title: Assessment of midperipheral anterior chamber depth in patient with posterior chamber phakic intraocular lens.
abstract: We describe a patient who required surgical explantation of a phakic intraocular lens (pIOL) as a result of mechanical angle closure despite the absence of standard preoperative risk factors. An assessment of the patient's records suggested peripheral anterior chamber depth (ACD) values considerably shallower than the central ACD measurement. Subsequently, the midperipheral values of all patients having pIOL implantation at our practice were reviewed to provide potential baseline measurements for comparison against the values of the explanted pIOL eyes. Assessment of midperipheral anterior chamber anatomy may be advantageous in the evaluation of patients for pIOL surgery.
