Comparison of ocular biometry parameters between IOL Master and applanation A-scan in eyes with short, medium, long, and very long axial lengths
Aim: The aim of this study is to compare the ocular biometric parameters between intraocular lens (IOL) master and applanation A-scan in eyes with different axial lengths (ALs).

| description | Aim: The aim of this study is to compare the ocular biometric parameters between intraocular lens (IOL) master and applanation A-scan in eyes with different axial lengths (ALs).
Materials and Methods: A cross-sectional observational study was conducted 211 patients scheduled for cataract surgery at a tertiary care eye hospital. AL and anterior chamber depth (ACD) measurements were obtained both by IOL master and applanation A-scan under standard operating conditions and analyzed.
Results: The study sample comprised 211 eyes of 211 patients. Mean age of patients was 60.04 ± 7.90 years (range 40–84 years), 81% were male and 19% were female. Eyes were divided into four groups depending on their AL measurements as extremely long> 27.0 mm, long 25.0–27.0 mm, medium 22.0–25.0 mm, short <22.0 mm. The ALs measured by IOL master was significantly higher than those measured by A-scan (P < 0.001). Mean ACD with both methods was 3.23 ± 0.45 and 3.20 ± 0.46, respectively. In the subgroup analysis, there was good agreement between AL and ACD between IOL master and ultrasound A-scan in extremely long, long, medium, and short eyes.
Conclusion: AL and ACD showed good agreement between IOL master and applanation A-scan measurements at all range of ALs. |
