Abstract
Background: This study reports a case of silicone sponge intrusion as a late complication of scleral buckling surgery. Case presentation: A 57-year-old man underwent a silicone sponge scleral buckling surgery 19 years ago due to retinal detachment of his left eye. Visual acuity impairment of his left eye was noted. His best-corrected visual acuity (BCVA) was 20/80 (logMAR 0.6). Intraocular lens-capsular bag-capsular tension ring luxation with implant extrusion was observed in the inferior nasal quadrant. The patient underwent pars plana vitrectomy with retropupillary iris-claw lens implantation. His BCVA improved to 20/20. Conclusion: Although silicone sponge intrusion is a rare complication of scleral buckling procedures, it may lead to serious complications. The intruding sponge may be left intact unless there is a significant threat to the integrity of ocular structures. Manipulation of the encircling band or buckle does not necessarily alter the visual acuity or the status of the retina.
