NCT06260852 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 80

Last updated 2024-03-07

No results posted yet for this study

Summary

The primary objective of this study is to identify how many focal points and at which distances are necessary for reliable visual curve formation and area of the curve (AoC) calculation using mathematical models and comparing the results to measurements acquired from participants that underwent uncomplicated pseudophakic presbyopia surgery.

Conditions

  • Presbyopia
  • Pseudophakia
  • Cataract
  • Refractive Errors

Interventions
