High-Index Material Gets FDA Approval
Paragon Vision Sciences has announced the immediate availability of Paragon HDS HI 1.54, a new FDA-approved GP contact lens material.
HDS HI 1.54, combined with its low specific gravity, will provide many useful benefits to contact lens fitters and their patients, especially when prescribed in aspheric multifocal lens designs, according to Paragon. The company says its HDS HI 1.54 could deliver as much as 1.00D of incremental add power and will prove beneficial in increasing optical zone diameters. HDS HI 1.54 will reduce overall lens mass associated with high myopic prescriptions and could improve overall GP lens comfort and oxygen transmissibility, according to the company.

Semi-Scleral Lens for Irregular Corneas
Tru-Form Optics now offers DigiForm Semi-Scleral contact lenses. The company says the patent-pending DigiForm technology provides the first scleral lens that has specific designs for the five most common irregular corneas.

Design options also include toric, bitoric, quadtoric and multifocal, according to Tru-Form. The lens can be manufactured in Boston XO (Bausch & Lomb), Tyro 97 (Lagado Corporation) or Optimum Extra (Contamac) with made-to-order base curves and powers.

Improved Non-Contact Tonometer
Reichert, Inc. has introduced the Reichert 7, its seventh-generation noncontact tonometer. The Reichert 7 offers many of the features of the company's previous NCTs, while adding features such as a refreshed design, enhanced user-interface and triple-measurement mode.
The Reichert 7 features the industry's only one-touch measurement system, according to the company. Joysticks and trackballs increase exam time, but the self-aligning system of the Reichert 7 allows the doctor or technician to simply position the patient in front of the instrument, press the touch screen and obtain an automatic measurement.
THE REICHERT 7 NON-CONTACT TONOMETER HAS A ONE-TOUCH MEASUREMENT SYSTEM.
The touch screen also features an icon-based operating system that Reichert intuitively designed to take the guesswork out of the procedure. In addition, the "triple-measurement" mode further shortens exam times by taking three successive measurements, eliminating the need to re-position patients for multiple readings.
