Age and other risk factors for corneal infiltrative and inflammatory events in young soft contact lens wearers from the contact lens assessment in youth (CLAY) study. [7] Lower modulus, among other factors, such as lens design and diameter, is likely to decrease the incidence of these events in daily and extended wear, without sacrificing the paramount benefits of increased oxygen. Lens surface, lens corneal alignment, edge profile and quality, interactions with lens solutions are all probable factors to be considered in producing a lens with optimum comfort. contact lens related problems and complications. 2017;32(1):30-5.8.

As both Clariti 1 Day and Clariti Elite are somofilcon A, somofilcon A* is used to refer to Clariti Elite. Mean time to healing was 3.17 days (SD 0.37) in the Comfilcon group, and 3.21 days (SD 0.4) in the Senofilcon group, with no difference in defect size. The SynergEyes VS (Menicon) scleral lens completely vaults the cornea and limbus, landing entirely on the sclera. 2014;97:411-417. The objective of the study is to compare the overall subjective comfort profile over 8 hours of lens wear in two groups of habitual soft contact lens wearers (daily disposable hydrogel lenses and frequent replacement lenses) when refitted in to somofilcon A lenses.

Is using any systemic or topical medications that will affect a study outcome variable, and/or ocular health. National Library of Medicine [9,10] While Biofinity [9] and PremiO [11] lenses perform well in short-term testing, longer term evaluation of Biofinity, PremiO and Avaira is essential as SICS has been associated with a 3-fold increase in low grade corneal inflammation [12] and decreased comfort.
