Cadaveric donor tissue can be used unless the donor is suspected of having a communicable disease. (msdmanuals.com)

Corneal opacities sit in this residual category, and it has been my life's ambition to tackle this form of vision impairment. (iapb.org)

It can restore or improve vision, lessen pain, and possibly improve the appearance of the cornea if it is white and scarred, all leading to a better-quality life. (hsa.ky)
A cornea transplant may restore vision, reduce pain, and improve the appearance of a damaged or diseased cornea. (marketresearch.com)

For those aged 18-50 years, retinal dystrophies (37%), congenital eye anomalies (14%) and myopic degenerations (13%) were the most common causes. (who.int)

The cornea and its stromal stem cells themselves appear to be "immune privileged," meaning they don't trigger a significant immune response even when transplanted across species, as in the Pitt experiments. (news-medical.net)
[ 1 ] As corneal edema progresses and worsens, first stromal and then intercellular epithelial edema develops. (medscape.com)
The migrated cells reduce the corneal stromal edema and vision improves. (msdmanuals.com)

Exponential rise in the use of medical devices on account of continued advances in design and superior operative care has led to increase in the use of artificial cornea or keratoprosthesis in the recent years. (medgadget.com)
In addition, lack of availability of human cornea donor has influenced the adoption of artificial cornea, thereby fuelling growth of the keratoprosthesis market. (medgadget.com)
For the first time in India, researchers have successfully 3D printed an artificial cornea and transplanted it into a rabbit's eye. (indiatimes.com)

In fact, LVPEI's eye banking network meets the corneal supply needs of many partners across India. (iapb.org)
The previous day, her Government had stated concern at the seizure by the Dutch customs authorities of a shipment of the generic medicine losartan, en route from India to Brazil. (who.int)

Corneal scars are permanent, so the best available solution is corneal transplant," Dr. Funderburgh said. (news-medical.net)
In the next steps, the researchers intend to use the stem cells to treat lab animals that have corneal scars to see if they, too, can be repaired with stem cells. (news-medical.net)
