Patent number: 11921361Abstract: 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.Type: GrantFiled: May 18, 2022Date of Patent: March 5, 2024Assignee: Boston Foundation for SightInventors: Karen G.
