AIM:To investigate the safety and outcome of phacoemulsification and extracapsular cataract extraction (ECCE) technique for cataracts extraction in eyes with posterior capsule defect. METHODS:Totally 33 cataract cases(40 eyes) with posterior capsule defect were analyzed retrospectively. ECCE was performed in 12 eyes and phacoemulsification in 28 eyes. RESULTS:Posterior capsular rupture and vitreous prolapse:3 eyes(25%)in ECCE group and 3 eyes(11%)in phaco group(P<0.05).Postoperative visual acuities improved more than two lines:83%in ECCE group and 93%in Phaco group(P<0.05). CONCLUSION:Phacoemulsification technique is safe and has a better outcome than ECCE for cataracts in eyes with posterior polar cataract.Keeping a stable anterior chamber,no water separation and correct handling of the posterior pole cortex and posterior capsule are the key factors for successful operation during this phaco technique.
