Abstract: 

Purpose: This study was performed to evaluate the ability of toric intraocular lenses (IOLs) to correct pre-existing corneal astigmatism in cataract patients.
Methods: Fifteen eyes that had corneal astigmatism of 1.5 diopters (D) or more were enrolled in this retrospective study. Standard superior posterior limbal sutureless approach for phacoemulsification was done and a Staar silicone plate haptic toric IOL (AA4203TF or TL) was inserted through a 3.2 mm incision in the capsular bag.
Results:' After a 6 month follow up the uncorrected visual acuity was 0.25± 0.138 LogMAR, and 100% of patients had a 20/40 or better and 69.2% a 20/30 or better unaided vision. Postoperative refractive astigmatism was 0.75 or less in 69.2%. Mean astigmatism correction was 1.560 for 2.000 and 2.220 for 3.500 toric lenses.
Conclusion: Toric IOLs are safe and reliable tools to correct preexisting astigmatism.
They showed promising results to reduce corneal astigmatism of 1.50 to 3.00. There was no difference in the outcome between Staar AA4203TF and TL IOL.
