Comparing the accuracy of different intraocular lenses power calculation formulas in children with short axial length

Background Improved techniques have increased the use of intraocular lenses (IOL) in children, but predicting accurate lens power is hard due to eye growth and measurement challenges. Adult formulas are unreliable for kids, and the best calculation method is still debated. Aim Comparing the precision of various IOL power calculation formulae in children with congenital cataract and short axial length (AL). Patients and methods This is a prospective interventional comparative study. A research was conducted on 30 eyes of 17 children, four cases were unilateral and 13 cases were bilateral, children were divided in to three groups according to IOL calculation formula that had been used: group 1: Haigis formula had been used for IOL power calculation for 10 pediatric eyes, group 2: sanders-retzlaff-kraff theoretical (SRKT) formula had been used for IOL power calculation for 10 pediatric eyes and group 3: Hoffer Q formula had been used for IOL power calculation for 10 pediatric eyes. Results Substantial disparities were identified in AL, IOL power, and predicted errors among the three formulas, between SRKT and the others, keratometry, corneal diameter, postoperative refraction, and reduction values showed no significant differences. Conclusions Numerous distinct problems hinder the application of IOLs in children. The SRKT formula was the least predicted error. We found that SRKT was the most predictive formula for AL less than or equal to 21 mm.
