The article summarizes the results of long-term clinical and experimental studies on biomechanical properties of corneoscleral shell performed over the last few years in the Research Institute of Eye Diseases of the Russian Academy of Medical Sciences. A total of 2432 patients (4775 eyes) were assessed. Dynamic bidirectional pneumatic corneal applanation, dynamic pneumatic corneal impression, and elastotonometry were used for in vivo evaluation. A new method of biomechanical assessment - luminescent polariscopy - was studied experimentally. The findings allow correct judgment on biomechanical properties of fibrous tunic in norm and pathology, such as ectatic cornea, glaucoma or previous refractive surgery.
