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 compare clinical outcomes following penetrating keratoplasty (pk) versus deep anterior lamellar keratoplasty (dalk) for keratoconic patients with vernal keratoconjunctivitis (vkc). methods: in this retrospective comparative study, the records of 69 keratoconic eyes with vkc that underwent pk (n=43, group 1) or dalk (n=26, group 2) were compiled. postoperative best-corrected visual a...

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...

purpose: to determine the long-term visual outcomes and complications of penetrating keratoplasty (pk) performed for keratoconus. methods: hospital records of patients with keratoconus who underwent pk at the ophthalmology center of shaheed sadoughi, yazd, iran, during 1992-2003 were reviewed. we studied records of 84 pk procedures in 72 keratoconus patients. data including best corrected visua...

purpose: to compare visual and refractive outcomes as well as graft survival after penetrating keratoplasty (pk) in keratoconic patients with or without acute hydrops. methods: in this comparative interventional case series, 14 eyes of 14 keratoconic patients with acute hydrops (group 1) and 37 eyes of 37 keratoconic patients with no history of acute hydrops (group 2) underwent pk. visual acuit...

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...
