PURPOSE To evaluate the safety and efficacy of customized transepithelial photorefractive keratectomy (PRK) for the correction of iatrogenic ametropia after penetrating keratoplasty (PKP) or deep lamellar keratoplasty. SETTING Eye Clinic, Department of Neurological and Visual Sciences, University of Verona, Verona, Italy. METHODS This study comprised 9 patients who had irregular astigmatism...

Microkeratome-assisted anterior lamellar keratoplasty has emerged as a surgical option for conditions affecting the clarity of the outer 200 mum of the cornea. Herein we describe the outcome of a simple procedure in which the excimer laser can be used to augment deep tissue removal after both recipient bed and donor graft are prepared with the microkeratome. Our noncomparative interventional ca...

PURPOSE To report the effect of intrastromal injection of bevacizumab in an eye with extensive corneal stromal vascularization after deep anterior lamellar keratoplasty. METHODS Bevacizumab (2.5 mg/1 mL) was injected into the deep corneal stroma of an eye with severe and extensive stromal vascularization. RESULTS Corneal vascularization regressed dramatically after deep stromal injection of...

PURPOSE To evaluate the anatomic and functional results of optical pachymetry-guided custom excimer laser-assisted lamellar keratoplasty in keratoconus patients. SETTING Eye Clinic, University of L'Aquila, L'Aquila, Italy. DESIGN Prospective noncomparative case series. METHODS Patients with keratoconus having unilateral surgery using custom excimer laser-assisted lamellar keratoplasty wer...

BACKGROUND Our aim was to demonstrate the publication trends of corneal transplantation in the last decade. METHODS All of the keratoplasty research articles, letters, case reports, reviews and meeting abstracts published between January 2006 and December 2015 indexed on the Thomson Reuters Web of Knowledge were evaluated. A bibliometric filter was used to capture keratoplasty related publica...

Aim: To improve the deep lamellar keratoplasty technique. Method: For the easy and reliable perfomance of deep lamellar keratoplasty (DLKP), detachment of Descemet’s membrane through the corneal limber flap was improved. To expose Descemet’s membrane, the parenchyma was detached by hydrodelamination through a sclerocorneal flap made in the corneal limbs. The parenchyma was removed after the pse...

PURPOSE To report and discuss cases of lamellar keratoplasty using corneas obtained during previous penetrating keratoplasty in keratoconus eyes. METHODS Corneal buttons were obtained from 7 keratoconus patients and stored in a preserving solution for 7-60 days (average, 32.4 days) before use. The recipient eyes comprised recurrent pterygium 3 eyes, primary pterygium 1 eye, pseudopterygium 1 ...

purpose: to assess parameters that had a capability of influencing the rate of big bubble formation during deep anterior lamellar keratoplasty (dalk) in keratoconus. methods: a total of 290 consecutive eyes from 257 patients with keratoconus that underwent dalk using the big-bubble technique were enrolled. the influence of patient age and sex, family history of keratoconus, history of contact l...

purpose: to compare the clinical outcomes following deep anterior lamellar keratoplasty (dalk) for keratoconic patients with vernal keratoconjunctivitis (vkc) and without vkc. methods: in this retrospective comparative study, the records for 262 eyes with keratoconus only (group 1) and 28 keratoconic eyes with vkc (group 2) that underwent dalk were complied. the parameters reviewed included the...
