Efficacy of progressive thickness intrastromal corneal ring segments in the treatment of duck phenotype keratoconus.

European journal of ophthalmology - 1 Sept 2021

Arbelaez Juan G, Arbelaez Maria C

Abstract excerpt

PURPOSE: To evaluate clinical outcomes in patients with asymmetric duck phenotype keratoconus implanted with asymmetric progressive thickness intrastromal corneal ring segments (PT-ICRS, Keraring AS, Mediphacos, Belo Horizonte, Brazil), and to demonstrate improved visual acuity and symmetry in corneal flattening. METHODS: This single-center, retrospective, observational study evaluated the clinical outcomes at 1,...
