Cataract – a disease in which there is clouding of the eye lens, and a person begins to see through a cloudy film. Over time, the disease progresses, and if untreated, complete blindness can occur. Cataract is one of the most common age-related eye diseases. But more and more often, cataract are found at a routine examination in young patients – it develops without symptoms on the periphery of the lens. Therefore, it is important to regularly undergo ophthalmological examinations in modern medical centers, where the equipment and competence of doctors can determine the disease at an early stage, which means that the necessary treatment can be started on time.

Replacing the lens with a soft intraocular lens is the only effective way to permanently get rid of cataract and restore full vision. Such an operation in the SvetoDar clinic takes 10-15 minutes – without suturing, with a small puncture. The very next day, the patient may notice that his natural vision begins to return to him, and after a month it reaches its greatest acuity.

What is cataract?

The lens of the human eye is a “natural lens” that transmits and refracts light rays. The lens is located inside the eyeball. Initially, it is transparent and elastic. With cataract, a partial or complete clouding of the lens occurs, its transparency is lost, and only a small part of the light rays gets into the eye, so vision decreases, a person begins to see not clearly and blurry. Over the years, the disease progresses: the clouding area increases and vision gradually decrease, up to blindness.

«Kataraktes» in translation means a waterfall. With cataract, vision is blurred, and a person sees, as if through falling water or through the misted glass. With the development of the disease, flickering in front of the eyes of stripes, strokes, and spots is felt more and more, photophobia and double imaging appear. Often there are difficulties when reading, writing, working with small details. As cataract «mature», the color of the lens becomes white instead of black.

Causes of cataract:

  • age;
  • genetic disposition;
  • eye injuries (chemical, mechanical, contusion injuries);
  • various eye diseases (including glaucoma, and high degrees of myopia);
  • endocrine disorders (metabolic disorders, sugar disease, vitamin deficiency);
  • radiation, microwave and ultraviolet radiation;
  • prolonged use of a number of drugs;
  • increased radiation;
  • adverse environmental conditions;
  • toxic poisoning;
  • smoking.

Surgical cataract treatment

The gain of vision is the main goal of surgical treatment. The operation is necessary only with such a degree of cataract development when the patient’s capabilities in everyday life are reduced: driving a car, working, reading, watching theater and cinema, etc.

Cataract phacoemulsification is the most advanced ultrasound cataract treatment technology. Phacoemulsification lasts 10 to 15 minutes. As a result of the operation, the lens, with a developed cataract, is replaced by a soft intraocular lens. With phacoemulsification, a small incision is made of 2.5 — 3 mm in the cornea. Under the action of ultrasound, the substance of the cloudy lens is destroyed and removed from the eye. A transparent artificial intraocular lens in the folded state is inserted through a micro-incision into the place of the removed lens. The lens straightens itself and takes the place of a natural lens. The micro-incision through which the operation was performed does not require suturing, which can significantly reduce the recovery postoperative period. The patient sees quite well several hours after phacoemulsification, and the maximum visual acuity is restored for a period of up to 1 month.

Extracapsular cataract extraction is an older technique, which is carried out with a large incision of the cornea and suturing. Considering that the sutures remain for 6 months, the rehabilitation period takes a rather long time and requires restrictions on physical activity, vision is restored much more slowly.

The longer the patient does not have cataract operation, the slower the eye recovers after operation and the risk of complications increases!

What kind of intraocular lens should be chosen?

After cataract operation, an artificial lens (intraocular lens) is implanted in place of a cloudy lens. Before the operation, all patients undergo a full diagnostic examination of the entire vision system. Based on the data obtained during the examination, and based on the anatomical and optical characteristics of the eye, the doctor individually calculates the refractive power of the lens for each patient. Be sure to take into account the patient’s age, occupation, wishes. The clinic offers a wide range of lenses that are fitted for each patient individually. Thus, it is possible to choose lenses that will not limit the usual active lifestyle.

I-Medical (Germany) is a spherical acrylic hydrophilic lens with standard properties.

Akreos™ Adapt AO (Baush&Lomb) is an aspheric lens that automatically adapts to any eye size and delivers exceptional visual quality and contrast sensitivity thanks to advanced aberration-free optics

Akreos™ MI 60 (Baush&Lomb)is also an aspheric lens that delivers exceptional visual quality and contrast sensitivity thanks to advanced aberration-free optics. This lens is designed for operation with the smallest incision (only 1.8 mm!)

AcrySof® IQ (Alcon) – an “intelligent” lens, the world’s best artificial analogue of the natural lens! Corrects spherical aberrations (flecks, glare, halos) in bright light. Gives high-quality vision in all lighting conditions. This lens is almost twice thinner than a traditional one and is installed through an incision of only 1.8 mm. It contains not only a UV-filter, but also the Blue light filter.

Unique premium lenses

AcrySof® Toric (Alcon) – if you have astigmatism, you previously prescribed complex glasses with cylinders, then the only way to extract cataract and cure astigmatism in one step is to set up this TORIC lens. This lens is the best choice for good distance vision with astigmatism!
AcrySof® ReSTOR (Alcon) – MULTIFOCAL lens. The latest revolutionary development. Its huge practical advantage is the provision of high-quality vision after operation, both in the distance vision and in the near activity. When setting all other lenses after operation, distance vision increases and glasses are required in the near activity. If you want to see both in the distance and near without glasses – this lens is for you.

This is the world’s only system that allows cataract extraction through a 1.8 mm micro-incision, while before that 2.5-3 mm were considered the norm. Thus, the invasiveness of a surgical operation is reduced by 20% and allows patients to significantly reduce the period of recovery of vision.

The new six-crystal ultrasound tip allows to quickly remove even the densest cataract the most sparingly for the patient’s eye.

A flexible platform with unique capabilities allows to effectively use the latest technology in cataract phacoemulsification and get excellent results.
Ideally balanced system for applying both standard coaxial technology and 1.8 mm coaxial or biaxial MICS technology.

Postoperative patient alert card

An artificial lens has been implanted. Within 2 months after operation, your eye will require treatment and follow-up care, and visual acuity will gradually increase.

  • It is necessary to instill drops prescribed by the doctor into the operated eye. Drops can be instilled independently in front of a mirror or your relatives can do it. First, you need to wash your hands, pull the lower eyelid and instill 1 drop of the medicine. In this case, you need to look up.
  • Daily fresh air is required.
  • There is no special diet. Alcoholic beverages must be excluded.
  • During washing, do not touch the operated eye.
  • 5 days after operation, you can take a warm shower.
  • It is advisable to sleep on the back or on the other side.
  • It is prohibited doing housework in an inclined position and lifts heavy objects.
  • You can do gymnastics, excluding exercises with inclination, tension, running, jumping.
  • On the street, the operated eye should be covered with a bandage for 1-2 weeks after operation.
  • You can watch TV, go to the theater, shop. The first 2 weeks it is recommended to limit yourself to reading.
  • According to indications, glasses may be issued to you 2 months after the operation.
  • ATTENTION! In cases where emergency assistance is required (a sharp decrease in vision, redness, pain, etc.), you should immediately consult an ophthalmologist.
