·AIM:To investigate the effect of phacoemulification on unique eye cataract.·METHODS:Forty-four patients with unique eye cataract underwent phacoemulsification.The preoperative visual acuity(VA)and postoperative VA were recorded.Intraoperative and postoperative complications were observed.Following up time was form 3 to 12 months.·RESULTS:Postoperative VA raised at different degrees:corrected VA<0.1 in 2 eye(4.5%),0.1-0.25 in 8 eyes(18.2%),0.3-0.5 in 18 eyes(40.9%)and 0.6-1.0 in 16 eyes(36.4%).The best-corrected VA better than 0.3 accounted for 77.3%,and the rate of VA larger than 0.05 was 95.5%.After operation,corneal endothelial edema were in 5 eyes(11.4%),and after cataract in 2 eyes(4.5%)·CONCLUSION:Eye condition of unique eye cataract patients is changeable.Individual operation plan should be settled according to specific circumstance.Phacoemulsification and intraocular lens implantation is safe and effective for unique eye cataract.·
