A case of delayed recurrent hyphema following Implantable Collamer Lens (ICL) surgery.

PURPOSE: To present a case of delayed recurrent hyphema following toric ICL implantation.

OBSERVATIONS: This case reports a 24-year-old Asian female who presented with sudden decrease in vision in the right eye, accompanied by recurrent massive anterior chamber hemorrhage, six months after bilateral implantation of toric ICL with central holes for myopia correction. Despite initial conservative treatment with immobilization and intraocular pressure (IOP)-lowering medication at another hospital, the hyphema persisted. At our hospital, her corrected visual acuity (CDVA) in the right eye was counting fingers (CF) at 50 cm, with visible blood clots and hyphema in the anterior chamber, and an IOP of 40 mmHg. Ultrabiomicroscopy (UBM) indicated a large amount of hyphema in the anterior chamber. Initially, the patient was treated with a combination of three IOP-lowering medications: brimonidine eye drops, brinzolamide eye drops, and timolol eye drops, but the condition recurred. Two weeks later, we performed an anterior chamber hyphema evacuation and ICL removal surgery in the right eye. Postoperatively, the patient's IOP stabilized and her vision gradually recovered. One month after the surgery, a follow-up examination showed a CDVA of LogMAR 0.6 in the affected eye.

CONCLUSION AND

IMPORTANCE

This case report is essential for characterizing a rare and serious complication following toric ICL implantation, highlighting the importance of close monitoring and timely intervention.
