Study Description

Brief Summary

The objective of this investigator initiated study (IIT-001) is to obtain data on clinical methods which can be used during the examination of patients desiring binocular custom vision with the Light Adjustable Lens (LAL). An analysis of the collected data will be performed to determine whether these clinical assessments can be used by doctors to enhance their patient's clinical outcome.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Bilateral implantation of light adjustable intraocular lens and subsequent adjustment to binocular custom vision
