After cataract surgery, if patients experience dryness and other eye discomfort, patients can use vitamin A palmitate ophthalmic gel as prescribed by their doctor to relieve eye discomfort. The creation of a clear corneal incision during cataract surgery can affect the stability of the tear film, causing patients to experience dryness and other eye discomfort after surgery. Vitamin A Palmitate Ophthalmic Gel can treat dry eye, relieve patients of dry, sore eyes and other discomfort, and can also promote corneal epithelial repair. Cataract is a visual disorder caused by clouding of the lens, which occurs as a result of protein degeneration in the lens due to various reasons, resulting in varying degrees of vision loss. Cataract surgery improves vision by clearing the cloudy lens and implanting a clear IOL. It is recommended that patients after cataract surgery follow the doctor’s instructions, have regular checkups, and consult the doctor when discomfort occurs.
