  • Patient interactive fit tool and methodology for contact lens fitting
    Patent number: 9581835
    Abstract: An interactive fit tool and methodology which may be utilized by an eye care professional to improve the efficiency and final outcome in selecting a pair of contact lenses targeted towards a specific patient visual need in the treatment of presbyopia. The interactive fit tool comprises an application which includes images that would allow a patient to decide if he or she desires balanced visual acuity, near biased visual acuity, or distance biased visual acuity. In addition, the interactive fit tool comprises fit guide tables and performs the calculations for vertex distance and spherical equivalent.
