This tool assists eye care professionals in determining the optimal parameters for toric soft contact lenses manufactured by CooperVision. These lenses correct for astigmatism, a refractive error where the eye’s cornea or lens is irregularly shaped, causing blurred vision at both near and far distances. The calculation involves considering the patient’s spectacle prescription, including sphere, cylinder, and axis measurements, and converting these into appropriate contact lens power and orientation.
The availability of such a calculation aid streamlines the lens fitting process, potentially improving fitting success rates and patient satisfaction. Accurate calculations contribute to better visual acuity and comfort for individuals with astigmatism. Historically, fitting toric lenses involved more trial and error. Contemporary aids enable a more precise initial lens selection, reducing chair time and inventory requirements for practitioners.
