Comparative Analysis of the Effect of IOL Master and A-Ultrasound Combined Corneal Topography Measurement on IOL Degree
Objective:This article will conduct a comparative analysis to explore the impact and accuracy of IOL Master versus the combination of A-ultrasound and corneal topography in determining the power of intraocular lenses.Methods:36 cataract patients(52 eyes)who underwent phacoemulsification and intraocular lens(IOL)implantation in our ophthalmology department were selected.Among them,25 cases of age-related cataracts and 11 cases of concurrent cataracts were divided into the IOL Master group and the A-ultrasound combined corneal topography measurement group.And analyze each group using different methods.Results:In the IOL Master group,there was no significant difference in preoperative IOL Master and A-ultrasound measured axial length(P>0.05),but there was a significant difference(P<0.05)in patients with axial length exceeding 26mm;There was a statistically significant difference(P<0.01)between the IOL Master and the corneal curvature evaluated by corneal topography;3 months post-operation,a notable disparity(P<0.05)was observed between the group measured with IOL Master and the group assessed through the combination of A-ultrasound and corneal topography.Conclusion:When the eye axis length is normal,the IOL Master combined with A-ultrasound corneal topography can display higher eye axis length and IOL degree.
