At CHEC, we’re incredibly proud of the talented and dedicated individuals who make up our team. Today, we’re shining a spotlight on our National Clinical Lead, Karen Dewhurst, whose journey within optometry and her rise within CHEC is a truly inspiring story.  

Karen’s path began at Aston University, where she honed her skills in optometry. Her early career saw her immersed in the diverse world of independent practice. “My pre-reg year and my first year as a

newly qualified optometrist were in an independent practice,” Karen recalls. “They did things such as low vision aid assessments, stable glaucoma management schemes, and even domiciliary home eye tests. I think early on I got quite a varied experience.”  

This early exposure to different aspects of eye care proved invaluable. “Independent optometrists’ do as much as they can, and you learn a lot,” Karen reflects. “Obviously, your first home visit sight test, you realise that it isn’t the same as at Uni! You simply have to adapt to the room you’re in and the patient in front of you.” This adaptability and willingness to learn would become hallmarks of Karen’s career.  

In 2008, Karen moved to Boots, where she spent 12 years, initially as a mobile optometrist covering multiple sites before settling into more regular roles. It was in 2019 that a pivotal moment occurred. Living and working in an area where CHEC was expanding its services, Karen received an email indicating that CHEC now offered YAG laser procedures in the area. Aware of the lengthy waiting lists at the local hospital, she reached out to enquire about CHEC’s wait times.  

To her surprise, the response came directly from CHEC’s CEO, Imran Rahman. “He told me the wait times, which were really short in comparison,” Karen explains. Imran’s personal touch and willingness to explain CHEC’s processes led to an invitation to a YAG clinic. “The next thing I knew, I was training to do YAG laser and was going to become a locum doing just one day a week.”  

During one of her training days, the conversation took another exciting turn with Imran mentioning that CHEC were opening a local site in Blackpool. She interviewed and became CHEC’s first employed clinical optometrist.  

Starting just two days before the first lockdown offered its own test and Karen’s role quickly evolved. “We had to spread patients throughout the week, and we welcomed theatre patients on weekends, 7 am to 7 pm,” she says. Not being furloughed provided unique opportunities. “I would help out with theatre and diagnostic clinics, which most optometrists don’t get the chance to do.”  

Karen credits Imran’s mentorship as a significant factor in her growth. “To be trained by Imran was an amazing opportunity, and he was so gracious with his time. When I had questions, it was Imran; there was no clinical support team at that point.”  

Her leadership potential soon became evident. “I was then asked to sit in on interviews for optometrists, and before I knew it, I was the one holding the interviews. Then I started training optometrists when they first joined. This is when I became a regional clinical lead.” As CHEC continued to expand, Karen’s responsibilities grew, culminating in her current role as National Clinical Lead, where she now manages the northern and southern clinical leads.  

In her current position, Karen’s focus is broad and impactful. “I am doing the training that falls into clinical governance, and I am writing policies for treatments,” she explains. She also remains actively involved in professional development, as evidenced by her recent peer review at CHEC’s first CPD conference. Discover more about our CPD Conference here.  

Despite her impressive trajectory, Karen remains grounded. “I find it amazing because I don’t see myself as ambitious or driven; I’d be happy still being a local optometrist, although I did find the ‘sales’ aspect a difficulty, I was never a very good salesperson.”  

It was the sales aspect of her role that made her consider a career change, but instead CHEC presented a new path. “I was considering leaving the profession and becoming a teacher when CHEC fell into my lap really; I was really lucky. I had a great relationship with my NHS Partnership Executive, and I simply reached out to her.” Karen also notes the evolving landscape of optometry. “I never even really considered hospital optometry or academia. None of it had kind of been talked about. Whereas I think nowadays, there are different avenues for optometrists, and they’re more widely discussed.”  

A defining aspect of CHEC’s ethos, as Karen highlights, is their approach to professional development. She recalls a powerful quote from Imran: “We will never push you out of your competency as an optometrist but will absolutely push you out of your comfort zone.” This philosophy resonates deeply with Karen. “CHEC invests in people, and rather than simply looking at a CV, which all optometrists will have the same qualification, we look at how that person will fit in with the culture and core values of people because we train everyone the same.”  

Looking to the future of CHEC, Karen is enthusiastic about several key areas. “I’m excited for the expansion of the services we offer; we’ve obviously launched MIGS and VR services.” Maintaining a connection to patient care remains a priority for her. “I’m excited to continue doing clinics because it’s important to me to retain that link with higher management and the people and processes on the ground and ensuring that the right decisions are being made.”  

Karen is also passionate about the learning opportunities CHEC provides. “We’re getting more Independent Prescribing qualified optometrists, and I would like to see more optometrists doing more clinics than just cataract and YAG consultations. I would also like to implement ophthalmologist mentors. I obviously had Imran, and I think everyone should have an opportunity like that.”  

Ultimately, Karen believes CHEC offers a unique environment for both patients and professionals. “CHEC not only offers patients care in their community, but we also offer our optometrists and doctors a community where they talk to each other, asking why a particular medication has been prescribed and why a test has been booked. To have a direct line to this information is really valuable to have.”  

