PURPOSE To compare the quality of vision (straylight and contrast sensitivity) after femtosecond laser-assisted Descemet stripping endothelial keratoplasty (FS DSEK) and penetrating keratoplasty (PK). DESIGN Prospective, randomized clinical trial. METHODS setting: Multicenter (5 ophthalmic centers in The Netherlands). study population: Eighty eyes of 80 patients with corneal endothelial dys...

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...

PURPOSE To report the recurrence of keratoconus 49 months after deep anterior lamellar keratoplasty (DALK). CASE REPORT A 21-year-old man with history of bilateral keratoconus who had undergone DALK in his right eye, presented with gradual visual loss 49 months after corneal transplantation. Slit lamp biomicroscopy revealed graft ectasia together with Vogt's striae in the posterior stroma and...

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, ...

OBJECTIVE To determine the incidence of acute endophthalmitis following penetrating keratoplasty (PK) over time. METHODS A systematic review of English-language articles was conducted by performing a broad search of the PubMed database from 1963 through March 2003 using such keywords as penetrating keratoplasty, endophthalmitis, and postoperative complication. Additional studies were identifi...

Post-PK glaucoma is an important cause for irreversible visual loss and graft failure after penetrating keratoplasty. The etiology for this disorder is multifactorial and with the use of new diagnostic equipment it is now possible to elucidate the exact pathophysiology of this condition. A clear understanding of the various mechanisms which operate during different time frames following keratop...

OBJECTIVE This study sought to compare graft survival, graft rejection and the visual acuity outcome of endothelial keratoplasty (EK) with repeat penetrating keratoplasty (PK) after failed PK. METHODS A systematic literature search with subsequent screening of the identified articles was conducted to obtain potentially eligible randomized clinical trials (RCTs) and comparative cohort studies....

PURPOSE To compare outcomes after penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) for keratoconus in the United Kingdom. METHODS Patient outcome data were collected at the time of transplantation and at 1, 2, and 5 years after surgery. Data were analyzed by Kaplan-Meier survival curves, Cox regression, and binary logistic regression to determine the influence of s...

purpose : to evaluate indications, risk factors and outcome of repeat penetrating keratoplasty (pkp) at a tertiary referral eye care center methods : in this retrospective study, medical chart of patients who underwent repeat pkp at labbafinejad medical center between january 2004 and december 2009 were reviewed. results : a total of 1,859 corneal transplantations were performed on 1,624 eyes d...
