Purpose
Study evaluates changes in Biometry parameters post Clareon IOL implant in short (axial length < 22.5mm) and long eyes (axial length > 24.5mm).
Setting
Department of Cataract and Refractive surgery in a tertiary care centre
Methods
Single-center study on post-cataract Clareon IOL patients with axial length < 22.5mm or > 24.5mm. Pre-op assessments: slit lamp exam, optical biometry with IOLMaster 700, refraction, and visual acuity. ACD, VCD, Axial length measured at 1 week, 1 month, and 3 months post-op in 30 eyes per group.
Results
Short eyes group (mean axial length: 22.14 ± 0.36 mm) had ACD measurements at 1 week, 1 month, and 3 months: 4.30 ± 0.34mm, 4.38 ± 0.30 mm, 4.38 ± 0.31 mm. Long eyes group (mean axial length: 26.20 ± 1.60 mm) had corresponding ACD measurements: 4.85 ± 0.28mm, 4.78 ± 0.28 mm, 4.81 ± 0.27 mm. Axial length decreased by 0.07 ± 0.01mm following cataract surgery both in short and long eyes (p<0.01). VCD measurement at baseline and 1week showed increase by 2.03 ± .06 95%CI ( 2.15 2.43) in Short eyes and 2.07 ± .05 95%CI (1.96, 2.17) in long eyes, and remain stable over 3 month follow-up period.
Conclusions
The ACD remained stable following implant of Clareon IOL over 3 months of follow-up period indicating axial stability of IOL. VCD showed an increase following cataract surgery and then remain stable over 3 month period.
