Eye study seeks best way to measure focus range
NCT ID NCT06767319
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 79 adults who already had a specific type of artificial lens implant (TECNIS monofocal or Eyhance IOL). The goal was to compare two methods for measuring depth of focus: using trial lenses versus a chart at different distances. No new treatment was given; the aim was to see which method gives more consistent results.
