Medicina regenerativa y superficie ocular

in the last few years, an extraordinary advance has taken place in the knowledge about several biomedical branches as is the case of cellular biology, which has remarkably encouraged the development of a new medical branch called regenerative medicine. this medical discipline is fundamentally based on the new knowledge on the stem cells and their capacity to become cells for different tissues. one of the most interesting structures for the regenerative medicine is the ocular surface. in the last few years, significant advances have been achieved in the field of the ocular surface reconstruction with regenerative procedures. some cell cultures of the human corneal epithelium are being used to treat limber insufficiency, to reduce the incidence of haze-type opacities after photorefractive keratectomy, to speed up the curing process and avoid the occurrence of leukomas in patients with persistent epitelial defects, and to decrease the incidence of corneal opacities in patients undergoing photorefractive keratectomy due to different corneal dystrophies.
