ABSTRACT

According to numerous estimations, 15% to 29% of patients with cataract have visually significant (≥1.5 D) corneal astigmatism. Cataract surgery has now become a refractive procedure and emmetropia is the expected outcome of surgeons and most patients. To achieve emmetropia, these patients may have combined corneal refractive surgery and spherical intraocular lens (IOL) implantation or toric IOL implantation alone. The aim of this study is to report the clinical results of toric IOLs implantation for preexisting corneal astigmatism correction and compare post-operative rotation of the IOL’s to detect long-term stability. The results from our study show that micro-incision cataract surgery with implantation of toric IOL is a safe, predictable and effective option for correcting pre-existing corneal astigmatism during cataract surgery with long term rotational stability for good visual outcome.
