ABSTRACT:
A fixture for use in refracting an aphakic eye over a properly patient fitted spectacles frame glazed with major spherical component lenses and placed in a position of use upon the patient. The fixture, having trial lens holders for right and left eye refraction, is attached to rims of the spectacles frame for establishing parallelism of the holders with the frame and provision is made for separately adjusting each right and left eye lens holder vertically and horizontally as needed for centering with a corresponding glazed lens. Refraction over the major lens in each case may be conducted with trial lenses placed in the respective holders.
