Clinical Observation of the AcrySof Toric Intraocular Lens Correction of Corneal Astigmatism

Objective To evaluate the refractive and visual outcome of Toric IOL implantation for correction of pre-existing corneal astigmatism following cataract surgery.Methods 32 eyes of 23 patients were undergone implantation of Toric IOL following regular phacoemulsification.Pre-and post-operative corneal and refractive astigmatisms,and post-operative distance vision were investigated.Statistical analysis was carried out using the paired student t-test when necessary.Results No statistical difference was observed between pre-and post-operative corneal astigmatism(P0.05).Postoperative refractive astigmatism was significantly less(P0.05).The IOLs in 31 eyes rotated less than 5 degrees in 3 month postoperatively.Conclusion Toric IOL implantation is a viable and highly predictable method of correcting the corneal astigmatism.It allows correction without compromising the integrity of the cornea.
