Data Collection After Intensity IOL Implantations

January 14, 2024 updated by: Hanita Lenses

Intensity Lenses Post Operation Standard of Care Visits - Data Collection.

Hanita Lenses new Intensity IOL and Intensity Toric were been designed to have very high efficiency of light leading to a high MTF, wide focal ranges of far, intermediate and near vision and minimal loss of light energy. The main purpose of this study is to collect existing post-operative data based on standard of care follow up visits at the clinic.

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

Different multifocal intraocular lens (MIOL) designs have been used for more than 25 years1. Unlike conventional mono focal intraocular lenses (IOLs), which bend light to a single focus point on the retina, MIOLs are designed to help patients to see at varying distances using different points of focus2. MIOLs used in clinical practice were either refractive initially, or later diffractive in their optical design. Refractive MIOLs incorporate a lens optic with different optical powers in different parts of the lens, while diffractive MIOLs use diffractive steps on the lens to distribute light rays into two or more principal foci. Irrespective of the design type, however, all MIOLs involve some form of optical compromise and a process of neuroadaptation for the patient.

Intensity SL intraocular lenses (IOLs) represent the latest in premium lens technology. Intensity SL lenses provide clear vision at all distances - from near to far - thus offering the best chance of true spectacle independence.

Despite the promising results obtained with the latest generation of MIOLs, many surgeons remain reluctant to implant these lenses. Visual symptoms such as glare and haloes, reduced contrast sensitivity and night vision problems are all known complications of multifocal implants and have served to hamper wider acceptance of these IOLs4.

Hanita Lenses new Intensity IOL and Intensity Toric were been designed to have very high efficiency of light leading to a high MTF, wide focal ranges of far, intermediate and near vision and minimal loss of light energy. The main purpose of this study is to collect existing post-operative data based on standard of care follow up visits at the clinic.

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

Men and women that had implantation with Hanita Intensity IOL or Intensity Toric Lenses in the clinic participating in the study. The patients that suffered from cataract and operated with implantation of Hanita Intensity MIOL or Intensity Toric MIOL in the clinic participating in the study.

Description

Inclusion Criteria:

  • Patient over the age of 18
  • Patient who underwent bilateral implantations with Hanita Lenses Intensity IOL

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
The aim of this study is to evaluate performance of Hanita Lenses Intensity SL IOL.
Time Frame: 1-3 months
Performance of the IOL will be evaluated by assessing the defocus Curve and visual acuity for far, intermediate and near distance after Intensity SL IOL implantation.
1-3 months

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
The second aim of this study is to evaluate the visual phenomena post-operation.
Time Frame: 1-3 months
Visual phenomena will be evaluated by asking the patients about halos ang glares
1-3 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 13, 2023

Primary Completion (Actual)

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.
