title: Hyperopic shift with posterior bowing of a Collamer posterior chamber intraocular lens.
abstract: Two patients developed a hyperopic shift following uneventful phacoemulsification with implantation of a Collamer plate-haptic intraocular lens (Staar Surgical) in the capsular bag. Posterior bowing of the IOL was corrected by IOL exchange, achieving near emmetropia.
