The clouding of the eye lens, popular among people as a “veil” or “curtain”, has the scientific name cataract. It can be congenital or acquired. The congenital cataract is the result of anomalies in the development of the eye lens. It is rarely a hereditary disorder. Most often the congenital cataract is caused by maternal viral diseases, especially in the first trimester of the pregnancy. Children born with a cataract have low vision when the lens is partially opaque and loss of vision if the lens has a complete opacification. Such children should be operated as early as possible in order to have a normal intellectual development in the future. The acquired cataract arises in some systemic diseases (diabetes) or is due to eye injuries, radiation effects. It can appear as a complication of some eye diseases: inflammatory, such as iridocyclitis, uveitis and in some cases myopia. The most common type of cataract is the age-related one. It usually starts to form around the age of 60. Patients complain of decreased vision in one eye, rarely in both eyes. The decrease of vision is gradual and painless. Cataracts can be treated only surgically. After being diagnosed with a cataract, patients should have their vision and eye pressure checked every 3-4 months.
At an early stage of cataract development wearing spectacles often improves the eyesight. Some people, however, see better without spectacles at the beginning. At first sun-glasses can also help to reduce the increased sensitivity to light. Unfortunately, there is no medication that can cure your cataract.
At the stage when the lens is very dark your vision can be corrected only through cataract surgery. You, as a patient, choose the time for the operation. When you notice that the quality of your eyesight is not good enough for your everyday activities it means that the time has come. The cataract surgery is described in detail below. If anything is unclear feel free to ask your ophthalmologist.
Special intraocular lenses for astigmatism correction are already available. AcrySof TORIC lenses are the proven leaders in this field. They have been designed particularly for patients with cataract and corneal astigmatism.
Similarly to monofocal lenses this type of lenses ensures a qualitative distant vision and less dependability on spectacles. Most of the patients, however, still need glasses for reading and computer work.
AcrySof TORIC lenses correct astigmatism and offer a good quality distant vision. They have UV and yellow filtering against the blue light hazard.
The traditional intraocular lens implanted in the eye in replacement of the removed cataract recovers the clear vision but can not correct astigmatism. Spectacles or contact lenses or even an additional surgery are necessary for the correction of blurred and distorted vision.
1. Regularly visit your ophthalmologist on the scheduled days.
2. Take your medicines and apply the eye drops as directed.
3. Do not lift heavy objects (more than 15 kg) and avoid any intensive physical work during the first days after the operation. You can do your usual everyday tasks.
4. Driving is not contraindicated but it would be better if you avoid driving during the recovery period.
5. Avoid rubbing or pressing the eye at least one month after the surgery.
6. You can take showers and baths or shave yourself as usual but your eye must not be in contact neither with shampoo nor with soap. Be extremely careful when taking off your make-up.
7. Avoid reading longer than recommended in the first week after the surgery.
8. You can watch TV but be careful not to overwork your eye.
9. You can work on a computer although with some caution consistent with your condition during the first days after the surgery.
10. You should avoid steam baths, swimming, water jumps and cycling in the recovery period.
11. In case of whatever problems during recovery (such as redness in the operated eye, pain or worsening of your eyesight) immediately contact your doctor.
