Presbyopia treatments using various modalities have been developed recently; however, no standard criteria exist for the diagnosis and treatment endpoint. This study assessed the relationship between the near visual acuity (NVA) and the subjective symptoms of phakic presbyopia and determined the numerical NVA threshold to diagnose phakic presbyopia and evaluate the effectiveness of presbyopia treatment. The binocular distance, NVA with habitual correction, and monocular conventional VA were measured. Patients were asked about their awareness of presbyopia and difficulty performing near tasks. This prospective observational study included 70 patients (mean age, 56 years; range, 32-77). Most patients became aware of presbyopia in their late forties, although some had difficulty with vision-related near tasks before becoming aware of presbyopia. Eighty three percent of patients (20/24) experienced difficulty with near vision-related tasks even with excellent NVA at 40 cm with habitual correction of 0.0 logMAR (20/20 in Snellen VA). In conclusion, the current study showed that patients became aware of presbyopia in their late forties, although some had difficulty with near vision-related tasks before becoming aware of presbyopia. Further investigation should include the proposal of appropriate diagnostic criteria for presbyopia and better management for patients with presbyopia.
近年来已开发出多种治疗老花眼的方法；然而，对于诊断和治疗终点尚无标准的评判标准。本研究评估了有晶状体老花眼的近视力（NVA）与主观症状之间的关系，并确定了诊断有晶状体老花眼和评估老花眼治疗效果的数字NVA阈值。测量了双眼远视力、习惯性矫正下的近视力以及单眼常规视力。询问患者对老花眼的认知情况以及进行近距任务时的困难程度。这项前瞻性观察研究纳入了70例患者（平均年龄56岁；范围32 - 77岁）。大多数患者在接近五十岁时开始意识到老花眼，尽管有些患者在意识到老花眼之前就已经在与视力相关的近距任务中遇到困难。83%的患者（20/24）即使在40厘米处习惯性矫正视力为0.0 logMAR（Snellen视力表20/20）时近视力极佳，仍在与近视力相关的任务中遇到困难。总之，当前研究表明患者在接近五十岁时开始意识到老花眼，尽管有些患者在意识到老花眼之前就已经在与近视力相关的任务中遇到困难。进一步的研究应包括提出合适的老花眼诊断标准以及对老花眼患者进行更好的管理。
