Malpositioned IOL
Also written as: IOL — Malpositioned Intraocular Lens
Intraocular lens displacement from its intended location within the capsular bag or ciliary sulcus.
Full Definition
A malpositioned IOL refers to any deviation of an intraocular lens from its intended anatomical position following implantation. This complication can manifest as decentration (off-axis positioning), tilt (angular displacement), or complete dislocation into the vitreous cavity or anterior chamber. Causes include inadequate capsular support, zonular weakness, inappropriate IOL sizing, or trauma. Documentation must specify the type and degree of malposition, associated symptoms, and planned intervention. Surgical correction may involve IOL repositioning, exchange, or fixation techniques such as scleral suturing or iris fixation.
Usage
Usage note: Specify the direction and degree of malposition for accurate surgical planning.
