圆锥角膜患者使用Rose K2软性角膜接触镜的临床表现（英文）

Clinical performance of Rose K2 soft contact lens for keratoconus

目的:评价圆锥角膜患者使用Rose K2软性角膜接触镜的舒适度及视觉表现。方法:横断面研究。50例患者(50眼)接受全面的眼科检查,包括屈光度、裸眼视力(UCVA)、最佳矫正视力(BCVA)、裂隙灯显微镜及眼底检查、泪膜破裂时间(BUT)、角膜地形图和对比敏感度。戴镜后,测量最佳戴镜矫正视力(BCLCVA)、对比敏感度及舒适度通过平均视觉模拟量(VAS)呈现。结果:患者平均年龄为26.2±6.0(16~39)y。使用Rose K2软性角膜接触镜UCVA,BCVA,和BCLCVA的平均logMAR值依次为0.61±0.37(0.15~1.3),0.42±0.32(0~1.3)和0.18±0.20(0~1.3)。使用接触镜后视敏度显著提高(P<0.05),在明视和暗视条件下,对比敏感度数值明显增加(P<0.05)。Rose K2软性角膜接触镜的视觉模拟量(VAS)值为8.02±1.64(5~10)。结论:圆锥角膜患者使用Rose K2软性角膜接触镜能够改善视力,对比敏感度以及舒适度。

AIM： To evaluate the comfort and visual performance of Rose K2 soft contact lenses in patients with keratoconus.METHODS： Fifty eyes of 50 participants were included in this cross-sectional study.Each participant received a full ophthalmologic examination involving refraction,uncorrected visual acuity （UCVA）,best spectacle corrected visual acuity （BCVA）,slit-lamp biomicroscopy-fundoscopy,break-up time （BUT）,corneal topography,and contrast sensitivity.After contact lens was fitted best contact lens corrected visual acuity （BCLCVA）,contrast sensitivity,and comfort rating via visual analogue scales （VAS） were performed.RESULTS： The mean age was 26.2±6.0 （range： 16 to 39）y.The mean logMAR UCVA,BCVA,and BCLCVA with Rose K2 soft （in order） were 0.61±0.37 （range： 0.15-1.3）,0.42±0.32 （range： 0-1.3）,and 0.18±0.20 （range： 0-1.3）.There were significant increases in visual acuities with contact lenses （P 〈 0.05）.The mean contrast sensitivity scores were significantly better with both contact lens in mesopic and photopic conditions （P 〈0.05）.The mean VAS score was 8.02±1.64 （range： 5-10） for Rose K2 soft.CONCLUSION： Rose K2 soft contact lens can improve visual acuity,contrast sensitivity with comfort in patients with keratoconus.
