FAIRPORT, N.Y. --CooperVision, a unit of The Cooper Companies, Inc. [NYSE: COO], has expanded the parameters of its Biofinity silicone hydrogel contact lenses. The new sphere powers, minus lenses now range from -0.25D to -10.00D. Biofinity monthly replacement lenses feature CooperVision’s unique AquaForm technology.

AquaForm technology forms hydrogen bonds with water molecules to create a naturally hydrophilic contact lens that retains water within the lens. AquaForm technology also incorporates longer siloxane chains, which means less silicone needs to be incorporated into the lens material to achieve high levels of oxygen transmissibility, the company said, adding, “This optimizes the relationship between oxygen and water, and creates a softer, more flexible lens material that stays moist.”

“With AquaForm technology, the wettability of Biofinity lenses is inherent within the lens material itself. This eliminates the need for additives, coatings, or wetting agents, and results in excellent initial and all-day comfort,” said James Gardner, director of marketing, CooperVision.

The aspheric front surface lens design improves visual performance, and the single base curve and back surface design enables fast, easy alignment and a quicker fitting process. A patented molded round edge reduces conjunctival interaction, resulting in optimized wearing comfort for the patient.

Biofinity is manufactured from comfilcon A material. The water content of Biofinity is 48 percent, Dk is 128, and Dk/t is 160. The lens also features a base curve of 8.6mm, and a diameter of 14.0mm. It is now available in sphere power ranges of -0.25D to -6.00D in 0.25D steps and -6.00D to -10.00D in 0.50D steps.

“Due to the success of CooperVision’s Biofinity lenses, we’re committed to expanding our portfolio and bringing additional silicone hydrogel products to market later this year, including a two-week hydrogel sphere,” added Gardner.
