Abstract

This study aimed to acknowledge the link between spherical refractive error and cylindrical refractive error, which is crucial for diagnosing and managing visual abnormalities productively. This research employed a multi-center, cross-sectional, analytical, and retrospective approach to investigate refractive errors. The objective results were refined subjectively to the best visual acuity with conventional clinical representations of refraction using the sphere, cylinder, and axis. The gathered data underwent analysis utilizing statistical software packages such as SPSS and Minitab. The data were abridged as mean, standard error, and 95% CI of the population mean. The link was determined with the box-plot function of the graph, Pairwise Pearson Correlations, and a comparison of the 95% CI of the population mean for the Spherical Refractive Error and Cylindrical Refractive Error. Line plot graphs were utilized to quantify the ratios of With-the-rule (WTR) astigmatism, Against-the-rule (ATR) astigmatism, and Oblique astigmatism (OA). The degree of astigmatism was highest in individuals with spherical refractive error between -0.12 D to -2.87 D (Low Myopia) and between +3.12 D to +5.00 D (Moderate Hyperopia). Mean cylindrical valuation was -0.69±0.05 in Low Myopia and -1.86±0.41 D in Moderate Hyperopia. The proportion of WTR astigmatism decreased in (47–54) year age group, whereas the distributions of ATR astigmatism increased in the (39–46) year of age groups. Correlation between Spherical Refractive Error & Cylindrical Refractive Error was r=0.018, p=0.613. Except for low myopia and moderate hyperopia, the spherical refractive component appears to be autonomous of the cylindrical refractive integrant. Refractive spherical and cylindrical correlations are not as brawny as those between the other eyes
