Abstract:
AIM: To evaluate the refractive status through computer refractometer and OPD-Scan III auto refractometer in cataract patients after extended depth of focus(EDOF)intraocular lens implantation.METHODS: Retrospective observational study. A total of 61 cases(76 eyes)that received phacomulsification and implanted with TECNIS® Symfony ZXR00 intraocular lens in Shanghai Eye Diseases Prevention & Treatment Center from May 2022 to May 2023 were collected. Measurements from the computer refractometer, OPD-Scan III auto refractometer, and subjective refraction, were taken from all patients on the same day postoperatively.RESULTS: There were statistical significant difference in sphere(S)and spherical equivalent(SE)readings from the computer refractometer and subjective refraction(all P<0.01), with mean differences of -0.67±0.37 D and -0.75±0.35 D, respectively, and the S and SE obtained from computer refractometer more incline to myopia than those from subjective refraction; there were statistical significant difference in computer refractometer and subjective refraction(P<0.01), with a relative small absolute difference(0.21±0.24 D). The S, cylinder(C)and SE of computer refractometer(S, C, SE)were positively correlated with subjective refraction(r=0.7994, 0.7929, and 0.8118, respectively, all P<0.01). Additionally, there were statistical significant differences in S, C and SE of OPD-Scan Ⅲ and subjective refraction(P<0.01), and the absolute differences of S(0.63±0.36 D), C(0.35±0.26 D)and SE(0.53±0.36 D)were small. Furthermore, the S, C and SE of OPD-Scan Ⅲ were positively correlated with subjective refraction(r=0.4410, 0.4982, 0.5224, all P<0.01).CONCLUSION: In patients who received implantation of EDOF lenses, the consistency of computer refractometer, OPD-Scan III auto refractometer and subjective refraction was good. The average difference of the S and SE obtained via computer refractometer was large, but both exhibited a myopic shift relative to those derived from subjective refraction, and the C values demonstrated minimal discrepancy. Furthermore, the differences between OPD-Scan III auto refractometer and subjective refraction were small, but the direction of the difference is unstable, sometimes it is myopic deviation, while sometimes it is hyperopic deviation.
