Abstract

The invention discloses a traditional Chinese medicine compound eye drop for preventing cataract and a preparation method of the traditional Chinese medicine compound eye drop. The preparation raw materials of the traditional Chinese medicine compound eye drop comprise the following ingredients in parts by weight: 45-60 parts of semen cassiae, 25-40 parts of flos buddlejae, 30-55 parts of herba erigerontis, 20-50 part of nux prinsepiae and 1 part of borneol. The traditional Chinese medicine compound eye drop is prepared by traditional Chinese medicines such as semen cassiae, flos buddlejae, borneol, herba erigerontis, nux prinsepiae and the like, and has the efficacy of removing slight corneal opacity and improving eyesight, and is used for improving and treating blurred vision and senile cataract. The compound eye drop has certain innovativeness in prescription selection and a certain social and economic value. Medicines for treating cataract currently are mainly prifenoxine (pirenoxine sodium) eye drop, and the preparation pharmacopoeia record for preventing cataract in a traditional Chinese medicine field is not available. The traditional Chinese medicine compound eye drop has the advantage of the traditional Chinese medicine prescription, and plays the characteristic of subtle droplet administration. The eye drop prepared by the method changes the history of no special efficacy medicines to treat senile cataract.
