Rayner IOLs

Prof Graham Barrett presents on positive spherical aberration at Rayner's 2023 ESCRS symposium.

Prof Barrett

Additional perspectives:

Prof Ribeiro

Professor Filomena Ribeiro presents on finding the optimal balance of aberration in lenses to extend the depth of field

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 Rocha

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

Dr Hu

Dr Jerry Hu explains the beneficial outcomes for patients with positive spherical aberration IOLs

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

Additional perspectives:

Dr Hu

Dr Jerry Hu explains why enhanced monofocal IOLs are a good choice for post-LASIK patients

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

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

Prof Auffarth

Additional perspectives:

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

Additional perspectives:

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

Additional perspectives:

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 Oliver Findl discusses the rotational stability of the RayOne EMV platform and factors to take into account when dealing with highly myopic patients

Prof Findl

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

Prof Auffarth and Dr LaHood

Additional perspectives:

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

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

Additional perspectives:

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)

Dr Mark Torres discusses the empowering data he has collected using the RayPRO platform for his medical practice

Dr Torres

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

Dr Zaldivar
