AIM: To investigate the safety and efficacy of phacoemulsification in the treatment of special types of cataract.

RESULTS:Of the 73 cases(84 eyes)for the treatment of special types of cataract, simple phacoemulsification in 27 cases 28 eyes; posterior chamber intraocular lens implantation in 52 eyes; anterior chamber intraocular lens implantation in 4 eyes; average intraocular pressure at postoperative 1 month was 12.72±2.63mmHg, the off-blind rate was 99%, off-disability rate was 96%; complication rate was 4%.

CONCLUSION: The surgery for special type of cataract is difficulty, small incision phacoemulsification and retained posterior capsule combined intraocular lens implantation is the ideal surgical removal for special type of cataract.
