A silicone hydrogel contact lens (Avaria Toric, CooperVision) for patients with astigmatism is now available nationwide.
Pleasanton, CA-A silicone hydrogel contact lens (Avaria Toric, CooperVision) for patients with astigmatism is now available nationwide. The lens was launched in June, but demand was so high that it was restricted to a few thousand customers who had fittings scheduled, according to the company.
The toric lens is designed to provide improved visual performance in a broad range of astigmatic eyes, regardless of cylinder power or axis, through the positioning of the lens ballast and the smooth, junctionless surface of the lens. In addition, the lens features a consistent horizontal thickness across the power range to improve lens stability and reduce rotation, and a wide ballast band that completely encircles the optic zone to optimize lens-lid interaction for both orientation and comfort. It includes a naturally wettable lens and technology that retains water, minimizing dehydration and eliminating the need for wetting agents, coatings, or additives.
The contact lens is manufactured from enfilcon A material. Water content is 46%, Dk is 100, and Dk/t is 91. The lens features sphere powers from plano to –6.00 D; a base curve of 8.5 mm; a diameter of 14.5 mm; cylinders of –0.75, –1.25, and –1.75 D; and an axis from 10° to 180° in 10° steps. An expanded SKU range will be launched in the future.
