Focus on Tonometers
DIATON TONOMETER
Bicom, Inc.
■ Bicom's transpalpebral Diaton tonometer uses Diaton tonometry, a unique approach to measuring IOP through the eyelid. There is no contact with the cornea and no anesthesia or sterilization is required.
Portability, safety and simplicity make the Diaton tonometer ideal for a wide range of applications: for mass screening of the population, at the patient's bedside, in geriatric homes, in childrens' hospitals, for the military and home use.

TX-F FULL-AUTO TONOMETER
Canon Medical Systems A Division of Canon U.S.A., Inc.
■ Canon uses innovative technology in its TX-F full-auto tonometer. Once a patient's eye is seen on the monitor, the start button can be pressed and the exam is over in seconds.
When operated in a full-auto mode, the TX-F performs alignment, focusing and measuring for one eye and then moving to the other eye in one continuous series of operations. Users simply wait for the printout. The entire process is remarkably quick, and the unit's 3D tracking system helps to ensure that readings are reliable.

THE GOLDMANN APPLANATION TONOMETER, APPLANATION TONOMETER 900 AND PERKINS HAND-HELD APPLANATION TONOMETER
Haag-Streit
■ The average deviation with a Goldmann Applanation Tonometer does not exceed +/- 0.5 mm Hg in any single examination. Other features include: measurements performed in conjunction with other routine examinations at the slit lamp, no massaging effects because repeated measuring does not reduce the ocular pressure, no standardization and calibration difficulties. The IOP in mm Hg is found by multiplying the drum reading by 10, and the small volumetric displacement of 0.56 mm3 increases the intraocular tension by about 2.5%, so scleral-rigidity is not taken into account.
The Applanation Tonometer 900 is a powerful accessory to the Haag-Streit 900 series slit lamps. The tonometer is also compatible with many other brands of slit lamps.
The Perkins Hand-Held Applanation Tonometer is portable, making it easier to examine bedridden and pediatric patients. Based on Goldmann principles and utilizing the original Goldmann or Tonosafe-disposable prisms, the Perkins combines proven technology with the flexibility of a handheld instrument. The Goldmann Applanation Tonometer is on the left side of the figure and the Perkins Tonometer appears on the right.

THE APPLANATION HA-2 AND THE NON-CONTACT KT-800
Kowa
■ Kowa Optimed offers two tonometers; the handheld Applanation HA-2 and the Non-Contact KT-800.
The Kowa Handheld HA-2 is a lightweight instrument that offers the ultimate flexibility and mobility to use the instrument with a single hand, says Kowa. Its patented one-spring mechanism design assures correct readings regardless of patient posture. Built-in illumination enables the instrument to be operated regardless of available light and the direct reading type precision dial requires no conversion table to change readings.
Kowa's newest tonometer, the KT-800, offers 3D auto-alignment function, an electronically operated chin rest, and high-speed print out. Measurements are performed with non-invasive soft air and measurements are not processed if the eye is not sufficiently opened.

THE M3
Marco
■ The Marco M3 is a combination non-contact tonometer, auto-refractor and keratometer. The M3's advanced technology includes: powerful Super Luminescent Diode technology with a highly sensitive CCD camera that provides improved image quality (zonal ring-imaging). This makes it possible to accurately measure patients with cataracts, corneal opacities, IOLs and post-LASIK cases. The M3 also has fully automated eye alignment, tracking and focusing. The auto-fogging system minimizes accommodation throughout the exam. Its tilt screen, motorized chinrest and easy-load paper maximize user-friendly operation. The M3 has a new ergonomic design, integrates with other Marco refraction systems and interfaces with most EMR companies.

PASCAL DYNAMIC CONTOUR TONOMETER
Ziemer
■ The Pascal Dynamic Contour Tonometer is a high-tech digital contact tonometer manufactured by Ziemer Group. Pascal eliminates the errors commonly found with applanation tonometry, including the influence of corneal thickness and corneal rigidity.
The Pascal works by having its cornea-matched tip rest gently on the cornea in such a way as to get the cornea to "relax" into the tip. When this occurs, corneal biomechanics are neutralized and no longer influence the IOP reading. The Pascal has been fully validated in clinical studies that have been published in peer-reviewed journals.

SPAIDE AUTOFLUORESCENCE FILTERS
Topcon
■ Topcon's Spaide Autofluorescence Filters, developed by Richard F. Spaide, M.D., have been optimized to allow for better visualization of fundus autofluorescence. By perfecting the excitation and barrier filters through improved science and state-of-the-art manufacturing processes, the filters are approximately 20 times more efficient than current-generation fundus autofluoresence filters, says the company.
The Spaide filters, used exclusively in Topcon ImageNet systems, require 40% less exposure and produce a more vivid, detailed image of the Lipofuscin material that accumulates in the RPE cells of the retina. These filters will improve tonal contrast, while reducing "noise" in FAF images, says Topcon. They do not stimulate fluorescein or ICG dyes, so photographs can be taken before or after angiography.
