Prokera® therapeutic contact lenses
The Prokera® contact lens is a specially prepared layer of amniotic membrane which is placed in contact with the cornea for several days to promote healing in conditions with poor, incomplete, or stalled out corneal surface healing. These include neurotrophic ulcers, abrasions, erosions, filamentary keratopathy, limbal stem cell deficiency, corneal dysplasia, etc. Prokera® is felt to work by releasing a complex mixture of growth factors to promote healing and by providing the structure to direct the healing forces in the proper direction. It is fairly comfortable and is covered by insurance. It may even be repeated from time to time as necessary.
