人工晶状体( intraocular lens, IOL)在眼内常有不同程度的倾斜、偏心或旋转,是影响白内障患者术后视觉质量的重要因素。以往常用视力来评价视觉质量,近年来引入像差、调制传递函数( modulation transfer function, MTF)、主观视觉评价等新指标,表明IOL偏斜将引起视力下降、像差增加、MTF下降、屈光不正等。因此,更好地评价IOL偏斜对视觉质量的影响,将对IOL选择、定位和白内障个体化治疗具有指导意义。

lntraocular lens ( lOL) often has different degrees of tilt, decentration and rotation in the eye. The deflection of lOL is an important factor to impact on the visual quality of the patients with cataract surgeries. Vision was commonly used to evaluate visual quality before. ln recent years, some new methods are also introduced to evaluate visual quality, such as optical aberration, modulation transfer function ( MTF ) and subjective visual perception. They show that the lOL deflection will cause decreases in eyesight and MTF, cause increase in aberration, lead to ametropia and so on. Therefore, a better evaluation of the effects of lOL deflection on visual quality, has significance for lOL selection, positioning and cataract individualized treatment.
