Intra-Ocular Lenses for Visually Impaired People

The IOL systems have been developed to provide patients with macular disease an improvement of their central vision.

ViP: In this exciting new procedure, two small lenses are inserted into the eye. Together, these lenses act like a telescope, slightly magnifying the image and diverting it to a healthier part of the retina. This healthy retina takes over the role of the macula and can give the AMD patient significantly improved vision.

Prices for all inclusive is £5900 per eye.

LMI IOL: Using a system of mirrors to project the image to a healthier part of the retina, this sophisticated lens implant has the advantage of using only one lens (thus not altering the anatomy of the eye) and the benefit of higher magnifications!

Prices for all inclusive start from £9000 per eye

Usually only one eye is required to be treated.

We offer FREE Consultations for anyone who would like to be assessed for these lens implants!

The procedure takes about 30 minutes

There is no need for overnight stay in hospital

The potential improvement in vision can be tested using a special simulator. The simulator demonstrates the effect of the IOL-Vip/LMI system so patients can experience the possible improvement before the operation. Patients are helped to learn to use the new image with the help of some simple exercises.

The IOL-Vip or LMI systems can help patients with “dry” and established “wet” forms of AMD and also patients with other forms of macular disease including macular holes, myopic degeneration, and hereditary retinal diseases e.g. Stargardt’s, Best’s.

How does the LMI work?

The main concept of the LMI is based on the use of an intraocular implant with mirrors that modifies the central image while preserving the peripheral vision, for redesigning vision on the human retina and treatment of retinal diseases.

The LMI is designed to be a surgeon-friendly implant, making it easy to implant by an average cataract surgeon. The modification of the central image does not depend on the change in the index of refraction.

The use of mirrors provides us with flexibility that cannot be achieved by using only lenses. By implanting mirrors inside the eye we can divert the light in any way we want and thus create magnification and control the central visual
field (increase it or decrease it).

The use of mirrors as optical elements is very common in many instruments, including astronomic telescopes. The main concept of optically treating patients suffering from AMD is creating a magnified image on the retina so that the image falls on a larger area than the damaged area of the diseased retina.

The brain receives the information after an increased image is created on the retina. In AMD, while most photoreceptor cells on the macula are not functional and cannot receive light, some photoreceptor cells are still alive and functioning.

By increasing central visual field by two times to three times magnification on the macula, we are able to use enough cells in order to create an image that can be seen by the patient (see exhibit below).

Macular Hole Treatment

Planning macular hole treatment in good time is often the best way to ensure improvement or recovery of this condition. Depending on the severity of the problem there are a couple of options for macular hole treatment including surgery when the problem is very advanced or by way of an injection into the eye when the issue is first identified. Some opthamologists may choose to wait a while before determining the best course of action. A macular hole won’t get better in isolation but the condition also is not painful so seeing how it develops could help decide the best macular hole treatment.

Macular Hole Surgery

Macular hole surgery is a path to consider for those suffering loss of vision, blurriness or distored vision from this problem. A macular hole won’t get better on it’s own and over time the issue is likely to worsen. In some case the quicker treatment is carried out by way of macular hole surgery or other options the better. Depending on the size of the hole it is possible that macular hole surgery could stop the degeneration of vision and could even help to restore sight in some cases. Discussing treatment options with a specialist in eye care could be useful to assess the best course of treatment.
