The quality of vision obtained through spectacles and toric hydrogel contact lenses is important when determining which correction type is best.
Twenty-six subjects with 0.75D-3.50D of refractive astigmatism were selected to wear Sunsoft Custom toric hydrogel contact lenses. Snellen acuity and contrast sensitivity measurements were gathered with both toric hydrogel lenses and spectacles. At the conclusion of the study each subject completed a questionnaire rating his or her preference for spectacles or toric hydrogel lenses based on the quality of vision with each.
Our findings reveal no statistically significant difference when comparing contrast sensitivity thresholds, Snellen acuity thresholds or subjective preference between spectacles and toric hydrogel lenses.
Based on quality of vision, practitioners should not hesitate to recommend toric hydrogel lenses in addition to the traditional spectacle correction as a viable method of correction for the moderately astigmatic patient.
在确定哪种矫正方式最佳时,通过眼镜和复曲面水凝胶隐形眼镜获得的视觉质量很重要。
选取26名有0.75D - 3.50D屈光性散光的受试者佩戴新视野定制复曲面水凝胶隐形眼镜。使用复曲面水凝胶镜片和眼镜分别测量斯内伦视力和对比敏感度。在研究结束时,每位受试者完成一份问卷,根据每种矫正方式的视觉质量对眼镜或复曲面水凝胶镜片的偏好进行评分。
我们的研究结果显示,在比较眼镜和复曲面水凝胶镜片的对比敏感度阈值、斯内伦视力阈值或主观偏好时,没有统计学上的显著差异。
基于视觉质量,从业者在为中度散光患者进行矫正时,除了传统的眼镜矫正外,应毫不犹豫地推荐复曲面水凝胶镜片作为一种可行的矫正方法。
