Cataract Surgery with Premium Lenses - Multifocal and Sequential Lenses
What is a cataract and how is it treated?
A cataract is actually a clouding or clouding of the normally clear lens of the eye. Cataracts can cause vision loss to the point of blindness, blurred vision, sensitivity to light, glare, halos, decreased night vision, changes in color vision, and the need for more light for reading. Cataracts are treated with a simple, quick surgery under local anesthesia. During the operation, the cataract is completely removed along with the natural lens and an artificial lens is implanted inside the eye instead of the natural lens.
Is it necessary to implant a lens during cataract surgery?
Absolutely yes. It should be remembered that a cataract develops inside the natural lens of the eye. It is actually a clouding of the natural lens of the eye that gives us good vision. When we talk about cataract surgery, we mean removing the cloudy or opaque natural lens (cataract). That is, a cataract and the natural lens of the eye are not something different, but rather it is In fact, the natural lens of the eye is opaque and cloudy. Since the function of the lens is to give us good vision, if it is removed during cataract surgery, an artificial lens must be implanted in order to have good vision. So during cataract surgery, not only is the cataract removed, but the natural lens of the eye is also removed with it.
What lenses can be implanted instead of the natural lens during cataract surgery?
As mentioned, during cataract surgery, an artificial lens must be implanted inside the eye in order to have good vision after the operation. There are several types of lenses that can be implanted and produced by different local and international companies. There are monofocal lenses, which provide a single focus point (hence the name), multifocal lenses that provide multiple focus points for far, intermediate and near distances, and there are toric lenses that correct astigmatism (angles).
The main disadvantage of monofocal lenses is that this type of lens provides a single focus point (monofocal). The specific lens number creates a single focus point for far or near (for reading) but not both together. As a result, the patient will need glasses after surgery for near or far depending on the focal point of the chosen lens. If a lens with a focal point for far is chosen, the patient will see well at a distance without glasses but will need reading glasses. Conversely, if the patient chooses a lens with a focal point for near, he will see well at close range but will need glasses for distance vision.
What are Premium Lenses - Multifocal and Sequential Lenses?
Premium lenses are advanced lenses that provide an excellent solution for vision after cataract surgery. These lenses are multifocal lenses or multifocal and sequential lenses or sequential lenses only. Multifocal lenses are lenses that provide at least three focal points, for distance, computer distance and near. Implanting these lenses relieves the patient of wearing glasses after cataract surgery.
These lenses allow excellent vision at near and far after implantation without the need for glasses, and are therefore excellent for patients who do not want to continue with glasses, for near or far after the operation.
The second type of premium lenses is toric lenses. These lenses correct astigmatism (angles) at all distances, both near and far. Therefore, correcting astigmatism with these lenses helps to see better after cataract surgery.
The third type of advanced lenses is the serial multifocal lenses. These lenses provide at least three focal points, distance, computer distance and near, in addition to correcting astigmatism (angles) at all distances, near and far.
In people with astigmatism, these lenses allow for excellent near and far vision after implantation without the need for glasses.
How is cataract surgery performed by Dr. Nasser?
The cataract surgery performed by Dr. Nasser is without needles, without scars and under local anesthesia only. The operation is painless and has a quick recovery. The operation is performed in a private hospital and under local anesthesia with eye drops only. Sometimes painkillers are given before the operation to make you feel comfortable before the operation. You will be awake throughout the operation and will hear Dr. Orwa talking to you and his assistants. Dr. Orwa will continue to talk to you during the operation to reassure you. During the procedure, the cataract is removed from the eye and an artificial lens is implanted. There are no beads or needles during the procedure. At the end of the procedure, a transparent shield is placed over the eye to protect the eye but not cover it. You go home immediately after the procedure with clear instructions and an appointment for a check-up at the clinic the next day. Recovery from the procedure is rapid and you will regain your vision quickly after the procedure.
