Intraocular Telescopes

Procedure for Age Related
Macular Degeneration (ARMD)

Macular degeneration (ARMD) causes scarring of the macula, the spot on the retina (the back of the eye) where images are focused. This scarring prevents images from being interpreted and sent to your brain.

The Intraocular Telescopic Lens procedure aims to improve vision in patients suffering with ARMD.

The IMT lens

The Implantable Miniature Telescope (IMT) is the latest development in AMD treatment. IMT is a more powerful lens than the IOLVIP, making it particularly helpful to enhance your ability to read small print.

The IMT has recently passed the stringent assessment of the US Food and Drug Administration (FDA) and Mr Moriarty has been selected as the first ophthalmic surgeon to introduce this innovation to the UK and Europe.

However, the IMT may not be the most appropriate option for some patients, in which case the IOLVIP would be carried out.

Mr Moriarty will discuss the most suitable telescope for your condition with you during your initial consultation.

How the IMT procedure works

The eye's natural lens is removed and replaced with the Implantable Miniature Telescope (IMT) lens. The IMT magnifies central vision so it fills a larger part of the retina. This reduces the impact of scarring on the macula and restores central vision.

Dear Mr Moriarty, I felt I must put in writing my gratitude for the operation on my eye and the care and concern you have shown to me. One of my happiest pastimes is reading, which I had not been able to do. It may be hard to understand the thrill of reading a book without recourse to magnifying apparatus. Sheer heaven!.....You have given an 87 year old her joy in life again for which I am eternally grateful".

Bloomin marvellous! I can read recipes without a struggle. I've got my confidence back. Mind you, I don't like the extra wrinkles I can see after the operation!

The IOL VIP lens

The Intraocular Telescopic Lens procedure using the Intra-ocular Lens for Visually Impaired People (IOL VIP) can help both types of ARMD. It can also help patients with macular holes, myopic degeneration and hereditary retinal diseases e.g. Stardardt's Best's.

The procedure can improve vision in these patients by magnifying and diverting the image to an unscarred part of the retina. Mr Moriarty was the first British surgeon to implant the IOLVIP (Intra-ocular lens for visually impaired people) lens and is Specialist Advisor to NICE for this procedure.

How the IOL VIP procedure works

In the operation, the natural lens is removed (as in a normal cataract procedure) and replaced with two artificial lenses; one in front and one behind the iris. This combination produces the same effect as a refracting telescope, and diverts the light coming into your eye to an unscarred part of your retina.

What to expect

The improvement is not immediate. Vision slowly improves as your brain adapts and best vision will come about 6 weeks after the surgery when your glasses are changed by your optician.

After the operation

  • There is no need for an overnight stay at the hospital.
  • You will be reviewed after one week, again after four weeks and as necessary subsequently.
  • Eye drops are usually required for three weeks after surgery.

Mr Moriarty recently wrote an article for Optometry Today that explains the technical details behind how the Implantable Miniature Telescope and IOL VIP procedures work.
