To assess the refractive expectations of patients having elective cataract surgery.
Queen's Medical Centre, Nottingham, King's Mill Hospital, Sutton-in-Ashfield, and Kidderminster District Hospital, United Kingdom.
A prospective questionnaire study of patients attending a preoperative assessment clinic for elective cataract surgery was performed. Only first-eye cataract surgery patients were included. Patients were excluded if they had visually impairing ocular comorbidity or if they were mentally unable to complete the questionnaire.
One hundred eighty-nine questionnaires were received. Mean patient age was 74 years (range 41 to 97 years). Sixty-four percent of respondents were women, and 90% were retired. On 10-point Likert scales (0 lowest, 10 highest), median patient scores for the perceived likelihood of needing spectacles after surgery were 8 for both distance and near correction. Patients already wearing distance correction thought it significantly more likely that they would need distance glasses postoperatively than those who did not (median likelihood scores 9 and 1, respectively; P<.0001). Similar differences in expectations were demonstrated for near correction. Median score of the importance of not needing spectacles was 8 for both distance and near. Men scored this higher than women, but only for distance. There was a weak negative correlation between the importance of spectacle independence and patient age.
Patients who already wear spectacles expect to need them after cataract surgery. Those not already wearing spectacles do not expect to need them. This latter group is at particular risk for refractive disappointment and complaint. In general, patients consider the opportunity to be free of glasses as very important.
评估接受择期白内障手术患者的屈光预期。
英国诺丁汉女王医疗中心、阿什菲尔德萨顿的国王磨坊医院以及基德明斯特区医院。
对参加择期白内障手术术前评估门诊的患者进行前瞻性问卷调查研究。仅纳入首次行白内障手术的患者。若患者有影响视力的眼部合并症或精神上无法完成问卷则被排除。
共收到189份问卷。患者平均年龄74岁（范围41至97岁）。64%的受访者为女性，90%已退休。在10分制李克特量表（0分最低，10分最高）上，患者对术后需要眼镜可能性的感知评分，远视力矫正和近视力矫正的中位数均为8分。已佩戴远视力矫正眼镜的患者认为术后更有可能需要佩戴远视力眼镜，而未佩戴者则不然（可能性评分中位数分别为9分和1分；P<0.0001）。近视力矫正方面也显示出类似的预期差异。不需要眼镜的重要性评分，远视力和近视力的中位数均为8分。男性在这方面的评分高于女性，但仅在远视力方面。眼镜独立性的重要性与患者年龄之间存在弱负相关。
已佩戴眼镜的患者预计白内障手术后仍需要眼镜。尚未佩戴眼镜的患者则预计术后不需要眼镜。后一组患者尤其有屈光失望和抱怨的风险。总体而言，患者认为摆脱眼镜的机会非常重要。
