To explore the nyopic shift after cataract extrac tion(ECCE ) with intraocular lens implantation (IOL． ) during childhood．2l children (24 eyes) with ECCE+0L are retrospectively analyzed,and were divided into two groups according to the age． The initial and last postoperative refractive errors were compared． The mean myopic shift was -0.89±0.40 (3～5 years group ) and -0.97± 0.l8 (6～ l0 years N) The difference between two groups was not significantly different(t=0.2l, P>0.05 ) ．The myopic shift was less than l.5re in 91.6W of the w． 83.32 of the eyes achieved a visual acuity of 0.5 or better in their pseudosphakic eyes． Undercorrecting most children 3 to 10 years of ag e by 1.00D from the IOL power predicted to achieve emmtropia．
