Plain English summary of protocol

Background and study aims
To assess the safety and effectiveness of cataract surgery using the Light Adjustable Lens (LAL) using two doctors, co-managing for each patient. The surgeon will do the surgery and a medical provider will do light treatments to the LAL to further improve vision after surgery. Surgery and light treatments will be done in different locations. Light treatments will be done in a facility that is open access for patients of other surgeons.

Who can participate?
Patients that have cataracts, wanting the LAL and do not have any diseases of the macula or cornea.

What does the study involve?
Having cataract surgery and using the LAL as the IOL implant at the time of the cataract surgery. It will involve up to 5 follow-up light treatments to adjust the power of the LAL after surgery to further improve the patient's vision.

What are the possible benefits and risks of participating?
The benefits would include improved vision from correction of the cataract and improved vision from correction of refractive error (glasses) through adjustment of the power of the LAL after surgery. All surgery and testing are “standard of care” with no “study specific” surgery or tests performed. Risks are related to those of cataract surgery including vision loss and the need for additional surgery.

Where is the study run from?
It is run from the surgery center where cataract surgery is performed and the TCEC LASIK Center where the post-op light treatments are performed (USA)

When is the study starting and how long is it expected to run for?
July 2021 to January 2022

Study objectivesUsing a comanaged arrangement at an open access facility, use of the Light Adjustable Lens in cataract surgery is safe and efficacious.
Ethics approval(s)Ethics approval is not required given its retrospective chart review design, confirmed by Salus IRB.
Health condition(s) or problem(s) studiedUse of the Light Adjustable Lens in patients with cataracts and receiving cataract surgery
InterventionObservational retrospective case series chart review of a consecutive series of patients in a private practice setting between July 2021 and January 2022.
The visual acuities, manifest refractions, and adverse events were evaluated in the charts of patients that underwent cataract surgery using the light adjustable lens. Data was extracted from the patient's final postoperative visit sometime between 3 and 9 months postoperatively.
Intervention typeOther
Primary outcome measureCollected by retrospective chart review between 3 and 9 months postoperatively:
1. Uncorrected monocular and binocular distance
2. Near visual acuities
3. Safety
Secondary outcome measuresCollected by retrospective chart review between 3 and 9 months postoperatively:
1. Manifest refraction
