Swelling and pain when looking at near objects 1 month after macular tear surgery is usually due to unrelieved intraoperative irritation, elevated intraocular pressure, and improper postoperative rest. 1. As macular tear surgery with fundus laser irradiation is an internal eye surgery, it may cause eye distension within 1 month after surgery due to wound irritation, or eye swelling due to wound infection. 2. Fundus laser irradiation for macular tear surgery may damage the blood vessels in the fundus or form retinal neovascularization, which may lead to vascular leakage, increase intraocular pressure, cause optic nerve damage and other manifestations, and cause swelling and pain in the eyes when looking at near objects. 3. Post-operative stress and poor sleep quality can also lead to eye fatigue and distended vision. If you have pain and swelling after surgery, it is recommended that you go to the hospital to have your eyesight, fundus and intraocular pressure checked in time to find out the cause of the problem and then treat the cause of the problem.
