Ocular thermography in contact lens wearers

Abstract

AbstractThe infra‐red thermal images have been used in the past for measuring the ocular surface temperature, its main advantage being the non‐invasive means. It is well‐known for its ability to detect the pathological and physiological changes in the eye.There are a few studies about ocular surface temperature and contact lenses. Some authors found that insignificant changes in ocular surface. temperature in soft contact lenses did occur, but other authors described that the pre‐lens tear film in soft lens wearers is cooler than that of the non‐CL‐wearing eye, while the temperature of the post‐lens tear film beneath the CL is higher. Regarding hard and gas permeable corneal contact lenses, the changes are between 0.5–1.5°C compared to the naked eyes. However, gas permeable scleral contact lens seems not to modify the ocular surface temperature despite the presence of the tear film stagnation under the lens.This presentation will navigate in the scientific literature about the usability and applicability of ocular thermography in contact lens wearers.
