Cataract has a long history and was known about 2500 BC in Egypt. In the medieval times, physicians and surgeons used surgical approaches to ease cataract (āb morvārid). Albucasis, as a Great Spanish Muslim surgeon (936-1013 AD) has a detailed and accurate description of cataract surgery procedure and patient care in his manuscript, Al Tasreef. His description can show surgical development to ease cataract in medieval time.
