Comparison between vision of high myopic using spectacle and contact lens

Abstract

Aim: This cross-sectional hospital-based study was aimed to compare the vision outcome of subjects with high myopia when wearing spectacle correction and with soft contact lenses. Method: Forty-two subjects (84 eyes) with high myopic error were investigated in the period from May 2017 to March 2018 at University eye hospital, Noor Alhoda Modern Specialist Medical center, Ein Alrowia optical center, Koush optical center, Hob Alwatan Charity Organization at Northern State. The data recorded was: uncorrected vision by Snellen chart and visual acuity with spectacle correction and with soft contact lens. Fundus was examined using direct ophthalmscope. Results: High myopia was present in (38.1%) males and (61.9%) female, mean of age was 27.3±10.8 years. The mean of objective refraction was 9.38±3.8D, spectacle power mean was 7.93±3.15D, contact lens power had mean 7.05±2.40D, Unaided vision showed mean of 0.06±0.07 which improved to 0.64±0.26 with spectacle correction and with contact lens to 0.88±0.28. 45 (53.5%) of patients showed fundus changes. Conclusion: In spite of apprehensiveness of most of people in our community, contact lenses give a significant improvement in vision of high myopic comparing with spectacles.
