If infection occurs after cataract surgery, it can lead to loss of vision. Generally speaking, patients can recover gradually after active anti-infection treatment, but the specific recovery is related to the severity of the infection in the patient’s eye. If the infection of the conjunctiva or eyelid does not spread to the inside of the eyeball after surgery, the patient can follow the doctor’s instructions to actively use antibiotic drugs for treatment, after controlling the infection, the general recovery is faster, such as levofloxacin eye drops, tobramycin eye drops and so on. However, if the infection has spread to the inside of the eyeball to form endophthalmitis, it is likely to seriously affect the patient’s vision recovery or even cause blindness, usually need to do vitrectomy surgery in a timely manner as well as the use of antibiotics in the eye irrigation to control the infection, such as vancomycin and so on. However, if the infection is severe, it is usually more difficult to recover and the patient may need to have the eye removed. After cataract surgery, it is recommended that patients follow the doctor’s instructions for care, have regular checkups, and seek prompt medical attention when discomfort occurs.
