Cataract is a condition that occurs when the natural lens of the eye, which provides vision and is located behind the pupil, loses its transparency and becomes cloudy. In other words, it leads to impaired vision that can be described as looking through a foggy window.
Symptoms of cataract;
Cataract is not a disease that can be treated with medication or glasses. There is not an effective method which can stop the progression of cataract and a formed cataract can only be treated with surgery. Thanks to modern techniques, today cataract operations are performed with a pain-free procedure without using needles or anesthesia, and patients can return home on the same day. There are some important points that need to be considered in relation to cataract surgeries. The experience of the doctor and the quality of the lens implanted into the eye directly affect the success of the surgery. After a surgery performed using poor quality lenses, problems may develop in the eye. This may also result in the risk of developing cataract for the second time after a short period. For patients, this means risk of another surgery and additional costs.
Congenital cataract is a unilateral or bilateral clouding (opacification) of the lens that is present at birth. Congenital cataracts may develop due to infections the mother had or the medications she used during pregnancy or with no apparent cause. One pupil being a different color from the other (white) or crossed eyes (strabismus) can be a sign of cataract. Once such symptoms are observed in infants, an ophthalmologist should be consulted without delay. If a congenital cataract hinders vision and particularly if it is unilateral, surgery should be performed as soon as a diagnosis is made. A specialized ophthalmologist decides on the timing of surgery after a detailed examination. The most important problem in an eye with congenital cataract is lazy eye (amblyopia). In order to overcome amblyopia, surgery should be performed as soon as possible in accordance with the ophthalmologist’s advice.
An eye will regain its former vision after the cataract surgery unless there is another factor besides cataract that impairs vision.
The diopter of the intraocular lens implanted in the eye during cataract surgery can be determined for a clear far or near vision. So the person undergoing the surgery will have a clear far vision if the lens is set to correct far vision, but glasses for near vision will be necessary. If the eye becomes myopic with the lens implanted during the surgery, the person won’t need glasses for near vision but glasses will be necessary for far vision. If a multifocal lens is preferred, myopia, hyperopia and astigmatism can be corrected with a single lens.
No. You can have the surgery at any stage of your cataract from the moment cataract develops and your vision starts to get impaired.
Yes, problems are more likely to occur in surgeries for very advanced cataracts. Also, the operation lasts longer in cases of advanced cataract.
General anesthesia is only given in infants and pediatric patients for cataract surgery. Different types of local anesthesia are used for adults in cataract surgery. An injection is made beside the eye to numb it and prevent eye movements.
You can have laser surgery if your eye is found to be suitable in the examination.
Amblyopia is not corrected by cataract surgery. There are different treatments for amblyopia.
This examination is performed by dilating the pupil with an eye drop and can reveal the signs of many conditions such as retinal detachment, glaucoma, hypertension, brain tumors and other diseases.
