Twenty eyes with posterior chamber intraocular lens implants that required secondary capsulotomies were evaluated with the laser interferometer. The interferometric measured preoperative retinal acuity is a good indication as to what the postoperative Snellen visual acuity can be after capsulotomy. Preoperative retinal visual acuity testing is also valuable in helping to decide when a capsulotomy is indicated.

Video monitoring and video recording are useful in ophthalmic microsurgery for self-instruction and improvement, increased interest by operating room personnel, transfer of useful information to other physicians and improvement of technique. Specialized video cameras for such use are expensive. There is, however, a newly-marketed, inexpensive and light-weight video camera, which was designed for electronic newsgathering purposes, and which can be modified for microsurgery application, providing excellent results.
