Filter by:The aim of this study is to evaluate the anatomical and refractive parameters following a single-step transepithelial photo-refractive keratectomy (T-PRK) without the addition of mitomycin-C for the treatment of high myopia of 6 diopters or more.
The purpose of this study is long-term follow up of patients with corneal diseases to analyze the quality of surgical interventions and diagnosis. Corneal ectasia, especially keratoconus, is a corneal disease that leads to an irreversible loss of visual acuity while the cornea becomes steeper, thinner and irregular. For these patients, surgical intervention (e.g. corneal cross-linking) is performed, in case of disease progression. Overall, a long-term follow up is needed to evaluate an early disease progression as well as corneal stability after surgical intervention.
Purpose: To compare the efficacy of topical 0.03% tacrolimus with systemic mycophenolate mofetil (MMF) in preventing corneal allograft rejection after repeat keratoplasty. Design: Prospective, randomized clinical trial Introduction: Repeat keratoplasty continues to be an important indication for corneal transplantation in many centers, and it accounts for up to 41% (varying from 6% to 41%) of all keraptoplasty cases performed. Methods: This study will enroll all patients who are candidate for repeat keratoplasty after a failed penetrating keratoplasty. Group 1 will receive MMF orally 1 g twice daily for the first 6 months and then 1 g daily for the next 6 months, and group 2 will receive topical 0.03 % tacrolimus 3 times a day for 12 months. All patients are treated with topical and oral corticosteroids postoperatively. The participants are observed closely for signs of graft rejection, and the rates of rejection-free graft survival are calculated and compared between the two groups at postoperative month 12
Topical preparations (eye drops) derived from the blood have become a relatively common treatment for more advanced forms of keratopathy. The purpose of this study is to evaluate the effect of two blood components from donors (serum cord blood and serum from adult subject donor peripheral blood) in the treatment of severe keratopathies.
