Abstract: Aim: To assess the phoria associated with myopia before and after refractive correction. Study Design: It was a cross sectional study. Duration and Setting of the Study: The study was conducted from March 2023 till August 2023 at ISRA University Islamabad campus. Methods: University students and staff members with myopia ages 18 and above, were included using a non-probabilitysampling technique. Verbal consent from the study population was obtained, and ethical consideration was obtained from the ethical committee of the Pakistan Institute of Rehabilitation Sciences (PIRS) at ISRA University Islamabad. Data was collected using a self-constructed questionnaire (Performa) with the use of cover test Maddox Rod and Maddox Wing test. Study data was analyzed using the statistical software SPSS 20. Results: Total subjects were 100 in which 54 were female. Before correction, the mean value for total phoria came out to be 1.96 ± 0.84 Prism Diopter and after correction, (the mean value was 1.65 ±0.91 Prism Diopter). Significant differences P<0.01 were seen before and after correction. The study showed that without refractive correction, 52% of participants had exophoria, 30% had orthophoria, 14% had esophoria, 02% had hyperphoria, and 2% had hypophoria. While after myopia refractive correction 61% of subjects had orthophoria, 24% had exophoria, 11% had esophoria, 3% had hyperphoria, and 01% had hypophoria. Conclusion:The study highlight the significance of refractive correction, especially in treating exophoria, as treatment resulted in a notable shift towards orthophoria. When doing evaluations, optometrists and other eye care specialists should take the prevalence of various ocular disorders into account and adjust refractive corrections accordingly.
