Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick anterior lamellae (diameter, 10mm; thickness, 500μm). The laser cuts were made using an LDV ...

purpose: to investigate indications and methods of surgery in corneal transplantation in labbafinejad medical center from 2007 to 2009. methods: records of 1083 patients who had undergone corneal transplantation from 2007 to 2009 were reviewed. age, sex and indication and type of surgery were evaluated. results: patients included 709 (65.5%) male and 374 (34.5%) female subjects with mean age of...

We report a case of pharmacologic regression of Urrets-Zavalia syndrome, following deep lamellar keratoplasty for severe keratoconus. Sympatholytic and parasympathomimetic drops were administered and a progressive reduction of mydriasis and restoring of pupillary kinetics were observed. Four years after surgery, it was resulting in only slight residual anisocoria.

Over the last decade there has been a paradigm shift from penetrating keratoplasty (PKP) to lamellar keratoplasty for the management of primary as well as acquired corneal ectasia. Several treatment modalities have emerged including collagen cross-linking, intrastromal implants, laser vision correction, and recent techniques in central and peripheral lamellar keratoplasty. This article reviews ...

PURPOSE Each year, over 8,000 corneal transplantation surgeries are performed in China. Unlike developed countries, which have established standard requirements for operative experience for corneal specialists, little information exists on surgical training for keratoplasty in China. The aim of this study was to assess the keratoplasty experience of Chinese corneal specialists and to characteri...

PURPOSE To analyze the 6-month anterior and posterior topographic changes of the cornea after deep lamellar endothelial keratoplasty. METHODS Orbscan topographies of 22 eyes from 21 patients with corneal decompensation were retrospectively analyzed: 11 eyes received a 9-mm scleral access incision (large-incision group) and 11 eyes received a 5-mm scleral access incision (small-incision group)...

OBJECTIVE To assess the cost-utility of posterior lamellar keratoplasty (PLK) techniques, including deep lamellar endothelial keratoplasty, Descemet stripping endothelial keratoplasty, and Descemet stripping automated endothelial keratoplasty, in the treatment of corneal endothelial diseases. DESIGN Cost-utility analysis based on a Markov model. PARTICIPANTS Cohort of 100 patients waiting f...
