摘要
目的 :评估低旋 (Lo Torque)设计散光软镜的临床效果。方法 :10 3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 5 2 %。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。
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.
