To describe effectivness of Toric Intraocular Lenses in reducing spherical and astigmatic errors in patients with Cataracts and previous Penetrating Keratoplasty
Retrospective Case Series Review
Six patients with history of having Penetrating Keratoplasty more than two years in duration and Cataracts were offered the option of Toric Intraocular Lens at time of their Phacoemuslification. Only patients that had reliably consistent measures of their astigmatism using IOL Master, Pentacam, and Nidek Auto Keratometry were offered the Toric Intraocular Lens.
Average reduction of spherical and astigmatic error from Preoperative and Two week Postoperative status was 6.5 and 4 Diopters respectively (P<0.05). All patients were very satisfied with their visual outcome.
Toric Intraocular Lenses are an effective modality in patients with Cataracts and previous history of Penetrating Keratoplasty. It is important that the astigmatism is measured reliably using alteast three diagnostic instruments in order to confidently predict significant reduction in spherical and astigmatic error.
