Objective To explore different cataract morphology on the visual and optimal performance.Methods Cataract patients who visited the Eye Hospital of China Medical University from March 2013 to August 2013 with a best corrected visual acuity (LogMAR) of 0.3 or better,were classified into 3 groups:cortical cataract group (44 eyes of 41 subjects),nuclear cataract group (39 eyes of 36 subjects),posterior cataract group (38 eyes of 36 subjects),BCVA were measured with phoropter,objective scatter index (OSI),MTF cut off and Strehl ratio (SR) were measured with OQAS.Results The best corrected visual acuity (LogMAR) were 0.23±0.10 in the cortical group,0.23±0.08 in the nuclear group and 0.25±0.10 in the posterior group,BCVA did not differ significantly for cataract of the 3 types (F =0.68,P =0.51);The age,LN(OSI),MTF cut Off and OR were 64.57±6.25、1.35±0.63、11.85±4.24、0.09±0.02 in the cortical group,69.90±5.01,1.01±0.43,14.82±5.50,0.10±0.03 in the nuclear group,61.03±9.52,1.85±0.58,8.71±6.36,0.08±0.03 in the posterior group respectively (F =15.17,F =22.49,F =12.38,F =11.8;P ＜0.05);In Bonferroni test,OSI,MTF cut off and SR were significantly different in cataracts of different morphologies (P ＜0.05);Age of cortical cataracts was older than that of nuclear and posterior cataracts;From nuclear,cortical,posterior cataracts OSI deteriorate in order;From nuclear,cortical,posterior cataracts MTF cut off decreased in order;SR in nuclear cataracts were significant better compared with that in cortical and posterior cataracts (P ＜0.05);no significant differences were found between the cortical and posterior cataracts (P ＞0.05).Correlations between BCVA and OSI were r =0.41,r =0.33,r =0.32;P ≤0.05) in cortical cataracts,nuclear cataracts and posterior cataracts (P ＞0.05);however,BCVA had no significant correlation with OSI in any cataracts (P ＞0.05).OSI correlated with MTF cut off in any cataracts (r =-0.88,P ＜0.01;r =-0.70,P ＜0.01;r =-0.76,P ＜0.01).Conclusions OSI,MTF cut off and SR can objectively reflect the influence of cataract morphology on quality of vision,and the influence is most notable in posterior cataract.
