PURPOSE
To assess the web accessibility and readability of patient-oriented educational websites for cataract surgery.
DESIGN
Cross-sectional electronic survey.
PARTICIPANTS
Websites with information dedicated to educating patients about cataract surgery.
METHODS
An incognito search for "cataract surgery" was performed using a popular search engine. The top 100 patient-oriented cataract surgery websites that came up were included and categorized as institutional, private practice, or medical organization according to authorship. Each site was assessed for readability using 4 standardized reading grade-level formulas. Accessibility was assessed through multilingual availability, accessibility menu availability, complementary educational video availability, and conformance and adherence to the Web Content Accessibility Guidelines (WCAG) 2.0. A standard t test and chi-square analysis were performed to assess the significance of differences with regard to readability and accessibility among the 3 authorship categories.
MAIN OUTCOME MEASURES
The main outcome measures were the website's average reading grade level, number of accessibility violations, multilingual availability, accessibility menu availability, complementary educational video availability, accessibility conformance level, and violation of the perceivable, operable, understandable, and robust (POUR) principles according to the WCAG 2.0.
RESULTS
A total of 32, 55, and 13 sites were affiliated with institutions, private practice, and other medical organizations, respectively. The overall mean reading grade was 11.8 ± 1.6, with higher reading levels observed in private practice websites compared with institutions and medical organizations combined (12.1 vs. 11.4; P = 0.03). Fewer private practice websites had multiple language options compared with institutional and medical organization websites combined (5.5% vs. 20.0%; P = 0.03). More private practice websites had accessibility menus than institutions and medical organizations combined (27.3% vs. 8.9%; P = 0.038). The overall mean number of WCAG 2.0 POUR principle violations was 17.1 ± 23.1 with no significant difference among groups. Eighty-five percent of websites violated the perceivable principle.
CONCLUSIONS
Available patient-oriented online information for cataract surgery may not be comprehensible to the general public. Readability and accessibility aspects should be considered when designing these resources.

目的
评估面向患者的白内障手术教育网站的网络可访问性和可读性。
设计
横断面电子调查。
参与者
专门提供白内障手术教育信息的网站。
方法
使用流行的搜索引擎进行“白内障手术”的匿名搜索。纳入排名前 100 的面向患者的白内障手术网站，并根据作者身份分为机构、私人诊所或医疗组织。使用 4 种标准化阅读水平公式评估每个网站的可读性。通过多语言可用性、可访问性菜单可用性、补充教育视频可用性以及符合和遵守 Web 内容可访问性指南 (WCAG) 2.0 来评估可访问性。使用标准 t 检验和卡方分析评估 3 种作者身份类别之间在可读性和可访问性方面差异的显著性。
主要观察指标
主要观察指标是网站的平均阅读水平、违反可访问性的次数、多语言可用性、可访问性菜单可用性、补充教育视频可用性、可访问性一致性水平以及根据 WCAG 2.0 违反可感知性、可操作性、可理解性和健壮性 (POUR) 原则的次数。
结果
分别有 32 个、55 个和 13 个网站隶属于机构、私人诊所和其他医疗组织。总体平均阅读水平为 11.8 ± 1.6，与机构和医疗组织联合相比，私人诊所网站的阅读水平更高（12.1 对 11.4；P = 0.03）。与机构和医疗组织联合相比，私人诊所网站提供多种语言选择的比例较低（5.5%对 20.0%；P = 0.03）。与机构和医疗组织联合相比，私人诊所网站提供可访问性菜单的比例更高（27.3%对 8.9%；P = 0.038）。总体而言，WCAG 2.0 POUR 原则违规的平均数量为 17.1 ± 23.1，各组之间无显著差异。85%的网站违反了可感知原则。
结论
现有的面向患者的白内障手术在线信息可能不容易被公众理解。在设计这些资源时，应考虑可读性和可访问性方面。
