Biofinity Toric - Parameters and Specs

Biofinity Toric is a silicone hydrogel based contact lens developed by CooperVision. Introduced in March 2009, it features Aquaform Technology and a proprietary Optimized Toric Lens Geometry which provides a constant horizontal thickness across the ballast area for better lens stability and reduced rotation. Biofinity Toric contact lenses are made of Comfilcon A with 48% water and an oxygen transmissibility value of 116 Dk/t.

Highlights and Features

• High oxygen transmissibility for healthier eyes
• Soft and moist lens material minimizes deposits and provides excellent all-day comfort
• Round lens edge for more comfort
• Optimized ballast design for improved alignment with your eye
• Approved for daily wear and extended overnight wear based on your eye doc's instructions
• No internal wetting agent – no surface treatment
• A 30% lower contact angle compared to other lenses (such as Air Optix) increases wettability

Who should consider Biofinity Toric?

• Patients with astigmatism who experience discomfort due to dryness when wearing contact lenses and are looking for outstanding comfort
• People who are looking for breathable monthly lenses for healthy and extended overnight wear
• People that want to sleep with their lenses in
• People who want healthy looking eyes
• People who gave up on wearing contact lenses due to discomfort such as dry and itchy eyes

Where to buy Biofinity Toric

Option 1 - Buying through your Eye Care Professional

Ask your eye care professional for Biofinity Toriccontact lenses. Start with trial lenses first. Your eye care professional will make sure that your prescription is up-to-date and that the technical lens parameters satisfy the requirements of your eyes. There are many different base curves and diameters available - sometimes even within the same product line. So it is important to get a proper fitting done before deciding on a lens. Once it is a go, you can buy or reorder through your eye care practitioner. Don't forget to ask your eye care professional whether CooperVision is running a rebate program.

Option 2 - Buying online

If you already have a valid prescription, buying online is easy and convenient. Plus, you can find great deals and discounts. Optix-now is monitoring the prices of Biofinity Toric from many top contact lens retailers, so you don't have to spend a lot of time finding a great deal.

Wearing Details Wearing Details Your wearing schedule should be determined by your Eye Care Professional. It is important to have regular checkups and it is critical to adhere to the maximum wearing schedule as recommended by your Eye Care Professional as he/she will determine wearing time based upon your physiological eye condition and your response to the lenses.	Daily wear or up to 6 nights or 7 days extended wear
Sphere Powers	+8.00D to -10.00D (in 0.50 steps after +-6.00D)

Axes Axes The Axis indicates the placement of the extra power (cylinder orientation) in a toric lens. The available values are always between 0 and 180 degrees.	from 10° to 180° in 10° steps
Base Curves Base Curves The base curve (BC) - measured in millimeters - is also known as the Back Optic Zone Radius (BOZR). It is measuring the radius of the back surface of the contact lens.	8.7 mm

Lens Design	Aspherical
Wetting Agents Wetting Agents Some contact lenses contain wetting agents to retain moisture. They are either integrated into the lens or added to the packaging solution: PVP - polyvinylpyrrolidone PEG - polyethylene glycol PEOX - poly-2-ethyl-2-oxazoline HPMC - hydroxypropyl methylcellulose PVA - polyvinyl alcohol PC - phosphatidylcholine PO - poloxamer	None

Center Thickness Center Thickness Center Thickness (at -3.00D)	0.08 mm
Oxygen Transmission Oxygen Transmission Oxygen Transmissibility (at -3.00D, center, non-edge-corrected). This value indicates to which degree oxygen may pass through a particular material of a given thickness. It is equal to the oxygen permeability divided by the thickness of the measured sample under specific conditions. The higher the oxygen transmissibility the easier it is for oxygen to flow through to your eye.	116 Dk/t
Modulus Modulus The modulus of a contact lens describes the stiffness of the material. Usually a higher water content lens means a less stiffer lens thus making the handling of the lens trickier.	0.75 MPa

UV Blocking UV Blocking UV-A Blocking covers the range from 316nm to 380nm. UV-B Blocking covers the 280nm to 315nm spectrum. The FDA classifies UV blocking capabilities of contact lenses into two groups. In order to be classified into one of the groups, the UV blocking capabilities must meet the following requirements: Class 1: filters >90% of UVA light filters >99% of UVB light Class 2: filters >50% of UVA light filters >95% of UVB light IMPORTANT NOTE: UV-absorbing contact lenses are not substitutes for protective UV-absorbing eye-wear, such as UV-absorbing goggles or sunglasses, as they do not completely cover the eye and surrounding area. Patients should continue to use UV-absorbing eye-wear as directed.	No
Dynamic Light Absorption Dynamic Light Absorption Known from auto-darkening eyeglasses, this new feature will be available for the first time in 2019 as it will mark the date for the introduction of the world's first contact lens that adapts to changing light conditions. Due to a photochromic additive, contact lenses with this feature can auto-darken based on the amount of light entering the lens.	No
Visibility Tint	Yes (Sofblue®)
Inside-out Mark	No
