because the lens settles and aligns very quickly, usually within one minute, thus reducing chair time and the need for further progress evaluations.” Giroux points to another eye health concern: presbyopia. With Canada’s significant aging population, this is an issue ECPs are facing. “This translates to a rapid decrease in the number of contact-lens wearers and a correspondingly large increase in the number of spectacle wearers. Unsurprisingly, this group of over-40 contact lens wearing patients experiences the largest drop-out rate, mainly due to the fact that their existing contact lenses no longer meet their lifestyle and vision needs.” Giroux says the current marketplace has a limited selection of silicone hydrogel multifocal lenses available to patients. “Clariti 1Day Multifocal is the world’s first daily disposable silicone hydrogel multifocal. As such, it offers presbyopic patients great vision in the healthiest lens material and the safest wearing modality. They can wear a fresh pair of lenses every day, or whenever they choose to wear contact lenses, that will provide natural near, intermediate and distance vision, without the fuss of cleaning and storing their lenses,” Giroux said. Clariti Multifocal offers patients a reusable silicone hydrogel multifocal, combining the features and benefits of Clariti lenses with the groundbreaking Clariti 1Day Multifocal optical design. Mayer notes that while the technology for fitting soft contact lenses has not changed drastically over the years, the technology for measuring the properties of contact lenses has changed. “One of these properties is known as coefficient of friction (CoF),” explains Mayer. “CoF is the ratio of frictional force acting between two surfaces as one of those surfaces moves over the other one - such as the lid blinking over the contact lens surface. A lower coefficient of friction means there is very little resistant for the lid to travel across the lens. New contact lens materials that incorporate lacreaon and hydraclear technologies lower the coefficient of friction providing a more lubricious surface, potentially improving end of day lens comfort for the patient.” According to Leroux, silicone hydrogel has been the most widely prescribed contact lens material largely due to its higher oxygen transmissibility, which contributes to eye health. “One downside of silicone hydrogels is it is a stiffer material than traditional hydrogels and it is hydrophobic, repelling water,” Leroux said. “Clariti lenses solve these problems with a low (0.5 MPa) modulus, high water content (56 per cent) and AquaGen nonsurface treatment technology which makes the lenses hydrophilic, attracting water molecules to the lens surface and providing continuous “wettability.” What hasn’t changed is the vital role of ECP’s in providing patient care and education OPTICAL PRISM | DIGITAL SUPPLEMENT | DECEMBER 2013 11 about contact lens options. Follow-up patient care is the best way for ECPs to guarantee customer satisfaction, building that relationship of trust. “It is up do the ECP how often to schedule regular follow up. However an annual comprehensive eye exam and lens evaluation is recommended for most patients wearing contact lenses,” Mayers said. It comes down to listening to what patients want and helping them make the right choice. “With today’s soft contact lens technology, meeting and exceeding patient needs has never been easier,” Mayers said. “Start the c ??fW'6F???( ??( ??