When it comes to Continuing Professional Development (CPD), Karen emphasises CHEC’s patient-centric approach. “I think what makes us stand out is that we listen. We ask optometrists what points they need, what they’d like to learn. It’s also impressive that people like Mahmoud Rabie, our Clinical Director of Ophthalmology, deliver some of our CPD events. To have a doctor who specialises in that topic is amazing. And we do tend to get an expert on the subject matter to present.”  

Karen Dewhurst’s journey is a testament to the opportunities and growth that CHEC fosters. From a local optometrist who was considering leaving the field to a national clinical lead shaping the future of community eye care, her story is an inspiration to us all.  

CHEC are celebrating the completion of its first cataract surgery training initiative for NHS registrars. 

Dedicated to providing future generations of ophthalmologists with high-quality and experiential training, CHEC welcomed a cohort of ST1 to ST7 registrars to its Preston, Blackpool, Coventry, Gateshead and Warrington hospitals, so they could gain real-time exposure to cataract surgery, a high-volume and essential procedure in ophthalmology. 

The training, which ran for 12 months up to February 2025, was delivered under the guidance of experienced consultants from CHEC. Trainees gained proficiency in phacoemulsification surgery – the gold-standard technique for cataract removal – using state-of-the-art phaco machines; advanced biometry technology; intraocular lens selection to ensure precision in vision correction, and premium intraocular lens implantation. They also received anterior segment management training to enhance their ability to address complex cases, and trained in the use of modern ophthalmic microscopes and instrumentation – critical for high-precision surgical techniques.

Developed by Mahmoud Rabie, Clinical Director for Ophthalmology at CHEC, the training was delivered in partnership with NHS deaneries. A new cohort of NHS registrars are now undertaking CHEC’s second year of cataract surgery training provision, which began recently. 

The cataract surgery training comes alongside a series of additional initiatives, including a new CPD cycle which commenced in January. Last year, CHEC also launched an independent prescribing course placement, helping optometrists to develop their diagnostic skills and understanding of the links between the theory and practice of prescribing, ensuring they can manage patients therapeutically and issue necessary prescriptions.

Mahmoud said: “We have made a commitment to ensuring trainee ophthalmologists across the country have access to the opportunities and experiences they need to develop hands-on, professional skills. The completion of the first year of our cataract surgery training, and the upcoming launch of its second year, means we’re playing a key role in the development of future ophthalmic surgeons, and we’re pleased that we’ll be integral to their success.

“We take it upon ourselves to be at the centre of developing ophthalmology talent in the UK and are in a fantastic position to offer these trainees the chance to work alongside our brilliant team to hone their skills in our specialist hospital environments. We look forward to seeing how this new cohort progresses, and to working with many more trainees in the future.”

Berk Abay, an NHS registrar who recently completed the cataract surgery training with CHEC, said: “During my seven months as a trainee surgeon at CHEC Blackpool, I had the privilege of working under the guidance of expert ophthalmologists, whose encouraging and relaxed approach greatly boosted my confidence. Under their mentorship, I was able to significantly enhance my cataract surgery skills. CHEC’s theatre staff were incredibly supportive, always willing to assist, and their dedication to compassionate, patient-centred care was truly inspiring. 

“The culture at CHEC fosters an excellent learning environment, making it an invaluable place for trainee surgeons to develop their skills and grow in confidence.”

What a fantastic weekend it was at 100% Optical! The CHEC team was absolutely thrilled to connect with so many familiar faces and welcome a host of new ones to our stand. It was a whirlwind of engaging conversations, shared smiles, and a real buzz of excitement. 

Our stand was a hive of activity, and we were delighted to see so many people drawn in by our interactive experiences. We aimed to create a fun and informative atmosphere, and it’s safe to say we achieved just that! The cataract surgery activity proved incredibly popular, giving delegates the opportunity to complete a capsulorhexis, the surgical technique used to create a window in the anterior capsule wall of the lens of the eye to aid cataract removal. Hosted by clinicians from CHEC’s UK-wide surgical team, Dr Moemen Elnawawy and Juan Alberto Lopez Ulloa. Our chocolate selfie machine was a delightful hit, capturing countless smiling faces and creating sweet memories. And of course, who could resist a warm cup of free coffee on a busy exhibition day? 

A highlight of our weekend was undoubtedly welcoming students from across the country and provide them with their very first experience of eye surgery, guided by our expert ophthalmologist, Moemen.

Witnessing their enthusiasm and curiosity was truly inspiring, and we hope this experience ignited a passion for ophthalmology in these future healthcare professionals. Olivia, a student of Optometry at the University of Hertfordshire said: “I’ve never tried anything like this before, and to be able to practice here with a CHEC Surgeon is really amazing!” 

Jose Bailey, Chief Commercial Officer, said: “Over the last 12 months, we continued to invest in the expansion of our hospital sites and further built on our ongoing success in training and professional development. 100% Optical was the perfect industry platform to share our latest updates as well as host practical experiences, and for delegates to get hands-on themselves. It was excellent to see optometry students share their ambitions and try their hand at cataract surgery with our Cataract Dry Lab. It was also the ideal opportunity for us to engage with industry peers about what we were collectively doing to improve eye care for our patients, which had, and always will have been, our number one priority.” 

