About this study

Official title: Early Feasibility Study to Evaluate the Safety and Effectiveness of the AccuraSee for Secondary Implantation in the Capsular Bag to Correct Residual Refractive Errors of Previous Cataract Surgery

To determine if the intraocular pseudophakic contact lens (IOPCL), referred to as the AccuraSee, corrects residual refractive errors after cataract surgery using a plus powered lens in subjects with ocular pathology previously implanted with a Bausch and Lomb LI61AO or LI61SE monofocal posterior chamber intraocular lens (PCIOL) and to confirm its positional stability and adherence relative to the PCIOL.

Read the detailed description

This will be a 12-month study in which a maximum of 10 pseudophakic patients from three clinical sites will be enrolled. All enrolled subjects will receive an AccuraSee IOPCL with +3.0D add to correct residual refractive errors identified after cataract surgery.

The primary objective of this study is to determine the stability of the AccuraSee IOPCL to successfully adhere to a pseudophakic intraocular lens (PCIOL) without rotation or slippage.

The secondary objective of this study is to determine if the AccuraSee IOPCL can successfully correct refractive errors in subjects previously implanted with a Bausch and Lomb LI61AO and LI61SE monofocal intraocular lens.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AccuraSee IOPCL with +3.0D addDevice

    The IOPCL (intraocular pseudophakic contact lens) consists of a 4.5mm diameter optic. All subjects will receive a +3.0 power regardless of diopter power based on IOL Master. This IOPCL will be coupled to a Bausch and Lomb Model LI61SE or LI61AO intraocular lens to correct residual refractive errors after cataract surgery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Subjects With Stable Manifest Refraction Spherical Equivalent (MRSE)

    Proportion of subjects (≥ 50%) able to achieve MRSE stability within ±0.5D within two consecutive postoperative visits at 1 month or later visits.

    Measured: Assessed all postoperative consecutive visit pairings beginning with 1 month visit (1 month to 4 months; 4 months to 1 year); reported for "Postoperative period between 1 month and 1 year"

  2. Subjects With Successful Delivery of AccuraSee IOPCL

    Successful delivery of the AccuraSee IOPCL is defined as: 1) No capsular tear; 2) Visualized centration between the PCIOL and the IOPCL; 3) No visible damage to either the PCIOL or the IOPCL; and 4) Uniform leaflet coverage of all IOPCL haptic tabs

    Measured: 7-14 days visit

  3. Long Term Adherence and Positional Stability: Number of Participants With Greater or Less Than +/- 10 Microns Change in Gap Between the Pseudophakic Intraocular Lens and AccuraSee Intraocular Pseudophakic Contact Lens

    Safety Endpoint: Minimal change in uniformity of the gap between the pseudophakic intraocular lens (PCIOL) and AccuraSee intraocular pseudophakic contact lens (IOPCL), between 30-60 days and 120-180 days, as determined by ultrasound biomicroscopy (UBM) measurements. Minimal change is defined as +/- 10 microns.

    Measured: Assessed at 30-60 days visit and 120-180 days visit, 120-180 days visit reported

Questions about this trial

What is this clinical trial studying?

A study testing AccuraSee IOPCL with +3.0D add in people with Refractive Errors, run by OnPoint Vision Inc at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Apr 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Subjects With Stable Manifest Refraction Spherical Equivalent (MRSE) (time frame: Assessed all postoperative consecutive visit pairings beginning with 1 month visit (1 month to 4 months; 4 months to 1 year); reported for "Postoperative period between 1 month and 1 year"). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Apr 2024.
