The Rocky Mountain Lions Eye Bank fulfilled the wishes of 1,876 donors in 2011, a total that increased substantially from the 2010 total of 1,672. These donors all came from the eye bank's service area of Colorado and Wyoming. A quick look at the eye tissue transplantation figures is below. More than 600 of the transplantable tissues went to recipients in Colorado and Wyoming. The remaining tissues were placed with surgeons throughout the United States and with international transplant programs.
