Abstract

Aim: This study aims to compare accommodative functions between the dominant and non dominant eyes.
Materials and Methods: A comparative study done in 50 healthy subjects include both males and females with age group ranging between (18 -25 years). It was a hospital-based study conducted in the outpatient department of Ophthalmology. The comparison of accommodative function between dominant and non-dominant eyes is measured to determine which eye shows a higher level of accommodative function. This study has been approved by IRB committee, before beginning this study informed consent has been given and the procedure has been explained clearly, 50 Young emmetropic adults were included. All participants were subjected to comprehensive ophthalmic examination including vision, refraction, Intraocular pressure measurements, slit-lamp examination, the dominance of eye is determined using the hole in the card method and Accommodative functions like the Monocular estimated method (MEM), Near the point of accommodation (NPA) and Accommodative facility (AF) done to find out the ocular dominance.
Result: This study shows a higher level of accommodative function in all aspects of accommodative factor such as Monocular estimated method (MEM), near the point of accommodation (NPA) and accommodative facility in the dominant eye. The Mean and Standard deviation value shows a significant difference in all parameters in the dominant eye with a t-value of 7.055(p=.000) when comparing with the Non dominant eye.
Conclusion: Comparing the accommodative function between the Dominant and Non dominant eye we concluded that the Near Point of accommodation and accommodation facility were observed more in the dominant eye as compared with the non dominant eyes. The mean accommodative lead was found to be greater than the normal individual (dominant eye). Hence, it is concluded that the dominant eye has a better accommodative function than the non dominant eye.
