不同视功能评价方法在早期白内障手术指征评估中的应用

Application of different visual function examinations on evaluation of surgery indication in early cataracts

随着白内障手术从复明性手术时代进入屈光性手术时代,其意义和指征发生了显著变化。视觉质量取代视力成为评价患者是否具有手术适应证的最重要因素,但目前对于采用何种视觉质量评价指标为决定手术的依据尚无定论。目前研究中所采用的主观视觉指标包括视力、对比敏感度、对比度视力、视功能生存质量量表;客观视觉指标包括客观散射指数、调制传递函数与调制传递函数截止频率和斯特列尔比等。推荐以客观方法评价为主,主、客观评价相结合的综合性分析指标作为早期白内障手术的时机选择依据,为提高患者术后满意度提供保障。

As cataract surgery has entered the era of refractive surgery from the era of rejuvenation surgery,its significance and indications have undergone significant changes.The influence of visual quality instead of visual acuity has become the most important factor in evaluating whether a patient has surgical indications,but at present,there is no conclusion on which visual quality evaluation indicators is used to determine the basis for surgery.The subjective visual indicators used in the present study included visual acuity,contrast sensitivity,contrast visual acuity and visual function quality of life scale;objective visual indicators include objective scattering index,modulation transfer function,modulation transfer function cutoff frequency and Strehl ratio,etc.It is recommended to use objective evaluation as the basis and combining with the subjective indicators for timing selection of early cataract surgery,to provide a guarantee for improving postoperative satisfaction of patients.
