In June 2016, CooperVision announced the expanded availability of Biofinity XR toric, a monthly SiHy CL. 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. They have a modulus of 0.6MPa and a Dk/t of 90. Some Silicone hydrogel (SiHy) materials even hope to address patient-related issues, such as digital eyestrain. In March 2016, Art Optical announced the availability of its new 16.5mm scleral lens, Ampleye. Scleral Lenses: SynergEyes VS. Synergeyes.

All rights reserved. Clinician and researcher, Dr. Loretta Szczotka-Flynn summarizes her study comparing corneal physiological responses to traditional Etafilcon A hydrogel material with two common silicone hydrogel materials. [10]. Etafilcon A attracts the highest amount (approximately 1300 g/lens) [ 41, 50] while all other HEMA-based lenses deposit typically less than 100 g/lens lysozyme. According to the company, this comfilcon A-based lens has two novel elements: digital zone optics, which integrates multiple, front-surface, aspheric curves across the entire optical zone, distributing power evenly and simulating more positive power in the center of the lens; and aquaform technology, which has high oxygen transmissibility and low modulus, attracting and binding water. The Rose K2 Soft design features an aspheric back optic zone, front surface toricity and front surface aberration control. Rose K lenses are a frequently prescribed lens design for the correction of keratoconus and irregular cornea conditions and are mostly rigid gas permeable lenses. The most common types of contact lenses are hydrogel and silicone hydrogel these are known as soft contact lenses. Skotnitsky CC, Sweeney DF, Naduvilath TJ, Sankaridurg PR.

An official website of the United States government. In 2016, Johnson & Johnson Vision announced a monthly replacement SiHy lens, Acuvue Vita (senofilcon C). This new material used silicone in a contact lens to allow more oxygen to flow to the cornea, increasing the comfort and clinical performance over hydrogel lenses. Several papers in the peer-reviewed literature have demonstrated that contact lens wearers of omafilcon A typically experience less symptoms and signs of lens-related discomfort vs. wearers of other hydrogel materials, while others have not.

Purpose: NCI CPTC Antibody Characterization Program. When the water in hydrogel lenses gradually evaporates, for example, after many hours of wear or in dry or windy air, the material becomes drier and less comfortable to wear. MeSH [2] The American Optometric Association published a contact lens comparison chart called Advantages and Disadvantages of Various Types of Contact Lenses on the differences between them. 7. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. Corneal Regeneration After Photorefractive Keratectomy: A Review. Cornea. 1. Due to their improved comfort and ease of use, hydrogel lenses have made disposable contacts the first choice for both eye doctors and their patients. To compare subjective, objective and safety performance of silicone hydrogel (SiHy) daily disposable (DD) with hydrogel (Hy) DD contact lenses. Recent research shows a 32% to 42% reduction in myopia using orthokeratology (OK) lenses.39-41 Research also finds partial correction using OK lenses is effective, with high myopes of 6.00D or more partially treated by -4.00D, showing a 76% reduction in myopia progression over one year when compared with spectacle wear.42 Children fitted with a dual-focus multifocal OK lens design in one eye and a conventional OK lens in the fellow eye showed short-term changes to the eye in the multifocal OK lens wearing eyes.43, Concentric and aspheric multifocal designs can slow myopia progression.44 Concentric bifocal lenses, which have a center distance design surrounded by concentric zones of near and distance powers, reduce myopia progression and axial length in children with esophoric fixation disparities, according to investigators.44 Aspheric designs also show reduced myopia progression.45 Use of a center-distance aspheric multifocal design can reduce myopic progression by 50% and axial length by 29% when compared with a single vision wearing group.46, Dual-focus designs and peripheral plus powered aspheric designs also show myopia reduction; however, debate about the visual quality reduction caused by the induction of positive spherical aberration when using this approach persists.47-50.
