Using preservative-free artificial tears to relieve dry eye symptoms after cataract surgery
A study of 20 17 in the United States showed that more than half of the elderly with an average age of 70 who underwent cataract surgery had dry eye symptoms during preoperative examination. Fortunately, with the help of preservative-free artificial tears, most symptoms of dry eye can be improved.
