低旋设计散光软镜临床配戴结果研究

目的评估低旋（Lo-Torque）设计散光软镜的临床效果。方法103名近视散光自愿者分别配戴A、B镜片各两周。对配戴的临床表现进行客观和主觉评价,采用双盲法。结果①镜片稳定性A镜片旋转范围≤5°为82%,B镜片为52%。②镜片在眼中状态移动度优良者,A镜片为91%,B镜片为95%;中心定位优良者,A镜片为87%,B镜片为77%。③舒适度评价A镜片优良者为85.5%,B镜片为80.2%。结论低旋设计特征的散光软镜更符合人眼的生理特征,可以提高视觉质量,增加配戴舒适度。

A clinical study ofLo-torque designed toric soft contact lens

Objective：To evaluate the impact of the Lo-Torque designed soft toric lenses on the performance of clinical fitting.Methods：103 myopias with astigmatism fitted the A and B lens respectively for 2 weeks, and the evaluation included the subjective and objective examination. The fitting and evaluation is double masked.Results：① Lens stability:A lens rotation≤5° takes 82%,B lens takes 52%.②lens performance：excellence in movement with A lens is 91%,B lens is 95%;excellence in centration with A lens is 87%,B lens is 77%.③confort：excellent with A lens is 85.5%,B lens is 80.2%.Conclusion：Lo-Torique designed soft toric lens is improved better fitting for the toric subjects with better visual acuity and more comfort.
