Bookshelf The drawback of silicone hydrogel lenses is their tendency for the lens to collect more debris and protein deposits from your tears. Over the last decade, CL manufacturers have provided a variety of scleral contact lens (ScCL) designs that have a wide range of applications.33,34 Current ScCLs are manufactured using high Dk materials (e.g., fluorosilicone acrylate). Silicone hydrogel lenses are a more porous type of soft contact lens than regular hydrogel lenses, allowing more oxygen to enter the cornea. Evaluation of solution toxicity associated with lens care products during silicone hydrogel lens wear. Etafilcon A attracts the highest amount (approximately 1300 g/lens) [ 41, 50] while all other HEMA-based lenses deposit typically less than 100 g/lens lysozyme. . More recently Avaira (enfilcon A, CooperVision, Inc) has been released.
