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 Corneal topography and thickness has clinical importance in contact lens fitting and refractive surgery, however repeated measurement of corneal thickness and curvature is complicated by the natural phenomenon of diurnal variation. Our aim was determine diurnal variations of central and paracentral corneal thickness and curvature over a period of ten hours. MATERIALS AND METHODS Cor...

K eratoconus early detection (screening) and diagnosis requires an in-deep corneal analysis with different techniques; slip lamp assessment, corneal topography and corneal tomography are the most commonly accepted to detect clinical signs and assess anterior and posterior corneal surface and global corneal pachymetry. However, keratoconus early detection and definitive diagnosis are two differe...

PURPOSE To highlight two cases of keratoconus with significant variations of corneal curvature during pregnancy that reversed several months after delivery. METHODS Case reports and literature review. RESULTS Two women experienced a significant decrease of corrected distance visual acuity during pregnancy. Evaluation of corneal topography by Scheimpflug imaging revealed transitory variation...
