Abstract
A hybrid contact lens includes a substantially rigid center portion having a flexural deformation of about 10% at an applied load of at least about 50 grams and a Dk of at least about 30.times.10.sup.-11 (cm.sup.2/sec) (mL O.sub.2)/(mL mm Hg). The hybrid contact lens also includes a substantially flexible skirt portion connected to the center portion. A method of designing a hybrid contact lens includes determining the applied load that results in a selected flexural deformation.
