OBJECTIVE: To examine the accuracy of the @entity2790 calculation by @entity6755 /T formula in pediatric @entity231 @entity1 , by means of the @entity2246 after the @entity231 surgery. MATERIAL AND METHOD: A retrospective review of pediatric @entity1 requiring @entity231 extraction with @entity2790 implantation, between January 2006 and December 2013 was performed. Post-operative spherical equivalent was compared with the predicted calculation value from pre-operative @entity6755 /T measurement, defined as @entity2246 ( @entity2246 ). RESULTS: 139 eyes from 106 @entity1 were studied. The median age of @entity1 at surgery was 4.56 years (IQR, 14). The two most common causes of @entity231 were @entity735 (25.9%), respectively. Primary @entity2790 ( @entity2790 ) implantation was performed in 87 (62.6%) eyes. The mean @entity2246 was -1.32  1.89 D (-7.78, 2.24). At one to three months after surgery, the mean @entity2246 of @entity2790 in bag and sulcus were -0.87 D and -2.02 D, respectively. In non-traumatic group, the mean @entity2246 of @entity2790 in bag and sulcus were -1.1 D and 2.28 D, respectively, whilst the traumatic group was -0.33 D and -1.16 D, respectively. Post-operative @entity2246 within   1 diopter was found in 30 eyes (37.97%) at one to three months of follow-ups. CONCLUSION: The majority of post-operative refraction was more myopic than the taigeted @entity2516 , which was calculated by @entity6755 /T formula. Aiming for a more hyperopic target and @entity2790 implantation in the bag would decrease the post-operative @entity2246 in the use of the @entity6755 /T formnula in pediatric @entity231 @entity1 .
