To report the clinical results of the use of the YK contact lens (Lucid Co., Seoul, Korea) for keratoconus.
One hundred and twenty nine keratoconic eyes were fitted with a YK lens which has one base curve and three peripheral curves. A light feather touch fluorescein pattern was obtained based on topographic indices. Visual acuity, comfort, mean wearing time, and ocular tissue changes were evaluated. Mean follow up was 17.5 +/- 13.8 months (range 6-75).
One hundred and twenty six (97.6%) eyes tolerated the contact lenses. A total of 94.5% of the eyes achieved a visual acuity of 20/40 or better (average 0.79 +/- 0.21), and flatter base curve radius (BCR) was related to better visual acuity. One hundred and seventeen (90.7%) eyes reported that the lenses were comfortable. Mean wearing time was 12.1 h per day (range 4-18). Changes in keratometric values were not significant between baseline and final follow-up visit.
The YK lens can provide successful visual outcome, with comfort, and no significant influence on the progression of keratoconus.
报告使用 YK 隐形眼镜（韩国首尔 Lucid 公司）治疗圆锥角膜的临床效果。
129 只圆锥角膜眼使用 YK 隐形眼镜进行矫正，该隐形眼镜有一个基弧和三个周边弧。根据地形图指数获得轻微羽毛状的荧光素图案。评估视力、舒适度、平均佩戴时间和眼部组织变化。平均随访时间为 17.5+/-13.8 个月（范围 6-75 个月）。
126 只（97.6%）眼能够耐受隐形眼镜。共有 94.5%的眼视力达到 20/40 或更好（平均视力为 0.79+/-0.21），并且基弧半径更平坦与更好的视力相关。117 只（90.7%）眼报告隐形眼镜舒适。平均佩戴时间为每天 12.1 小时（范围 4-18 小时）。角膜曲率值在基线和最终随访之间没有显著变化。
YK 隐形眼镜可以提供成功的视觉效果，同时舒适度高，对圆锥角膜的进展没有显著影响。
