    Area of Science:

    • Ophthalmology
    • Biomedical Engineering
    • Medical Instrumentation

    Context:

    • Applanation tonometry is a standard method for measuring intraocular pressure (IOP).
    • Modern tonometry techniques face limitations in accuracy and speed.
    • Ocular biomechanics and pressure sensing are critical in glaucoma diagnosis.

    Purpose:

    • To review the capabilities and limitations of modern applanation tonometry.
    • To introduce a novel contactless tonometry method developed in Hungary.
    • To compare this new method with existing techniques like Grolman's.

    Summary:

    • The paper discusses current applanation tonometry, noting its constraints.
    • A new contactless tonometry method utilizes an air jet and electronic system for IOP measurement.
    • This technique allows for the study of rapid events occurring in fractions of a second.

    Impact:

    • The novel contactless tonometry offers enhanced accuracy for IOP assessment.
    • This technology may improve the diagnosis and monitoring of eye conditions like glaucoma.
    • The ability to study rapid ocular events could lead to new insights in ophthalmic research.
