Based on the typikon of the Imperial Monastery of the Pantocrator of Constantinople (12th century) and the manuscripts used in the Byzantine hospitals as well as the published Lives of the Saints and other related sources, it is undeniable that special ophthalmological departments existed in the xenones of Byzantium. It is also proven, that specific ophthalmological therapy was practised here including surgery and particularly in the cataract operation. This last operation is attested to, not only by the medical writings of Byzantine writers but also from the therapies of the physician-saints Cosmas and Damian.
根据君士坦丁堡全能者帝国修道院的规则（12世纪）以及拜占庭医院使用的手稿，还有已出版的圣徒生平及其他相关资料，不可否认的是，拜占庭的客店里存在特殊的眼科科室。同样得到证实的是，这里实行了特定的眼科治疗方法，包括外科手术，尤其是白内障手术。这最后一种手术不仅得到拜占庭作家医学著作的证实，也得到医生圣徒科斯马斯和达米安治疗方法的证实。
