The First High Myopic (Short Sighted) Visian ICL Inserted In The UK

Patient SR, a 27 year old accountant attended AVC enquiring about vision correction approximately 5 years ago. She had enquired about refractive surgery in the past but had been informed she was not suitable for any procedures. She was recommended to AVC by her medic friend who had had treatment with us.

Upon examination, it became quite clear why she had been turned away by other clinics: she was over -23D short-sighted. For those unfamiliar with eyesight prescriptions, more common short sighted prescriptions tends to be between -0.25D and -10.00D; the higher the number, the worse the eyesight. The picture shows a very rudimentary example of the eyesight of someone who is approximately between -8.00D. This patient’s uncorrected vision was almost three times worse than this!

The below prescription was found during initial suitability assessment:

SphereAstigmatismAxisVisual AcuityNear Vision
RE-23.50-0.501806/12N8
LE-21.00-0.751706/9-N6

Laser treatment is not available for such high prescriptions, but there is an alternative in the form an ICL (Implantable Contact Lens). Think of it as a micro-thin contact lens that is placed inside the eye (just behind the iris), rather than on the surface of the eye. It is made of Collamer which is a technologically advanced lens material that because of its collagen base, is 100% biocompatible and designed to function in harmony with your natural eye. There is no rejection by the human body, which means that ICLs can effectively serve as permanent contact lenses. They are available in powers up to -20D.

After careful counselling and assessment of pre-operative scans, our most experienced ICL surgeon Dr Goran Helgason (who has ICLs in his own eyes) chose to take on this case and carry out a partial correction for this patient. This means that the ICL would correct the majority of her prescription, but that she would still require glasses or contact lenses for the remaining prescription. The patient was more than happy with this recommendation. Patients with such high prescriptions often struggle with glasses because of the thickness and weight of the lenses. They also struggle with contact lenses as high powers are only supplied by a limited number of manufacturers and are unavailable in the disposable variety, causing discomfort during wear. The cost of such tailor made glasses and contact lenses are very high and although patients get a small contribution from the NHS, it is often not sufficient to ease the financial burden.

Surgery was carried out over two consecutive days. 1 week post-op check found the following results:

RE-3.75-0.751706/12N8
LE-1.25-0.501806/9+1N6

As it can be seen, the above residual prescription is much more manageable. Such a drastic reduction in the prescription made a huge difference to this patient’s quality of life and she was then able to wear glasses and contact lenses far more comfortably.
