AIMS To evaluate visual function and vision specific health status in patients undergoing penetrating keratoplasty for keratoconus. METHODS A prospective longitudinal study measuring logMAR visual acuity, contrast sensitivity, disability glare, binocular visual field, stereoacuity, and subjective visual function (VF-14) was conducted on 18 patients with keratoconus undergoing penetrating kera...
Background and Aim: Penetrating Keratoplasty is the final treatment of a considerable percent of corneal diseases. Besides, it has been the most common human tissue-transplant during the past forty years. Because of limited regional studies in our country, the present study was carried out to evaluate indication and related causes of keratoplasty during 2 years (20 September 2000–20 September 2...
OBJECTIVES Study aims to evaluate the indications and surgical techniques for corneal transplantation and to report changes in trends for preferred keratoplasty surgical techniques. METHODS Clinical records of 815 consecutive corneal transplantations between January 1, 2004 and December 31, 2014 in Haydarpasa Numune Training and Research Hospital Eye Clinic were analyzed and classified into s...
Purpose To report two cases of spontaneous Descemet's membrane detachment (DMD) and dehiscence following penetrating keratoplasty (PK). Case Reports Spontaneous DMD or Descemet's membrane (DM) dehiscence following PK is a rare occurrence. Here, we describe two cases of such an occurrence following PK arising from the graft-host interface. A possible causative relation between DMD/dehiscence a...
purpose : glaucoma following penetrating keratoplasty (pk) continues to be a serious problem that may ultimately become sight threatening. knowledge of the risk factors for development of glaucoma following pk, such as preexisting glaucoma, pseudophakia, aphakia, and previous pk, can limit the occurrence and improve the outcome of the keratoplasty. the management of postkeratoplasty (post-pk) g...
OBJECTIVE To compare outcomes between penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) in patients with keratoconus. DESIGN Retrospective cohort study. METHODS Data of 90 DALK and 49 procedures from conversion to PK, performed by a single surgeon (R.D.) from 2006 to 2011 were analysed. Outcomes on corrected distance visual acuity (BCVA), astigmatism, time to firs...
BACKGROUND Toric intraocular lenses (IOLs) are advocated as an effective treatment for both regular corneal-based astigmatism and cataract in both non-penetrating keratoplasty and penetrating keratoplasty (PK) patients. The aim of this analysis is to compare postoperative outcomes for both PK and non-PK patients to determine whether or not the past PK is relevant when calculating the appropriat...
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...
The concept of lamellar keratoplasty (LK) is that of targeted lamellar replacement of corneal tissue while retaining normal cornea. It involves replacing anterior stroma at different deepness with an anterior lamellar keratoplasty (ALK). Despite the significant advantages of LK surgery, penetrating keratoplasty (PK) remains the most common procedure, largely because lamellar surgery is more tec...
