Non-Contact IOP Estimation Based on Corneal Stress Birefringence: Experimental and Computational Validation [PDF]
SensorsAccurate intraocular pressure (IOP) assessment is essential for glaucoma diagnosis and follow-up. Conventional contact tonometry (e.g., Goldmann and rebound devices) remains widely used, but its accuracy is affected by operator dependence, alignment ...

The Refraction Indices and Brewster Law in Stressed Isotropic Materials and Cubic Crystals
Crystals, 2021 We study the elasto-optic behavior of stressed cubic crystals (all classes) and isotropic materials (like e.g., glasses). We obtain the explicit dependence of the refraction indices on the stress (either applied or residual), as well as a mild ...
