To report a case of anterior chamber intraocular lens (ACL) reposition with the haptic protruded into the subconjunctiva in a patient with a previous ACL implantation.

A 64-year-old man visited our clinic because of visual disturbance and discomfort in his right eye. Approximately 8 years earlier, he had cataract surgery and there was no visual improvement but eye discomfort. The haptic of the ACL protruded into the subconjunctiva at 11-1 o'clock. The visual acuity of the right eye was 0.2 and the intraocular pressure of the right eye was 27 mmHg. The ACL was repositioned because of low cell density (1222 cells/mm²). After 6 months, the visual acuity of the right eye was 0.3, best corrected visual acuity was 0.8, intraocular pressure was 12 mmHg and cell density was 838 cells/mm². There were no inflammation signs or complications.

Reinserting ACL when the haptic is protruding into the subconjunctiva could be a simple and safe method when a decrease in corneal endothelial cell density is present.
