项目介绍
准分子激光原位角膜磨镶术（LASIK）在一般公立医院参考费用约¥5600-12000，三甲医院参考费用约¥8000-15000，常用于相关诊断评估与就医安排，费用随医院及地区有所差异。
主要用途
Primary clinical use is correction of refractive errors including myopia, hyperopia, and astigmatism in eligible adults (18+ years) with stable vision. Applicable scenarios include occupational requirements (e.g., military, pilots), lifestyle-driven vision independence, and dissatisfaction with glasses/contacts — provided strict candidacy criteria (adequate corneal thickness, healthy ocular surface, no keratoconus, no active autoimmune disease) are met.
正常值范围
LASIK is not a diagnostic laboratory test with numerical 'values' or 'ranges'; it is a surgical procedure. Therefore, there is no 'normal range' for LASIK itself. Preoperative assessments (e.g., corneal thickness, refractive error, pupil size, wavefront aberrations) have individual reference ranges: corneal thickness ≥500 µm, spherical equivalent −12.00 to +6.00 D, cylinder ≤6.00 D, pupil diameter <8 mm in dim light, wavefront RMS error <0.3 µm (low-order), and stable refraction (>1 year).
偏低可能原因
Low preoperative corneal thickness (<480–500 µm), low corneal curvature (flat keratometry <39.0 D), low tear film stability (Schirmer test <10 mm/5 min or TBUT <5 sec), low endothelial cell density (<2000 cells/mm²), and low refractive stability (progressive myopia >0.5 D/year).
偏高可能原因
High preoperative myopia (>−10.00 D), high astigmatism (>4.00 D), high corneal curvature (steep keratometry >48.0 D), high higher-order aberrations (RMS >0.5 µm), and high intraocular pressure (>22 mmHg) — all of which may increase surgical risk or contraindicate standard LASIK.
