OBJECTIVES To compare clinical outcomes of cases who underwent deep anterior lamellar keratoplasty (DALK) and cases who were converted to penetrating keratoplasty (PKP) from DALK surgery. MATERIALS AND METHODS The records of 54 patients for whom DALK surgery was planned and were operated for different diagnoses between March 2013 and June 2015 were retrospectively analyzed. Patients were divi...

AIMS Evaluation of a new surgical technique for the management of corneal ectasia with peripheral corneal involvement. METHODS Twelve eyes of 12 patients with corneal ectasias and peripheral corneal thinning requiring surgical intervention, including eight patients with combined keratoconus and PMD and four patients of keratoglobus, were enrolled for the study in a tertiary care hospital. All...

THE USE of a Barron artificial anterior chamber (Katena Products, Inc) results in safer and more efficient surgery for deep lamellar endothelial keratoplasty (DLEK) procedures, according to Pavel Studeny MD. Speaking to delegates at the first Cornea Day organised as part of the 10th ESCRS Winter Refractive meeting, Dr Studeny said that the Barron device successfully addresses some of the proble...

BACKGROUND Corneal ulcers often lead to scarring and astigmatism, and significant loss of vision is a common consequence. OBJECTIVE To determine the rate of graft rejection, one of the most serious concerns with this procedure, and to evaluate the recovery of visual function in those patients for whom the operation was successful. METHODS We describe a retrospective study of 33 corneal ulce...

Aims: To analyse the outcome of DALK in patients with keratoconus terms best corrected and uncorrected visual acuity, average K topographic astigmatism. Settings design: Prospective interventional case series study Material methods: 28 eyes diagnosed were evaluated from August 2009 – July 2011 a tertiary eye care hospital. All underwent outcomes assessed on 4 parameters: Average Keratometric re...

OBJECTIVE To evaluate the long term results of Lasik for residual refractive errors (RE) after penetrating keratoplasty (PKP) for keratoconus (KC). DESIGN Retrospective cohort. METHOD Records of 14 consecutive patients (19 eyes) who had Lasik after PKP for KC were retrospectively reviewed. In all eyes with refractive stability and suture removed before Lasik, far distance Visual Acuity with...

Vision loss due to corneal injuries or diseases can be treated by transplantation of human corneal grafts (keratoplasty). However, quality assurance in retrieving and cultivating the tissue transplants is confined to visual and microbiological testing. To identify previous refractive surgery or morphological alterations, an automatic, noncontact, sterile screening procedure is required. Twenty-...

PURPOSE To assess the outcomes of conductive keratoplasty (CK) for patients with complications related to LASIK or photorefractive keratectomy (PRK). DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Sixteen eyes of 15 patients were treated using CK after complications of initial LASIK or PRK surgeries. Five cases are described in detail. INTERVENTION Rehabili...

The formula based on keratometric readings which is generally used is unsatisfactory for fitting contact lenses after penetrating keratoplasty, possibly owing to lack of information on the peripheral corneal toricity. In these studies a photokeratoscope was used to examine the entire graft topography. In all cases the corneal configuration became more normal after suture removal, but a consider...

BACKGROUND High-risk keratoplasties are usually performed after an uninflamed and quiescent interval in corneas with partly regressed blood and lymphatic vessels. We analysed whether the inhibition of post-keratoplasty revascularisation in mice with partly regressed corneal vessels ("intermediate-risk") improves graft survival. METHODS Three interrupted stromal sutures (11-0) in corneas of Ba...
