Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how much an artificial lens (implanted during cataract surgery) tilts or shifts out of place. Researchers will use a special camera to take detailed images of the lens in about 80 adults who had surgery at least three months ago. The goal is to gather information to help improve future lens designs and surgical outcomes.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

As only one eye per subject will be enrolled in the study based on the eligibility criteria, up to approximately 80 subjects (40 by site) will be enrolled to obtain data on approximately 72 subjects (36 per site) to account for approximately 10% screen failure rate. All efforts will be made to enroll approximately 36 subjects per pre-study IOL group (i.e. 18 per site per pre-study IOL type). Approximately in total 36 subjects (18 per site) will be examined for each of the following two pre-study IOL groups. * Group 1: TECNIS refractive non-toric IOL models * Group 2: TECNIS diffractive non-toric IOL models

Ages
