If a patient has glaucoma in the eye, there is a possibility of recurrence after laser surgery treatment. Glaucoma is a common and frequent disease in the ophthalmology clinic, and it is also a serious blinding eye disease, and the current treatment for glaucoma mainly includes three aspects: one, drug treatment; two, laser treatment; three, surgery. However, it is important to note that no matter which treatment a glaucoma patient undergoes, they need to be checked regularly because glaucoma can change at any time, which means that glaucoma can come back again. In clinical practice, patients with glaucoma need to have their intraocular pressure checked regularly after laser surgery, and the visual field and optic nerve should be checked.
