To discuss long-term changes of refractive status in children after congenital cataract intraocular lens ( lOL) implantation and analyze its related influence factors.METHODS: Seventy cases ( 110 eyes ) with congenital cataract from January 2013 to January 2014 in our hospital were selected, according to the age of patients, they were divided into group A (<2 years old), group B (2~6 years old) , group C ( 7 ~ 12 years old ) . They were all given cataract extraction combined with lOL implantation in congenital cataract. Corneal curvature, axial length, refractive status of three groups after operation were compared, the influence factors ocular axis changes were analyzed. RESULTS: There were no statistically significant differences in corneal curvature of groups A, B, and C after operation ( P>0. 05 );The differences had statistical significances of the corneal curvature of group A after surgery and 3mo after operation (P<0. 05), there were no significant differences of the corneal curvature of group B, group C after surgery and 3mo after operation (P>0. 05);the corneal curvature 3mo after operation of group A was significantly higher than that of groups B and C (P<0. 05), there were no significant differences in the corneal curvature between group B, and group C after 3mo ( P>0. 05 ); There were no statistical significances on axial length after operation in groups A, B, and C (P>0. 05);Ocular axial length difference of group A 3mo after surgery was significantly higher than that of groups B and C ( P < 0. 05 ), ocular axial length had no statistical difference of group B, group c 3mo after surgery ( P>0. 05). Refractive status of three groups after operation showed myopia moving trend, refractive change rate and refractive diopter of group A after operation was significantly higher than that of group B, group C, the difference was statistically significant (P<0. 05). CONCLUSlON: After congenital cataract extraction combined with lOL implantation, patients present myopia refractive state trend. Performance of children below 2 years old is significant. The main factor of myopia is axial growth.
