Ophthonix wins patent for custom lens system

San Diego-Ophthonix Inc. has been awarded a patent for the measurement of wavefront deviations to help create customized eyeglasses and contact lenses, its fourth patent this year.

The company said the patents would allow it to create its iZon wavefront-guided lenses as a non-surgical approach to custom vision enhancement. Its Z-View aberrometer can measure the traditional sphere, cylinder, and axis, and compensate for third through sixth high-order aberrations including coma, trefoil, spherical aberration, tetrafoil, distortion, and increasing levels of astigmatism, according to the company.

Designed for the dispensing practitioner, the aberrometer provides an instant display comparing the patient's fully optimized vision with conventional correction. It was launched during Vision Expo West in September.
