Case summary: 64 and 57-year-old woman consulted with us because of blurred vision in the pseudophakic eye at four or five years after cataract surgery. On slit-lamp examination, remnant cortex, multiple cells and posterior capsule distension was found. The adherence of the capsulorhexis margin and optic of intraocular lens was confirmed with optical coherence tomography. After Nd:YAG laser posterior capsulotomy, the visual acuity of patients was improved.

Conclusion: The operator should give attention to the cortex removal during phacoemulsification to prevent capsular block syndrome. Optical coherence tomography can be helpful to diagnose capsular block syndrome.
