Cluster Analysis of Patients Evaluated in Laser Refractive Surgery
ثبت نشده
چکیده
Methods: Wavefront aberrations were measured with wavefront aberrometry (ZyWave, Technolas Perfect Vision) on 1509 patients (57.9% females) with a mean age of 43.1 ± 12.0 years (range 18 to 71). We modeled the association of 15 pupil size adjusted (PSA) Zernike polynomials (3rd to 5th order) with age and refractive error using linear regression. A statistical method called clustering of linear models (CLM) was used to identify the clusters of Zernike polynomials.
