A prospective study was undertaken to evaluate the success rate in fitting the Alges bifocal contact lens, and to determine which subject characteristics were associated with success. Fifty-eight presbyopic subjects with healthy eyes were included in the study. Thirteen subjects (22.4%) were screened out and discontinued after the fitting examination because of visual problems. Lenses were dispensed to 45 subjects (the dispensed group). Thirteen of these subjects were discontinued. Thirty-two subjects (71.1%) were considered successful after wearing their optimum lenses for 1 month. The successful group was interviewed by telephone after 3 months of wear. Two of these subjects were actually a "qualified" success. After 9 months, the successful group was again interviewed by telephone. Twenty-four subjects of the dispensed group were still considered to be optimally successful, five subjects were considered to be a "qualified" success and three subjects had discontinued lens wear. Our success rate for screened patients after 9 months was 64.4%. Two subject characteristics that were associated with success were a previous history of contact lens wear (p = 0.0065) and a near-point stereoacuity better than 100 s of arc with the Alges lens (p = 0.01).
进行了一项前瞻性研究，以评估佩戴Alges双焦点隐形眼镜的成功率，并确定哪些受试者特征与成功相关。该研究纳入了58名眼睛健康的老花眼受试者。在配镜检查后，有13名受试者（22.4%）因视力问题被筛选出来并停止参与研究。为45名受试者（配镜组）配发了镜片。其中13名受试者停止了佩戴。在佩戴最佳镜片1个月后，32名受试者（71.1%）被认为佩戴成功。在佩戴3个月后，通过电话对成功组进行了访谈。其中两名受试者实际上是“合格”的成功案例。在佩戴9个月后，再次通过电话对成功组进行访谈。配镜组中有24名受试者仍被认为是最佳成功案例，5名受试者被认为是“合格”的成功案例，3名受试者停止了镜片佩戴。9个月后，我们对筛选出的患者的成功率为64.4%。与成功相关的两个受试者特征是既往有隐形眼镜佩戴史（p = 0.0065）以及使用Alges镜片时近点立体视敏度优于100秒弧度（p = 0.01）。
