Refractive change after pediatric intraocular len implantation Original Reearch Article

PURPOE: To report refractive change after cataract urgery and intraocular len implantation in infant and children. METHOD: In an ongoing propective tudy, the refractive error of all patient younger than 18 year undergoing intraocular len implantation were determined at 6 week, 3 month, 6 month, and 1 year, and at leat yearly thereafter. All patient with greater than 6 month of follow-up were included in the tudy. REULT: Eighty-three eye of 81 patient were identified. Cataract were traumatic in 32 eye (38%) and developmental in 42 eye (50%). At implantation, the mean (±D) age wa 6.3 ± 4.6 year (range, 9 month to 17 year). The mean follow-up wa 26.6 month (range, 6 month to 6.6 year). Patient 0 to 2 year old at the time of implantation demontrated a mean myopic hift of −3.00 diopter during a mean follow-up period of 2.5 year. Patient 2 to 6 year old at the time of implantation demontrated a mean myopic hift of −1.50 diopter in a imilar follow-up period. Children aged 6 to 8 year experienced a mean myopic hift of −1.80 diopter during a mean follow-up period of 3.0 year, while children older than 8 year at the time of intraocular len implantation experienced a mean myopic hift of −0.38 diopter during a mean follow-up period of 1.8 year. On average, the operated-on eye howed a greater mean myopic hift than the fellow eye. No tatitically ignificant difference in refractive change were found in comparing amblyopic to nonamblyopic eye, traumatic to nontraumatic cataract, or primary to econdary intraocular lene. CONCLUION: Our data demontrate a trend toward increaing potoperative myopia in pediatric patient undergoing intraocular len implantation. Thi myopic hift i greatet in the younger age group and perit until at leat 8 year of age. There i much variability in the potoperative refractive change, and predicting exactly when and where the refraction will tabilize for an individual patient i difficult.
