To evaluate the accuracy of a new automated refractor (HRK-8000A) using the Hartmann-Shack sensor in eyes with previous corneal refractive surgery or intraocular lens (IOLs) implantation.
Asan Medical Center, Seoul, South Korea.
Retrospective nonrandomized clinical study.
Refractive errors were evaluated after more than 1 month postoperatively. Subjective refractive error measurements were obtained by the same practitioner. Refractive error measurements were obtained with the Hartmann-Shack sensor refractor and a conventional refractor (KR 8800).
There were 121 eyes (121 patients) with previous corneal refractive surgery and 122 eyes (122 patients) with previous cataract surgery. The results of refractive error measured by the Hartmann-Shack sensor refractor were more similar to subjective refraction than those measured by the conventional refractor in both groups. In both groups, the mean spherical equivalent (SE) for the subjective refraction showed better agreement with the automated refraction measured by the Hartmann-Shack sensor refractor (limits of agreement [LoA], -0.66 to +0.65 diopters [D] and -0.47 to +0.41 D, respectively) than the automated refraction measured by the conventional refractor (LoA, -1.66 to +0.58 D and -1.34 to +0.60 D, respectively). In both groups, the Jackson cross-cylinder at axis 0 degrees and 45 degrees from the automated refraction by the Hartmann-Shack sensor refractor and conventional refractor showed similar agreement with the subjective refraction.
The Hartmann-Shack sensor automated refractor gave reliable and valid objective refraction results in patients who have had cataract or corneal refractive surgery.

使用哈特曼-夏克传感器评估新型自动验光仪（HRK-8000A）在曾接受角膜屈光手术或人工晶状体（IOL）植入术的眼中的准确性。

回顾性非随机临床研究。
术后1个月以上评估屈光不正。由同一名从业者进行主观屈光不正测量。使用哈特曼-夏克传感器验光仪和传统验光仪（KR 8800）进行屈光不正测量。
有121只眼（121例患者）曾接受角膜屈光手术，122只眼（122例患者）曾接受白内障手术。在两组中，哈特曼-夏克传感器验光仪测量的屈光不正结果比传统验光仪测量的结果更接近主观验光。在两组中，主观验光的平均球镜等效度（SE）与哈特曼-夏克传感器验光仪测量的自动验光结果（一致性界限[LoA]分别为-0.66至+0.65屈光度[D]和-0.47至+0.41 D）的一致性优于与传统验光仪测量的自动验光结果（LoA分别为-1.66至+0.58 D和-1.34至+0.60 D）。在两组中，哈特曼-夏克传感器验光仪和传统验光仪在0度和45度轴向上的自动验光的杰克逊交叉柱镜与主观验光显示出相似的一致性。
哈特曼-夏克传感器自动验光仪在白内障或角膜屈光手术患者中给出了可靠且有效的客观验光结果。
