Prof Barrett

Mr Barua

Mr Ankur Barua explores the optics of the eye and the role of spherical aberration in shaping the future of refractive surgery.

Dr Karolinne Rocha delves into the evolution of spherical intraocular lenses, aspheric lenses, and the progress made toward achieving the optimal level of spherical aberration.

Mr Turnbull

Mr Andrew Turnbull elaborates on the refraction of light rays passing through the periphery versus the centre of the lens using positive spherical aberration with RayOne EMV.

Prof Barrett

Professor Graham Barrett outlines his decision to incorporate positive spherical aberration in the development of RayOne EMV.

Professor Graham Barrett discusses the use of RayOne EMV for patients with LASIK and large ablation zones, alongside the patient selection criteria for individuals with irregular corneas.

Prof Barrett

Prof Auffarth, Mr Barsam and Dr Dmitriew

Professor Gerd Auffarth, Mr Allon Barsam and Dr Andrzej Dmitriew share their views on adding spherical aberration with RayOne EMV to post-myopic LASIK patients.

Peer2Peer | Prof Barrett Answers RayOne EMV FAQs

Professor Barrett provides additional insights into the use of RayOne EMV for patients who have undergone LASIK surgery.

Professor Gerd Auffarth presents on varied patient outcomes achieved through the utilisation of different offsets using RayOne EMV.

Prof Auffarth

Dr Rocha

Dr Karolinne Rocha discusses targeting different offsets and how to achieve ‘modified monovision’.

Dr Kuan

Dr Yeo Tun Kuan presents on the findings of his clinical study on RayOne EMV, where patients were grouped into bilateral emmetropia and monovision categories.

Mr Stuart

Mr Alastair Stuart describes how he utilises RayOne EMV to implement modified monovision, typically incorporating an offset of -1.50 D in the reading eye, also discussing how he communicates this approach to his patients.

Dr Endl

Dr Michael Endl explains what offset he’d recommend to surgeons who are using RayOne EMV for the first time.

Dr Cyres Mehta explains how to choose patients for different types of IOLs and shares techniques for counselling patients to manage their expectations.

Dr Cyres Mehta

Prof Barrett

Professor Graham Barrett highlights the minimal limitations associated with RayOne EMV compared to trifocal IOLs.

Mr Barsam

Mr Allon Barsam discusses why RayOne EMV has become his ‘go-to default lens’.

Dr Dmitriew

Dr Andrzej Dmitriew is now providing more patients with extended depth of focus lenses as an enhanced approach for monovision and a viable alternative to multifocal IOLs.

Mr Barua

Mr Ankur Barua explains why RayOne EMV is an excellent choice for patients seeking enhanced range of vision beyond what a standard monofocal IOL can offer.

Dr Botta

Dr Josefina Botta suggests RayOne EMV over multifocal IOLs for patients in search of an extended focal range without encountering trifocal IOL drawbacks.

Dr Nankani

Dr Gul Nankani explains why he recommends RayOne EMV to patients seeking spectacle freedom, especially to individuals who have compromised eye health such as retinopathy.

Dr Hürmeriç

Dr Volkan Hürmeriç discusses how RayOne EMV offers a satisfactory level of intermediate vision, making it a favourable alternative to multifocal IOLs.

Professor Graham Barrett answers the question “Is there anyone we should not put this lens in?".

Prof Barrett

Allon Barsam shares RayOne EMV vs Acrysof Vivity clinical results from a large patient cohort.

Mr Barsam

Dr Gatinel

Dr Damien Gatinel objectively reviews the RayOne EMV and Acrysof Vivity optical designs.

Professor Findl

Professor Oliver Findl shares findings from a clinical study comparing RayOne EMV and Vivity.

Because the Centers for Medicare and Medicaid Services consider the RayOne EMV a non-premium lens, it means that US surgeons cannot bill patients directly for this IOL. Dr Eric Donnenfeld and Dr Jerry Hu discuss the billing packages that they have created to enable them to offer it to their patients without actually charging for it.

Dr Donnenfeld and Dr Hu

Professor Gerd Auffarth and Dr Ben LaHood offer their general perspective on the debate between hydrophobic and hydrophilic materials.

Prof Auffarth and Dr LaHood

Dr Yeo and Prof Barrett

Dr Tun Kun Yeo and Professor Graham Barrett answer questions regarding the correlation between hydrophilic lenses and posterior capsule opacification (PCO) at the APACRS 2023.

Dr Ben LaHood discusses the known risk factors and adaptive techniques for hydrophilic IOLs.

Dr LaHood

Professor Ramin Khoramnia delved into the advantages of supplementary lenses, with a special focus on the DUET method which is a reversible trifocal option for patients.

Prof Khoramnia

Dr Desai discusses his study on glaucoma patients using RayOne EMV and Vivity - including patient satisfaction and spectacle independence.

Dr Desai & Dr Stonecipher

Professor Barrett elaborates on the initial concept behind RayOne EMV and its classification.

Peer2Peer | Prof Barrett Answers RayOne EMV FAQs

Professor Barrett discusses the advantages of RayOne EMV, particularly its positive spherical aberration which offers less sensitivity to decentration compared to negative spherical aberration IOLs.

Peer2Peer | Prof Barrett Answers RayOne EMV FAQs

Professor Barrett delves into the distribution of positive spherical aberration in RayOne EMV, taking into account pupil size.

AEON (eye drops)

Ms Purvi Thomson discusses how a condition often dismissed as mere 'dry eye' can actually pose significant problems for patients.

Ms Thomson

Dr Schmickler

Dr Stefanie Schmickler explains her rationale for administering eye drops prior to biometric measurements and shares her strategies for motivating patients to maintain their use of eye drops after surgery.

RayPRO (patient reported outcomes platform)

Mr Allon Barsam shares his positive experience with RayPRO since integrating it into his clinic 8 months ago. He highlights the value of the PROMs tool, compatible with all IOLs, and emphasises the importance of collecting statistical results to understand patient satisfaction with different lenses.

Mr Barsam

Dr Roger Zaldivar discusses using RayPRO to compare different IOLs based on patient-reported outcomes. This includes factors like dysphotopsia, spectacle independence, and overall satisfaction.
