High-intensity focused ultrasound (HIFU) is a noninvasive procedure commonly used for skin tightening. However, it has the potential to cause severe ocular complications^(1,2).

A 29-year-old female presented with complaints of "white spots" in her right eye's visual field following an eyelid HIFU application. Slit-lamp examination revealed four small lens opacities located outside the visual axis. Anterior segment optical coherence tomography confirmed focal opacities in the lens (Figure 1).

This case highlights the necessity for stringent ocular protection during HIFU procedures. Given the increasing popularity of HIFU for cosmetic applications, its risks may be underestimated⁽³⁾. Qualified practitioners must ensure patient safety by implementing appropriate protective measures.
