Size Matters when fitting contact lenses
Did you know that most disposable contact lens manufacturers determine the base curve and diameter of their lenses based on the average HVID of 11.8. The unfortunate reality is that 27% – more than one in every four patients you see – have an HVID that falls outside the normal range of 11.3 to 12.3 mm. Putting these patients in an average size lens is not going to provide them with the contact lens comfort they want. This may also contribute to the steady drop out rate we have seen over the past 25 years.
Don’t settle for a one size fit’s all contact lens. Extreme H2O is available in a small and large diameter enabling you to give 100% of your patients the contact lens comfort and vision they expect.
