March 16, 2026 updated by: Perfect Lens, LLC

A Prospective Study to Assess the Clinical and Refractive Outcomes of the Use of a Femtosecond Laser on an Implanted Intraocular Lens

This is a prospective non-randomized patient controlled single center study which is designed to evaluate the clinical outcomes of the treatment of an implanted intraocular lens using a low-energy femtosecond laser for refractive correction.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this research study is to evaluate the safety and efficacy of the treatment of an implanted intraocular lens with a device. The device employs a generic femtosecond laser used in numerous other ophthalmic procedures. The device uses low levels of energy from the femtosecond laser to correct spherical, cylindrical and sphero-cylindrical refractive error existing in an implanted intraocular lens. The refractive correction is effected through the treatment, which is employed at least 30 days after cataract surgery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Primary Endpoint - Change in mean manifest refraction spherical equivalent ("MRSE") (post- versus pre-treatment)
Time Frame: Between pre-treatment and 1 week post-treatment.
Change in mean manifest refraction spherical equivalent ("MRSE") post-treatment at 7-day visit versus pre-treatment.
Between pre-treatment and 1 week post-treatment.
Safety Endpoint - Primary Device Related Adverse Events (post- versus pre-treatment)

Between pre-treatment and 1 month and 3 months post-treatment.

Secondary Outcome Measures
