PURPOSE Penetrating keratoplasty and epikeratoplasty have been utilized in the surgical treatment of keratoconus. Comparison of the relative efficacy of each procedure in achieving visual outcomes has not been achieved due to limited numbers of cases and follow-up in previous series. METHODS All patients who underwent either penetrating keratoplasty or epikeratoplasty for keratoconus between ...

AIMS To examine histopathological and immunohistochemical changes in lenticules and host of corneal buttons from patients who previously underwent epikeratoplasty for keratoconus. METHODS 12 penetrating keratoplasty specimens from patients with keratoconus who had previously undergone epikeratoplasty, eight keratoconus, and seven normal corneas were examined. Immunostaining for Sp1, alpha1-pr...

We have had 10 years of successful experience with asymmetric radial keratotomy in keratoconus, designed to flatten the steeper central and paracentral areas of the cornea. We think the procedure is the treatment of choice for types I, II, and selected cases of type III keratoconus. The procedure does not adversely affect the results of subsequent surgery such as aphakic epikeratoplasty, cornea...

purpose: ‏to determine the visual and anatomic outcomes of epikeratoplasty in 7 eyes of 6 patients with keratoglobus. method: in a retrospective interventional case series, seven eyes of six patients with keratoglaobus (kgb) aged 5 to 39 years underwent epikeratoplasty. three patients (3 eyes) had blue sclera, hypermobile joints, and consanguineous parents and 3 patients (4 eyes) had only kgb. ...

PURPOSE To present the excimer laser corneal shaping system (ELCS-S), an add-on device to the Keratom, a commercially available 193-nm excimer laser built by Schwind. METHODS The system is designed for the preparation of donor corneas under sterile conditions using the ultraviolet laser to offer greatest possible flexibility. Lenticules for planolamellar grafting and refractive epikeratoplast...

Pellucid marginal degeneration is characterized by a progressive stromal thinning of the inferior corneal segment, between 4 and 8 o'clock, with a crescentic shape. The area of corneal thinning has a width of about 1 to 2 mm, and it is separated from the corneoscleral limbus by an area of normal corneal tissue. The initial treatment consists of optical correction. However, when the disease prog...
