To present success of Toris-K contact lenses in keratoconus and traumatic keratopathy with irregular corneal surface.
Toris-K contact lenses were used to treat 7 eyes of 4 patients with traumatic keratopathy (Case 1) or keratoconus (Case 2, Case 3, and Case 4). All cases had a complete eye examination before the contact lens application. The case with traumatic keratopathy was a 32-year-old male who had corneal penetrating injury due to hobnail strike 23 months ago. The other 3 keratoconus cases were females at the age of 14, 16 and 22 years old. They had high myopia and irregular astigmatism due to keratoconus. All patients refused using rigid gas permeable contact lens because of intolerance. Toris-K contact lenses were fitted on all eyes. All patients were followed-up for 28 months with a complete ophthalmic examination and corneal topography every two months.
Improvement of BCVA of the cases was remarkable. All cases were comfortable with their Toris-K contact lenses for 28 months. There was no significant distortion on the lenses during follow-up period.
Toris-K lenses may be an effective alternative treatment option for the patients with keratoconus and traumatic keratopathy, especially who cannot tolerate rigid gas permeable contact lenses.
介绍托里斯-K型隐形眼镜在圆锥角膜及角膜表面不规则的外伤性角膜病变中的应用成效。
使用托里斯-K型隐形眼镜治疗4例患者的7只眼，其中1例为外伤性角膜病变（病例1），3例为圆锥角膜（病例2、病例3和病例4）。所有病例在佩戴隐形眼镜前均进行了全面的眼部检查。外伤性角膜病变患者为一名32岁男性，23个月前因鞋钉撞击导致角膜穿透伤。其他3例圆锥角膜患者为女性，年龄分别为14岁、16岁和22岁。她们因圆锥角膜患有高度近视和不规则散光。所有患者因不耐受而拒绝使用硬性透气性隐形眼镜。所有眼睛均佩戴了托里斯-K型隐形眼镜。所有患者均接受了28个月的随访，每两个月进行一次全面的眼科检查和角膜地形图检查。
病例的最佳矫正视力（BCVA）有显著改善。所有病例在佩戴托里斯-K型隐形眼镜的28个月期间均感觉舒适。随访期间镜片无明显变形。
对于圆锥角膜和外伤性角膜病变患者，尤其是不能耐受硬性透气性隐形眼镜的患者，托里斯-K型镜片可能是一种有效的替代治疗选择。
