ACCOMMODATING LENS
(HUMANOPTICS 1CU)
For the correction of near and distance visual acuity.
THE ACCOMMODATIVE LENS
In the search for innovation and continuous surgeon and patient satisfaction, Human Optics AG has developed an artificial lens capable of replacing the natural crystalline lens and maintaining the accommodation effect.
The accommodative lens represents the latest development in artificial lenses and can provide patients with a better quality of life. The lens is designed to change shape providing similar functions to a natural healthy lens.
THE NEW WORLD OF INTRAOCULAR LENSES
The launch of the Accommodative Lens represents an important date for modern Ophthalmology. This unique and exceptional lens offers a solution to accommodation. The artificial implant is capable of focusing near and distant objects on the retina. Clear vision is no longer a matter of age but innovation and technology. The Accommodative Lens provides new youth to the human eye.
The Accommodative Lens has been
successfully implanted around the world since June 2000. Dr. Maritz was the
first surgeon to implant this unique lens in South Africa.
THE PRINCIPLE
A healthy natural lens is able to accommodate (change shape), so that objects at various distances can be seen in focus. Most artificial lenses are rigid and cannot change shape, therefore patients will generally need to wear eyeglasses after cataract surgery. Accommodation occurs when the ciliary muscle contracts to release the resting zonular tension. As a result the lens system which consists of the crystalline itself and the surrounding lens capsule becomes more spherical with increased suface curvature creating a change in optical power, so that near objects can be brought into focus on the retinal plane.
When accommodation ceases, the reconfiguration of the ciliary muscle increases the diameter of the lens capsule in the equatorial plane and far objects can be focused on the retina.
IMPLANTATION
After surgical removal of the cataract the implantation of the artificial lens is simple and uncomplicated. Small incision (3.2mm) and standard delivery methods are used to fold and place the lens in the capsular bag. All the lenses implanted are well positioned and centered with no location or vaulting.
WHAT IS A CATARACT?
A cataract is a clouding of the natural lens that can cause vision problems. The lens situated inside the eye can become more and more cloudy, preventing some light from reaching the retina.
The natural aging process is the main cause of cataracts. Conditions such as diabetes or eye injury can also result in the formation of cataracts.
Cataracts develop over a period of months or years and commonly effect both eyes, although not necessarily at the same time. Distance vision is the first to be effected and as the lens becomes more cloudy and rigid close vision can also deteriorate.
In the early stages, vision can be improved with spectacles or by using stronger lighting. If or when this is no longer sufficient for a normal lifestyle, surgery is the only effective treatment.
CATARACT SURGERY
During cataract surgery the natural cloudy lens is removed and is generally replaced with an artificial intraocular lens (IOL).
Cataract removal is one of the most frequently performed operations and is considered one of the safest and most effective.
The procedure can be done under a local or general anaesthetic depending on the recommendations of the specialist and usually patients can return home the same day.
CONCLUSION
The accommodative artificial lens gives excellent results for distance, intermediate and near vision with generally no requirement for added visual correction.
