Purpose:

‏To evaluation of aphakic refraction technique for secondary intraocular lens power calculation in children

Methods:

‏33 eyes of children between 3-14 years old who had been underwent  Evaluation of aphakic refraction technique for secondary intraocular lens power calculation in children was obtained.the IOL power that would have achieved target refraction(2 diopter hyperopia for children between 3-4.5 years,1 diopter hyperopia for children between 4.5-6 years and emmetropia for children ≥6 years) was calculated retrospectively.an IOL difference was calculated by subtracting this target refraction from IOL power calculated by the 2 formulas using aphakic SE(lanchulev and leccisotti )

Results:

‏After surgery, 40% of eyes were within -1.00 to +1.00  diopters.and 66% were within -2.00 to +2.00 diopters ‏Lanchulev formula in all eyes (except one eye) and leccisotti formula in all eyes led to myopia(mean -4.3 diopter myopia for lanchulev and -8.70 diopter for leccisotti). ‏using data and with reduction the coefficient of lanchulev formula,we derived alternative formula that was comparable with conventional formulas (our formula:IOL power=aphakic

Conclusion:

although Based on previous studies in adults lanchulev formula can be applied to most eyes and leccisotti formula shows good performance in myopic eyes,but based on our study in children both formulas lead to significant postoperative myopia.but the new alternative formula reported in our study is comparable with conventional formulas in children and can be used when we can not use conventional formulas in children
