Description of intervention(s) / exposure
phakic posterior lens implantation to correct refractive error in cases of stable keratoconus
done by surgeons who have at least 20 years of experience.In this study,

the current V4C ICL design was used. Under local anesthesia, dilating agents were administered. For the toric ICL implantation, the axis was marked using Neuhann-Nuijts One-Step Toric Marker (ASICO) while the patient was lying upright to prevent cyclotorsion. In a temporal approach, after injection of viscoelastic material (Provisc, Alcon), a small 3.2 mm clear corneal incision was made and the ICL was injected through this incision into the anterior chamber and allowed to slowly unfold.After the injection and unfolding of the toric ICL into the anterior chamber, haptics were tucked under the iris and the TICL was aligned to the desired axis.

Summary
Brief summary
Patients with keratoconus suffering from poor visual acuity and high refractive errors, so they need any kind of visual rehabilitation. phakic lens implantation is one of the solutions to improve visual acuity in these patients. The purpose of our study is to evaluate visual and refractive outcomes after phakic Visian toric implantable in stable keratoconus. METHODS: this retrospective study investigated toric ICL implantation in 14 eyes of 8 patients with stable keratoconus. Data were collected 6 months after ICL implantation.
