According to statistics from the World Health Organization, cataracts - also known as cataracts - are the most common cause of blindness in the world, and affect nearly 40% of men and 45% of women over 74 (after tourmedica). The immediate cause of cataracts is the gradual clouding of the lens and the associated lower light transmittance, which results in a progressive deterioration in the quality of vision. - Many people in the first stage of the disease confuse cataracts with common vision defects, such as short-sightedness or farsightedness. The reason for this are similar symptoms, i.e. gradual worsening of near and far vision, and blurring of the image. Unfortunately, in the case of cataracts, it is not possible to effectively correct incorrect vision, e.g. with the use of glasses or lenses - Dr. Karol Korżel from the ophthalmology clinic told the portal dziennikpolski24.pl.
Tufted cataracts - causes and treatment
In ophthalmology, there are several types of cataracts, and the division concerns, among others the patient's age, immediate causes of the disease or the location of the changes. One of the clinically most difficult cases is the so-called Tufted cataracts, a type of disease that results from the dislocation or subluxation of a lens, usually due to mechanical trauma. It occurs in situations when the ciliary rim and the ligamentous apparatus break, which are responsible for the location of the lens. If it is damaged, it can, for example, get into the anterior chamber of the eye and cause very serious glaucoma. In most patients, the torn up lens gradually loses its properties, transmits less and less light, and vision deteriorates all the time.
The treatment of a subcutaneous cataract involves removing the damaged lens structure and implanting an artificial intraocular lens in its place. This procedure is performed using a special ultrasonic tip, which is called phacoemulsification. Its main advantage is that it requires only a small incision (1.5 to 3 mm wide) and is performed under superficial anesthesia in the form of drops or gel applied to the conjunctival sac. In place of the removed lens, the doctor introduces a foldable artificial lens with high flexibility. Thanks to this, it can be placed in the eye without widening the cut. When inserted into the eye, the lens develops and takes the place of the removed natural lens.
The power of the implanted lens is calculated before the surgery based on the previous eyeball measurements. As a rule, the doctor selects such parameters that the patient can function normally every day, using only reading glasses. In private clinics, however, there are already much more modern artificial lenses that allow patients to have excellent vision both from near and far, and even correct astigmatism. However, they are much more expensive - they cost even about 2-3 thousand. PLN, while the monofocal lens most commonly used in the treatment of subcutaneous cataract costs from 150 to 450 PLN.
Tufted cataract treatment with phacoemulsification is performed as part of the so-called surgery one day, which means that a few hours later the patient can leave the hospital. A small cut does not require suturing and allows for quick recovery. For about 2-3 weeks after the procedure, use eye drops prescribed by your doctor, and for about 2 months - avoid lifting heavy objects and very violent shocks.
