Actual (reported)Several methods have been developed to address and reduce preexisting astigmatism. The refractive results associated with the use of toric IOLs are likely to be more predictable. Other advantages of toric IOL include absence of need for any additional astigmatic correction procedure during cataract surgery, faster visual recovery as well as the reversibility of the procedure. There has not been any trial carried out to evaluate the results of toric IOL in either the investigators local population or in East Asia. Hence, the investigators set out to evaluate and compare the efficacy, safety, predictability and stability of the STAAR and Alcon toric IOL in Asian eyes.
