一年有十余人戴隐形眼镜失明

本报记者刘璇 通讯员金宇欣 杜巍巍

爱俏配了隐形眼镜,又嫌麻烦懒得每天取戴,没想到5个月后右眼隐形眼镜竟然跟角膜长到了一起,角膜被隐形眼镜“咬”出一个绿豆大小的“洞”,彻底失明。幸运的是,经过半个多月的抗感染治疗,女孩保住了另一只眼睛。

记者接连两天从武汉多家医院眼科获悉,门诊中经常碰到因为佩戴隐形眼镜不当造成角膜溃疡甚至失明的患者。专家们一致表示,隐形眼镜尽量少戴,矫正视力最安全有效的方法还是佩戴框架眼镜。

隐形眼镜5个月没取致右眼失明

21岁的程程是新洲人,在青山一家公司打工。3月初,她到眼镜店配了副隐形眼镜。坚持了一个月后,她嫌每天取戴太麻烦,懒得再摘。半个月前她一早起来,发现自己的右眼看不见了,慌忙赶到武汉市普仁医院眼科求诊。

程程告诉接诊的彭建军医生,最近几个月眼睛总是红痒刺痛流泪,买了眼药水点也不见效。检查发现,程程右眼没有视力,左眼视力只有0.5。在裂隙灯下一看,彭建军倒吸了一口凉气:程程双眼黑眼球上覆盖着一层膜样东西,是隐形眼镜和角膜“长”在了一起。角膜充血水肿,中央区大片溃疡,右眼角膜正中的瞳孔位置还破了一个绿豆大小的“洞”。

“不可能啊!我最近都没戴过隐形眼镜。”程程一脸的匪夷所思。当彭建军从她眼睛里取下两枚隐形眼镜后,她呆了。一番苦思冥想后,终于想起那副隐形眼镜是半年前戴上去的,之后就没取下来过。

“由于角膜溃疡中央穿孔,右眼彻底失明了,只能做角膜移植。”说起此事,彭建军一脸痛惜。

隐形眼镜引起的失明每年都有

武汉同济医院眼科教授刘恒明告诉记者,门诊中经常碰到因工作忙、怕麻烦或偷懒,几天不摘取隐形眼镜,导致眼睛发炎感染甚至是镜片取不下来的病人,都是二十几岁的小年轻;因此而失明的,每年总会碰到十多例。

他介绍,角膜90%的氧气都来自空气,戴上隐形镜片后,角膜处于相对封闭的真空缺氧状态,很容易造成角膜缺氧、干涩,甚至发生“霉变”,极易诱发结膜炎、角膜炎、角膜溃疡穿孔甚至失明。眼球表面缺少了泪液的清洗润滑,时间一长,镜片就会与角膜紧紧贴在一起。几乎每个戴隐形眼镜的人,都会感觉眼睛干涩不舒服。

刘恒明提醒,为了降低感染风险,平时除了要注意佩戴卫生外,更应该尽量缩短佩戴时间,平时尽量以框架眼镜为主。如果午睡超过1小时,就应该把隐形眼镜摘取下来;每天戴的时间不要超过6个小时,睡觉时一定要记得取下来。同时注意取戴卫生,每晚用专用眼镜水浸泡清洗。
