If cataract patients cannot return to normal vision after surgery, they should be further examined to see if there are factors affecting their vision, such as fundus lesions, and to rule out postoperative reactions. Cataract surgery is mainly to solve the patient’s refractive interstitial clouding on vision, but if because of the existence of retinal disease, optic nerve disease, etc., can not be solved by cataract surgery at one time. Therefore, if some patients still have blurred vision after cataract surgery, they need to be further examined to find out whether they are affected by retinal diseases or optic nerve diseases, etc. After the diagnosis is clear, laser treatment and further treatment with hormonal drugs such as prednisone can be taken to restore their vision. In addition, there are some patients in the early stage of cataract surgery because of the existence of postoperative reactions, corneal edema and other conditions lead to vision can not return to normal in a short period of time, need to be used through the use of anti-inflammatory drugs, such as prednisolone acetate eye drops, and nutritive corneal medication, such as recombinant human epidermal growth factor drops and other drugs, to promote the recovery of its treatment. There may be other reasons for cataract surgery not returning to normal, and the cause and treatment should be identified under the guidance of a doctor.
