purpose: to report a case of bilateral kertatoconus who presented with acute comitant esotropia after penetrating keratoplasty in the fellow eye. patient and findings: a 17-year-old male with keratoconus underwent penetrating keratoplasty in his right eye. he experienced diplopia after removal of the patch from the operated eye 12 hour postoperatively due to esotropia in his left (unoperated) e...

PURPOSE To evaluate the success rate of highly gas permeable scleral contact lenses (SCL) for visual rehabilitation after penetrating keratoplasty (PK), over a period of up to 9 years. METHODS A total database of 31 consecutive patient fitted with SCL between January 2004 and December 2009 was retrospectively reviewed. Demographic data, etiology prior to lens fitting, visual outcomes, follow ...

purpose: to assess the results of combined penetrating keratoplasty and cataract extraction by extracapsular extraction versus phacoemulsification and to compare outcomes and complications. methods: in this interventional retrospective study, 76 eyes that had undergone triple surgery were included. cataract surgery was done in two different methods of extracapsular extraction and phacoemulsific...

purpose: to evaluate corneal hysteresis and corneal resistance factor in penetrating keratoplasty grafts in a group of keratoconic eyes using the ocular response analyzer (ora) and to evaluate the relationship between donor size, donor-recipient disparity and central graft thickness (cgt), and ora parameters. methods: this cross-sectional study was conducted on 34 eyes of 34 keratoconus patient...

OBJECTIVES To investigate visual outcome and postoperative complications in patients undergoing Descemet membrane endothelial keratoplasty with graft failure after penetrating keratoplasty. MATERIALS AND METHODS A retrospective analysis was performed with 5 patients who underwent Descemet membrane endothelial keratoplasty after failed penetrating keratoplasty. Intraoperative and postoperative...

Penetrating keratoplasty (PK) has emerged as a relatively safe means of restoring vision in corneal opacities and irregularities. Astigmatism is the most common cause of suboptimal vision after corneal transplantation despite a clear corneal graft.1,2 Based on several studies,3615%–31% of patients undergoing PK may develop postoperative astigmatism greater than 5 diopters (D). The astigmatism c...

PURPOSE To evaluate corneal biomechanical properties in eyes that had previously undergone penetrating keratoplasty (PK) using the ocular response analyzer (ORA). METHODS We recruited 26 patients who had received unilateral PK. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and cornea-compensated intraocular pressure (IOPcc) were mea...

AIMS The study was designed to investigate the results of penetrating keratoplasty (PK) for pseudophakic corneal oedema (PCO). METHODS Retrospective analysis of 80 consecutive patients (82 eyes) who underwent PK for PCO between the years 1980-1992 with a minimum follow up of 12 months. RESULTS PKs for PCO have accounted for as many as 20% of all grafts performed in the hospital in recent ye...

INTRODUCTION We describe a case of refractory Pasteurella Canis keratitis that initially failed antimicrobial treatment but was successfully treated with a conjunctival flap followed by a penetrating keratoplasty. CASE DISCUSSION A 70-year-old male had persistent corneal edema related to previous herpes zoster keratouveitis with visual acuity of 20/400. An endothelial keratoplasty was perform...
