When to fit a small diameter lens

First time wearers

Every practice has patients that can’t master insertion and removal of their lenses – especially first time wearers. The smaller size can be easier to handle for these patients. For kids, it helps alleviate morning struggles with putting contact lenses on. Happy kids, happy parents. 

Patients also have more confidence putting the smaller size in their eye.  If a patient can learn how to insert and remove their lenses more efficiently in their early stages of wear, it will increase their chances of long-term compliance.  

Pediatrics

Like other things we wear, the best comfort is a combination of the right material and the right fit.  Extreme H2O 13.6 is made with ultra-hydrating materials that retain up to 99% of their water throughout the entire wearing period – no matter how extreme the environment. This material combined with the right size lens makes for an outstanding wearing experience.  Known as the gold standard for contact lens comfort – Extreme H2O 13.6 should be the lens of choice for your pediatric patients.

Small corneas and tight lids

Most contact lenses come in a standard 14.2 mm diameter, but this is not the right size for everyone – especially patients with small corneas and tight lids. For them, a smaller 13.6 mm lens will result in a better fit and improved comfort. If you’re not sure about your patients’ cornea size, measure their HVID. Anyone with an HVID of 11.3 or less should be fit in Extreme H2O 13.6.
