DCT lens

Development of a specialised contact lens with a built in pressure sensor for continuous determination of intraocular pressure.

DCT-Lens

Background

Glaucoma represents the most common cause for blindness in the western world This eye condition is often associated with increased intraocular pressure. This may fluctuate considerably, particularly in patients with glaucoma. Its continuous measurement may therefore have an important diagnostic impact.

Result

The Institute of Optometry developed the contact lens geometry, enabling the physical intraocular pressure measurement and taking into account physiological compatibility with the eye.
