The Contex OK®-EX design is the result of years of research and development. With the advent of myopia control and the desire to quickly reduce larger amounts of myopia, Contex set out to create a lens that would offer the advantages of a controlled tear layer in the reverse zone and the ability to reduce higher amounts of myopia quicker and with more control.
• Optimum Control and Results for High Myopia
• Hyperbolic Treatment Zones for Maximum Flattening
• Dual Aspheric Reverse and Alignment Zones for Improved Lens Centering
• Topographical / Empirical / Inventory / Diagnostic
• Multi-Axis Toric / Astigmatism Option
For years the standard optic zone for orthokeratology lenses has been 6.0mm. The OK®-EX uses a variable optic zone diameter that is calculated to provide a consistent tear film depth at the edge of the optic zone. The higher the target power, the smaller the optic zone becomes. Hyper-Aspheric treatment zones create the ultimate flattening power. The OK®-EX also features double aspheric reverse and alignment zones that help center the lens on even the most difficult corneas.
