It would be useful for optometrists to stay up to date on novel innovations in CL materials and designs when prescribing, to avoid or solve a number of common patient problems. Over the last decade, CL manufacturers have provided a variety of scleral contact lens (ScCL) designs that have a wide range of applications. Method: Retrospective analysis on approximately 40 participants (Px) each in 5 trials. Dr. Srinivasan is an optometrist at the Centre for Contact Lens Research (CCLR), School of Optometry and Vision Science, at the University of Waterloo, Ontario, Canada. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. [8], Solution induced corneal staining (SICS) has been shown to vary with different lens types and solutions. CooperVision Insight Newsletter. 2 However, even with the availability of silicone hydrogel materials, one of the biggest clinical challenges is maintaining comfort throughout the wearing day, 3 which is important because .

Solution toxicity in soft contact lens daily wear is associated with corneal inflammation. The SynergEyes VS (Menicon) scleral lens completely vaults the cornea and limbus, landing entirely on the sclera.38 Its toric periphery may be precisely controlled in both the flat and steep meridians, aligning with the scleral for ease of landing and stability.38 This non-rotationally symmetrical lens design incorporates linear landing zones and landing zones with bi-tangential toricity.38 The linear landing zones are designed to follow the linear (rather than curved) shape of the sclera, accommodating a toric sclera.38 This should distribute the lens pressure more equally over the sclera due to the adjustable angles of the flat or steep meridians.38 The company hopes this will improve the scleral lens fit with less risk of air bubble formation or blanching of the conjunctival scleral vessels.38 The toric landing zones can greatly improve vision in patients with residual astigmatism as they are designed to provide consistent stabilization allowing for a front-surface cylinder.

For instance, Air Optix plus with HydraGlyde (Alcon) incorporates two technologiesSmartShield Technology and HydraGlyde Moisture Matrixwhich provide a combination of deposit protection and longer-lasting lens surface moisture.29 According to the manufacturer, lenses with SmartShield technology prevent silicone from reaching the surface of the CLs, which helps the lens surface retain moisture and resist deposition with the intention of maintaining comfort throughout the wearing period.
