Cataract remains a prevalent cause of visual impairment among the elderly, significantly increasing the risk of falls due to compromised visual function. Cataract removal surgery has been established as a means to enhance visual acuity and balance control. The advent of novel technologies, such as accelerometers integrated into smartphones, provides an opportunity to assess static balance control. We compared static balance measurements obtained from accelerometer built-in smartphones before and after cataract removal surgery.
Our sample comprised 29 individuals diagnosed with bilateral cataracts scheduled for cataract removal surgery. We evaluated participants' visual acuity and recorded their body oscillations using the smartphone's embedded accelerometer during static balance maintenance, both with eyes open and closed, before and after surgery. We compared quantitative parameters of static balance evaluation at both time points.
A significant improvement in visual acuity following cataract removal surgery was observed. Moreover, under open-eye conditions, all quantitative parameters of static balance evaluation exhibited significant improvement, with only one parameter showing improvement under closed-eye conditions.
Inertial sensors integrated into smartphones serve as practical tools for monitoring changes in static balance control resulting from cataracts, as well as for evaluating balance recovery after lens extraction surgery.
白内障仍然是老年人视力损害的常见原因，由于视觉功能受损，显著增加了跌倒风险。白内障摘除手术已被确立为提高视力和平衡控制的一种手段。新技术的出现，如集成在智能手机中的加速度计，为评估静态平衡控制提供了机会。我们比较了白内障摘除手术前后通过内置加速度计的智能手机获得的静态平衡测量结果。
我们的样本包括29名被诊断为双侧白内障并计划进行白内障摘除手术的个体。我们评估了参与者的视力，并在手术前后，在睁眼和闭眼状态下，使用智能手机内置的加速度计在静态平衡维持期间记录他们的身体摆动。我们比较了两个时间点静态平衡评估的定量参数。
观察到白内障摘除手术后视力有显著改善。此外，在睁眼条件下，静态平衡评估的所有定量参数均有显著改善，而在闭眼条件下只有一个参数有所改善。
集成在智能手机中的惯性传感器是监测白内障引起的静态平衡控制变化以及评估晶状体摘除手术后平衡恢复情况的实用工具。
