I grew up in South Devon where I developed a deep love of the countryside and a strong interest in ecology and environmental responsibility.

I later completed my ophthalmology training in South Wales and spent 12 years there before deciding to return to Devon where I now live with my wife Kate, who is an artist and sailing instructor. I am a very keen water sports enthusiast and enjoy kitesurfing, paddleboarding and swimming whenever possible.

These days I am fortunate enough to be able to split my working hours between Devon and Wales and I feel proud to offer cataract surgery to patients living in these beautiful rural locations.

About image


I have a keen interest in developing devices that deliver improved patient experiences and which make my job, and that of other ophthalmologists, easier. I am proud to have innovated these successful British surgical and medical devices.


I developed the SP.eye intravitreal injection device with other ophthalmologists. It is a highly efficient method that is safe and secure and more comfortable than traditional injection techniques. It is also the first of its kind in the world.

Your ophthalmologist may have recommended injecting a specific type of drug (anti-VEGF) into the back of your eye to prevent new blood vessels growing in the retina. Without treatment these blood vessels can leak fluid and blood, thereby reducing your vision.

The SP.eye precisely guides the very fine needle and may be used without the metal spring usually employed to keep your eyelids open.


enVoi™ is a free app enabling you to refer yourself for surgery and receive a consultation from the comfort and convenience of your own home. This means only one visit to the hospital for the surgery itself.

I developed the enVoi™ specifically for ophthalmology. It has improved both patient experience of cataract surgery and that of colleagues working in community optometry.


I am an experienced NHS consultant ophthalmologist, holding appointments at:

  • Royal Devon and Exeter Foundation Trust, Barrack Road, Exeter, EX2 5DW
  • I was previously a consultant at: Hywel Dda University Health Board, Ystwyth Building, St Davids Park, Jobswell Road, Carmarthen, SA31 3BB

I am also a highly trained and experienced oculoplastic and glaucoma surgeon, having undertaken fellowship training in the UK.

Patient Testimonials

I am a very experienced cataract surgeon achieving excellent patient satisfaction

Sam is a first class professional in his field - totally honest and trustworthy.
Friendly, thorough, professional while being very clear in explaining his findings and in giving advice. I have been delighted with the outcome of my visit, and would have no hesitation in recommending Mr Evans to other prospective patients.
Excellent advice, attention, information, given with kindness and consideration.
Consultation very clear and helpful. Mr Evans was most approachable, friendly and informative. I felt he listened to my concerns and worries and took time and care to help me make decisions about the next step.
Everything went ok and my sight is now as good as it has ever been.
Even though the lenses I had before were good, these were a step up on that... quite remarkable.
Thank you so much for your care and kindness. You were brilliant. It was an amazing procedure and it means so much to me to have my sight back at last.
Just a quick note to say a huge thank you for everything you did. Your manner is second to none and I can’t thank you enough for putting me at ease during the procedure. My vision now is so much better—my son says I can see too much now!
I am extremely grateful to you for your kindness last Friday when you operated on my cataract. My nervousness proved to be so unnecessary as it was painless and very swift. My grateful thanks for all you did.
To Mr. Sam Evans, brilliant eye surgeon. I just wanted to say a HUGE THANK YOU to you and your wonderful team for my life-changing eye operations. For many years I have struggled with poor vision and thanks to you my quality of life will be transformed.
