Trifocal Lens



What is an Trifocal IOLs?

Trifocal intraocular lenses (IOLs) are three-focus lenses that are put into the patient's eye during cataract surgery.

Patients benefit from trifocal IOL implants since they are more comfortable and eradicate visual difficulties for the rest of their lives. Patients with vision issues and severe farsightedness owing to cataracts, as well as those who wish to avoid wearing glasses for myopia at a young age but are not candidates for laser surgery, should consider trifocal IOLs. Trifocal IOLs, as its name suggests, enable good vision without glasses at three distances: close, medium, and far.

Each person's natural lens is unique. The lens contains an elastic and transparent structure that can lose flexibility and distort with age, resulting in impaired vision and poor focus. The visual flaws are addressed when a natural lens with a deformed structure is replaced with an artificial clever Trifocal IOL, which provides clear vision at near, distant, and medium distances, considerably enhancing comfort and quality of life.

What is presbyopia?

After the age of forty, the lens inside the eye begins to lose its flexibility, thicken, and stiffen, affecting the eyes' ability to focus on objects that are close to them. Presbyopia worsens as people become older.

Many patients dislike wearing glasses because they age them and are inconvenient to use. You can undertake the surgery of transplanting a Trifocal IOLs once and for all to get rid of lenses and spectacles. Patients who have trifocal implants can read, write, perform housework, and even drive a car with ease. As a result, the patient's quality of life improves.

Who is a good candidate for the trifocal IOL?

Eye angles known as kappa and alpha angles should be acceptable for this process, as should the eye's contrast sensitivity.


Who should receive trifocal iol?


— Patients over the age of 40 who have visual impairments at close and intermediate distances


Patients with visual impairment due to previous laser operations that distorted the lens – Patients whose cornea is too thick to be corrected with a laser – Patients whose cornea is too thick to be corrected with a laser – Patients whose cornea is too thick to be corrected with a laser – Patients whose cornea is too thick to be corrected with

Patients suffering from hyperopia or myopia


Are trifocal iols long-lasting?


Smart Trifocal IOL implants are permanently implanted in the eye after a single procedure.

– With the help of ultrasound, a clouded natural lens multiplies and turns into an emulsion, and then is removed from the eye through micro-access in the cornea.

– In the capsule, where the natural lens was previously located, a flexible intraocular lens is introduced through an individual injector, which independently unfolds inside the eyes and is firmly fixed.


The micro-access is self-sealing; suturing after surgery is not required. The operation takes about 15-20 minutes. The patient does not feel any discomfort or pain, as the procedure made under local anesthesia. The same procedure applies to the other eye for several days.



Prior to making a decision on the operation, an analysis of the patient’s general state of health and the results of an examination of his visual system are mandatory.

Among the contraindications to the operation to replace the lens can be identified:

– Age-related macular degeneration

– Diabetic damage to the retina

– Strabismus

– Diseases associated with a violation of the cornea shape

– Decompensated glaucoma. The operation to replace the lens is possible only after normalization of intraocular pressure (excluding the type of glaucoma, when cataract is the cause of increased intraocular pressure)


How long does it take to recover from lens replacement surgery?

On the first night after surgery, you need to sleep with a transparent plastic protector in front of your eyes. The next day, this protector is removed, and after eye control, you can return to everyday life. The first few days there is a temporary blurred vision due to the expansion of the pupil during surgery. Clear vision comes in a few days. Within a month, you need to use eye drops prescribed by your doctor.
