Safety and Efficacy of the Hydrophobic Intraocular Lens Asqelio Monofocal With Biaspheric Design

October 4, 2024 updated by: AST Products, Inc.
The goal of this observational study is to learn about the Asqelio monofocal intraocular lens (IOL) model QLIO130C in patients undergoing cataract surgery. The aim of the study is to evaluate the lens implementation safety and efficacy after at least 24 months.

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

This is a retro-prospective, post-marketing observational study of a CE-marked medical device. The efficacy and safety of the Asqelio monofocal intraocular lens (IOL) model QLIO130C from AST Products, Inc, Billerica, USA, will be studied in patients implanted according to standard clinical practice. Twelve-month follow-up data will be collected from the medical records of the patients included in the study, and after 24 months they will be scheduled for a review.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult subjects undergoing cataract surgery, implanted with ASQELIO monofocal model QLIO130C, and with a follow-up of more than 24 months.

Description

Inclusion Criteria:

  • Subjects 22 years of age or older undergoing cataract surgery in at least 1 eye and implanted with ASQELIO monofocal model QLIO130C.
  • Subjects for whom postoperative emmetropia (±0.5 D spherical equivalent) was planned.

Exclusion Criteria:

  • Any pathology that reduces the potential Visual Acuity (VA) with its best correction beyond 0.30 logMAR.
  • Previous corneal surgery.
  • Rubella or surgery due to traumatic cataract.
  • Ocular trauma or refractive surgery.
  • Any other ocular or systemic condition that, in the opinion of the investigator, should exclude the subject from the study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Patients undergoing routine clinical practice with ASQELIOTM monofocal LIO model QLIO130C.
Data will be extracted retrospectively from their medical records and prospectively in a single follow-up visit. All procedures performed are according to standard clinical practice.
Device: LIO ASQELIO TM monofocal QLIO130C
Intraocular lens (IOL) implant. All patients will have been treated as per standard clinical practice.

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
Time Frame
Incidence of Posterior capsular opacity
Time Frame: 24 months after IOL implantation
Incidence of PCO
24 months after IOL implantation
Intensity of Posterior capsular opacity
Time Frame: 24 months after IOL implantation
Intensity of PCO determined using LOCSIII Classification
24 months after IOL implantation
Visual acuity
Time Frame: At least 24 months after IOL implantation
Best corrected distance visual acuity in LogMAR units using the ETDRS chart
At least 24 months after IOL implantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Refraction
Time Frame: At least 24 months after IOL implantation
Residual refractive error in diopters determined objectively
At least 24 months after IOL implantation
Incidence of Glistening
Time Frame: At least 24 months after IOL implantation
Incidence of IOL glistening
At least 24 months after IOL implantation
Intensity of Glistening
Time Frame: 24 months after IOL implantation
Intensity of IOL glistening. It will be evaluated by examining the center of the IOL optical zone with the pupil dilated using a slit lamp. The intensity of glistening will be graded as the number of glistening in the central region according to the following scale: 0 = absent, 1 = traceable (countable vacuoles), 2=moderate (low density of countless vacuoles), and 3=severe (high density of countless vacuoles).
24 months after IOL implantation

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
