目的：评价准分子激光屈光性角膜切削术(PRK)和准分子激光原位角膜磨镶术(LASIK)术后老花眼患者对传统单视(主眼矫正距离)和交叉单视(主眼矫正近)的单视效果和患者满意度。设计：回顾性观察病例系列。研究对象。方法：选择1995年12月至1998年6月接受准分子激光屈光手术治疗的144例45岁以上患者，手术结果为单视(近视等效球镜-0.50~+0.50D，近视SE-3.75~-1.00D，屈光参差1.00D或以上)、交叉屈光不正(优势眼矫正近视，非优势眼矫正远视)和完全矫正(双眼矫正-0.50~+0.50)。主要观察指标：术前术后视力和屈光度。结果：患者对单眼视觉的满意度。有42例患者的手术结果为机械通气。MV组远视力SE为-0.04+/-0.27D，近视力SE为-1.95+/-0.70D，屈光参差为1.92+/-0.74D。患者对MV的满意率为88%。12例患者获得交叉MV。所有交叉MV患者的视力均满意。患者对MV的满意度与性别、初次手术年龄、术前单视试验、治疗的偏侧性、单视类型或结果的可预测性无关。结论：单视可能是考虑屈光手术的老花眼患者的一种有价值的选择。交叉单视可以产生令人满意的视觉效果。眼科2001；美国眼科学会108：1430-1433(C)2001。
Purpose: To characterize monovision outcomes and patient satisfaction with conventional monovision (dominant eye corrected for distance) and crossed monovision (dominant eye corrected for near) in presbyopic individuals after excimer laser photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). Design: Retrospective observational case series.Participants. One hundred forty-four consecutive patients, 45 years or older, who were treated with excimer laser refractive surgery between December 1995 and June 1998.Methods: Patients in whom the surgical outcome was monovision (MV) (distance vision spherical equivalent [SE] -0.50 to +0.50 diopter (D), near vision SE -3.75 to -1.00 D and anisometropia 1.00 D or greater), crossed MV (dominant eye corrected for near vision and the nondominant eye for distance vision) and full correction (bilateral SE -0.50 to +0.50) were identified. Data were abstracted and analyzed statistically.Main Outcome Measures: Preoperative and postoperative visual acuity and refraction. Patient satisfaction with monovision.Results. Forty-two patients had surgical outcome of MV. In MV patients, the average distance vision SE, near vision SE, and anisometropia were -0.04 +/-0.27 D, -1.95 +/-0.70 D, and 1.92 +/- .74 D, respectively. Patient satisfaction was 88% with MV. Twelve patients attained crossed MV. All patients with crossed MV were satisfied with their vision. Patient satisfaction with MV showed no relationship to gender, age at initial surgery, preoperative trial of monovision, laterality of treatment, type of monovision, or predictability of outcomes.Conclusions: Monovision may be a valuable option for presbyopic individuals considering refractive surgery. Crossed monovision can result in satisfactory visual outcomes. Ophthalmology 2001;108:1430-1433 (C) 2001 by the American Academy of Ophthalmology.
