Post-cataract surgery glare may be related to corneal injury, inflammation exudation, improper choice of IOL, etc. It can be treated by using nutritive corneal drugs, anti-inflammatory drugs, and choosing aspheric IOL. 1. Corneal injury: cataract surgery usually chooses incision in the cornea, which may cause corneal injury. The refractive index of the injured area is different from the surrounding area, and light may be scattered, resulting in postoperative glare. It can be treated by using nutritive corneal drugs, such as recombinant human epidermal growth factor eye drops and recombinant bovine basic fibroblast growth factor eye drops. 2. Inflammatory exudate: Early after cataract surgery, an inflammatory reaction can usually occur. Inflammatory exudate can also lead to light scattering, which leads to postoperative glare. It can be treated by using anti-inflammatory drugs, such as Pralofen eye drops and Tobramycin Dexamethasone eye drops. 3. Improper choice of IOL: If cataract patients choose spherical IOL, due to the large difference between the peripheral optical area of its center optical area, glare phenomenon is easy to appear after surgery. It is recommended to choose aspheric IOL, which can reduce the postoperative glare. Patients are advised to go to the hospital in time, and specific medications need to be used under the guidance of the doctor.
