Vision quest.

Women who receive cornea transplants are more likely to reject them if the donors are male, freelance writer Amber Dance reported in "A view to better cornea transplants" (SN: 9/3/16, p. 4). "Can tissue transplant[s] be modified somehow to cause less reactions?" asked online reader WendyVerdades.

Treatments that suppress the immune system's response to the foreign corneas, such as steroid eye drops, can help prevent or reverse rejection. Dance says.

However, scientists are working on a host of experimental treatments that don't require donor corneas to overcome the rejection problem. Approaches include growing new corneas from stem cells (SN Online: 3/9/16) and creating synthetic corneas using cornea cells and hydrogel.
