主要用途
SMILE is a minimally invasive refractive surgery primarily used to correct myopia and myopic astigmatism. Its main clinical uses include: permanent vision correction for eligible adults aged 22–45 years, reduction or elimination of dependence on spectacles or contact lenses, treatment of stable refractive errors with low risk of dry eye and corneal ectasia compared to LASIK, and preference in patients with thin corneas, contact lens intolerance, or occupations requiring rapid visual recovery (e.g., military, pilots).
正常值范围
SMILE is a surgical procedure, not a diagnostic laboratory test; therefore, it has no numerical 'normal range' or quantitative biomarker values. Clinical eligibility for SMILE is determined by preoperative ophthalmic measurements including: spherical equivalent refraction (−0.50 to −10.00 D), cylinder ≤ −5.00 D, central corneal thickness ≥ 500 μm, residual stromal bed ≥ 250 μm, pupil size < 6 mm in dim light, and stable refraction (change ≤ 0.50 D/year for ≥ 2 years).
偏低可能原因
Low values are not applicable to SMILE as it is not a quantitative test. However, contraindications that may preclude SMILE candidacy include: insufficient corneal thickness (<500 μm), thin residual stromal bed (<250 μm), keratoconus or forme fruste keratoconus, severe dry eye syndrome, active ocular inflammation or infection, and uncontrolled autoimmune disease affecting the cornea.
偏高可能原因
High values are not applicable to SMILE as it is not a quantitative test. However, factors disqualifying patients due to excessive parameters include: myopia > −10.00 D, astigmatism > −5.00 D, corneal curvature outside 38–48 D, abnormal corneal topography (e.g., asymmetry index > 1.2, inferior-superior asymmetry > 1.5 D), and abnormally high intraocular pressure (>24 mmHg) without glaucoma workup.
