About this study

Official title: Refractive Outcome and Optimization of IOL-Constants After Implantation of the Precisight® Intraocular Lens.

The purpose of this study is to determine the refractive outcomes and optimize the clinical features of a new intraocular lens intended to treat the senile cataract.

Read the detailed description

InfiniteVision Optics has developed a new IOL system, the Precisight IOL. This IOL consists of a combination of two lenses: a base lens which is placed permanently into the capsular bag, and a front lens which sits on top of the base lens outside the capsular bag. The major advantage of this system is the adjustability of the primary IOL implantation which is done by front lens exchange. In case of either postoperative refractive adjustments or patient dissatisfaction with the visual performance, the front lens can be easily exchange by a less invasive surgery, avoiding a total IOL explantation. The implantation of the Precisight IOL is similar to the implantation of a traditional intraocular lens with no expected additional risk.

For all new IOLs, the IOL-constants are determined and provided by the manufacturer. They are calculated on the basis of eye models and clinical testing. In this study the biometric data of each patient's eye will be documented together with the implanted lens power and the postoperative stable refraction for calculation of the optimized IOL-constants.

In the present study, 125 subjects will be enrolled. Patients with a deviation from target refraction of more than 0.5 D spherical equivalent at the 2-3 month follow-up visit will undergo a secondary intervention for exchange of the front lens. These patients will be followed up for 1 year after front lens exchange.

Subjects will be screened during a pre-operative visit. Before the surgery visit, the subjected must have signed the Informed Consent Form.

After the surgery, patients will be followed up for one year. The visits will be scheduled at 1 day, 7-14 days, 2-3 months and 5-7 months and 1 year after surgery. Patients who underwent a surgery to exchange the front lens will be also followed up 1 day, 7-14 days, 2-3 months and 5-7 months and 1 year after the exchange surgery.

Investigator site staff will document the data in electronic Case Report Forms (eCRF). The data will be pseudonymized, i.e. only the year of birth and a code will be entered in the eCRF. Adverse events will be recorded in an eCRFs. Unexpected and serious adverse events are to be reported to the manufacturer.

Data cleaning will be done one month after last patient out and study report finished three months after last patient out. Subjects must be withdrawn from the study (i) at their own request, (ii) in case of intraoperative complication impacting the safety of the patient or (iii) in case of any postoperative complication if the continuation of the study has an impact on the safety of the patient. The study may terminate before completion if a high relative number of individual subject withdrawals due to the patient's requests and/or clinically relevant complications are observed. The IRB will be informed in due course accordingly.

The findings of this study will be published by the investigators in a scientific journal and presented at scientific meetings.

What is being measured

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

  1. Change of the subjective refraction

    The evolution of subjective refraction will be assessed after Precisight implantation.

    Measured: 2 to 3 months, 5 to 7 months and 1 year after the investigational device implantation

Secondary outcomes (5)
  1. Best-corrected distance visual acuity

    Measured: 1 day, 7 to 14 days, 2 to 3 months, 5 to 7 months and 1 year after the investigational device implantation

  2. Introcular lens (IOL) decentration and tilt

    Measured: day of surgery, 2 to 3 months, 5 to 7 months and 1 year after the investigational device implantation

  3. Anterior chamber depth

    Measured: pre-operative, 2 to 3 months, 5 to 7 months and 1 year after the investigational device implantation

  4. Adverse events

    Measured: All follow up period (1 year)

  5. Assessment of investigator regarding handling and achievement of target refraction

    The investigator shall answer a questionnaire.

    Measured: Six months after investigational device implantation

Questions about this trial

What is this clinical trial studying?

A study testing Intraocular implant of the Precisight in people with Cataract Senile, run by InfiniteVision Optics at 1 site in Philippines.

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 5 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 1 Mar 2019. 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 Philippines. 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?

Results are not available in the source record.

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?

Change of the subjective refraction (time frame: 2 to 3 months, 5 to 7 months and 1 year after the investigational device implantation). 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 1 Mar 2019.
