The K-Max™ is designed to be easy to fit and easy to wear, with very little adaptation time needed.


The K-Max™ is a large diameter, full corneal GP lens.  The large diameter design is intended to offer the patient improved comfort with minimized lid awareness while maximizing oxygen to the cornea.  The lens is designed to provide reduced movement and increased tear exchange.  The anterior surface offers a large optical zone corrected for spherical aberration created to enhance visual acuity.
