Purpose
To compare the differences, correlations, and consistency between InnovEyes Sightmap and comprehensive refractometer in measuring refractive degree before surgery
Setting
Ray tracing guided reflective surgery is a novel technique that relies on the examination data measured by InnovaEyes Sightmap, making the accuracy of InnovEyes Sightmap measurements particularly important.
Methods
18 myopia patients (36 eyes) were collected and their refractive degree was evaluated using a comprehensive refractometer and InnovEyes Sightmap, respectively. The differences in data measured by the two instruments were analyzed using paired t-tests, Pearson correlation analysis was used for correlation, and Bland-Altamn statistical analysis was used for consistency.
Results
The equivalent spherical (SE) measured by the InnovEyes Sightmap and comprehensive refractometer were (-5.69±2.18) D and (-5.33±2.17) D, respectively, with statistically significant differences (t =-4.599, P<0.001). The data measured by the two devices have a significant correlation (r=0.977, P<0.001). More than 90% of the points of the two devices are within the 95% confidence interval reference range, with a consistency interval of (-0.55~1.27) D.
Conclusions
Compared with a comprehensive refractometer, InnovEyes Sightmap measures higher refractive degree. The two inspection devices have high correlation and consistency.
