Study examining results of an experimental protocol used to instruct fifteen patients with peripheral visual field loss caused by retinitis pigmentosa, choroideremia, or Usher's syndrome Type II how to use bioptic amorphic lenses effectively. Under the protocol, participants were trained to use the amorphic lenses only as a spotting tool to obtain information that increased their effective field of view, rather than looking continuously through the lenses. The factors that contributed to the successful use of these lenses and the difficulties encountered are discussed. The results of the study show that bioptic amorphic lenses can expand visual function in the areas of recognition, peripheral detection, tracking, mobility, and visual memory when combined with a comprehensive training program.
