Failed myopia surgery does not necessarily lead to blindness. Surgical failure may manifest itself in the form of visual acuity that does not achieve the desired corrective effect, and it usually leads to blindness when serious complications occur. A detailed series of ophthalmologic examinations, such as visual acuity, corrected visual acuity, intraocular pressure, fundus, corneal topography, central corneal thickness, horizontal corneal diameter, anterior chamber depth, etc., should be performed prior to myopic surgery, and active ocular diseases should be ruled out as well. If abnormalities are present, surgery cannot usually be performed, or serious complications or even blindness may occur. Myopic surgery includes myopic laser surgery and IOL implantation. Common complications after myopic laser surgery include postoperative dry eye, night glare, regression of visual acuity, etc. Blindness is generally rare, while IOL implantation may have complication cataracts, secondary glaucoma, etc., but they are only postoperative complications, non-myopic surgery failures, and will not generally lead to blindness if timely treatment is provided. Myopia surgery is recommended to authoritative medical institutions, after surgery, must follow the doctor’s instructions for regular review, if there is any abnormality, it should be carried out in a timely manner corresponding to the treatment.
