    Using a programmed calculator with a lensometer improves prescription calculation accuracy and efficiency. This method offers a cost-effective alternative for physicians seeking enhanced lensometry performance without expensive automated equipment.

    Area of Science:

    • Ophthalmology
    • Optometry
    • Medical Device Technology

    Background:

    • Traditional lensometry often involves complex arithmetic, leading to errors and inefficiencies.
    • Prescription calculation is a critical step in lensometry, directly impacting patient care.

    Purpose of the Study:

    • To evaluate the accuracy and efficiency of using a programmed calculator with a lensometer for prescription calculation.
    • To present a cost-effective alternative to fully automatic lensometry devices.

    Main Methods:

    • A programmed calculator was integrated with a standard lensometer.
    • Prescription calculations were performed using the combined device and compared to traditional methods.

    Main Results:

    • The combination of a programmed calculator and lensometer demonstrated increased accuracy in prescription calculations.
