Cataracts, Complications, Rezoom and Restore
Cataracts are a gradual yellowing and opacification of the natural lens inside the eye. The most common type is senile or a result of the nuclear variety, and called by the high absorption of light energy in a period of years. The natural lens is composed of an alpha-protein, which is clear. High-energy light causes a chemical reaction that transforms this protein alpha, a beta-protein, which is yellow. Over time, as the goal is more yellow, it bends slightly as it travels throughthe goal. Ultimately prevented the transmission of light and vision. It is at this point that people are trying to take into account the eye cataract surgery. Other types of records are the Qatar-induced trauma, drugs, and some are congenital.
Cataract surgery today is far superior to what is done, even 10 years ago. Today, a small incision in the temporal aspect of the cornea is made, the natural lens is removed. An implant inserted into the eye through this opening.Complications at this point, a bad cut through watery fluid loss and disruption of the natural lens. These are the results of protein floating around the lens of the eye causing iritis, which is an internal inflammatory reaction. This is treated with steroid eye drops. During the healing process will be longer, the long-term prognosis remains unchanged.
The last intraocular implants in contrast to the older, are multifocal. This means they can see the patient, bothDistance and closeness, as they did when they were younger, they are. The ReZoom lens and restore implants are used frequently. They operate on the principle of multiple images, projected on the retina, and allows patients to see at all distances. They are very similar to the old-fashioned as the Echelon bifocal contact lenses. The ReZoom has a central area close to the distance of the surroundings. The restoration is the opposite. The central area is large, while the surrounding areas are also nearby. ClinicalPractice is not demonstrated either better than others for the average patient.
However, the same problems arise with the Echelon bifocal lens. The first is that glare, especially at night, is a nuisance. The second is that they usually look for some victims in the area. The third complication is that the system must be perfectly positioned in the center of the pupil. The implant may move many times, as the eye heals, and if the "sack" that keep the brakes slow the systemalso move. Each of these movements lead to vision loss and, sometimes, because seeing double vision. Some surgeons have begun to take sewing to prevent the movement of the plant.
In short, the concept is acceptable to these plants, but in practice I found that most patients require glare and poor visibility complain glasses for distance, near, or both. And 'the side effect of double vision, glare and disturbing that most of the people. If you consider that most cataractpatients are seniors, and are less tolerant of these visual affects, one must think long and hard if they are willing to take a chance on these multifocal implants. As a side note, the best results with them have been to use a Rezoom in one eye and a Restore in the other.
With cataract surgery so far advanced, the best results seem to still be using a single vision distance implant and using reading glasses after surgery.
