Area of Science:

  • Ophthalmology
  • Biometry
  • Medical Devices

Background:

  • Accurate ocular measurements are crucial for refractive error correction and intraocular lens power calculation.
  • Optical and ultrasound biometry are common methods for obtaining these measurements.
  • A comprehensive comparison of various devices using big data is needed.

Purpose of the Study:

  • To systematically compare and rank ocular measurements obtained by optical and ultrasound biometers.
  • To identify differences in measurements like axial length, keratometry, and corneal thickness.
  • To provide evidence-based rankings for biometry devices.

Main Methods:

  • A systematic literature search was conducted in PubMed, Embase, Cochrane Library, and US trial registry up to October 22nd, 2020.
  • Included comparative studies reporting axial length (AL), keratometry (Ks, Km), astigmatism (AST), anterior chamber depth (ACD), central corneal thickness (CCT), corneal diameter (CD), and lens thickness (LT).
  • A network-based big data analysis was performed using STATA version 13.1.

Main Results:

  • Data from 129 studies involving 17,181 eyes were analyzed, comparing 12 optical and 2 ultrasound biometers.
  • Contact ultrasound biometry showed statistically significant differences in AL and ACD compared to optical biometers.
  • Significant differences were noted for Ks, Km, and CD between Pentacam AXL and IOLMaster devices, and for CCT among several optical biometers.

Conclusions:

  • Contact ultrasound biometry tends to provide lower values for axial length and anterior chamber depth compared to optical biometers.
  • Pentacam AXL demonstrated the lowest values for keratometry and corneal diameter.
  • The OA-2000 yielded the smallest central corneal thickness measurements.
