| Popis: | PURPOSE: To compare ray-tracing aberrometry, Hartmann-Shack wavefront analysis, automated refraction, and manifest refraction in patients with echelette diffractive intraocular lenses (IOLs) and patients with monofocal IOLs with negative spherical aberration. METHODS: Pseudophakic patients implanted with an echelette diffractive IOL (Tecnis ZXR00; Johnson & Johnson Vision) and a control group consisting of patients implanted with a negative spherical aberration monofocal IOL (Tecnis ZCBOO, Johnson & Johnson Vision) were included in this study. Ray-tracing aberrometry (iTrace; Tracey Technologies Corp.), Hartmann-Shack wavefront analysis (LADARWave; Alcon Laboratories, Inc.), automated refraction (Topcon KR-8800; Topcon Medical Systems, Inc.), and manifest refraction spherical equivalent were performed 1 to 3 months postoperatively. RESULTS: Thirty-two eyes implanted with a ZXR00 IOL and 30 eyes implanted with a ZCBOO IOL were enrolled in this study. The ZXR00 IOL group yielded more myopic results with automated refactions (−0.62 ± 0.41 diopters [D]), Hartmann-Shack wavefront analysis (−0.85 ± 0.40 D), and ray-tracing aberrometry (−0.45 ± 0.64 D), compared to manifest refraction (−0.12 ± 0.44 D) ( P < .001). Hartmann-Shack wavefront analysis showed a statistically significant myopic shift (−0.39 ± 0.47 D) in the ZCBOO group compared to ray-tracing aberrometry, automated refraction, and manifest refraction spherical equivalent (−0.14 ± 0.56, −0.14 ± 0.50, and −0.06 ± 0.44 D, respectively; P < .001). CONCLUSIONS: Manifest refraction techniques unique to echelette technology should be used to avoid over-minus end points. Autorefractors and aberrometers commonly use near-infrared light; thus, myopic results are expected with echelette achromatic technology. [ J Refract Surg . 2020;36(5):334–339.] |
