AIM: To investigate the surgical technique and clinical efficacy of phacoemulsification combined with intraocular lens implantation in cataract with microcoria.

METHODS: In 35 cases(43 eyes)of microcoria cataract, pupilloplasty were aided by viscoelastics or pulling from papillary collar. Continuous curvilinear capsulorhexis, phacoemulsification, and intraocular lens implantation were performed in all of the patients.

RESULTS: During the follow up of 5 to 12 months, 38 eyes(88%)got improved visual acuity, and it's better than 0.5 in 26 eyes(60%). The pupils of all patients remained circular or close circular with lightly expanded in some patients, without dislocation of intraocular lens. Main complications included corneal edema, fibrous exudates in anterior chamber, and rupture of posterior capsule.

CONCLUSION: Despite the complexity,phaco-emulsification is still an efficacy technique for treatment of cataract with microcoria.
