This condition is usually caused by corneal epithelial damage caused by strong light irritation of electric welding, causing eye discomfort, with common symptoms such as pain, inability to open the eyes, tearing, blurred vision, etc. The diagnosis can be clarified by slit lamp examination. Ophthalmic numbing medication can be given to relieve pain, followed by anti-inflammatory eye drops and eye drops to promote corneal epithelial growth. Anti-inflammatory eye drops commonly include tobramycin eye drops, pranoprofen eye drops, and erythromycin eye ointment. Drugs that promote corneal epithelial growth include recombinant bovine basic fibroblast growth factor eye drops, also known by the trade name Befosol, or calf blood deprotein eye gel, which can promote corneal epithelial recovery. If the symptoms are not severe, the discomfort will be significantly reduced after 24 hours.
