Multifocal Lens

Multifocal Lens

Multifocal lens is a treatment method applied to treat eye disorders such as cataracts. The most basic principle of this method is to replace the natural lenses in the eye with prosthetic lenses. Prosthetic lenses placed in the eye are produced with very special technologies. The lens in the eye has an extremely clear structure and allows the light to be transmitted to the retina by refracting it, thus allowing the eye to see objects from all distances.

“What is a smart lens?” The question is one of the questions frequently asked. This treatment method, also called multifocal lens, is also known as trifocal in the medical literature. Trifocals are trifocal intraocular lenses that provide the elimination of multifocal problems. Thus, it is also used in the treatment of patients who have eye refraction problems that are not suitable for laser treatment. Thanks to this treatment, patients can perform tasks that require focus, both at close range and at a distance, without having to wear glasses. Especially with the developing technology, this treatment method, which replaces single-focal lenses, provides comprehensive correction of vision disorders and brings the patient's vision to the most natural state possible. These lenses are designed in different ways, such as bifocals or trifocals, and the patient stops using glasses after the treatment.

The most important function of smart lenses is to refract light from all distances and transmit it to a single focal point on the retina. Thus, thanks to a single lens, it is possible to focus on objects at close, middle and far distances. Thanks to this, the person's need for contact lenses or glasses is eliminated.

These lenses are used when the natural lens in the eye loses its clarity or does not function properly for various reasons, and the most common use is cataract.

Multifocal lenses vary in focus types. These are as follows:

  1. Monofocal (single focus)
  2. Multifocal
  3. Trifocal (trifocal)

After the monofocal application, which is also called a single-focus lens, the patient starts to see well in the distance, but uses glasses to see near. In multifocal, which is called a bifocal lens, patients can see both far and near without the need for glasses.

Smart lens surgery is performed with the phacoemulsification method after numbing the eye with drop anesthesia and the procedure takes about 10-15 minutes. In this procedure, which does not require stitches, only one eye can be treated per day and the operation of the other eye is planned a few days later, and the patient is discharged after the procedure. Those who have smart lens surgery can stop using glasses according to their general condition.

There are some details to consider when choosing a multifocal lens. Persons suffering from conditions such as macular degeneration, diabetic macular edema, diabetic retinopathy and glaucoma are not suitable for trifocal or bifocal lenses. Therefore, it is important for people to undergo a detailed examination. Multifocal lens prices should also be taken into account in the selection and a choice should be made in line with the budget.

  • People over the age of 40 who have vision problems at near, far or both
  • Those who want to get rid of the use of glasses
  • Young patients whose glasses number is too high to be corrected by laser
  • Those who have cataracts and those who want to see far and near without glasses after cataract surgery
  • People whose eye number has been corrected by laser before

There are some points to be considered after smart lens surgery. The most important of these points is the regular use of the prescribed eye drops by the patients. In addition, patients should avoid lying face down for the first week. The eyes should not come into contact with water for the first 5 days after the procedure. Finally, the patient should definitely go to his routine controls.

Multifocal lens; It is an operation applied to eliminate eye refraction problems such as hyperopia, astigmatism and myopia, as well as the problem of cataracts. Before this operation, the doctor performs a detailed eye examination and evaluates the suitability of the patient. In this evaluation, the eye problem experienced by the person is considered as a whole, the general health status and age. The advantages of the smart lens applied as a result of this evaluation are as follows:

  • The patient does not feel any pain during the procedure.
  • It generally takes 10 minutes.
  • The inserted intraocular lenses can be used for a lifetime.
  • There is no improvement in the glasses number after the procedure.
  • Multiple focus distances become clear with the attached smart lens.
  • The condition does not recur with its use in cataract treatment.
  • After the procedure, the visual quality of the person increases significantly.

Multifocal lens surgery is a form of treatment developed with today's technology. Smart lens surgery prices differ according to the products quality and origin. In addition, the special needs of the patient determine the price ranges.

Does the surgery cause pain?

Just before the operation, drop anesthesia is applied to the patient's eyes and the eyes are anesthetized so that pain is not felt during the procedure.

How long does the surgery take?

This surgery consists of anesthetizing the eye, removing the lens from the eye, and placing the smart lens and overall it takes 10 minutes. This surgery, which is performed with the phacoemulsification method, is applied in 2 sessions.


Is it necessary to use glasses after the operation?

Since the lens is placed during the surgery, the need for glasses is eliminated.


Can I drive after the operation?

After the procedure, the patient's vision will be slightly blurred, so patients are recommended to drive 3 days after the procedure.
