Why is eye fatigue easy after myopic operation

Myopia is a common disease in ophthalmology, which can cause patients to show vision decline, which can be corrected by surgical treatment, but some patients are prone to show symptoms of eye fatigue after myopia surgery, mainly due to the following reasons. First, myopia correction surgery will cut off part of the corneal sensory nerve fibers, resulting in reduced reflective tear secretion of the eye, which will cause patients to show eye fatigue and dryness after long-term use of the eye. It can be treated with artificial tear drops to relieve symptoms. Second, after myopia correction surgery, the eyes may show mild hyperopia, such as hyperopia within 50 degrees. When looking at nearby objects for a long time, the ciliary muscles inside the eyeball will use more adjustment force, thus showing symptoms of eye fatigue.
