Comparison of grafted and non-grafted patients with corneal astigmatism undergoing cataract extraction with a toric intraocular lens implant.

Background: Toric intraocular lenses (IOLs) are advocated as an effective treatment for both regular corneal-based astigmatism and cataract in both non-penetrating keratoplasty and penetrating keratoplasty (PK) patients. The aim of this analysis is to compare postoperative outcomes for both PK and non-PK patients to determine whether or not the past PK is relevant when calculating the appropriate IOL and predicting the postoperative results.

Methods: A retrospective analysis was performed on 14 non-PK and eight PK patients who underwent cataract surgery and astigmatism correction with a Rayner toric IOL.
