项目介绍
YAG激光后囊膜切开术在一般公立医院参考费用约¥210-640，三甲医院参考费用约¥300-800，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 treatment of posterior capsule opacification (PCO) — the most common long-term complication after cataract surgery — to restore visual clarity without invasive surgery. Indicated when PCO causes significant visual symptoms (e.g., glare, blur, decreased contrast sensitivity) and best-corrected visual acuity declines to ≤20/40 despite refractive correction. Also used in select cases of secondary membrane-induced pupillary block or aphakic glaucoma.
正常值范围
YAG laser posterior capsulotomy is a surgical procedure, not a laboratory test with numerical values; therefore, there is no 'normal range' or quantitative reference interval. Success is assessed clinically by restoration of clear visual axis and improvement in visual acuity (typically ≥20/40 Snellen), absence of intraocular complications (e.g., IOP spike >30 mmHg, cystoid macular edema, retinal detachment), and complete opening of the opacified posterior capsule (typically 3–4 mm diameter).
偏低可能原因
N/A — This is not a quantitative diagnostic test; 'low values' do not apply. Clinical failure (e.g., incomplete capsulotomy, persistent visual impairment) may result from inadequate laser energy, poor patient fixation, dense fibrosis, anterior capsule involvement, or operator inexperience.
偏高可能原因
N/A — This is not a quantitative diagnostic test; 'high values' do not apply. Adverse outcomes (e.g., elevated intraocular pressure, macular edema, retinal tear) are complication-related, not value-based. Excessive laser energy or excessive shot count (>100 pulses) may increase risk of IOP spike, lens pitting, or vitreous disturbance.
