AIM:To investigate the treatment of the congenital malformations of small eyeball and small palpebral fissure.·METHODS:Eleven eyes(11 cases) of congenital malformation who accepted the surgical treatment including conjunctival flap covering the entire cornea,outer canthal expanding,and conjunctival sac forming were retrospective analyzed.·RESULTS:In 11 cases,9 cases were able to successfully wear the pre-selected artificial eyes after 4 weeks,the conjunctival flap failed to heal in 2 cases,but after 6 weeks of treatment,they healed to wear artificial eyes.During the follow-up of 2-21 months,4 cases were replaced with larger models of artificial eyes.All cases could easily wear artificial eyes without palpebral fissure retraction,the corneal coverage was intact,no kenspeckle irritation with artificial eyes,and the appearance were obviously improved.·CONCLUSION:The surgical method of covering cornea,expanding outer canthus,and conjunctival sac forming,has the advantages of satisfactory appearance,minor trauma,fewer complications,less pain and low cost,and is worthy promotion.
