Significance of intraocular scattered light and contrast sensitivity to assess the true visual quality in cataract patients / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

To analyze the significance of intraocular scattered light and contrast sensitivity in cataract patient's visual quality.METHODS: Seventy-three cases of cataract patients ( 120 eyes ) in our department from January 2012 to January 2014 were selected, of which 32 cases (52 eyes) were cortical cataract, 18 cases ( 33 eyes ) were nuclear cataract, 23 cases ( 35 eyes ) were posterior subcapsular cataract, and 40 normal persons ( 40 eyes ) were as the normal group. The full-eye corneal astigmatism and total astigmatism were observed in all those enrolled. The contrast sensitivity of different perspective was checked by automatic glare contrast sensitivity tester.RESULTS: The corneal astigmatism and full eye total astigmatism in the cortical cataract group, nuclear cataract group and the posterior capsule cataract group was significantly higher than that in the normal group( P0. 05). The contrast sensitivity in the cortical cataract group, nuclear cataract group and posterior subcapsular cataract group in the whole band were significantly lower than the normal group (P<0. 05). The contrast sensitivity of posterior subcapsular cataract group in the whole band was significantly lower than cortical cataract groups and nuclear cataract group(P<0. 05).CONCLUSlON: lntraocular scatter light and contrast sensitivity joint inspection can effectively evaluate the visual quality of cataract patients, which lead to early treatment.
