Patient: My mother has a cataract in her left eye and is now basically blind. She wants to have cataract surgery and went to the hospital for an examination and the doctor said that the vitreous body is a little cloudy. Wang Wenzhan, Ophthalmology Department of the First Affiliated Hospital of Zhengzhou University: If it is only senile vitreous degeneration turbidity, the degree is generally mild and has little effect on the effect of cataract surgery. Vitreous turbidity due to fundus hemorrhage or trauma requires combined vitreous surgery to restore vision.
