Inadvertent cyclodialysis cleft and annular ciliochoroidal detachment after hyperopic phakic intraocular lens implantation and prophylactic surgical iridectomy.

UNLABELLED: We present the case of a 26-year-old man with severe early hypotony after implantation of the Implantable Collamer Lens phakic intraocular lens (pIOL) in the left eye for hyperopia. To our knowledge, this is the first documented case of cyclodialysis cleft and secondary annular ciliochoroidal detachment after implantation of a pIOL, presumably provoked by a straightforward prophylactic surgical iridectomy. The initial diagnosis was determined using swept-source Fourier-domain anterior segment optical coherence tomography as gonioscopy and ultrasound biomicroscopy did not reveal the cleft. Conservative treatment was not effective. Argon laser photocoagulation resolved the problem.
