Sarcoidosis. International Review of SarcoidosiS and Other Granulomatous Disorders. Vol. 1, No.1, September 1984.
This international review of sarcoidosis and other granulomatous disorders is scheduled to appear every six months under the editorship of D. Geraint James, Royal Northern Hospital, London, N7, England. A two-year subscription is $50 (U.S.) for residents in Europe and $60 for residents elsewhere.
Scanning Electron Microscopy of the Eye. By Serge Liotet and Gerard Clergue. Stuttgart, Ferdinand Enke Verlag, 1985. 128 pages, illustrated. $64 (U.S.); $77 (elsewhere).
This is a collection of over 100 scanning electron micrographs taken from the human eye, with captions in German, French, and English.
computer Software IOL Master: version 2.2, 1984.
Type: Menu-driven intraocular lens power calculations, patient database storage, and report generator. Computer: IBM PC, XT, or other IBM-
compatibles running MS-DOS (versions 2.0, 2.1 tested). Format: One 51J4-inch floppy disk; unlimited backups. Documentation: 25-page loose-leaf binder. Price: $300. Source: OphSoft, 7 Sandsbury Rd., Lutherville, MD 21093. Reviewed by MIGUEL LUGO Durham, North Carolina IOL Master is an easy to use and powerful program directed to surgeons who implant intraocular lenses. It utilizes the Sanders, Retzlaff, Kraff (SRK), Binkhorst, ColenbranderHoffer, and multiple regression formulas to calculate the intraocular lens power to use on patients. Although this is an important function, most surgeons already have similar programs in their calculators or computers. The utility of this program is in its information storage and processing abilities. After calculating the intraocular lens power, the surgeon is given the option of saving the information on disk and creating a database. There are subroutines to search and edit this database and to print its entire contents. To learn the most from the information saved, the surgeon at a later date edits a patient's file by adding the actual intraocular lens power used and the final refraction. The program can then analyze the data, present statistics on the predictability of the different formulas, and revise the SRK constant. The documentation is clearly written and successfully guides a novice through the program's use. Because a separate disk must be used for significantly different lenses, multiple program backups are allowed. No 'major bugs were evident after four hours of use. All information can be sent to a printer for a hardcopy. A disadvantage is that there is no provision for changing the formulas, preventing the surgeon's favorite modification of these equations. Like all such programs, a certain amount of time and effort must be investing in setting up the database. The author recommends having u . . • at least 50 patients entered in the database before attempting to analyze the accuracy of the IOL formulas. However, if the user wants more than just intraocular lens power calculations, this program should be of great interest. U
