A regional course to update the practicing specialist.
Four medical centers collaborated in the development of a course in ophthalmology to present new information and skills to the practicing specialist who is not associated with a medical center. The course is presented in 8 two-day sessions, scheduled Friday and Saturday, four times a year, on a two-year cycle. Thus, the participant loses only four days a year from his practice. This course differs from most of the postgraduate courses currently being offered in that it is designed to update basic specialty knowledge and skills systematically to improve health care delivery.
Modified suturing contact lens for penetrating keratoplasty.
The authors have previously described a suturing contact lens that protects the corneal endothelium by aiding in the maintenance of the anterior chamber during penetrating keratoplasty. This report describes structural modifications of the suturing contact lens, which improve its stability and effectiveness. An additional configuration for use in corneal lacerations is presented.

Prophylactic therapy of retinal breaks.
Prophylaxis of selected retinal breaks is effective in preventing detachment. Most retinal breaks, however, will not cause detachment and can be safely followed without treatment. This paper reviews the evidence for and against prophylactic treatment of commonly encountered retinal breaks in an effort to arrive at typological guidelines for treatment. Education of patients with high risk of detachment is probably of equal value to cryotherapy or photocoagulation in preserving visual acuity.
The triple procedure: cataract extraction in a different setting.
This article compares and contrasts ordinary cataract extraction, including lens implantation, with cataract extraction and lens implantation in eyes also undergoing penetrating keratoplasty. Variations in cataract extraction technique which are necessary when a keratoplasty is added are described, and differences in an important complication which occurs in both settings, cystoid macular edema, are evaluated.
Maintenance of the anterior chamber during penetrating keratoplasty.
A description of the author's (S.G.K.) technique for penetrating keratoplasty is provided. The salient features include corneal removal, storage, and corneal graft cutting procedures of Kaufman and his co-workers. In addition, a specially designed suturing contact lens is described which allows maintenance of the anterior chamber during penetrating keratoplasty. It is suggested that trauma to the all-important cornea endothelium can be minimized by application of this technique, because it significantly reduces the likelihood of endothelial trauma induced by mechanical contact of the endothelium with intraocular recipient structures during suturing.
Microscope sterility system.
The problem of microscope sterility during ophthalmic microsurgery has generally been managed by using sterilizable handle protectors, or by using some form of plastic sterilizable drape for the entire microscope. Both of these systems have disadvantages. A simple and effective alternative which has been designed for Zeiss operating microscopes and can be modified for other types of instruments is presented. No modification of the microscope is required. The instrument consists of two pieces: a metal bracket which mounts in the accessory shoe of the operating microscope, and a rigid plastic sterilizable portion which is readily attached on the microscope from below with three sterilizable screws. The entire assembly can be attached within 15 seconds. It affords complete sterility protection of the operative field; it provides a sterile surface for handling and moving the microscope; it does not interfere with accessory lighting systerms; and it allows open access to external accessories such as cameras and observer tubes.
