Study summary

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.

Read the 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.

Study population

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

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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

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

Groups and cohorts

  • 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

Interventions

  • DeviceLIO ASQELIO TM monofocal QLIO130C

    Intraocular lens (IOL) implant. All patients will have been treated as per standard clinical practice.

What researchers measure

Primary outcomes

  1. Incidence of Posterior capsular opacity

    Incidence of PCO

    Time frame: 24 months after IOL implantation

  2. Intensity of Posterior capsular opacity

    Intensity of PCO determined using LOCSIII Classification

    Time frame: 24 months after IOL implantation

  3. Visual acuity

    Best corrected distance visual acuity in LogMAR units using the ETDRS chart

    Time frame: At least 24 months after IOL implantation

Secondary outcomes

  1. Refraction

    Residual refractive error in diopters determined objectively

    Time frame: At least 24 months after IOL implantation

  2. Incidence of Glistening

    Incidence of IOL glistening

    Time frame: At least 24 months after IOL implantation

  3. Intensity of Glistening

    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).

    Time frame: 24 months after IOL implantation
