Multifocal lenses may seem challenging to fit, but arming yourself with the proper information can make the task far less taxing.
Biofinity multifocal and Proclear multifocal lenses both feature two distance and near lenses to enable accurate prescription of your patient. To identify their dominant eye, start both eyes with their equivalent distance power values.
Optimal vision at all distances
Biofinity multifocal lenses differ from traditional bifocal lenses by employing two lens designs that work in unison to optimize binocular vision at near, intermediate, and distance. Utilizing Balanced Progressive Technology, both lenses provide smooth transitions between zones for clear vision without distracting lines that other bifocal lenses may present.
CooperVision’s monthly disposable contact lens offers a wide variety of prescription options, from mild to severe. Focusing light at multiple distances, these lenses use Aquaform Technology and Balanced Progressive Technology from CooperVision patented technologies; Aquaform locks in water for moist eyes, while Balanced Progressive includes different zones for near, far, and all-around vision correction.
In the initial cohort, Biofinity Multifocal D and NaturalVue Multifocal N lenses produced distance visual acuities 5-6 letters worse than when corrected with spherical spectacle correction (Biofinity MFCL -0.02 +- 0.096; Biofinity Sphere -0.02 +- 0.09; all P.001). When worn mesopic low contrast conditions they also demonstrated significant decreases in acuity compared to equivalent spectacle correction due to glare (nMFCL -0.04 +- 0.093, nD -0.033 +-0.135; all P.001).
This was likely caused by additional aberrations introduced by two multifocal lens designs; however, no difference in acuity existed between these lenses and standard spherical spectacle correctives lenses for cohort two.
Comfortable fit
Biofinity multifocal lenses provide an enjoyable lens-wearing experience for patients suffering from presbyopia. Their three-zone design provides enhanced distance vision while improving near vision; together, these features deliver sharp, clear, and balanced vision.
Monthly silicone hydrogel contact lenses from CooperVision are exceptionally comfortable to wear. Their Aquaform Technology locks water molecules to their surface for soft yet wettable lenses that are gentle on the eyes. Plus, these rounded edges help reduce irritation caused by friction between the lens and the eyelid.
Biofinity multifocal lenses are also breathable and allow a high level of oxygen into the eye, helping keep the eyes white and healthy. Their natural wettability also prevents protein deposits and dryness from occurring on them.
Biofinity multifocal fitting guides not only offer comfort but also allow patients to record essential details for a personalized fit. Patients can select base curves and diameters, add power, and other specifications that will ensure optimal vision correction levels are attained. By following this guide instead of trying it themselves repeatedly, they can avoid frustrating trial and error and enjoy a more successful fitting experience.
Easy to care for
Biofinity Multifocal offered eye care professionals an efficient fitting process and balanced progressive lens design that makes fitting more patients quickly and effortlessly. This ensures they deliver optimal visual performance to each of their clients.
Use the Biofinity multifocal fitting guide to quickly and reliably determine your patient’s ocular dominance and select their near-power prescription. Dominance typically indicates which eye has more blurry distance vision versus near. Using this method provides more reliable and accurate results than using a phoropter or autorefractor for this process.
These monthly contact lenses are specifically tailored to address presbyopia, an age-related condition in which nearby objects become blurry as we age. Utilizing Balanced Progressive Technology, the contact lens delivers impressive vision performance at near, intermediate, and far distances, while the Aquaform Comfort Science lens material offers comfortable wear all day and night long.
Biofinity multifocal lenses allow the eye to comfortably adapt to their lens and focus appropriately at all distances, reducing surface wetting agents that cause discomfort with contact lens use. Furthermore, Biofinity multifocal lenses may be worn continuously for six days and seven nights, making them an excellent solution for managing presbyopia.
Easy to fit
In most instances, making simple adjustments to a lens’s fitting guide will suffice in rectifying its appropriate problem and allow your patient to find comfort with their vision again without extra effort or refractive adjustments. Keep in mind that different brands have differing parameters; slight modifications could make a big difference. Therefore, keeping a cheat sheet with up-to-date fitting guides handy can save valuable chair time when making necessary changes and adjustments.
Biofinity multifocal lenses feature comprehensive edging designs to minimize lens rotation and maximize comfort, along with being constructed of highly breathable silicone hydrogel material for enhanced breathability and optimal vision. These features make these lenses particularly beneficial for patients suffering from dry eyes or who wear their contacts frequently.
An intuitive, fitting philosophy combined with balanced progressive technology produces a comfortable and adaptable lens for patients suffering from presbyopia. Its center-near design allows both eyes to work in unison to deliver a seamless transition between near and distance vision.
Additionally, its optimized rounded-edge design helps reduce conjunctival interaction and lower the risk of dry eye symptoms. Aquaform Comfort Science lens material ensures breathable comfort throughout the day, with various power options to suit different lifestyle needs.
