Why 3 Diameters:
Get your practice started with 3 diameters
Studies indicate that standard parameters won't work for everyone.
To ensure the right fit on your patients, you need small and large diameter options.
The Pacific University study indicated that larger and smaller corneas would benefit from a larger or smaller lens diameter that is more HVID appropriate.
To further substantiate the P.U. findings, we conducted our own internal clinical evaluation of HVID and comfort. Utilizing our account base, more than 450 patients were measured and asked to rate the comfort level of their contact lens. Like Pacific University, our findings showed that 25% of patients fall outside standard parameters. In addition, we found that these 25% of patients had comfort issues. 37% of patients with HVID < 11.3 and 53% of patients with HVID > 12.3 reported a level of discomfort with their contact lenses.
