The IntraOptics opacity lensmeter accurately measures nuclear cataract changes, showing lens density increases with age. This tool aids in monitoring cataract progression and serves as a clinical aid.

Area of Science:

  • Ophthalmology
  • Biomedical Engineering

Background:

  • Cataracts are a leading cause of vision impairment.
  • Accurate measurement of cataract progression is crucial for clinical management.

Purpose of the Study:

  • To evaluate the IntraOptics opacity lensmeter 701 for quantifying nuclear cataract density.
  • To assess the relationship between age and lens density in phakic eyes.

Main Methods:

  • Evaluated 589 eyes using the IntraOptics opacity lensmeter 701.
  • Analyzed data from 578 phakic eyes (average age 60.3) and 21 pseudophakic eyes.
  • Utilized regression models to determine the effect of age on lens density.

Main Results:

  • Developed an exponential model (Density = 6.2 x e(0.02 x Age)) with a correlation coefficient of 0.759.

  • Phakic eyes showed an average lens density of 22.09.
  • Pseudophakic eyes had an average density of 9.23.

    • Conclusions:

    • The IntraOptics opacity lensmeter is a rapid and accurate instrument for documenting nuclear cataract changes.
    • The lensmeter can be a valuable clinical tool for monitoring cataract progression.
    • It may serve as an objective "electronic" second opinion in cataract assessment.
