Effectiveness of Toric Intraocular Lenses for Treating Corneal Astigmatism in Patients With Cataract and Previous DALK
- Conditions
- Corneal Astigmatism in Cataract Patients and Previous DALK
- Interventions
- Device: Customized toric IOL for post-DALK atigmatism
- Registration Number
- NCT03398109
- Lead Sponsor
- Fondazione G.B. Bietti, IRCCS
- Brief Summary
the purpose of this study was to assess the efficacy of custom made toric intraocular lens implantation in patients with simultaneous post-DALK high corneal astigmatism and cataract.
- Detailed Description
Patients undergoing cataract surgery after DALK for keratoconus were enrolled. Total corneal astigmatism (TCA)was assessed by a rotating Scheimpflug camera combined with Placido disk corneal topography (Sirius; CSO, Firenze, Italy). A customized toric IOL (FIL 611 T, Soleko) was implanted in all eyes. One year postoperatively, refraction was measured, the IOL position was recorded, and vectorial and non-vectorial analysis were performed to evaluate the correction of astigmatism.
