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 appliedto restore patients’ vision.
