High myopia is not a contraindication to TFA. If the corneal thickness meets the surgical criteria, patients with 1000 degrees of myopia can also be considered for TFA, but whether they meet the surgical requirements should be evaluated by a specialist. In general, full femtosecond surgery is suitable for myopia patients with myopia of 100 degrees to 1,000 degrees and corneal thickness of not less than 480 micrometers. Although full femtosecond surgery can correct myopia up to 1,000 degrees, there are certain requirements for the corneal thickness of the patient, and it is necessary to go to the ophthalmology department of the hospital to improve the corresponding examination before the surgery, and develop a surgical plan based on the curvature of the cornea, corneal thickness and other indicators. Full femtosecond surgery, also known as femtosecond laser small incision corneal stromal lens removal, is suitable for all kinds of myopia and astigmatism eye diseases at the age of 18 years and above. The procedure utilizes a laser to polish the stroma to improve the patient’s vision. It has the advantages of smaller incisions, greater surgical precision, and very little surgical trauma. It is recommended that myopia patients consult a doctor to evaluate their condition and choose the appropriate treatment.
