摘　　要：Purpose:To investigate a quantitative method to measure decentration distance(DD) and analyze the DD of four kinds of intraocular lenses (IOLs).Methods:The pseudophakic eye photos were taken under the slit lamp after the IOLs were implanted a year or longer. Then the images were inputted into a computer and the Photoshop software was applied to analyze the DD. Four kinds of IOLs were analyzed, including AcrySof MA60BM (11 eyes), Allergan SA40N (11 eyes), AcrySof SA60AT/SA30AL (5 eyes), Corneal Quattro (4 eyes).Results:The mean value of DD was (0.264 3±0.157 4)mm in the AcrySof MA60BM group,(0.353 6±0.171 9)mm in the Array SA40N group,(0.309 9±0.152 9)mm in the SA60AT/SA30AL group, and (0.326 1±0.187 7)mm in the Quattro group. The difference of the DD values among these 4 kinds of IOLs had no statistic significance (F=0.506,P=0.681) and the values were not equal to zero (t=10.508, P < 0.001).Conclusion:The Photoshop method is a simple and efficient way for DD analysis. The modern foldable posterior-chamber-IOLs have good centration performances when implanted into the capsular bags.
