There is no conflict between having myopia surgery and having bifocal surgery. Myopia surgery is mainly divided into laser corrective surgery of the cornea as well as crystal implant surgery of the cornea. Corrective laser surgery uses a laser to cut the cornea to correct myopia, and it is performed at the corneal level. IOL implantation surgery is an intraocular surgery in which an artificial lens is implanted into the eye to correct myopia. An incision of about 2-3mm is made in the cornea and the lens is then implanted. Double eyelid surgery is an external eye surgery in which a cut is made on the eyelid to achieve the purpose of heavy eyelid and double eyelid. You can usually consider double eyelid surgery when you are more stable after laser surgery, i.e. about 1 month, and when the situation is more stable after 1 month of crystal implantation. This is because performing the surgery at this time will not cause post-laser or post-crystal implantation infection and will be safer, but theoretically the two do not affect each other.
