KEY TAKEAWAY POINTS

Lens epithelial cell on-growth (LECOG) is one of the phenomena associated with capsular bag biocompatibility that has been reported in many IOLs with different types of biomaterials.

The chemical and physical properties of IOL biomaterial is considered to play an important role in the LECOG’s etiology with other contributing factors.

LECOG is usually self-limited without impact on patient’s vision and the need of intervention. However, in severe and persistent cases, Nd:YAG laser treatment may be safely applied to restore patients’ vision.
