title: Power changes converting aphakics from hard contact lenses to the B&L SOFLENS.
abstract: The authors refit 20 former hard lens aphakic eyes with the Bausch & Lomb SOFLENS. Ten patients required less soft lens power than the power of the hard contact lens formerly used; five patients required the same soft lenspower; and five patients required more power with the soft lens than with the previous hard lens used. These findings were different than what would have been expected on the basis of the Back-Vertex Power Chart distributed by Bausch & Lomb.
