Permanent correction of vision, removing the need for spectacles or contact lenses. (22)

What do we want from our vision ?

1. We want to open our eyes each morning and see clearly, at all distances, without spectacles or contact lenses

2. We want to walk around without spectacles or contact lenses.

3. We want to drive without spectacles or contact lenses.

4. We want to read without spectacles or contact lenses.

So the goal is for everyone to see everything clearly at all times and at all distances, without assistance from spectacles or contact lenses.

These days we have lenses that can be implanted permanently into the eye to correct the focus, so that you no longer need spectacles or contact lenses.

The lenses we have available today, for implanting into the eye, are far better than those available even a few years ago. Your lens can be chosen from any of a variety of lenses; for the information on the latest lenses available, please feel free to contact the St. Albans Eye and Vision Clinic on:

The operation is painless and highly effective. It safely and permanently removes the need for spectacles or contact lenses.

So we can now bring near-perfect vision without spectacles or contact lenses, to almost anyone regardless of age or spectacle-prescription.

How does this work ? - read on:

The normal eye that needs no spectacles or contact lenses:

So, in the normal eye, the rays of light from each point on the object being viewed converge to a single point on the retina which is the layer lining the back of the eye which detects the image.

The rays of light from different parts of the object are focussed to different points on the retina so that an image of the object is produced on the retina. In fact the image on the retina is upside down and back to front;
however, because the brain has all our lives "seen" objects upside down and back to front, it appears normal to us and we are able to use the image to interact accurately with our surroundings.

The most common cause of blurred vision is focussing error (= "Refractive error"):

Short-sight:

When people are said to be "short-sighted" (= Myopia) this is almost always because the eye is longer than normal so that the focus of light from objects is in front of the retina so that rays of light from each point on the object are spread over the retina in a "blur circle" which means that the image is blurred:

Long-sight:

When people are said to be "long-sighted" (=Hypermetropia = Hyperopia) this is almost always because the eye is shorter than normal so that the focus of light from objects is (theoretically) behind the retina. This means that, once again, rays of light from each point on the object are spread over the retina in a "blur circle" which means that the image is blurred:

Astigmatism:

Sometimes the focussing problem is not simple myopia or hypermetropia, but rather the transparent window on the front of the eye (the "cornea") is rugby ball shaped instead of the more normal spherical football shape. This is called Astigmatism, and it causes rays of light in different meridia of the image to be focussed at different distances:

Presbyopia (= age-related requirement for reading spectacles):

Even if our vision is clear when young, as we move towards middle-age the natural lens loses its elasticity and the eye becomes unable to see near things clearly without reading spectacles. This is called presbyopia.

Correcting the above refractive errors with spectacles:

All of the above refractive errors (myopia, hypermetropia, astigmatism and presbyopia) can be corrected with spectacles or contact lenses. These work by altering the directions of rays of light before they enter the eye, so that after the incorrect focussing mechanism of the eye has finished acting on the light, the rays of light are focussed correctly on the retina.

But, as discussed in the post two days ago, both spectacles and contact lenses cause certain problems and are therefore not ideal.

Lens implants:

The ideal situation is for everyone to see everything clearly at all times and at all distances, from the moment they wake each morning until last thing at night, without assistance from spectacles or contact lenses. The goal is a one-off treatment that will restore spectacle-free near and distance vision for the rest of a person's life.

And we can achieve this by implanting the lens/contact lens into the eye so it stays there permanently.

The operation has been refined over the last twenty years, and at the St Albans Eye and Vision Clinic, U.K. (tel: +44 (0)1727 812925, Email: contact@StAlbansMedicalCentre.com) is undertaken absolutely painlessly in a few minutes, under injection-free local anaesthetic.

Modern lens implants can correct for all the above refractive errors: Myopia, Hypermetropia, Astigmatism, Presbyopia.
Truly back to the vision of a young person, spectacle-free.
