We performed qualitative and quantitative assessments of contact lens performance at 1 and 6 months among 23 patients enrolled in the Solitaire Bifocal Contact Lens Study. Overall satisfaction and comfort at 6 months was rated good to excellent in 83% and 84% of patients, respectively. Daytime acuity at distance and near were rated very good to excellent in 75% and 83% of subjects. Quantitative measurements of distance and near acuities at 1 month revealed 83% and 88% of subjects, respectively, seeing better than or equal to 20/25 or J1. At 6 months there was a moderate decrease in the measured distance acuity. A disparity in glare disability was noted, with 53% of subjects indicating significant glare problems but only 21% of glare tested patients having acuities worse than 20/40. Attrition from the study was highest in the first month and was more common among first-time contact lens users. Overall, this segmented bifocal contact lens is well-tolerated and provides good distance and near vision for presbyopic patients.
我们对参加了单焦点双焦隐形眼镜研究的23名患者在1个月和6个月时的隐形眼镜性能进行了定性和定量评估。6个月时，分别有83%和84%的患者对总体满意度和舒适度的评价为良好至优秀。75%和83%的受试者对白天远视力和近视力的评价为非常好至优秀。1个月时远视力和近视力的定量测量显示，分别有83%和88%的受试者视力优于或等于20/25或J1。6个月时，测得的远视力有适度下降。发现了眩光障碍方面的差异，53%的受试者表示存在明显的眩光问题，但在接受眩光测试的患者中，只有21%的患者视力低于20/40。研究中的脱落率在第一个月最高，并且在初次使用隐形眼镜的用户中更为常见。总体而言，这种分段双焦隐形眼镜耐受性良好，为老花眼患者提供了良好的远视力和近视力。
