研究目的:

本研究旨在探究角膜塑形镜对间歇性外斜视(-15△<=斜视度<=-35△)合并近视患者的眼位控制及视觉功能的影响,并分析其潜在机制,评估配戴角膜塑形镜的安全性;同时分析角膜塑形镜对IXT(-15△<=斜视度<=-35△)合并近视患者屈光度及眼轴的影响,评估配戴角膜塑形镜的有效性;接着探索镜片偏移与调节功能变化、双眼视觉变化等因素与斜视控制效果的相关性;本研究通过上述分析为合并近视患者的临床治疗决策提供科学依据。  

Objectives of Study:

This study aims to investigate the effects of orthokeratology (OK) lenses on eye position control and visual function in patients with intermittent exotropia (IXT) (-15△<= deviation angle <=-35△) combined with myopia, while analyzing the underlying mechanisms and assessing the safety of wearing OK lenses. Additionally, it evaluates the efficacy of OK lenses in influencing refractive error and axial length progression in myopic IXT patients. Furthermore, the study explores correlations between lens decentration, accommodative function changes, binocular vision alterations, and the effectiveness of exotropia control. Through these analyses, the research seeks to provide a scientific foundation for clinical decision-making in the treatment of patients with coexisting IXT and myopia.
