Clinical Evaluation of Toric Intraocular Lens

Safety and Effectiveness Evaluation of Toric Intraocular Lens

Evaluate efficacy and safety of the toric IOL implanted into aphakic eye with corneal astigmatism after cataract surgery.

Effectiveness

• primary endpoint is visual acuity with pre-determined spherical correction.
• secondary endpoint is UCVA with spherical correction, BSCVA, Refractive Cylinder Correction, Spherical Equivalent, IOL rotation

Safety

• number and percentage of adverse event
