Most patients were visually asymptomatic, but those with decreased visual acuity (Stage 4) required Nd:YAG laser treatment to remove the AOM. These patients had improved visual acuity without recurrence of the AOM during the one-year follow-up period.Conclusion: AOMs can present and progress in four distinct stages with variable visual significance. AOMs may be safely and effectively treated with Nd:Yag laser. Occurrence of the membrane may be related to many factors, including high fibronectin content of this IOL. Additional studies are needed to identify incidence, etiology, and best management strategies.Keywords: anterior optic membrane, hydrophobic intraocular lens, fibronectin, YAG laser
