To evaluate the performance of medical contact lenses (CLs) for a wide range of clinical indications.
Prospective cross-sectional study.
A total of 281 eyes were evaluated in 281 consecutive patients (≥18 years of age; CL use ≥3 months) who visited the contact lens service in a tertiary academic clinic for a scheduled follow-up visit. The main outcome measured were clinical indications for CL wear; CL type; change in corrected distance visual acuity (CDVA) with CL use; CL wearing duration; CL wearing time; subjective performance measured using a visual analog scale (VAS) questionnaire (score range: 0-100); and effectiveness of the lens-selection algorithm.
Wearing CLs significantly improved CDVA compared to wearing spectacles (median change: -0.15 logMAR, range: 1.00 to -2.10; P<.001). Daily-wear CLs were worn by 77% of patients for a median of 15h/day (range: 5-18h/day), median 7 days/week (range: 1-7 days/week). High subjective scores were measured, with similar results obtained between the scleral lens and soft lens groups. The medical CL fitting was found to be generally effective (the overall satisfaction rating was ≥70 for 81% of patients).
Fitting CLs based on the lens-selection algorithm yielded positive clinical results, including improved visual acuity, satisfactory wearing time, and high overall subjective performance. Moreover, subjective performance was similar between users of scleral lenses and users of soft lenses. These results underscore the importance of prescribing scleral lenses and the need for tertiary eye clinics to offer patients a variety of CL types.
评估医用隐形眼镜（CL）在广泛临床适应症中的性能。
前瞻性横断面研究。
对连续就诊于一家三级学术诊所隐形眼镜服务部门进行定期随访的281例患者（≥18岁；使用CL≥3个月）的281只眼睛进行评估。主要测量结果包括CL佩戴的临床适应症；CL类型；使用CL后矫正远视力（CDVA）的变化；CL佩戴时长；CL佩戴时间；使用视觉模拟量表（VAS）问卷测量的主观性能（评分范围：0 - 100）；以及镜片选择算法的有效性。
与佩戴眼镜相比，佩戴CL显著改善了CDVA（中位数变化：-0.15 logMAR，范围：1.00至 -2.10；P <.001）。77%的患者佩戴日抛型CL，每天佩戴中位数为15小时（范围：5 - 18小时/天），每周佩戴中位数为7天（范围：1 - 7天/周）。主观评分较高，巩膜镜片组和软性镜片组结果相似。发现医用CL验配总体有效（81%的患者总体满意度评分≥70）。
基于镜片选择算法验配CL产生了积极的临床结果，包括视力提高、佩戴时间满意和总体主观性能良好。此外，巩膜镜片使用者和软性镜片使用者之间主观性能相似。这些结果强调了开具巩膜镜片处方的重要性以及三级眼科诊所为患者提供多种CL类型的必要性。
