Abstract Objective To compare the accuracy of postoperative refractive calculation with the six intraocularlens(IOL)calculation formulas(Kane,Hoffer QST,Barrett Universal Ⅱ,SRK-T,Hoffer Q and Holladay2)in long-axis cataract patients.Methods Retrospective case-series study.The clinical data of 44 cases(44 eyes)of long-axis cataract(＞26 mm)from March 2019 to March 2020 collected at Shenyang aier optometric hospital were analyzed.All patients underwent phacoemulsification combined with implantation of intraocular lens.The median absolute refraction errors(Med AE)and the proportion of the error within 0.50 D and 1.0 D of the six formulas were calculated and compared.Results Barrett Universal Ⅱ,Kane formula compared with SRK-T,Hoffer Q and Holladay 2 formula,Hoffer QST formula compared with Hoffer Q and Holladay2 formula,the error was smaller,and the differences were statistically significant(P<0.05).The proportions of the errors within 0.5 D of Kane,Barrett Universal Ⅱ,Hoffer QST,SRK-T,Holladay2 and Hoffer Q formulas were 36.4%,27.3%,22.7%,9.1%,4.5%,4.5%,respectively,the differences were statistically significant(P<0.001).The proportions within 1.0 were 70.5%,63.6%,50%,31.8%、11.4%,9.1%,respectively,the differences were statistically significant(P<0.05).The mean refractive error(ME)of Kane,Barrett Universal Ⅱ,Hoffer QST,SRK-T,Holladay2 and Hoffer Q formulas were 0.64±0.61,0.82±0.55,1.01±0.64,1.32±0.64,1.64±0.62,1.91±0.61,with statistically significant differences.Conclusion Among the six formulas,Kane,Barrett Universal Ⅱ and Hoffer QST are more accurate in the calculation of IOL degree for patients with long-axis cataract,the proportions within 0.5 D and 1.0 D are higher,are recommended for clinical use.All formulas drift towards farsightedness,so it is suggested to reserve a certain degree of myopia according to the axial length.
