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.
