[First Results and Experience with the iTrace Aberometer]

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• Ophthalmic measurements are crucial for refractive and cataract surgery.
• Advancements in aberrometry, keratometry, topography, and pachymetry offer new diagnostic possibilities.
• Evaluating novel devices ensures accuracy and reliability in clinical practice.

Purpose of the Study:

• To assess the data obtained from novel devices for ophthalmic measurements.
• To compare the results of these devices with established methods.
• To determine the clinical utility of these devices in refractive and cataract surgery.

Main Methods:

• The study involved 66 eyes from 33 subjects (22.5 ± 1.2 years).
• Measurements were taken using an auto-refract-keratro-tono-pachymeter (TRK 1P), Keratograph 5M, and iTRACE aberrometer.
• Data were collected over 3 months and statistically analyzed.

Main Results:

• Keratometry values for the corneal anterior surface were comparable across all tested devices.
• Statistically significant correlation was found between objective refraction measurements from TRK and iTRACE (r=0.66, p=0.05).
• Comparable keratometric data and detectable objective refraction and pachymetry values were observed.

Conclusions:

• The evaluated devices demonstrate reliable and valid performance for key eye parameter assessment.
• Significant correlations support the use of these devices in clinical settings.
• These novel devices are suitable for accurate evaluation in refractive and cataract surgery planning.
