Details and patient eligibility

About

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.

Full 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.

Enrollment: 10 patients

Sex: All

Ages: 65 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Corneal suture removal had been performed in all cases at least 1 year before cataract surgery.

Corneal astigmatism was stable at least since 6 months before the cataract surgery

Exclusion criteria

• other ocular pathologies as glaucoma, retinal disease.
