As of 2013, the World Health Organization estimates that there are 153 million people worldwide who are suffering from uncorrected refractive errors. Common refractive problems are myopia or nearsightedness, hyperopia or farsightedness, astigmatism and presbyopia. While these refractive errors cannot be prevented, they can be managed with corrective eyeglasses or contact lenses and refractive surgery.
Today’s article from the Myopia Institute talks about a new technique that could potentially improve the outcomes of corneal transplant surgeries.
Corneal Transplant Surgery
Corneal transplant surgery, otherwise known as keratoplasty, is a surgical procedure that involves the replacement, in part or in whole, of the cornea. The replacement cornea is donated by people who have passed. Keratoplasty can bring back your vision and can help correct hyperopia and presbyopia in middle-aged to older people.
You may consult your corneal reshaping therapy experts about whether corneal transplant surgery is for you.
The Survival of Corneal Grafts
Researchers have recently reported that injecting a neuropeptide called vasoactive intestinal peptide (VIP) into the eyes of mice enhanced the survival rate of the corneal transplant. The study also listed other benefits of VIP, including accelerated endothelial wound closure, protection of corneal endothelial cells (CEnCs) and a notable improvement in the clarity of the corneal transplant.
CEnCs are responsible for keeping the corneal graft transparent, and VIP helps protect these cells from certain cell deaths. Researchers are also looking into the benefits VIP can provide to the donated corneas. They have reason to believe that vasoactive intestinal peptides can be used to preserve the endothelial cells in these donated grafts, making them more likely to survive the transplant.
Apart from refractive surgery, there are other methods that can be used to treat refractive errors. Alternative methods include the use of ortho-k lenses and other non-invasive visual apparatus.
