Intraocular lens

There have been tremendous technological advances in intraocular lens design over the past few years. The Vision Practice ensures that our patients benefit from these new technologies by offering a full range of intraocular lenses. Different lens types can be chosen to deliver the best possible vision following surgery. In the past, cataract surgery and refractive lens exchange procedures have been performed using only single focus lens implants. While this choice is still suitable for many, other types of recently developed implants can offer significant advantages. Intraocular lenses are commonly made of rigid or foldable materials although rigid materials are not suitable for use in small incision surgery. The Vision Practice uses lenses manufactured from hydrophobic acrylic which is a foldable material with a very long track record of safety. Your consultant will help you choose the best lens option for you, a process which will involve matching the lens design to your requirements, taking into account the biometry data. Four different designs of lens are offered by The Vision Practice:

AcrySof Single Focus
This lens can correct long and short sight, although not in the presence of significant astigmatism. In individuals without significant astigmatism, it can deliver good distance vision without glasses. In most instances, reading glasses will be needed for close work.

AcrySof Natural
This lens has a subtle yellow pigment within the material of the optical component of the lens. The yellow hue of the lens more closely matches the colour of the natural human lens and filters out some potentially harmful blue light. There is good theoretical evidence (although not absolute proof) that blue light filtering may protect against the development or progression of age related macular degeneration. This condition can lead to loss of central vision in later life, which can be quite profound. The lens does not alter colour perception significantly.

AcrySof Toric
The optical element of this lens contains correction not only for long and short sight, but also astigmatism. In the past, astigmatism in cataract surgery or refractive lens exchange procedures was corrected by additional incisions on the eye. With Toric lenses, no additional incisions are required. Astigmatism can also be corrected more reliably than by performing additional incisions which can sometimes give unpredictable results.

ReSTOR Aspheric Multifocal
The ReSTOR lens can deliver clear distance and reading vision without glasses. It can correct long and short sight but also has multifocal optics to restore the ability of the eye to adjust its focus for both near and distance vision. The ReSTOR lens used by The Vision Practice is the most advanced version of this lens available. It features newly developed aspheric optics, delivering the best possible visual clarity. The ReSTOR lens works best when implanted into both eyes.
