Slide 1: Contact Lenses In Silicone Hydrogel – The Vision For The Future? The concept of lenses created from silicone hydrogel was first suggested over 20 years ago. The potential benefits have been clear but the technological problem was since difficult since needing to mix oil as well as water to create an optically clear item. Researcher agencies have to day invested substantial academic as well as financial resources to achieve the high performance gentle lenses these days. They have done this quite simply since they see this fabric as the way forward and the best standard into the future. At the time associated with writing, silicone hydrogel contact lenses are available in the united states from 4 manufacturers: "night & evening " and "O2OPTIX" from CIBA Vision, "real Vision" through Bausch & Lomb, as well as "Acuvue OASYS" and "move forward " from J&J eyesight Care. OXYGEN TRANSPORT So what’s so special concerning silicone hydrogel as a lens material? essentially , the great benefit of this material will be it’s capability to transport air to the vision and thus preserve proper vision health. Modern day contact lens technologies is all related to oxygen permability, which is measured using the "Dk" index. And then for optimal air transmission, this must be up to possible. The Dk of standard , non-silicone dependent hydrogel contact lenses is proportional to the quantity of water how the material holds , since air dissolves to the water-component with the material and so diffuses with the lens. The Dk in fact increases logarithmically with growing water articles. Water alone has a Dk of simply 80, hence placing a ceiling on the Dk of convential materials, and also the original gentle contact lens material , polyHEMA, possesses a Dk of simply around 12 (with a water content of about 38%). However, in silicone hydrogels, the relationship in between Dk as well as water articles is the opposite. Here increased water articles implies lower Dk. Using these lenses Dk increases considerably as the silicone content -- not water content -- of the lens increases. The Dk ideals of silicone hydrogel contacts are much more than those of more mature soft lens materials. SLEEPING connected LENSES According to market information from CIBA Vision, 84% of gentle contact lens wearers occasionally sleep with their contact lenses in, as well as one-third acknowledge to carrying this out regularly. 25% of wearers of one in order to two-week disposable lenses with low air transmissibility from time to time or routinely sleep inside their lenses overnight. And 72% of gentle contact lens wearers said they'd prefer to be allowed to wear their lenses overnight provided it had been safe. Thus the demand for contact lenses with the capablities of silicone hydrogels will be evidently quite high with almost three-quarters associated with soft lens wearers planning to be able to sleep in their contact lenses. LENS HANDLING Silicone hydrogel contact lenses are much more rigid compared to their conventional counterparts, as a result of presence associated with silicone. This increased stiffness does incorporate some advantages, producing the contact lenses markedly easier to handle and so the ideal choice for
Slide 2: wearers using a less fragile touch. There exists a downside to nevertheless in that the rigidity makes the lenses less prone to implementing the shape with the eye thus readily, resulting in the possibility for a few of lowered comfort. REDUCED DEPOSITIONS Historically, the deposition associated with proteins as well as lipids is a problem with contacts. The amount of depositions is essentially linked to the duration of wear and tear , the lens material and also the tear structure of each individual wearer. With traditional contact lenses , a regular replacement routine greatly cuts down on the buildup associated with harmful deposits. Silicone hydrogel contacts have been proven to offer major benefits in the reduction of protein as well as lysozyme deposition. Indeed, with the correct alternative schedule as well as appropriate care system, difficulties associated with protein deposition are becoming almost anything of the past. DRY EYES A difficulty frequently encountered by wearers of standard soft contacts is one of a feeling of discomfort as well as "grittiness" within the eyes on the end of the day. It has been noted that after one week wearing silicone hydrogel contact lenses , the quantity of normal soft lens wearers in a particular research group which previously suffered significantly through end-of-day dry skin , was lowered dramatically to merely 13% with the sample. LIFESTYLE BENEFITS Silicone hydrogel contact lenses also provide some benefits that conventional lenses will not. Continuous wear contact lenses could be particularly very theraputic for use by members associated with certain professions , such as health-related workers, police , the military and firefighters who often work unstable and extended stays. Furthermore, an increasing amounts of contact lens wearers can now take pleasure in active out of doors lifestyles, taking pleasure in pursuits for example camping as well as hiking where it is often challenging to handle and disinfect the contact lenses with the proper level of hygiene. THE FUTURE for CONTACT LENSES There is much evidence in order to suggest that, owing to their considerable benefits more than conventional gentle lenses, silicone hydrogel contact lenses will ultimately, as well as sooner rather than later, displace other types associated with contact lens as the prefferred choice for each daily as well as overnight wear for the majority associated with contact lens wearers. Silicone hydrogel lenses provide a much improved physical efficiency , excellent dealing with properties as well as greater comfort. They might be regarded as the ideal lens for general purpose utilize that exists today and therefore are likely to end up being the new everyday standard. Silicone Hydrogel Contact Lenses
