Disorder in night vision
The only way of treating cataract is the surgery. It is not a disorder that can be treated with medication or glasses. There is not an efficient method that can stop its progress. Cataract surgery uses PHACO method performed with laser and known as an unsutured surgery. The intraocular lens which loses transparency is melted with ultrasound with the phaco method and a foldable intraocular lens is placed instead. During the cataract surgery, Viscoelastic Gel, a special liquid, is used. It is ensured with this gel that the natural lens be separated from the other layers of the eye without any damage. It is designed for a single use though it is specific to each patient. The cataract surgery is performed in operating room conditions and with special operating microscopes. It is mostly performed non-surgically with drop anaesthesia and without any pain and sutures and the patient comes back home on the same day. The surgery on a single eye is completed within about 10 minutes.
Multifocal Intraocular Lens
There are various rings in these lenses. Some of these rings enable distance vision and others enable near vision. Thus both distant and near images clearly fall on the yellow spot in the eye enabling us to see and distance and near visions can be clearly enabled. Selection of patients is quite important for this treatment. Expectation of the patient after the surgery and that near vision or distance vision is important for the patient should be paid attention. The purpose of multifocal intraocular lenses is to both eliminate cataract and find a solution for the near and distance vision problem at the same session in patients who have to undergo a cataract surgery. The applied surgical method is same as the standard cataract method. As a result of a detailed examination on the patient, determining the state of suitability for such a surgery is the most important stage of a successful surgery. The professional status, age, social life, habit of reading and daily activities of the patient are of importance for the selection of the patient.
