BACKGROUND A new procedure to correct myopia that does not disturb the cornea in the optical zone and avoids injuring the corneal epithelium could be a key advance in corneal refractive surgery. The aim of this study is to observe the refractive change in the adult rabbits undergoing femtosecond laser-assisted multilayer intrastromal ablation in the mid-periphery of the cornea without injury of...

PURPOSE To introduce a novel, noninvasive technique to determine the depth and extent of anterior corneal stroma changes induced by collagen cross-linking (CXL) using quantitative analysis of high-resolution anterior-segment optical coherence tomography (OCT) post-operative images. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS Two groups of corneal cross-sectional im...

Purpose: To evaluate the efficacy of different modalities of antifungal agents in the treatment, clinical features and therapeutic outcome of fungal keratitis Design: Retrospective observational case series. Methods: The study reviewed 251 eyes of 246 patients treated for moderate and severe fungal keratitis in the period from 2010 to 2015. The diagnosis of fungal keratitis based on the clinica...

PURPOSE To evaluate the efficacy of combination therapy of a single intrastromal injection of amphotericin B and topical fluconazole in resistant cases of fungal keratitis, and also topical amphotericin B as monotherapy in terms of the duration of the recovery period and toxic drug effects. METHODS This retrospective 2-year study reviewed 68 cases of unilateral fungal keratitis diagnosed by c...

A novel approach for applanation-free femtosecond refractive surgery with the help of a contact liquid layer is presented. A laboratory device for performing corneal procedures is described based on a femtosecond-laser system which has been tested and evaluated by processing ex vivo pig eyes. With its help, flap cuttings for different flap thicknesses were performed. The accomplished corneal su...

Purpose. The purpose of this review is to provide a summary of laser refractive surgery and corneal inlay approaches to treat presbyopia in patients after cataract surgery. Summary. The presbyopic population is growing rapidly along with increasing demands for spectacle independence. This review will focus on the corneal-based surgical options to address presbyopia including various types of co...

K eratoconus is a bilateral, asymmetric, chronic, initially progressive ectasia of the cornea characterized by steepening, distortion, and thinning of the apical cornea as well as corneal scarring. Intrastromal corneal ring segments (Intacs; Addition Technology Inc, Sunnyvale, California) is 1 treatment option available for patients with keratoconus, especially those with contact lens intoleran...
