METHODS OF SURFACE TREATMENT FOR ENHANCING THE PERFORMANCE OF A FLOATING PHAKIC REFRACTIVE LENS DESIGN

摘要

A method of preparing phakic intraocular lenses from hydropho-bic materials is described. In this process, the lens is tested to determine whether it can float submerged in an aqueous medium. If it cannot (e.g., if it remains on top of the aqueous medium), the lens is surface treated (for example, by vacuum UV or corona discharge processes) to increase its wetting ability (e.g., to reduce it hydrophobicity). The lenses prepared by this process are also described.
