Research and development

Optegra is working towards becoming a centre of excellence for ophthalmic clinical research and we are currently working with suppliers, surgeons and academics in a variety of research areas. Optegra Eye Sciences is committed to championing innovations in eye care.

Championing innovations

The Eye Sciences team works with surgeons, industry partners and academics to identify and evaluate new treatments and technologies. This involves preparing new treatment proposals, conducting reviews of the literature and consulting with external ‘experts’ where appropriate. This has worked successfully to evaluate new glaucoma therapies, new implantable telescope treatments, new laser technology for performing cataract surgery, corneal inlays for treating presbyopia and new anti- VEGF treatments for AMD. Once new technologies are approved by Optegra’s Medical Director, Medical Advisory Committees and Optegra’s Managing Director, Optegra Eye Sciences works with surgeons and suppliers to develop the Optegra patient pathway and with Optegra’s marketing department in developing materials and communications for patients and professional partners.

EYLEA®

A new treatment for wet AMD has been licensed for use in the UK. EYLEA® (aflibercept) injections work in a similar way to treatment with Lucentis. Studies suggest that intravitreal aflibercept given every 2 months (after 3 initial monthly doses, and for at least the first year) has similar efficacy / safety to monthly Lucentis injections for patients with wet AMD. It reduces the requirement for monthly follow-up visits (there is no requirement for monthly monitoring) and it is FDA-approved. It has been approved by NICE.

IMT

The IMT or ‘implantable miniature telescope’ is now available at Optegra.  This is the only FDA-approved ophthalmic telescope implant as a management option for end-stage age-related macular degeneration (AMD).  This treatment has been shown in clinical trials to improve quality of life for those with central vision loss in both eyes.

Surgeons Mr Andrew Luff and Mr Brendan Moriarty will initially offer this new treatment at Optegra Surrey Eye Hospital, Optegra Solent Eye Hospital and Optegra Manchester Eye Hospital.

LENSAR™

Optegra is the first national eye care provider to offer this state-of-the-art laser technology to patients across all of its UK hospitals. From July 2014 LENSAR is offered for all Clarivu™ and cataract procedures to give the optimum results for the patient.

The femtosecond laser technology (which is CE Marked) is very user-friendly and comfortable for the patient. The servo-controlled docking system has a “no corneal touch” liquid patient interface for greater patient comfort which avoids any compression or distortion to the cornea.

The treatment algorithms have been optimised for each cataract grade and this purpose designed integrated system is highly efficient and can eliminate or significantly reduce the amount of ultrasound energy required to complete the cataract removal. LENSAR can be used in both sterile and non-sterile environments and with its retracting laser head, allows unrestricted access to the treated eye after the laser procedure.

Optometrists and referring GPs interested in offering their patients this latest technology are welcome to contact their local Business Development Manager.

Research and development collaborations

Optegra and Aston University Research Meeting

A productive and novel research workshop session was held recently at Aston University to facilitate research collaborations between Optegra and academia.

The aim of the day was to showcase Aston University’s research capabilities and to identify opportunities for collaborations between researchers at Aston University, Optegra and Telehealth Solutions (THSL). The day was very well attended with over 30 academics, postgraduate students and post-docs as well as representatives from Optegra and THSL taking part.

Professor Helen Griffiths (Executive Dean, School of Life & Health Sciences) opened the day which started with presentations from Optegra’s Managing Director, Gareth Steer, Optegra’s Head of Eye Sciences Dr Clare O’Donnell, and Donal Markey, Clinical Director from THSL.

Professor James Wolffsohn then kicked off a ‘rapid fire’ session of short presentations with the general theme of eyes, brains and e-healthcare research.  Professor Wolffsohn talked about a VisionCare Research/Aston University/Optegra partnership being able to offer a complete clinical trial solution for ophthalmology research, including intraocular lens technology.  Dr Nichola Logan then gave an overview of her group’s novel research into myopia development in children encompassing MRI technology.  Dr Leon Davis gave an update on his innovative work into presbyopia.  Professor Brian Tighe’s presentation was an informative and entertaining summary of his group’s work on corneal biomarkers.  Measurement of certain proteins in the tear film can be used to monitor corneal wound healing after ocular surgery.  Dr Frank Eperjesi discussed his varied research interests encompassing nutrition, macular pigment, tear film and ocular aberrations.  Dr Doina Gherghel gave a fascinating overview of using ocular metrics to understand cardiovascular disease.

Dr Kate Sugden from Aston’s Institute of Photonic Technologies presented her work relating to understanding issues relating to OCT technology, which is increasingly being used in ophthalmology.

In E-healthcare Dr Xiaohong Peng discussed wireless sensor networks for smart monitoring.  The session then moved onto Neuroscience and Professor Paul Furlong described research activities at the Aston Brain Centre, a world leading centre of excellence for the study of brain development and imaging.  Professor Furlong discussed several projects including Alzheimer’s disease and how the disease could now be detected at an earlier stage. Professor Stefano Seri presented FMRI research to map changes in neural processing with age. Dr Stephen Hall discussed research of new approaches to look at drug actions using biomarkers. Professor Helen Griffiths then rounded off the session with a presentation on aspects of her research relating to statins, cholesterol and the blood/brain barrier.

The session was followed by a poster session and networking lunch where researchers and representatives from Optegra and THSL were able to discuss opportunities for future collaborations and next steps.
