0.30 at final follow-up(6 months).The UCVA was 0.5 or better in 6 eyes(54.5%),and was 0.4 or better in 8 eyes(72.7%).The postoperation residual astigmatism was significant reduced to(0.51±0.36)D from(4.06±1.63)D before surgery(P0.01).There were no statistically difference between the mean residual astigmatism at 6 months postoperative and the mean preoperative anticipated residual astigmatism(P0.05).The mean rotation of the toric IOL was(3.60±1.25)° at 6 months follow-up.All eyes had IOL rotation of less than 5° at final follow-up.Conclusion The results of this review showed that implantation of the AcrySof toric IOL is an effective,safe,and predictable method for managing cataract patients with high astigmatism after strict screening,it provides a beneficial increase in UCVA with the use of toric IOL and can be widely implement.
