Cataracts are the most common reason for patients to seek medical help with vision problems.
Today, the main pool of patients of each ophthalmologist is patients diagnosed with cataracts, because:

There are technologies and modern equipment for cataract surgery using a seamless method;
It is possible to use intraocular lenses (IOL), which allow solving various problems related to vision at different distances, astigmatism, etc.

This entire arsenal allows today to perform microinvasive operations with 2 mm access, which do not require suturing.

The most important advantage for the patient is a quick rehabilitation period. Some patients come to us in the morning for cataract surgery and on the same day after surgery, in the evening they drive home on their own.

What is cataract?

Cataract is a clouding of the natural human lens.

Our lens is an anatomical area of ​​the eye that does not receive nutrition from the vessels, as is usually the case. All metabolic processes occur in it due to the circulation of its own fluid in the eye cavity.

This is a fairly slow process. Therefore, over time, the lens loses its elasticity. Patients who have never had vision problems begin to see poorly up close. When metabolic processes in the lens slow down, we lose the ability to read well or distinguish small details in front of us and put on "plus glasses".

Accommodation is best developed in drivers, as they are constantly focusing on different objects at different distances and plus looking at the dashboard.
The lens is a jelly-like substance. The ligaments that hold it are fixed to the ciliary muscles. When we look close, the muscles tense the lens, it increases, and we, with the help of this telescopic system, can see objects close up. When we look into the distance, the ciliary muscle relaxes, the lens flattens, and we can see into the distance.
 This is called accommodation.

When is it time to have cataract surgery?

The patient may begin to see the first opacities in the lens as a light haze, fog. Over time, this effect intensifies, the cataract becomes mature, and the patient stops seeing.

Since this sensation of "haze" is typical for many diseases, any time it appears, you need to contact an ophthalmologist to make a diagnosis at an early stage.

The sooner the diagnosis of cataract is detected - and the sooner it is operated on - the lower the intraoperative risks, and as a result, the shorter the rehabilitation period.

All over the world, cataracts are operated on using ultrasound, which destroys the clouded lens. The denser the lens, the more ultrasound is needed to remove it. This creates a high risk of affecting other anatomical areas of the eye.

Depending on the degree of clouding of the lens, federal guidelines for cataract surgery recommend replacing it with a vision loss of 50% or less.

But in my opinion, if a patient sees 60% and 70%, he may be offered surgery if such vision significantly reduces the quality of life.
