白内障患者功能性视力的研究现状

Research status of functional vision in cataract patients

功能性视力检查包括连续性功能视力、眼内散射光、波前像差、点扩散函数、调制传递函数、对比敏感度、眩光敏感度、双眼视觉功能等,作为一种全面评估视觉质量的方法,广泛应用于早期视力尚未受损但有主观视觉损害的白内障患者,也可用于客观评价屈光性、老视矫正性白内障手术后患者是否能看得见,看得清晰,看得舒服。

Functional vision examination comprises of continuous functional visual acuity, intraocular straylight, wavefront aberration, point spread function, modulation transfer function, contrast sensitivity, glare sensitivity, binocular visual function, etc. Functional vision examination is a comprehensive and useful tool, which is widely used in evaluating cataract patients whose visual acuity is good at early stage but objective quality of vision is bad, also in evaluating whether the patients could not only see but also see clearly and comfortably after refractive and presbyopia-correcting cataract surgery.
