Abstract
Purpose: The present study aimed to assess the effect of refractive error (RE) correction on stereopsis.
Materials and Methods: A total of 62 participants underwent comprehensive ophthalmic examinations, which included measurements of visual acuity, RE, stereopsis, ocular alignment, as well as examinations of the anterior and posterior ocular segments. Stereopsis was evaluated using the TNO random dot stereogram booklet at a distance of 33cm, both with and without RE correction. The results were then compared to evaluate the impact of RE correction on stereopsis.
Results: Our findings revealed that correcting one diopter of the spherical and spherical equivalent components of RE led to a significant improvement in stereopsis, with improvements of 30.884 and 30.373 seconds of arc, respectively (P = 0.001). However, the correction of other components of RE did not demonstrate a statistically significant effect on improving stereopsis. Additionally, we found no significant correlation between different types and severities of refractive errors and stereopsis.
Conclusion: Correcting the spherical and spherical equivalent components of refractive error may enhance stereopsis across various types of refractive errors.
