Toric Soft Lens Fitting Tips
Manufacturing tolerances of soft toric contact lenses are not the same as spectacle lenses. In fact, a soft toric lens with a power of 1.25D cylinder may have a tolerance as high as 8˚. Therefore, it would be prudent to over-refract for the resultant cylinder axis as well as sphere and cylinder power.
    Be careful when refitting a toric patient into a new material such as a silicone hydrogel. The over-refraction may change after the initial refit due to the increased transmissibility and modulus, as well as the tolerances related to the manufacturing process.

Feeling Less Is Worth More
The senofilcon A material of ACUVUE® OASYS™ Brand Contact Lenses with HYDRACLEAR™ Plus balances properties to meet the demands of contact lens wearers in environments where eyes feel tired and dry. Its exceptional wettability is similar to that of traditional mid-water hydrogels. ACUVUE® OASYS™ Brand Contact Lenses are the smoothest silicone hydrogel lenses, with approximately 5 times less friction than PureVision™, and approximately 15 times less friction than Night & Day™. With an average of 11,000 blinks per day, patients will benefit from a smooth lens, and your practice will benefit by offering a lens that increases patient satisfaction.
