Summary
Finite element analysis models corneal biomechanics for improved efficiency and accuracy. The validated model accurately simulates Goldmann applanation tonometry, aiding in understanding corneal deformation.
Area of Science:
- Biomedical Engineering
- Ophthalmology
- Computational Mechanics
Background:
- Corneal biomechanics are crucial for understanding intraocular pressure and ocular diseases.
- Accurate numerical models are needed to simulate corneal behavior under various conditions.
Purpose of the Study:
