[Abstract]:PurposeThe application of wavefront aberration theory in ophthalmology has attracted more and more attention.The wavefront aberration instrument can not only measure the high order aberrations of human eyes, but also can be used to measure the low order aberrations. The wavefront aberration technique can be used to analyze the aberrations and other clinical aspects of ophthalmology.At present, wavefront aberration theory is widely used in the analysis of high order aberrations of human eyes, but there is little research on low order aberrations.By comparing different optometry methods, the accuracy of Zywave wavefront aberration instrument and conventional optometry for diopter measurement is studied in this paper.To investigate the value of Zywave wavefront aberration measurement before laser in situ keratomileusism (LASIKI), and to provide a theoretical basis for the application of wavefront aberration in the measurement of low order aberration.MethodFrom June 2011 to August 2011, 46 patients (84 eyes) with myopia underwent excimer laser surgery in our hospital were randomly selected.Computer automatic optometry, shadow optometry and principal optometry were used before operation. The spherical, cylindrical and equivalent spherical specular degrees were measured and statistically analyzed by using a comprehensive refractive wavefront aberration instrument (Zywave wavefront aberration).Statistical analysis: the data collected were analyzed by SPSS17.0 software (paired t test, mean x 鹵s).Result1.In the low degree myopia group: compared with the optometry results of wavefront aberration instrument, computer optometry and shadow optometry had statistical significance.There was no significant difference between the main refractive index and wavefront aberration instrument.2.In moderate myopia group, computer optometry, comprehensive optometry, principal optometry and shadow optometry were compared with those of wavefront aberration instrument respectively.3.In the group of high myopia, computer optometry, comprehensive optometry, optometry and principal optometry were compared with the optometry of wavefront aberration instrument respectively.Conclusion1.The results of low myopia wavefront aberration instrument are in good agreement with the results of comprehensive optometry.2.The results of computer optometry for medium and high myopia can be used to supplement the results of wavefront aberration instrument optometry in order to achieve the aim of fine adjusting astigmatism.
