Cataract is eye lens clouding, which leads to decreased penetration of light rays and reduced visual acuity. In most cases, cataract is an age-related pathology. However, the disease can also be diagnosed in children as congenital or develop at any age due to a trauma, inflammation or general pathology.

The only possibility to eliminate the pathology is a microsurgical procedure consisting of removal of the clouded eye lens and replacing it with an artificial lens (IOL).

Currently, the Eye Microsurgery MNTK uses an advanced method of sutureless surgery when cataract is removed using the ultrasound phacoemulsification method and an artificial lens is implanted through an ultra small incision or the cataract is crushed with a laser with subsequent suction of lens fragments. In such surgeries the incision is so small that it does not required suturing.

At present, the Eye Microsurgery MNTK uses advanced femtosecond technologies to carry out key stages in cataract surgeries.

Most stages of the cataract surgery that have been previously performed by a surgeon, now are taken over by a femtosecond laser system. The laser makes a corneal incision, circular capsulorhexis and crushes the lens.

Advantages of a femto laser are:

  • remote (without surgical tools) destruction of the lens, which helps to avoid numerous complications
  • unparalleled accuracy of performing the main stages of the surgery.
  • safety of the surgery with predictably high functional results.
  • ability to ensure the ideal and stable position of modern models of artificial lenses for many years.
  • reduction of the rehabilitation period to several hours, which makes it possible to conduct such operations on an outpatient basis.

In some cases, when phacoemulsification or laser removal of cataract is impossible, the surgeon uses other methods of removing the cloudy lens, when the surgical incision is sutured with a special superfine filament.

The Eye Microsurgery MNTK has accumulated a vast experience of surgical procedures for cataract, with over 1 million surgeries carried out for 20 years. Thanks to the works of S.N. Fyodorov and his school, the procedures have become available to many patients all over the world and their prospects have been determined for the coming decades.


Continuous improvement of the cataract phacoemulsification technology, bringing of new models of intraocular lenses and surgical tools into clinical practice have made the cataract surgery a safe, highly effective and predictable method of treatment, which practically does not affect the patients’ ability to work. The modern cataract surgery technique ensures the maximum visual functions on the first day after the operation.

Removal of uncomplicated cataracts or cataracts in combination with an eye pathology is carried out in case of lens clouding that reduces the vision. - The total time required for treating one eye is 3-5 days (depending on the severity of the initial eye condition). - Preoperative examination – 2 days, surgery – on the 3rd day. - Postoperative follow up – 3-4 days. In case of cataract on the other eye, the decision on the term of surgery is made taking into account individual characteristics of the disease.

This type of surgery can be performed out-patiently and the patient can leave the clinic 2-3 hours after the surgery, accompanied by the relatives.

During the surgery, we use imported materials and implant soft intraocular lenses made in Europe or America, which helps to avoid suturing at the end of the surgery.

The procedures are performed by highly qualified surgeons of the eye lens surgery and intraocular correction department using cutting-edge equipment of the best world manufacturers.

In the surgical room, you will be attended by a surgeon, his/her assistant, an operating room nurse, an anesthesiologist and a nurse anesthetist. The modern anesthetic methods used by the Eye Microsurgery MNTK make the procedure absolutely painless. A cataract is removed under an operating microscope. In our clinic, patients stay under the surgeon’s supervision for 1-2 days, which we consider necessary to reduce the risk of postoperative complications. The visual acuity of an individual patient depends on the concurrent pathology, which is often revealed at the stage of preoperative diagnosis. There is a number of diseases when a perfectly conducted surgery will not give high vision acuity (e.g., glaucoma, central chorioretinal degeneration, diabetic retinopathy, retinal detachment, retinal vascular pathology, corneal opacity, etc.).

In a small number of patients clouding and decreased vision due to lens capsule opacity may be observed 1-2 years after the surgery. This condition is called a “secondary cataract”. In this situation, you should visit your doctor, who will easily establish the reason for such vision impairment. A secondary cataract can be removed without a surgery during one session by exposure to a special impulse laser. The procedure is performed out-patiently and practically guarantees the restoration of vision.

The dissection of a secondary cataract with a laser is performed in case of the posterior capsule opacification after surgical treatment of cataract on aphakic or pseudo-facial eyes. - The total time needed for treatment is 3-5 days. - Preoperative examination – 1 days, surgery – on the 2nd day. - Postoperative follow up – 1-27 days.

The most important factor of the successful surgical outcome is the adherence to all prescriptions of the surgeon and timely visits to a surgeon and ophthalmologist for examination at the place of residence.
