- Abstract
Objective: To compare the accuracy of SRK/T, Haigis and Barrett Universal II formulas by using Lenstar LS900 for the high myopia cataract patients. Methods: 40 cases(54 eyes) of cataract patients with high myopia who underwent phacoemulsification and intraocular lens implantation in our hospital from May 2018 to August 2018 were divided into three groups according to the axial length. Lenstar LS900 was used to measure the ocular biometrics and calculate the postoperative refraction predicted by SRK/T, Haigis and Barrett Universal II formulas. The actual diopter obtained one month after operation was compared with the diopter predicted by the formulas, and the accuracy of the formulas in different axial lengths was observed. Results: Comparison of the formulas in the groups: In group A, there was significant difference between Haigis formula and Barrett Universal II formula(P<0.05), but no significant difference was found between other formulas(P>0.05); in group B, there was no significant difference between SRK/T formula and Haigis formula(P>0.05), and there was significant difference between other formulas(P<0.05). In group C, the difference between the three formulas was statistically significant(P <0.05). Comparisons among different formulas: SRK/T formula and Haigis formula were statistically significant(P<0.05), but there was no significant difference between Barrett Universal II formula groups(P>0.05). Conclusion: Barrett Universal II formula showed good accuracy in each axial length, and the accuracy did not decrease with the axial growth for the high myopia cataract patients. With the increase of axial length, the accuracy of SRK/T formula decreases gradually. When AL>30 mm, the accuracy of Haigis formula is better than that of SRK/T formula.
