Silicone Hydrogel Lenses Gaining Ground
In less than a year, the number of U.S. eyecare practitioners who say they’re very familiar with silicone hydrogel contact lenses has jumped from 32% to 43%. In addition, 70% of the 348 practitioners responding to a CIBA Vision e-mail survey say they already fit silicone hydrogel lenses; another 22% say they plan to do so in the next 90 days.

Magnetic Fluids Studied for Retina Repair
Injectable magnetic fluids, under development at Virginia Polytechnic Institute, may help surgeons repair torn or detached retinas. Adding tiny particles of cobalt or magnetite to silicone-based fluid and then exposing it to an external magnetic field could make repairs easier and more precise, say researchers reporting at the American Chemical Society meeting.

Abstract: Oxygen Transmissibility, Keratitis and Inflammation
Receptors for lectins and probably for Pseudomonas aeruginosa on the surface of the corneal epithelium are exposed in higher numbers in patients wearing low Dk/t contact lenses as compared to high Dk/t lenses. The rate of bacterial keratitis and inflammation, such as sterile infiltrates, seems to be lower with high Dk/t silicone hydrogel lenses. Nilson, SE. Bacterial Keratitis and Inflammatory Corneal Reactions: Possible Relations to Contact Lens Oxygen Transmissibility. The CLAO Journal; 28(2):62-65 (2002).

Fitting Tip: The Power of Power
Posterior aspheric multifocal GP contact lenses are better than ever and increasingly in demand. As the power gets higher in minus lenses, you may lose “add” in the lens; as the power gets higher in plus, you may gain “add.” Keep this in mind for your high myopes and hyperopes. Also, as the base curve (posterior apical radius) gets steeper, you will have more “add” as well. Of course, this assumes that the manufacturer uses the same eccentricity across the power and base curve range.
