The Church is involved in two major efforts that are focused on persons with disabilities- the Vision Treatment Program and the Wheelchair Distribution program.
The Vision Treatment Program
According this the Humanitarian Services Vision Treatment page provides the following description of the program:
Following the example of Christ himself, Latter-day Saint Charities (Humanitarian Services) is committed to helping those who are visually impaired. Our response to the enormous problem of preventable/reversible blindness is to train local, qualified medical personnel to perform eye surgeries and provide equipment that is essential to the procedure.
The Wheelchair Distribution Program
Latter-day Saint Charities (Humanitarian Services), working in partnership with local organizations that serve the disabled, distributes about 40,000 wheelchairs each year in 70 countries. Those who have witnessed a disabled person receiving a wheelchair for the first time report that the joy and tears of gratitude shown by the recipient are often overwhelming.
