IOL Experience

Experience IOL vision prior to implantation.

A person’s conscious experience cannot be captured by reductive analysis.

Prof. Thomas Nagel, philosopher

No one can tell for sure how a person perceives the world through their eyes. Except the person themselves. No ophthalmologist can predict 100 % what the vision of a person with their artificial lens will be. Except with RALV®.

Full focus on the patient

  • RALV is a revolutionary modified patient selection solution prior to refractive lens exchange.
  • RALV is the trial vision test for the selected IOL.
  • RALV is the missing link between preoperatively predicted and postoperatively achieved vision.
  • Before surgery, RALV provides an answer to the question of:

What will my vision with the artificial lens be after the refractive lens exchange?

A masterpiece of optics at the core

The smart design of the RALV® hardware conceals an ingenious masterpiece of optics. With individually equipped IOL shuttles. Controlled by the RALV app. RALV is no virtual simulator, but real vision through a genuine IOL!

RALV® stands for Real Artificial Lens Vision. RALV is a product of DEZIMAL GmbH.

What is it?

A novel, non-invasive system for 100 % subjective predictability of achievable vision after implantation of an IOL.

Who is it for?

Allows presbyopic people with a clear lens, who desire spectacle independence, a preoperative look through genuine intraocular lenses.

How does it work?

Allows people to subjectively experience, compare and digitally assisted measure, prior to the lens exchange, which intraocular lens provides the best vision for them

Smart, functional design. Realistic visual impression looking at objects/pictures in the room.. Intuitive operation.

The new patient journey for refractive lens exchange

Patient selection
Visual acuity quick test
Patient selection

1stQ visual acuity quick test:

Digital RLE suitability test. For the safe selection of suitable RLE candidates. Determines at the very beginning of the patient journey whether a patient is suitable for refractive lens exchange.

Patient information
Virtual Vision Experience
Patient information

1stQ virtual vision experience:

Digital patient information including AR vision simulation with monofocal, EDOF, and multifocal artificial lens.

Educates the patient of what the problem is, why they have it, and what they can do about it.

Vision test through real IOL
Overall visual impression
Vision test through real IOL

RALV® trial vision test:

Preoperative trial vision test through the actual IOL. Gives the patient reassurance about what the vision will be through their preferred IOL. The subjective overall visual impression with the real IOL can be experienced and compared, and enables a self-determined IOL selection.

Preoperative measurements
Visual acuity, contrast, halo/glare test
Preoperative measurements

RALV® preoperative measurements:

Quantitative measurement of visual acuity, contrast and halo/glare using the real artificial lens. What is my vision with the preferred artificial lens?

IOL implantation
Liberty² – the dual lens system
IOL implantation

Liberty² dual lens system (optional):

Securing the predicted surgical outcome from the IOL side. The reversible and at any time optically adjustable trifocal Liberty² dual lens system.

Postoperative measurements
Visual acuity, contrast, halo/glare test
Postoperative measurements

RALV® postoperative measurement:

Quantitative measurement of visual acuity, contrast and halo/glare with the implanted artificial lens. Do the preoperatively predicted and the postoperatively achieved vision match?

1stQ’s IOL Experience with RALV provides a revolutionary new level of reliability in predicting the outcome of surgery.

Leading begins together

Shape the future of lens surgery with 1stQ and RALV.

  • Reliable results
  • Safe patient selection
  • Increased patient satisfaction
  • Reproducible results owing to standardized processes
  • Resource-efficient
  • Optional: Liberty² guarantees results through reversibility

Leading product – strong partnership

RALV is a product of DEZIMAL GmbH. DEZIMAL is a spin-off of ACMIT GmbH (Austrian Center for Medical Innovation and Technology) with a focus on medical engineering and biomedical product development for ophthalmology. DEZIMAL is manufacturer and distributor of RALV®. All rights reserved by DEZIMAL GmbH.

1stQ and ACMIT have been working on joint projects since 2012, pursuing a vision of 100 % predictability in refractive lens exchange. As an IOL specialist with over 30 years of experience in lens surgery, 1stQ has been involved from the outset in the development of RALV® as a consultant. The RALV market launch expected mid 2024 by DEZIMAL GmbH marks a milestone on the way to completing “Vision 100 %”.
