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.
