The Long-term Outcome After Toric Intraocular Lens Implantation

The Long-term Outcome After Cataract Surgery With Toric Intraocular Lens Implantation

Corneal astigmatism is refractive error that impairs uncorrected visual acuity. When patients undergo cataract surgery, implantation of toric IOL is deemed the most effective choice for correcting corneal astigmatism and reducing postoperative spectacle dependence. Previous studies report that the visual effects and rotational stability of toric IOLs are well maintained over 1- or 2-year follow-up periods. However, the long-term changes in the effects of toric IOLs remain unclear.

Previous studies report that the visual effects and rotational stability of toric IOLs are well maintained over 1- or 2-year follow-up periods. However, there is a long-term against-the-rule (ATR) change of corneal astigmatism with aging，which influences the long-term outcomes of refractive surgery. The long-term changes in the effects of toric IOLs remain unclear. This study aim to observe the clinical effect of Toric IOL implantation in the correction of corneal astigmatism.
