purpose: to evaluate densitometry of crystalline lens after cxl procedure in keratoconic patients. methods: in a quasi-experimental study three-dimensional lens densitometry was performed by pentacam scheimpflug camera at base line and 6 months later. subject group contained patients with diagnosed progressive keratoconus who underwent cxl surgery (n = 40). control group contained aged-matched ...

PURPOSE To evaluate the outcome of collagen cross-linking (CXL) without corneal epithelial debridement in patients treated for progressive keratoconus for whom the standard epithelium-off treatment cannot be applied, as their central corneal thickness (CCT) is less than 400 μm. PATIENTS AND METHODS This was a prospective, uncontrolled, interventional study involving 32 eyes of 30 patients wit...

Keratoconus is a disease characterized by progressive thinning, bulging, and distortion of the cornea. Advanced cases usually present with loss of vision due to high irregular astigmatism. A majority of these cases require surgical intervention. This review provides an update on the current treatment modalities of corneal surgery available for the management of advanced corneal ectasias.

Materials & Methods: Retrospective review of patients who underwent DALK for progressive keratoconus from 2010 to 2013 was done. Patients who completed 2 years of follow up were included. Slit lamp findings, corneal topography and central corneal thickness were analysed.122 eyes of 71 patients were analysed. Uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) were analysed ...

OBJECTIVE The purpose of this study was to evaluate the safety and efficacy of transepithelial corneal collagen cross linking (TE-CXL) with modified riboflavin and accelerated UVA irradiance in thin corneas with pachymetry less than 400 microns at thinnest point, untreatable by epithelium off corneal collagen cross linking (CXL) in adult Pakistani population with progressive keratoconus. METH...

Keratoconus is a progressive corneal thinning of unknown cause in which the cornea assumes a conical shape, with progressive irregular astigmatism and deterioration of visual acuity. The normal anterior corneal surface is prolate, and it could be described as conic (flattening of the radius of curvature from the apex toward the periphery)1. In keratoconus corneas, the steepening of the central ...

In this issue of JOVR, Derakhshan and co-authors 1 describe the results of crosslinking for patients with early keratoconus. Collagen crosslinking is a recently described technique of corneal tissue strengthening using riboflavin as a photosensitizer and ultraviolet A (UVA) radiation to promote the formation of intra-and interfibrillar covalent bonds by photosensitized oxidation. 2 To date, it ...
