白内障摘除术是眼科常见手术，该手术术前需要充分散大瞳孔，并能够于术中保持足够大的瞳孔状态，以利于白内障的摘除。以往多使用阿托品眼液、眼膏或新福林眼液等散瞳剂。自１９９３年以来，我们医院眼科使用日本产０５％Ｍｙｄｒｉｎ－Ｐ散瞳点眼剂，对白内障摘除手术患者进行术前散瞳，收到较好的效果，是一种理想的白内障术前散瞳点眼剂。它既有松弛瞳孔括约肌的作用，又有兴奋瞳孔开大肌的功能，可以充分开大瞳孔，同时，它又是一种短效散瞳剂，不会象使用阿托品眼液那样，瞳孔长时间处于散大状态，不利于人工晶体植入后的缩瞳及瞳孔活动。临床应用证明：０５％Ｍｙｄｒｉｎ－Ｐ散瞳点眼剂具有疗效快，散瞳作用可靠，使用方便易行且无明显副作用等特点，是眼科白内障摘除术前散瞳的理想药物。
