圆锥角膜患者使用Rose K2软性角膜接触镜的临床表现

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依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依0.37 (0.15 ~1.3),0.42依0.32 (0~1.3) 和0.18依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依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.

Clinical performance of Rose K2 soft contact lens for keratoconus

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.
