CooperVision Toric Calculator

Astigmatism, a common vision problem caused by an irregularly shaped cornea or lens, can make it challenging to find the perfect contact lenses. Toric lenses are specifically designed to address astigmatism by providing different powers in various meridians of the lens. If you’re looking for a simple and effective way to determine the right lens parameters for your prescription, look no further than the CooperVision Toric Calculator.

Coopervision Toric Calculator Formula

This CooperVision Toric Calculator is designed to provide recommended contact lens parameters for toric lenses based on the user’s input values of cylinder and axis. The formula used in the calculator takes into account the following:

Base Curve: A fixed value of 8.7mm is used as the base curve for the recommended lens parameters. The base curve represents the curvature of the contact lens, which affects how the lens fits on the eye.

Diameter: A fixed value of 14.5mm is used as the diameter for the recommended lens parameters. The diameter affects the overall size and coverage of the contact lens on the eye.

Sphere: The sphere value is calculated based on the provided cylinder value. If the cylinder value is greater than or equal to -2.25D, a sphere value of -0.25D is recommended. If the cylinder value is less than -2.25D, a sphere value of -0.5D is recommended. The sphere value indicates the lens’s power required to correct myopia (nearsightedness) or hyperopia (farsightedness).

Cylinder: The user-provided cylinder value (in diopters) is used to recommend the lens parameters. The cylinder value indicates the lens’s power required to correct astigmatism, an irregular curvature of the eye’s cornea or lens.

Axis: The user-provided axis value (in degrees, between 0 and 180) is used to recommend the lens parameters. The axis value specifies the orientation of the cylinder power in the lens, which is crucial for the correct positioning of the toric lens to correct astigmatism.

By inputting the cylinder and axis values, the calculator will display the recommended lens parameters for CooperVision toric lenses, including base curve, diameter, sphere, cylinder, and axis.
