马医生给我们讲了一些关于眼部问题的情况。超过10亿人患有不同种类的眼部问题，并且这些病例中约90%能够被预防或治愈。然而，很多人没有钱进行医学治疗。
奥比斯是一个帮助他们的慈善机构。它使用其“飞行眼科医院”来帮助贫困地区的患者。在飞机上，志愿医生进行手术。很多患者负担不起去医院的费用，所以奥比斯的医生会去找他们。这架飞机也被用作一个培训中心。当地的医生和护士被邀请到飞机上学习眼部手术知识。奥比斯的医生可以教他们新的技能。通过培训他们，奥比斯希望能帮助更多的人。去年，完成了超过5万个眼部护理培训课程。
在马医生的上一次访问期间，150名患者接受了手术。他为能帮助人们重见光明并改善他们的生活而感到自豪。他认为现代医学发展迅速，现在很多眼部问题和疾病都能得到治疗和治愈。但他们需要资金来继续开展工作。他们希望更多的人能支持他们。
