Ocular biometry in children and adolescent from age 4 to 17 years with intraocular lens power calculation in Sulaymaniyah city

Abstract

Background and objectives: Ocular biometry is an essential method to measures the anatomical dimensions of the eye in adult and children. The objective is to detect the ocular biometric changes and intraocular lens power calculation in children and teenagers (4 to 17) years. Methods: This hospital-based observational study included 208 participants (109 females and 99 males) distributed across three age groups (4 to 8, 9 to 12, 13 to 17) years, visiting Shahid Dr. Aso Teaching Eye Hospital in Sulaymaniyah governorate from November 2022 to July 2023. Information on axial length, anterior chamber depth, mean keratometry value, central corneal thickness, and intraocular lens power was collected and evaluated by the IOL Master 700 and Haigis formula. Results: The average age was 10.52 with a standard deviation of ± 3.31. In the three age groups, AL changed from 22.83 mm to 23.28 mm. Mean keratometry values ranged from 43.46 D to 43.20 D, and IOL power varied from 22.27 D to 21.33 D. Despite gender differences, only AL and IOL power changes were statistically significant (p values: 0.025 for AL, 0.00 for IOL). Conclusion: The optical ocular elements consistently align with changes in axial length, showing an increase as the child ages. This is accompanied by a decline in mean keratometry values, particularly between the ages of 4 to 8 years and a decrease in intraocular lens power. As the child matures, the variations in these parameters diminish.
