Summary
Multispectral refractive tomography shows high repeatability for central and peripheral myopia measurements. Peripheral nasal, temporal, superior, and inferior measurements were less precise than central ones.
Area of Science:
- Ophthalmology
- Optometry
- Optical Engineering
Background:
- Accurate refractive error measurement is crucial for myopia management.
- Evaluating new technologies for precise central and peripheral refraction is an ongoing need.
- Multispectral refractive tomography (MRT) offers a novel approach to objective refraction.
Purpose of the Study:
- To assess the repeatability of a multispectral refractor for central and peripheral myopia.
- To compare MRT measurements with objective refraction (OR) and subjective refraction (SR).
Main Methods:
- Prospective study of 60 myopic patients across three refractive error groups.
- Central and peripheral refraction measured using MRT pre- and post-cycloplegia.
- Intraobserver repeatability analyzed via Sw, TRT, and ICC; agreement assessed using Bland-Altman plots and 95% LoA.
Main Results:
- High intraobserver repeatability (ICC > 0.97) for central and peripheral refraction.
- Peripheral nasal, temporal, superior, and inferior quadrants showed larger error intervals (up to 1.43 D).
- 95% LoA between MRT and OR/SR ranged from -1.39 D to 1.16 D, varying with cycloplegia.
Conclusions:
- Multispectral refractive tomography demonstrates good repeatability for myopia assessment.
- Peripheral refraction measurements in specific quadrants require further refinement.
- The technology shows promise for objective and repeatable refractive error evaluation.
