BACKGROUND AND OBJECTIVE: Peripheral defocus lenses (PDLs) have emerged as an effective therapeutic strategy to slow the progression of childhood and adolescent myopia. However, achieving optimal centration in pediatric patients can be challenging, and individual facial and postural characteristics must be carefully considered to ensure appropiate fitting. The primary objective of this study was to quantify PDL decentration as an undesirable effect during myopia management in children and adolescents undergoing concurrent atropine treatment.
MATERIALS AND METHODS: The distance between the pupil center and the optical center of the lens was measured in millimeters using a conventional millimeter ruler in primary gaze. Five PDL models were evaluated across the study cohort.
RESULTS: A total of 69 participants were included (mean age: 12.5 years; range 7-17). The mean spherical equivalent was -2.9 D (range: -0.25 to -8.50). Mean axial length was 24.59 mm (range: 22.96-27.02), and mean pupil diameter was 5.55 mm (range: 4-7.21). Mean decentration values were: inferior 2.26 mm; superior 0.13 mm; nasal 0.36 mm, and temporal 0.47 mm. Decentrations > 1 mm were observed in 76% of patients, > 2 mm in 50.7%, and > 3 mm in 33.3%.
CONCLUSIONS: In this cohort, PDL decentration exceeding 3 mm occurred in approximately one-third of pediatric myopic patients. These findings underscore the need for individualized frame selection and meticulous fitting to ensure accurate optical centration relative to the pupillary axis.
