Five year results of Bowman layer transplantation in eyes with progressive, advanced keratoconus

Abstract

Introduction. Keratoconus (KC) – a multifactorial, asymmetric corneal disorder characterized by progressive corneal protrusion and thinning, leading to increasing visual acuity. Corneal collagen cross-linking (CXL) is the only proven intervention that can halt disease progression in KC, but the corneal thickness of less than 400 µm is considered a contraindication. Penetrating keratoplasty (PK) or deep anterior lamellar keratoplasty (DALK) are treatment options for the advanced cases of KC. In advanced studies, scleral contact lenses are the safe save and effective way of visual acuity optimizing for patients.
Purpose. To study the results after 5 - year of Bowman layer transplantation (BLT) in to the stromal pocket in eyes with advanced keratoconus (KC). Center for Eye Diseases
