![]() ![]() Infuse has osmoprotectants, electrolytes, and moisturizers that are released during wear to help maintain homeostasis. The motto for this lens might as well be, “Do no harm.” This is threatened with the presence of a contact lens. The goal of the ocular surface is to maintain homeostasis. This is an enormous accomplishment for me! At removal, my vision was better with the contact lenses in versus out. I was able to wear this lens comfortably for the entire day. I tried this first on myself, because, as a previous high myope and post laser-assisted in-situ keratomileusis (LASIK) patient, I had problems with dryness, clarity, and stability of vision when wearing contact lenses over my extra-flat corneas. While I don’t usually write about lenses or new technology until I have trialed with at least dozens of patients, I am compelled to proceed due to the overwhelming patient need and amazing potential at hand. While Infuse is B+L’s latest entry into the marketplace, as of writing this, it is not yet available in offices. Recently, I was introduced to Bausch & Lomb’s new daily disposable, premium, silicone hydrogel lens, Infuse. Some patients are sentenced to spectacle correction only. However, as anything else, silicone hydrogel daily disposable lenses don’t work for every patient. Many patients are unable to tolerate any other lens. My personal go-to lens for dry eye patients is Dailies Total 1. The leading silicone hydrogel daily disposable lenses are Dailies Total 1 (Alcon) and Acuvue Oasys 1-Day (Johnson & Johnson Vision). Furthermore, while silicone gives us the highest oxygen permeability, it is an innately hydrophobic material. 4Īs ODs know, inflammation is often the root cause of dry eye and is also the culprit in escalating the severity of any ocular surface disease. In fact, a variety of inflammatory mediators (including interleukin IL-6, IL-8, and tumor necrosis factor (TNF-α) have been found to be upregulated in the tears of contact lens wearers. 4Įvaporative stress creates inflammation. ![]() Though my sample size was small, findings do make sense when considering the effect of corneal desensitization and should get ODs thinking.īoth tear film break-up time (TBUT) and tear volume have been found to be significantly reduced in contact lens wearers. I find patients blink less frequently, have a higher incidence of partial blinks, and a slightly lower lipid layer thickness when wearing contact lenses versus when the test was repeated without contact lenses. I have personally compared the blink rate, partial blink occurrence, and lipid layer thickness with and without contact lenses in many of my patients using Lipi-View (Johnson & Johnson Vision). 1-3Įvaporation causes poor wettability of the lens which leads to discomfort, but also deposition, further dehydration, and sensitivities. Lens wear, over time, causes destabilization of the tear film and quickens the rate of tear film evaporation. Upon application, contact lenses split the tear film in half. But for extreme dry eye patients, daily disposables alone, aren’t enough to keep them comfortable or compliant.Ĭontact lenses pose several innate challenges to the ocular surface. My practice’s contact lens orders have been over 90 percent daily disposables for years now. As a dry eye specialist, one of my biggest challenges is keeping my patients in contact lenses. ![]()
