Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evaluation of the ciliary muscle thickness, area, and anterior chamber angle, as well as anterior sclera thickness in subjects, to investigate the relationship between these measurements and corneal biomechanics. Clarify whether aqueous humor displacement, anterior sclera, and ciliary muscles influence the assessment of in vivo corneal biomechanics.
