Abstract: The present disclosure relates to trial scleral lenses, and the resulting scleral lenses, designed for the asymmetric shape of the sclera and/or its chiral properties. In some embodiments, the scleral lenses are also designed for the specific asymmetry associated with different scleral diameters. In addition, as discussed herein, the scleral shape can vary with different conditions of the eye. By designing a set of trial scleral lenses that takes into account these different asymmetric properties of the sclera, a clinician can be more efficient, fitting more eyes with fewer subsequent modifications. The resulting lenses will also achieve a better fit.

The lens may be structured such that bubbles greater than 0.5 mm in diameter are prevented from forming between the contact lens and the eye. The contact lens may be used in combination with a suitable bioactive agent providing for enhanced visual correction.
