Being the outermost surface of the eye, it faces continuous stress from dryness, photodamage, infection, and injury; however, like the skin, the cornea regularly refreshes itself by shedding its epithelial cells, which are readily replaced, keeping the ocular surface stable and functional. This regular turnover of the corneal epithelial cells occurs through the stem cells in the limbus, an annular ring of a tissue surrounding the cornea, separating it from the sclera and the conjunctival membrane. The loss of this reserve of stem cells leads to a condition called limbal stem cell deficiency. Treatment for this disorder has evolved from transplanting whole limbal tissues to the affected eye to transplanting laboratory cultured limbal cells. This procedure is called cultivated limbal epithelial transplantation (CLET). Since its start in 1997, more than 1,000 CLET procedures have been reported from around the world, with varying degrees of success. In this paper, we compare the methods of cultivation and the outcomes and discuss some problem areas, use of other cells as substitutes for limbal epithelium, and various carrier materials used in transplantation. Our analysis suggests that CLET as a treatment for corneal surface damage has come of age. We also highlight a simpler procedure (simple limbal epithelial transplantation) that involves cultivation of limbal tissue in situ on the surface of the cornea in vivo and that has outcomes comparable to CLET.<\/jats:p>","DOI":"10.5966\/sctm.2014-0064","type":"journal-article","created":{"date-parts":[[2014,9,10]],"date-time":"2014-09-10T00:25:04Z","timestamp":1410308704000},"page":"1160-1168","source":"Crossref","is-referenced-by-count":45,"title":["Concise Review: The Coming of Age of Stem Cell Treatment for Corneal Surface Damage"],"prefix":"10.1093","volume":"3","author":[{"given":"Charanya","family":"Ramachandran","sequence":"first","affiliation":[{"name":"Centre for Ocular Regeneration, Hyderabad Eye Research Foundation, L.V.
