Air Optix Night and Day Aqua provide a myriad of benefits to patients who fail to observe a regimen of contact lens wear and care recommended by their eyecare professional. These lenses have a patented manufacturing process called TriComfort™ that basically addresses three primary problems extended soft lens wear presents — protein deposits, oxygen transmissibility and comfort. Eyecare professionals generally recommend their patients remove their contacts at day’s end, but patients today are busier than ever with family obligations, work or school. Schedules are no longer from nine to five and contact lens care is typically a low priority if even a consideration. This is why Air Optix Night and Day Aqua are beneficial to the maintaining good ocular health.
Maintaining a healthy cornea requires the proper amount of oxygenation. If deprived of oxygen, the cornea will initiate an autoimmune response in the form of growing new blood vessels that will carry oxygen and nutrients to the affected areas. This ingrowth of new blood vessels is known as corneal neovascularization. The cornea is a transparent medium covering the iris, pupil and anterior chamber of the eye including the visual axis, the pathway light must travel to reach the retina and allow vision to occur. If neovascularization becomes a significant problem, it will disrupt this pathway and not allow light to properly reach the retina resulting in distorted vision. Allow more oxygen to reach the cornea, Air Optix Night and Day Aqua contacts, also provide a more natural feeling to the contact wearer. Objective clinical trials performed by the Food and Drug Administration, led the FDA to approve these contacts for 30 days of continuous wear — day and night. When compared with the predecessor, Ciba Focus Night and Day, and all other contacts approved for 30 day continuous wear, these lenses have a much higher level of oxygen transmissibility at 175 Dk/t.
Excessive protein deposits are another concern when wearing contacts for extended periods greater than traditional planned replacement lenses. They may cause complications that can range from mild to severe. Mild complications include dry eyes and discomfort whereas more problematic damage from protein deposits can lead to allergic reactions, infections and alter the shape of the cornea causing distorted vision. Air Optix Night and Day Aqua contacts have an extremely smooth surface as a result of patented bi-silicone hydrogel technology. This polymer is 45% softer than traditional polymers used in contact lens manufacturing and is often referred to as “liquid skin.” This provides greater comfort and doesn’t allow protein to deposits to adhere as easily to the lens surface.
Retaining the fluid environment of the surface of the cornea, known as the tear film, has always been a balancing act for contact patients and eyecare professionals alike. Given the inherent material properties of Air Optix Night and Day Aqua contacts, patients enjoy greater comfort and less concerned about complications and adherence to a wearing regimen. This provides the eyecare professional and their patients with peace of mind.
