Official Title: Comparative Analysis of the Visual Performance in Patients With Stable Keratoconus After Implantation of the Toric Implantable Collamer Lens (TICL).
Brief Summary: To report on 4-year postoperative safety, efficacy, stability and predictability outcomes(to evaluate the visual, refractive, contrast sensitivity, defocus curve and aberrometric data preoperation, and compare with a similar postoperative outcomes) with the Toric Implantable Contact Lens (TICL) for Stable keratoconus. Investigators will study the four-year follow-up from this standardized, multi-center clinical investigation, support from clinical and optical viewpoints TICL implantation, in stable keratoconus.
