ABSTRACT

·AlM: To investigate the distribution and related factors of corneal spherical aberration in the age-related cataract patients, and to provide a scientific basis for the application of aspheric intraocular lens ( lOL ) in cataract surgery patients. · METHODS: Retrospective study of 509 age -related cataract patients of 610 eyes in our hospital. Corneal spherical aberration, corneal curvature, corneal astigmatism and corneal Q -value were examined by iTrace visual function analysis. Statistical software SPSS16.0 was used to analyze statistically. · RESULTS: The range of corneal spherical aberration was 0 ~1.800μm. The mean coefficient of corneal spherical aberration was 0.266 ±0.010μm. Corneal spherical aberration was no significantly correlation with age, corneal curvature, corneal astigmatism ( r =0.71, 0.56, 0.93, P>0.05 ). There was positive correlation between corneal spherical aberration and Q-value ( r=0.086, P=0.03). · CONCLUSlON: Corneal spherical aberration varied greatly among age-related cataract patients.The choice of asphericity intraocular lens should be a matter of personal choice.
