Biofinity Multifocal

By John Dick ABO, FNAO

Biofinity Mulitfocal lenses are designed to address a common refractive error associated with the aging patient: presbyopia. As we age, the ability to view objects at a near point clearly begins to diminish. There are several modalities for addressing this problem including multifocal contacts. Biofinity Multifocal lenses are designed to provide the patient with crisp, clear vision at any focal length — distance near or intermediate. Additionally, these lenses provide the patient with comfort and a way to maintain good ocular health.

Starting at around age 40, the ability of the eye to focus on near objects or doing tasks such as reading become more difficult. This is the result of a deficient accommodative reflex. One third of the ability of the eye to focus resides with the transparent refractive medium of the cornea. The remaining two-thirds may be found in the flexing capabilities of the crystalline lens held in place by a series of suspensory ligaments. This flexing ability is called the accommodative reflex or simply, accommodation.

As we age, the suspensory ligaments called the zonules of Zinn become more rigid inhibiting the ability of the crystalline lens to bring objects clearly into focus. To correct his problem, the eyecare professional may prescribe reading glasses, bifocals, monovision contacts or bifocal contacts. Biofinity Multifocal lenses are designed to address this problem through a unique design of Balanced Progressive Technology.

Utilizing this design process, there is a series of concentric zones in each lens with differing powers. The patient’s dominant eye is assigned to the lens with the most distance prescription. The non-dominant eye is used to correct for the near vision with intermediate zones used in each contact. This results in correction for each focal distance at infinity, intermediate and near as the eyes work together to perceptually present a three-dimensional image.

Coopervision also utilizes a patented technology called Aquaform Comfort Science in the production of Biofinity Multifocal lenses. This process is designed to not only provide comfort to the patient through extended wear of their lenses, but also provides an optimum level of protection against common complications of soft lens wear. Biofinity Multifocal lenses are comprised of the hydrophilic hydrogel polymer, comfilcon A resulting in a water content of 48%. This translates to better comfort to the patient as the lens more easily helps to maintain the fluid environment of the corneal tear film preventing discomfort associated with dry eye syndrome.

Additionally, preservation of the corneal tear film provides a barrier of defense against bacterium, denatured proteins and allergens that may build up and cause compromises in ocular health as well as vision. Biofinity Multifocal lenses also provide a high level of oxygen transmittance to the surface of the cornea (128 Dk/t). This prevents a common complication of extended soft wear lens resulting from oxygen deprivation called corneal. Biofinity Multifocals provide the patient with a comfortable lens that will maintain the integrity of their ocular health while simultaneously providing quality vision at all focal lengths not only improving vision, but wearability.
