摘要
Abstract
Objective To analyze and evaluate the consistency analysis of automatic computerized refractometer Topcon KR-8900, Lenstar LS900 and corneal topography Atlas 9000 in measuring preoperative corneal curvature of patients with cataract and to guide the preoperative examination of cataract.Methods Eighty-three cataract patients (89 eyes) who were admitted and treated in Ophthalmic Center of Foshan Second People's Hospital in August 2017were selected.Automatic computerized refractometer Topcon KR-8900, Lenstar LS900 and corneal topography Atlas9000 were used to measure flat corneal curvature (K1), steep corneal curvature (K2) and corneal astigmatism degree and axial scan to calculate mean keratometry (Km), astigmatism vector J0 and J45.ANOVA was used to analyze the difference among the three groups.Paired t test was used to compare the difference between two pairs.Bland-Altman test was used for consistency analysis.Results (1) The difference of K1, K2, Km value measured by three instruments was statistically significant (P<0.001).There was no statistically significant difference in values measure by Lenstardifference between Lenstar LS900 and Atlas 9000 was statistically significant (P=0.017).When J45 was measured, there was no statistically significant difference among the three instrument groups and the comparison between the two groups (P>0.05). (2) The Bland-Altman test found that the consistency of the three instruments was poor in measuring corneal curvature and corneal astigmatism.Conclusion Automatic computerized refractometer Topcon KR-8900, Lenstar LS900 and corneal topography Atlas 9000 can easily and quickly measure the corneal curvature.However, the consistency among the three instruments is poor, which deserves to be paid attention to and carefully select results.关键词
