Purpose: To analyse the reproducibility of corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated intraocular pressure (IOPcc) obtained with the ocular response analyzer (ORA).
Methods: This is a prospective study, nonmasked, of eight successive examinations with the ORA device in 60 normal eyes. Using 30 eyes (one eye per subject), the reproducibility was assessed by comparing the first series of four examinations to the second four and by calculating the within-subject coefficient of variation.
Objective: To analyze graft survival and the outcome of the corneal endothelium after corneal transplantation in a single model to predict the long-term prognosis of these grafts.
Design: Cohort study. Data were recorded prospectively and then analyzed retrospectively.
Objective: To compare 3 techniques used for removing the recipient stroma during anterior lamellar keratoplasty (ALK): the "big-bubble" technique, manual dissection using a crescent blade and slitlamp operating microscope, and microkeratome lamellar cut.
Design: Retrospective comparative cohort study of 69 consecutive ALKs and 69 consecutive penetrating keratoplasties (PKs). Manifest refraction, slitlamp examination, Goldmann tonometry, ultrasound pachymetry, specular microscopy, and confocal microscopy findings were recorded.
Objective: To analyze graft reepithelialization after penetrating keratoplasty using organ-cultured donor tissue.
Design: Retrospective observational cohort study.
Participants: One thousand one hundred thirty-eight consecutive penetrating keratoplasties (1003 patients) performed between 1992 and 2004 were analyzed, and 1003 were included (1 graft per patient was included).
Purpose: To analyze the late changes in refraction, corneal topography, and pachymetry after penetrating keratoplasty.
Methods: We have retrospectively analyzed data of 64 eyes of 56 patients with a clear corneal graft and no other ocular diseases. The eyes were examined soon and several years after all sutures were removed, at 19.
Objective: To analyze the outcome of graft central thickness after penetrating keratoplasty.
Design: Retrospective observational cohort study.
Participants: Eight hundred fifty-six consecutive penetrating keratoplasties (772 patients) performed between 1992 and 2001 were analyzed and 772 were included (1 graft per patient was included).
