This study examines the relationship of subjective glare to refraction and visual acuity, respectively, 1 year after surgery in 435 patients who underwent radial keratotomy for nearsightedness in the Prospective Evaluation of Radial Keratotomy (PERK) study. Patients were asked if they experienced glare in bright light. Of the 425 responding, 200 patients responded "no" and 225 patients responded "yes." We found no statistically significant difference in the mean value of the cycloplegic refraction 1 year after surgery in these two patient groups. (Mean cycloplegic refraction: no = -.48, yes = -.52, p = .73). We also found no difference between these groups with respect to the percent of patients with uncorrected visual acuity of 20/40 or better 1 year after surgery (no = 79%, yes = 76%, p = .46).
在“放射状角膜切开术前瞻性评估（PERK）研究”中，本研究对435例因近视接受放射状角膜切开术的患者术后1年主观眩光与屈光及视力之间的关系分别进行了研究。询问患者在强光下是否会经历眩光。在425名做出回应的患者中，200名患者回答“否”，225名患者回答“是”。我们发现这两组患者术后1年睫状肌麻痹验光平均值无统计学显著差异。（平均睫状肌麻痹验光：否= -0.48，是= -0.52，p = 0.73）。我们还发现，这两组患者术后1年未矫正视力达到20/40或更好的患者百分比无差异（否= 79%，是= 76%，p = 0.46）。
