Abstract:
An Apple II computer was programmed for use as a clinical tool in ophthalmology. Currently, eleven distinct programs compose the Ophthalmology Program Library (OPL). These are used in diagnostic and therapeutic situations and are based on equations in physiologic optics. Problems in intraocular lens power calculation, astigmatism control, and spectacle over-refraction with spherocylinder addition (among others) are discussed. To demonstrate the usability of such a system, programs concerned with postcataract extraction astigmatism are discussed in depth. Practicing ophthalmologists should find this system of clinical value.
