To validate the Easee web-based tool for the assessment of visual acuity in patients who underwent cataract surgery.
University Eye Clinic Maastricht, Maastricht, the Netherlands.
Prospective method comparison study.
Subjects aged between 18 and 69 years who underwent cataract surgery on 1 or both eyes at the Maastricht University Medical Center+ were eligible to participate in this study. The uncorrected (UDVA) and corrected distance visual acuity (CDVA) assessments were performed using the web-based tool (index test) and conventional ETDRS and Snellen charts (reference tests). The outcomes of the different tests were expressed in logMAR, and a difference of <0.15 logMAR was considered clinically acceptable.
46 subjects with 75 operated eyes were included in this study. The difference of the UDVA between the web-based tool and ETDRS or Snellen was -0.05 ± 0.10 logMAR ( P < .001 [0.15; -0.26]) and -0.04 ± 0.15 logMAR ( P = .018 [0.24; -0.33]), respectively. For the CDVA, these differences were -0.04 ± 0.08 logMAR ( P < .001 [0.13; -0.21]) and -0.07 ± 0.10 logMAR ( P < .001 [0.13; -0.27]), respectively. The Pearson correlation coefficients between the web-based tool and ETDRS were maximally 0.94 and compared with Snellen 0.92. In total, 73% to 88% of the visual acuity measurement differences were within 0.15 logMAR.
The web-based tool was validated for the assessment of visual acuity in patients who underwent cataract surgery and showed clinically acceptable outcomes in up to 88% of patients. Most of the participants had a positive attitude toward the web-based tool, which requires basic digital skills.
验证 Easee 网络工具在白内障手术后患者视力评估中的有效性。

前瞻性方法比较研究。
在马斯特里赫特大学医学中心接受单眼或双眼白内障手术的年龄在 18 至 69 岁之间的患者有资格参加本研究。使用网络工具（指标测试）和传统的 ETDRS 和 Snellen 图表进行未矫正（UDVA）和矫正距离视力（CDVA）评估。不同测试的结果用 logMAR 表示，临床可接受的差异<0.15 logMAR。
本研究共纳入 46 名 75 只手术眼患者。网络工具与 ETDRS 或 Snellen 之间 UDVA 的差异分别为-0.05±0.10 logMAR（P<0.001[0.15；-0.26]）和-0.04±0.15 logMAR（P=0.018[0.24；-0.33]）。对于 CDVA，这些差异分别为-0.04±0.08 logMAR（P<0.001[0.13；-0.21]）和-0.07±0.10 logMAR（P<0.001[0.13；-0.27]）。网络工具与 ETDRS 之间的 Pearson 相关系数最高为 0.94，与 Snellen 的相关系数为 0.92。总的来说，73%至 88%的视力测量差异在 0.15 logMAR 以内。
网络工具在白内障手术后患者的视力评估中得到验证，在高达 88%的患者中具有可接受的临床结果。大多数参与者对需要基本数字技能的网络工具持积极态度。
