The occurrence of pseudoexfoliation (PSX) following penetrating keratoplasty for keratoconus is reported in three eyes of two patients. The patients' ages at keratoplasty were 37, 40, and 31 years, and PSX was first observed 5, 4, and 6 years following keratoplasty. The donor age was 76, 81, and 81 years. Possible explanations for the occurrence of PSX after keratoplasty include mere coincidenc...

BACKGROUND Candida glabrata endophthalmitis following keratoplasty is rare and almost always associated with positive donor rim culture. CASE PRESENTATION A 63-year-old patient, diagnosed Fuch's endothelial dystrophy in both eyes underwent a penetrating keratoplasty in his right eye. He had multiple underlying medical problems, which included diabetes mellitus, hypertension, hypoadrenalism on...

PURPOSE To improve the visual acuity of patients with progressive keratectasia following laser in situ keratomileusis (LASIK). METHODS Five eyes of four patients underwent penetrating keratoplasty for ectasia after LASIK: In one patient the second eye was operated on 10 months after the first keratoplasty. The pre- and postoperative refraction, best spectacle-corrected visual acuity, and topo...

PURPOSE To report the outcome of Descemet stripping automated endothelial keratoplasty (DSAEK) for bullous keratopathy after Sato anterior-posterior radial keratotomy (APRK). METHODS The clinical records of patients who had DSAEK surgery for bullous keratopathy after APRK were reviewed. RESULTS Five eyes of 4 patients (4 men) were included. The mean age at DSAEK surgery was 81.8 ± 7.1 years...

purpose: to compare corneal hysteresis and resistance factor after penetrating keratoplasty (pk) and deep anterior lamellar keratoplasty (dalk) using anwar’s big-bubble technique using the ocular response analyzer. methods: forty-five pk eyes and 23 dalk eyes with keratoconus were compared in terms of corneal hysteresis (ch), corneal resistance factor (crf), goldmann-correlated intraocular pres...

deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...

purpose: this study evaluated the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (pk) in keratoconus-affected patients. methods: a total of 252 consecutive keratoconic eyes that underwent pk were reviewed in this retrospective interventional case series. donor data included age and sex, cause of death, death-to-preservation time...

purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

A 39-year-old woman presented to our hospital with a history of photorefractive keratectomy (PRK), performed two weeks prior; slit-lamp examination revealed diffuse conjunctival congestion, corneal ulcer and stromal infiltration. After 5 days of antifungal and antibacteric treatment, the infiltrate progressively increased so that a therapeutic penetrating keratoplasty was necessary. The microbi...

Introduction Urrets-Zavalia syndrome is an uncommon complication of the deep anterior lamellar keratoplasty in keratoconus. The manifestations of this syndrome are an irreversible mydriasis, iris atrophy and secondary glaucoma. Case report Deep anterior lamellar keratoplasty was done for keratoconus with a presumably healed corneal hydrops in a 21-year-old Caucasian man. The graft remained cl...
