儿童单侧性白内障后房型人工晶体植入术

Implantations fo posterior chamber intraocular lenses in children with monocular cataracts

总结４３例（外伤性３５例，先天性８例）儿童单侧性白内障后房型人工晶体植入术。术后矫正视力在０．５以上者外伤性白内障组占６５．７％；先天性白内障组占２５．０％。随访发现儿童眼对后房型人工晶体耐受良好，未见顽固性色素膜炎、大泡性角膜病变或继发性青光眼等严重并发症。影响儿童术后视力恢复的主要因素是弱视和后囊混浊，并讨论了防治方法。

AbstractExtracapsular cataract extractions with posteriorchamber intraocular lens implantations were performedon 43 eyes with monocular cataracts in children includ-ing 35 cases of traumatic and 8 cases of congenitalcataracts。65.7%of eyes with traumatic cataracts and25%of eyes with congenital cataracts achieved postoperative corrected visual acuities of≥0.5. It hasbeen found that children have good tolerance to poste-rior chamber intraocular lens and no serious ocularcomplications,such as persistent uveitis,bullouskeratopathy, or secondary glaucoma were seen.Themain factors influencing the visual acuity are opacifica-tion of the posterior lens capsule and amblyopia.Theirmethods of prevention and treatment were discussed.
