Microcomputer applications in clinical ophthalmology.

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.

A modified lens glide for intraocular lens implantation.

The sheets glide has been narrowed and bent 30 degrees; this model is shorter than the original design. With rotation the bend produces an effective angle up to 85 degrees for hooking the iris at 12 o'clock during glide removal, and thus allowing the superior lens loop to be simultaneously dropped behind the iris. This narrower and shorter glide is easier to position and less likely to get in the way. The original functions of the Sheets glide are not impaired by these modifications. The modified glide has been especially helpful in patients with small pupils.
