A micro-computer program package for the computation of intraocular lens powers.

Area of Science:

• Ophthalmic optics
• Medical software development
• Biomedical engineering

Background:

• Accurate intraocular lens (IOL) power calculation is crucial for successful cataract surgery.
• Existing methods, like the Binkhorst IOL Power Module on TI-58C calculators, have limitations in data entry accuracy and efficiency.

Purpose of the Study:

• To introduce a micro-computer software package for precise IOL power calculation.
• To enhance the accuracy, speed, and efficiency of IOL power calculations in ophthalmic practices.

Main Methods:

• Development of a micro-computer software package compatible with Z80 computers and the CPM operating system.
• Implementation of established formulas for calculating IOL powers and estimating postoperative refractions.
• Features include data entry validation to prevent clerical errors and patient data storage on disc files.

Main Results:

• The software package provides accurate IOL power calculations and estimated postoperative refractions.
• Data entry is streamlined, minimizing transposition errors and impossible value entries.
• Patient information storage on disc files improves record retrieval efficiency.

Conclusions:

• The designed micro-computer software offers a more accurate, efficient, and legible method for IOL power calculation.
• This software enhances ophthalmic practice by reducing errors and improving workflow.
• It represents an advancement over programmable calculator-based methods for IOL power calculations.
