Guided by Erik Smidt

Opening Session, Friday, 29th April 2022

Welcoming Address of the president  – Armin Duddek

Keynote 1; Multifocal Scleral Lenses – Dr. Diego López Alcon – Scleral lenses are, without a doubt, the contact lenses that have grown the most in recent years. As their name suggests, they are lenses that rest solely and exclusively on the sclera. Therefore, every effort must be made to ensure that the lens does not touch the cornea or the limbus. Scleral lenses have become for many specialists the first choice of optical treatment for irregular corneas and ocular surface diseases. They are also able to compensate for myopia, hyperopia, astigmatism and presbyopia in healthy corneas. The combination of scleral lenses and multifocality is a challenge for manufacturers and scleral lens specialists. In this presentation we will discuss the limitations of contact lenses in general. We will also discuss the differences in fitting multifocal hydrophilic lenses and multifocal scleral lenses. And finally, we will discuss what areas of knowledge and research need to be addressed in order to understand the real effect of multifocal scleral lenses on vision.

Keynote 2; Smart Contact Lenses – the Past, the Present and the Future – Prof. Dr. Andrés Vasquez Quintero, University of Gent, Belgium – with a short introduction of Peter Vermeulen –
Recent advances in wearable electronics are not only focusing on devices integrated on textiles and accessories, but also on conformal devices in close contact with the human body. The potential applications include smart contact lenses. These lenses are foreseen to be applied in different fields ranging from biomedical diagnosis and entertainment to vision correction, among others. However, challenges lie ahead mostly regarding to their integration into fully autonomous systems. This talk will explore different applications for smart lenses, visiting current technology and challenges for the future.

Keynote 3; Accommodating IOLs and the Holy Grail – Dr. David Spalton –
Cataract surgery now centres on providing spectacle independence for distance, intermediate and near vision. All multifocal designs compromise light distribution causing loss of contrast and dysphotopsia from glare and halos. These problems would be solved by an accommodating lens. There have been numerous designs all of which have so far failed. Interest now has moved to IOL designs which change their radius of curvature under accommodative stimulation. This presentation reviews the present state of development of IOLs which eventually transform cataract surgery.

CL Lectures, Friday, 29th April 2022

New Technology in Blocking System – Dr Marco Iovino, Medlac srl. Italy – Contact lenses produced by Lathe cut had a big improvement in cutting precision with new technology developed by lathes manufacturers. Blocking system remains a critical element to the manufacturing process and it involve into the final quality of the lenses more than we can know. The potential of the new MED-BLOCK system was developed and studied with a scientific approach to evaluate the actual benefits by comparing it to the cost of the technology itself.

Evolving Ortho-K Lens Construction to Optimize Myopia Control – Randy Kojima, Pacific University Oregon –
Orthokeratology lenses are being employed as the principle optical intervention for myopia control in children. However, how has lens construction evolved to meet this application? This course will review new approaches and the corresponding science and research to create improved outcomes for children.

Commercial presentations 7 – 9: Larsen Equipment Design, Schneider GmbH, DAC International

Software Validation in the CL Industry  – Filippo Selden, Advanced Medical srl, Italy – The International Framework is consolidating the path towards globalization of Medical Devices’ regulatory requirements, see “International Medical Device Regulators Forum (IMDRF)”. The new environment is pushing all actors in the CL Industry into focusing on new areas of betterment. The Covid emergency has contributed to accelerate this phenomenon.
This talk will describe the concept of Software Validation, the Regulatory Context, its role in a Lab’s own Quality Management System and how Advance Medical has approached the subject with its own Software Validation Protocol. Since the Medical Device Manufacturer is the “responsible for validation”, the Protocol has been structured to assist the Manufacturer’s QMS management as referenced in the quality standards of ISO 13485:2016 and GMPs specific for the production of medical devices, based on a risk analysis (ISO 14971:2016) that takes into account the Software’s impact on Quality Management System processes.
The Protocol has already been implemented in TS Lac, a leading company in the Italian market. The overall project was coordinated by Effetre, a regulatory and quality consultancy company with 30 years of experience in the field of contactology.

IOL Session, Friday, 29th April 2022

Multifocal intraocular lenses after more than 10 years. Proper use. – Dr. Gonzalo José Bernabeu Arias, Madrid Hospitals, Madrid, Spain – In recent years, the use of multifocal intraocular lenses has become a common tool in cataract surgery. However, in my presentation, I will try to convey to the audience the importance of the proper use of these lenses, when to use them, who not to use them, why there are cases of dissatisfied patients, and how to make a good selection of the ideal patient for this implant. 
My experience with these lenses could not be better, but it requires a constant study of the different types of lenses, how each of them works, having good technology in the ophthalmology office and being a good surgeon.

Update and New Challenges in Toric Intraocular Lenses – Dr. Ana Hervás Ontiveros, Hospital La Fe Valencia, Valencia, Spain – New and updated toric lenses, calculators and regression formulas offer the opportunity for more accurate lens selection for our patients.
Concurrently, improvements in topographic evaluation of corneal keratometry have allowed for a decrease in unplanned residual corneal astigmatism. Measuring posterior corneal astigmatism is especially valuable in eyes with corneal pathologies when planning to implant toric intraocular lens and now allows access to this patient population.

Commercial presentations 14 – 16:

Optical Effects of IOL Complications – Dr Timur Yildirim  – Nowadays, there is a wide range of different intraocular lens models on the market, especially in terms of variations of optic designs. In addition to normal monofocal lenses or so-called monofocal+ lenses, there are EDOF lenses with enhanced depth of focus and diffractive trifocal lenses. In general, there is a trend towards developing optics that have as few side effects as possible. By side effects we mean above all optical phenomena such as halo, glare and scattered light. It has to be said that trifocal lenses generally have these kinds of complications. The advantage, however, is that the trifocal lenses produce relatively assured good vision in one area, especially at close range. New lenses on the market, such as special EDOF lenses, show a low side effect profile. However, these lenses do not have a 100% guarantee of covering the entire visual range and it is very often necessary for these patients to wear reading glasses.
The lecture will go into detail about the individual lens models and the effects on optical side effects and provide relevant examples.

MDR Lectures/ Workshops, Saturday, 30th April 2022

EUROMCONTACT – the Voice of the CL and CLP to the EU: main Challenges and Priorities for the Industry in a Challenging Political Environment – Pascale Rouhier

Contact Lens Materials – Update on PFAS Questions – Pascale Rouhier – The aim of this session is to ensure that the wider industry is aware of the significant, and potentially existential challenge that our industry is facing in light of the potential ban, or heavily restrictive regulation, of substances that are considered as PFAS: used in fluoro-silicone acrylate RGP materials, some hydrogel materials and some components used in lens care products.
This session will briefly cover the timeline of this challenge from the initial question raised by the five EU Member States (that are moving to have PFAS regulated under the REACH regulations), through to the public consultation that will be held by ECHA (European Chemicals Agency), and to what efforts the PFAS working group of EUROMCONTACT have thus far taken. This will cover the ongoing work on developing industry white papers to support the concept of essentiality of use, both in terms of the clinical application of lenses that depend upon high oxygen permeability RGP materials, as well as the technical requirements of why PFAS substances are included in the various polymers.

Commercial Presentations 17 – 18: Boston Materials, Contamac Ltd.
