A few years ago, a collaborative effort by CIBA Vision, Novartis in Switzerland, and the Cooperative Research Centre for Eye Research and Technology in Australia developed a new polymer called lotrafilcon contact A. It contains a modest 24 percent water yet lenses allows six times as much oxygen to pass through as the best of the HEMA hydrogels do. Lotrafilcon A consists of interspersed micrometer-size bits of two different plastics. One material, a hydrogel, lets water and ions reach the eye surface; the other, called fluorosiloxane, channels oxygen. The combination is as transparent as a conventional contact lens. The ability of a material to convey oxygen relative to its thickness is called transmissibility. Lenses should have a transmissibility of at least 90 barrers for oxygen, according to researchers at the University of California, Berkeley and Indiana University in Bloomington.

CIBA uses molds made of transparent quartz glass, which can be reused, unlike the plastic molds used for hydrogel lenses. A drop of nelfilcon A is placed onto one half of the mold, and the complementary half is suspended a few micrometers away. A circular mask is placed around the edge of the lens, and ultraviolet light is shined through the molds to cure the polymer. The mask blocks the UV light and creates a precise, smooth rim. This allows for a consistent shape with an edge half the thickness of other lenses. A thinner edge reduces what''s known as edge sensation, discomfort caused by the eyelid rubbing against the lens rim. A lens is about 14 millimeters in diameter, but only the center portion, 8 mm across, is shaped to correct vision.
