Biomedics

Availability

Biomedics lenses by Coopervision are available in a wide range of parameters to assist the patient who may suffer from a high amount of correction. These lenses are aspherical in nature meaning they assist the patient to find a sharp, clear center with little interference from spherical aberration which will limit a patient’s field of view and optical clarity. This design allows light to focus more precisely at a common point seated in front of the visual axis; the pathway light must travel to allow the process of vision to occur. This results in much sharper vision and allows the edges of the contact to remain relatively thin providing comfort to the patient despite the amount of prescription required to corrective their particular refractive error. The lenses are designed not only to accommodate those with high degrees of myopia or hyperopia, but also the astigmatic patient.

Comfort

Biomedics are a hydrogel lens, omafilcon A, used as a substrate in addition to the highly biocompatible phosphorylcholine. Phosphorylcholine attracts and binds water to the lens due to its hydrophilic (water-loving) properties. It has other applications in the medical field, but these characteristics make it highly desirable for use in contact lens manufacturing. Maintaining the fluid environment of the cornea, resisting allergen and bacteria and allowing a high level of oxygen to permeate the contact will assist the patient in maintaining healthy corneas. Additionally, these lenses are designed to resist the build-up of denatured protein chains responsible for potentially warping the cornea and causing poor visual acuities.
