INSTRUMENT AND BOOK SUPPLEMENT 1987
a bi-prism mounted directly on the objective of the Reichert slit lamp. The increased prism-to-contact surface distance makes centration less critical, and virtually eliminates vertical adjustment. Adjustment for axis on a high cylinder cornea is not necessary. Readings are direct in mm Hg, accurate to ±0.5 mm Hg regardless of corneal radius or scleral rigidity. Following measurement, a simple lever moves the biprism out of the optical path for normal slit lamp use. Price on request Non-Contact™ II Tonometer The Reichert Non-Contact™ II Tonometer is designed to quickly and accurately measure intraocular pressure. The straight forward measurement procedure may be accomplished by an assistant. Nothing touches the eye but a puff of air. Patient can relax; no anesthesia, no instrument contact with the eye, no painful after-effects, no risk of crosscontamination. Clinical studies have demonstrated the NCT's high coefficient of correlation with the standard Goldmann Tonometer. The NCT may be stand or table mounted, and is available in black and honey grey. Price on request Applanation Tonometer This Goldmann-type instrument allows tonometric measurement to be expediently incorporated into the normal biomicroscopic examination. Observations may be made with either eye, or binocularly with most patients. The contact piece is designed to utilize the popular technique, allowing easy determination of the standard 3.06 mm applanated area. Readings are in direct mm HG, accurate to ±0.5 mm Hg regardless of corneal radius or scleral rigidity. Models fit the HaagStreit 900 as well as the Reichert™ Slit Lamps. Price on request

Pupil Height Device (PHD) (#970035) The 1W' x 6W' piece has a transparent horizontal slit on the gauge creating a horizontal reflex on the cornea when held against the frame in normal ambient light. A scale on the PHD allows reading the distance between the center of the slit and deepest part of the frame. When reflex is on the cornea's 180° line, this distance indicates the vertical pupil height. Literature available Suggested retail price $6.95 Multifocal Demonstration Set (MDS), #971008 A compact unit designed to assist the dispenser and presbyopic patient in selecting lens corrections for presbyopia based on first hand experience by the patient. The unit neatly stores three frames and several lenses (3 add powers each for bifocals and progressives, 1 add power for trifocals are provided.) A reading chart inside the cover can be used for static as well as dynamic demonstrations. Adjustable frames are also included for use with emmetropic presbyopes and corrected presbyopic ametropes. Suggested retail price $299. Literature available on request

WCO, Inc.
WCO Distometer Designed to measure the vertex distance between cornea and trial or spectacle lenses. Research has established that the trial frame usually places the trial lenses at between 16 and 22 mm from the cornea, while spectacle lenses, when fitted properly, are rarely over 12 mm from the cornea. The change in vertex distance results in a change in the effective power in the lenses. For example, a plus 12.00 trial lens at 19 mm from the cornea must be increased to a plus 13.12 if placed at 12 mm from the cornea. A minus 15.00 lens at 19 mm must be decreased to a minus 13.50 if placed at 12 mm. A Distometer conversion scale is supplied with each instrument. With the speed and precision of the Distometer and the accuracy of the conversion chart, every patient will receive as good, or better, visual acuity with the spectacle lenses as was found with the trial lenses.
