AI Article Synopsis

  • The study evaluated the effectiveness of three devices (OA-2000, Anterion, and IOLMaster 500) in measuring axial length in cataract patients, focusing on acquisition rates and measurement agreement.
  • Out of 298 eyes, the OA-2000 and Anterion achieved higher measurement success rates (96.64% and 94.30%) compared to the IOLMaster 500 (82.55%), with significant differences noted.
  • All three devices showed good agreement in their measurements, despite the IOLMaster 500 having a higher failure rate with patients having severe cataract conditions.

Article Abstract

Purpose: To assess the acquisition rate and agreement of axial length (AL) measurements with the OA-2000, Anterion, and IOLMaster 500 in cataractous patients.

Methods: In total, 298 eyes of 191 cataractous patients were enrolled and scanned with the three devices in random order. The success rate of AL measurements per device was calculated and a chi-square test was utilized to identify the differences in acquisition rate between the three devices. Logistic regression analysis was applied to evaluate the association of different cataract types and severity with the AL measurement acquisition rate. Bland-Altman plots were mapped to appraise the agreement of AL values.

Results: AL measurements were successfully achieved in 288 eyes (96.64%) with the OA-2000, in 282 eyes (94.30%) with the Anteiron, and in 246 eyes (82.55%) with the IOLMaster 500. Significant differences in the acquisition rate were found between either of the SS-OCT devices and IOLMaster 500 by chi-square analysis (P < 0.001). No significant difference was noted between OA-2000 and Anterion. Increasing severity of posterior subcapsular cataract was associated with a higher failure rate with the IOLMaster 500. Bland-Altman analysis identified good agreement between the three biometers with narrow 95% limits of agreement.

Conclusions: The OA-2000 and Anterion showed similarly higher acquisition rate of AL measurements than IOLMaster 500 in cataractous patients. Good agreement for AL values was found between the three biometers in cataractous patients.
