OxiMap – visualizing oxygen transmissibility of soft contact lenses
A good oxygen supply for the cornea is crucial particularly when soft contact lenses are worn. If the cornea does not have a sufficient oxygen supply, neovascularization is often the consequence. Long hours of wearing comfort can only be guaranteed if a sufficient oxygen supply is guaranteed.
In addition to the TF-Scan, the OxiMap was developed in collaboration with JENVIS Research at the Jena University of Applied Sciences. More and more soft contact lenses exhibit excellent oxygen transmissibility. In contrast, older contact lens materials are not sufficiently oxygen-transmissible and can thus damage the cornea. With the OxiMap you can clearly visualize the oxygen transmissibility of soft contact lenses. Contact lenses of various materials and of different power can be compared with one another (Diagram 7). The OxiMap adjusts itself individually to the contact lens and contact lens power which have been selected. Using this visualization, one can provide the patient with a color representation of how various contact lenses differ in terms of oxygen transmissibility.
