This video describes the stepwise management of dislocated intraocular lens (IOLs). It explains the pre-operative considerations and planning which goes into planning the surgery. It further discusses the management options one by one depending upon the amount of natural capsular support and type of dislocated IOL. The video also presents special situations such as with the bag dislocation, double dislocated IOLs, one lens in sulcus and another in the vitreous cavity and dislocated scleral fixated IOLs. The video will help the viewer to make informed decisions for management on a case to case basis and then proceed for surgery.


The video provides a stepwise solution to the multitude of situations viewers can face while managing patients with dislocated IOLs in everyday practice.

Video Transcript


Dislocated intraocular lenses require individualized management in each case. In this video, we will discuss the various management options for such cases in a variety of situations. IOL dislocation can be caused by either loss of capsular integrity or dislocation of the complete IOL Bag complex due to the loss of zonular integrity. From the point of timing of dislocation, it can either occur early, within a few days of surgery; intermediate, when it occurs a few days to weeks after the surgery; or late, when the IOL dislocates months to years after the primary surgery.

The etiology too varies according to the timing. Early dislocation occurs due to intraoperative events, such as misjudging the capsular support or inadvertent placement of the IOL through the posterior capsular tear by the surgeon. Intermediate dislocation may occur due to spontaneous rotation of the IOL away from the areas of capsular support. Late dislocation usually occurs due to loss of zonular support, which may occur over time due to inherent disorder, such as pseudoexfoliation or induced by external trauma.

In a patient with a dislocated IOL, management options include either observation or surgery. Surgical options can, again, be divided into either repositioning the same IOL, or in certain situations, an IOL exchange. Observation is only advised when there is a simple decentration of the IOL and the patient is comfortable with refractive correction and/or use of miotic agents. Observation may also be chosen if systemic and ocular factors limit further intervention or the patient declines consent.
