Macular Corneal Dystrophy Clinical Trial
Official title:
Fresh Corneal Lenticule Implantation in Macular Corneal Distrophy With Relex-Smile Surgery
The aim of the study is to examine the effect of fresh corneal lenticule implantation as allogenic graft taken from myopic patients to implanted in patients with macular corneal dystrophy using Visumax Femtosecond Laser Smile module surgery.
Macular Corneal Dystrophy is a severe form of stromal corneal dystrophy characterized by bilateral cloudy regions within hazy stroma and eventually severe visual impairment. Most cases of MCD are caused by mutations in the CHST6 gene encoding a protein involved in the production of keratan sulfate, which plays a role in the maintenance of corneal transparency. According to biomechanical instability of corneal metabolism (abnormal increase collagenase activity, decrease proteinase inhibitors, excessive premature keratocyte apoptosis, increase cytokine binding) at corneal dystrophies. Fresh Corneal Lenticule and autologous serum contains live stem cells that produce keratocytes, collagen fibers, extracellular matrix which contribute to the regeneration of the cornea, and all this results at increasing of corneal transparency and visual acuity in patients with corneal macular dystrophy. ;
