Real-time Precision in Lens Subluxation Surgery Guided by i-SS-OCT

A 65-year-old male presented with lens subluxation following ocular trauma. Preoperative assessment raised concerns about capsular integrity and instability. During surgery under the guidance of intraoperative SS-OCT (FOcean, Towardpi), lens subluxation (fig.1) was confirmed with partial separation of the posterior capsule and a small amount of vitreous entering into anterior chamber (fig.2).

After phacoemulsification, viscoelastic was gently injected into the capsular bag to distend the capsule, allowing thorough inspection of capsular integrity under iOCT (fig.3).

Under continuous iOCT monitoring, a capsular tension ring (CTR) was gently inserted clockwise into the capsular bag, effectively redistributing zonular tension and restoring capsular stability (fig.4).

With the bag now secured, the intraocular lens (IOL) was smoothly implanted. Intraoperative measurement enabled the assessment of IOL position and centration (fig.5).
