Cataract symptoms and causes
The causes of cataracts:
Cataracts, also known as cataracts, are the most common eye disease leading to a significant deterioration in visual acuity. Tens of millions of people worldwide suffer from cataracts. The cause of age-related cataracts is clouding of the lens, resulting from changes in chemical composition and disturbance of the lens structure. Cataracts most often develop with age and are called senile cataracts.
- deterioration of visual acuity
- difficulty reading and watching TV
- disturbance in the assessment of distance
- blurred vision
- difficulty with moving and self-service (applies to the elderly)
Cataracts do not cause pain, itching, redness or watery eyes. The symptoms of the disease depend on the severity of the disease and may include changes in both eyes, although their progression may vary.
Types of lenses
The standard single vision lens provides excellent close-up vision, but requires additional eyepiece correction to see objects further away and at intermediate distances. The STANDART lens is intended for those people who will not mind wearing glasses after the surgery.
A lens that provides excellent vision both at a distance and at intermediate distances, but requires additional correction for seeing objects in close proximity. The COMFORT lens is especially aimed at those who want to be independent from glasses in everyday situations, such as shopping, driving a car or using a mobile phone.
A multifocal lens that provides excellent vision at all distances (i.e. close, far and intermediate distances) and no additional eyepiece correction is needed. The Premium lens is ideal for active people who want to achieve the comfort of life without glasses.
Description of the procedure
The procedure is performed under local anesthesia and takes an average of 20 minutes. A special device called a phacoemulsifier is used to remove the cloudy lens. Thanks to it, through a very small incision, you can crush and remove the cloudy lens, and replace it with an artificial one. The artificial lens is implanted inside the eye, in the natural position of the own lens. The material from which it is made does not risk being rejected by the human body and serves the patient for the rest of his life.
Artificial lenses offer great opportunities for correcting vision defects while removing cataracts. Appropriate fitting of the artificial lens significantly improves the comfort of life after the procedure.
