In the fight against blindness and visual impairment, Sierra Donor Services recovers, evaluates, processes and distributes donor eye tissue for sight-saving cornea transplants, reconstructive eye surgeries, and research into cures for other eye diseases.  Those diseases include: cataracts, glaucoma and diseases of the retina. Annually, about 1,000 people have their sight restored through corneas provided by Sierra Donor Services Eye Bank. Because of SDS Eye Bank’s commitment to our local communities, we are able to consistently provide life-improving tissue for transplant – ensuring that every person in need receives the Gift of Sight.
