Phacoemulsification of cataract with IOL implantation of any complexity

When is the lens replaced?

In the usual course, cataract progresses slowly, over several years, which reduces the vigilance of patients. For timely detection of the disease, it is important to visit an ophthalmologist in a planned manner. The doctors of our clinic examine the patient with the help of modern equipment, which allows to determine the cataract at the earliest stage of its formation, which improves the postoperative result.

The main indication for cataract phacoemulsification with IOL implantation is the presence of lens opacity. The purpose of the manipulation is to remove the old lens, unable to perform its function, to a new one - artificial, that meets all safety and efficiency requirements.

Types of intraocular lenses

1. Monofocal - Lenses give the usual monofocal vision for the eye. Monofocal vision will require the use of glasses for distance or near (depending on the patient's preference) in cooperation.
2. Multifocal - allow vision at near, medium and long distances. But for these lenses there are individual contraindications.
3. Toric - if there is astigmatism on the cornea, these lenses will correct it.
4. Deep focus (EDOF) - provide high visual acuity at far and medium distances. If you need near vision, you must use glasses, or when calculating the lenses, one of the operated eyes is taken away into a slight myopia.

All models of artificial lenses are equipped with an ultraviolet filter, protecting the eye from radiation.

How is the lens removed and then replaced?

Before manipulation, the patient is instilled with drops that dilate the pupil. This is necessary to provide surgical access to the lens.

The anesthesia team connects all the necessary sensors to monitor the general condition of the patient. A cubital catheter is placed to administer the necessary sedatives and painkillers.

Operation steps:

1. Local anesthesia is added with drops.
2. Viscoelastic is injected into the anterior chamber of the eye through microinvasive punctures - a substance that protects the inner layer of the cornea from damage.
3. Using an ultrasonic tip, the lens is softened under the influence of ultrasonic waves (ultrasonic phacoemulsification).
4. The substance of the lens and its masses are removed.
5. Polishing the capsule - preparing it for the implant.
6. Placement of a new artificial lens using a special injector that allows it to be inserted into a 1.8 mm self-sealing incision.
7. Viscoelastic is washed out.

Modern intraocular lenses are produced using the latest technologies - they are soft and able to take the desired shape themselves, unfolding inside the capsule. The incisions made during the operation are self-sealing, micro-invasive (MICS), so suturing at the end of the procedure is not required.
