Double Vision: Twin Sisters’ Life-Changing Journey to Clear Sight
Identical twins Karen and Suzanne, both in their early fifties, have done almost everything together since childhood. At seven years old, they were fitted with their first pair of NHS glasses – identical prescriptions and the same moment of realisation that the world wasn’t quite as clear as it should be.

What Is Laser Lens Replacement?
Laser Lens Replacement, also known as Refractive Lens Exchange, is an advanced procedure that replaces the eye’s natural lens with a high-performance artificial lens (IOL). The treatment corrects both distance and near vision, making it an ideal option for people over 45 who rely on reading or varifocal glasses.
Performed under local anaesthetic, the procedure typically takes around 15 minutes per eye. Most patients notice clearer vision within 24 hours and enjoy long-term, stable results. It uses the same proven technology as modern cataract surgery, but carried out proactively, before a cataract ever forms.
As the years went by, both Karen and Suzanne began to notice the natural changes in their vision that come with age. What started as a mild inconvenience soon became a daily frustration, juggling different pairs of glasses for reading, work, and driving. Eventually, they decided it was time for lasting freedom from glasses. True to form, they took the step together, choosing Laser Lens Replacement at Centre for Sight — and even booking their surgeries on the same day.
Trust, Precision, and a Familiar Face
The twins’ surgeon, Mr David Shahnazaryan, Consultant Ophthalmic Surgeon at Centre for Sight, was already a familiar face to Karen, she also happens to be his medical secretary. Having supported countless patients through their own vision correction journeys, Karen had seen first-hand the life-changing results the procedure could deliver. That experience gave both sisters complete confidence that they were in the safest possible hands.
On the day of surgery, the twins were treated one after the other, each undergoing a highly personalised version of the same procedure. Despite being genetically identical, every eye is unique, and their treatments were tailored accordingly. Both surgeries were smooth, precise, and completed within minutes.

A Twin Transformation
Recovery was quick and, within days, both Karen and Suzanne were enjoying better than 20/20 vision, sharper than they had experienced in decades. For the first time since childhood, neither reached for glasses in the morning. Everyday tasks such as reading, driving, and working at a computer felt effortless.
What struck them most was how natural it felt. They described it not as a dramatic change, but as a return to how their eyesight should have been all along. For Karen, working alongside her surgeon added a sense of pride and gratitude; for Suzanne, the experience was defined by the comfort of going through it with her twin at her side.
A Surgeon’s Perspective
For Mr Shahnazaryan, operating on two identical twins on the same day was a first. The challenge lay not in complexity but in ensuring that each sister received a perfectly customised result. The outcome was a success on every level, excellent vision, fast recovery, and two patients thrilled with the result.
He reflects that cases like this underline the precision and predictability of modern lens replacement, and how transformative the procedure can be for patients seeking freedom from glasses in mid-life.
Could Laser Lens Replacement Work for You?
Today, Karen and Suzanne describe their surgery as one of the best decisions they have ever made. It gave them back the clarity and freedom they’d missed for years, and the shared experience brought them even closer together. Their story is a testament to how far modern eye surgery has come, and how transformative clear vision can be at any stage of life.

Patient Success Stories
A first class experience
The whole process, start to finish, is first class. The facility at East Grinstead is superb and the staff were friendly and professional. The consultant, Saj Khan, is fantastic, a great communicator as well as being a leader in his work.
I had replacement lenses, after 3 months they became a little cloudy, distorting my vision. This is a known problem. I booked a consultation, within 2 hours I had been assessed and had laser treatment. No fuss, no problem, job done.

5* Lens Replacement Procedure
I had tri focal lens replacement, both eyes done on the same day by Mr Daya. I wish I’d had it done sooner, it’s totally life changing. I researched the procedure for many months and selected Centre for Sight and I’m so glad I did. The whole process is first class from the very first contact, the initial tests could not be more thorough and the procedure is totally painless. The whole team could not be more helpful, I cannot praise them enough. I have perfect all round vision now so if you’re considering having the procedure done then this is definitely the place to choose you won’t regret it
