    Orthokeratology is an overnight vision correction that provides a good daytime vision without needing any eye correction, that uses unique design gas permeable GP contact lenses to reshape the curvature of the cornea and reduce the refractive errors Objective To evaluate the efficiency of Orthokeratology (Ortho-K) in adolescent with moderate to high combined myopia astigmatism Hypothesis HO: (Ortho-k) lens is an effective way that can be used in high to moderate combined myopic astigmatism correction in adolescents. H1: Orthokeratology lens can't be used as a treatment for adolescents who have high to moderate combined myopic astigmatism. Methods pre and post intervention control study in , using (patients aged between (18 to 25) years , how have moderate to high myopia with low to moderate astigmatism , the patients were fitted with (Ortho-K) lenses for a period of time after they have visual acuity , refraction , axial length and corneal topography tests. Collecting the data was performed at baseline first, 1 week and 1 month after start wearing the lenses

    Prevalence of Non-strabismic and binocular and symptomatic accommodative dysfunctions IN randomized population of Al-Najah university students

    Introduction: Binocular vision is the way your eyes cooperate when they are working ordinarily. This enables your eyes to cooperate to see one picture, rather than two distinct ones. The purpose of this study was to analyze the prevalence of non-strabismic accommodative and binocular dysfunctions in a population of university students Objectives: 1. To describe accurately the epidemiology and then the amount of risk for these problems. 2.To treat and manage these anomalies. 3. To classify them Method: A cross-sectional study will be conducted with a randomized sample of 175 university students aged between 18 and 25 years. All subjects were given a visual examination were each given a thorough eye examination, including binocular-vision testing, near point of convergence, horizontal phoria measurement by von Graefe, and negative and positive vergence amplitudes with prism bar, to determine any form of accommodative or vergence dysfunctions.in which their symptoms were recorded, as well as performing objective and subjective refractive examinations and accommodative and binocular tests. Conclusion: Non‐strabismic binocular vision anomalies are highly prevalent among university students and the prevalence increases with age. With increasing near visual demands in the higher grades, these anomalies could significantly impact the reading efficiency of children. Thus, it is recommended that screening for anomalies of binocular vision should be integrated into the conventional vision screening protocol.
