Whether a patient with high myopia is suitable for corneal laser surgery or IOL implantation depends on the patient’s eye condition. Generally, patients with higher myopia and thinner corneal stroma are suitable for intraocular IOL implantation. High myopia refers to myopia of more than 600 degrees. For myopia of this degree and above, if you choose corneal laser surgery to correct myopia, the thickness of the corneal stroma, the number of endothelial cells and other aspects of the cornea are more demanding. If the patient’s cornea thickness is thin and unsuitable for corneal laser, intraocular lens implantation is feasible, to correct myopia, and to improve the visual acuity. It is recommended that myopic patients should consult regular hospitals to assess their condition and choose the appropriate surgical method to correct myopia under the advice and guidance of their doctors.