The energy at our stand was infectious, with laughter and lively discussions filling the air. We were overwhelmed by the positive feedback we received, and it was a pleasure to connect with so many passionate individuals who share our dedication to eye care.

Thank you to everyone who took the time to visit our stand. Your enthusiasm and engagement made our weekend at 100% Optical an unforgettable experience. We look forward to seeing you all again soon!

As one of the leading NHS providers of community ophthalmology, CHEC is committed to collaborating with our partners to deliver exceptional care. With thousands of specialists working with and referring to CHEC, we’re at the forefront of healthcare innovation. We understand the significant impact cataracts can have on vision and daily life, and we’re here to address your questions and dispel any myths you may have heard.

Myths About Cataracts

Cataracts are one of the most common reasons for vision loss in adults. One of the more misunderstood eye conditions here’s a quick myth buster to help you sift fact from fiction:

Myth 1: Cataracts are growths on the eye

Possibly one of the most common misconception. A cataract is not a growth on the eyeball, but the clouding of the eye lens. It happens when the transparent proteins in the lens lose their elasticity and begin to clump together. Over time, the clump builds up – and this causes vision problems.

Myth 2: Cataracts only affect the elderly

Although age is certainly the biggest contributor to cataracts, and by the age of 80, around half of us will have developed them. Cataracts can also affect younger people and even babies can develop them. Cataracts can also be caused by lifestyles and health conditions, eye injuries and genetic disorders, not to mention smoking and diabetes, can all increase the risk of developing them.

Myth 3: Cataracts spread from one eye to the other

Cataracts don’t spread from one eye to the other. While they often develop in both eyes around the same time, this isn’t always the case. Cataracts develop independently in each eye, and there’s no way for them to transmit between eyes.

Myth 4: The only symptom of cataract is blurry vision

Blurred vision is just one of several ways cataracts can affect eyesight. They can also distort how light passes through the lens, leading to halos around lights, changes in colour perception, double vision, and increased glare, particularly at night. This heightened glare often makes night driving difficult for those with cataracts.

Myth 5: Cataracts need to be ‘ripe’ before you can operate

Thanks to significant advancements in technology, cataract surgery has come a long way. Previously, cataracts had to be quite advanced (“ripe”) before they could be surgically removed. Today, we can operate at a much earlier stage, often before you even notice significant vision changes. This offers greater choice in treatment options and frequently leads to better outcomes.

Myth 6: Cataract removal is difficult and time consuming

Cataract surgery is recognised as one of the safest and most frequently performed procedures globally. Our experienced surgeons routinely complete up to 20 cataract removals in a single day. Typically performed under local or topical anaesthetic, the surgery itself usually takes just 10-15 minutes, allowing patients to return home within a few hours.

Myth 7: Cataract surgery is painful

Cataract surgery is typically a comfortable procedure. Upon arrival, you’ll receive fast-acting eye drops to numb your eye, ensuring a pain-free experience. You might experience some mild aching or a gritty sensation for a few days afterward, but this usually subsides quickly and can be easily managed with over-the-counter pain relief like paracetamol.

Myth 8: Cataract surgery takes ages to recover from

Recovery after surgery is typically quick, with most people able to resume their normal daily activities within 24 hours. While some initial blurriness is normal, your vision should improve rapidly. We do recommend avoiding strenuous activities for about a week to allow for optimal healing.

Myth 9: I’ll still be short-sighted afterwards

Cataract surgery offers the significant benefit of correcting refractive errors such as near-sightedness, farsightedness, and astigmatism. By replacing the clouded lens with a precisely chosen intraocular lens (IOL), patients often experience a dramatic improvement in vision and may even become less reliant on glasses or contact lenses.

Myth 10: Cataract surgery removes floaters

Cataract surgery is removal of the lens and inserting a new one. Floaters are imperfections floating around in the vitreous gel that fills almost the entire eyeball, and it’s actually behind the human lens. If you have floaters before surgery, it may become more noticeable.  In any case, any change in your existing floaters, or any new ones, you should seek advice from your eye care professional.

At CHEC, we’re committed to providing the highest quality eye care. We’re pleased to introduce our new vitreoretinal surgery service, now available at several of our hospitals.

The specialised field of ophthalmology focuses on treating a range of diseases and conditions affecting the retina and vitreous of the eye, including epiretinal membranes (ERM) and macular holes, both of which dramatically reduce a person’s ability to live independently. 

CHEC has launched the vitreoretinal surgery service from its Trafford and Stockport hospitals and plans to expand it across more sites in coming months, to improve access and convenience for patients undergoing the life-changing surgery. CHEC’s state of the art hospitals are equipped with the latest ophthalmology technology including advanced imaging systems and the latest surgical tools, with a dedicated team of specialist consultants and highly trained support staff ensuring the highest standards of vitreoretinal care, before, during and after the procedure.

In 2023/24, CHEC treated more than 372,000 ophthalmology patients with an average wait time of less than four weeks.
