Smart lenses (trifocal lenses) enable clear vision at far, near and intermediate distances and are placed inside the eye as a replacement of the natural lens that has lost its transparency. Smart lens surgery is the process of replacing the natural lens of the eye which has lost its function and causes discomfort to the patient with an artificial lens. Although it is a procedure that is mostly preferred in cataracts, it can also be performed in cases of advanced visual disorders in younger patients.

Types of Intraocular Lenses

  • Monofocal Lens, which has a single focus and is used for single visual distance
  • Bifocal Lens used for near and far vision
  • Trifocal Lens, which means 3-focal, suitable for all distances including intermediate distance.

Types of intraocular lenses can be grouped into three groups. The intraocular lens called Smart Lens is a type of trifocal lens. It is possible to get rid of glasses completely after the procedure because it provides clear vision at every required distance, and it is the most preferred form of treatment.

What is Trifocal Lens?

Trifocal lens is the name given to three focus intraocular lens. It provides clear vision at far, near and intermediate distances. The natural lens of the eye loses its transparency over time. However, it also loses its flexibility resulting in deterioration of vision for far and near distances. With advancing age, cataracts occur because the transparency of the lens is lost. All these eye problems can be eliminated with Trifocal lens surgery, known as smart lens surgery.

Who Can Have Smart Lens Surgery?

Smart lens surgery, which is a frequently preferred method of cataracts treatment, can be performed in the following cases:

  • Astigmatism
  • Far and near vision problems
  • Cataracts

It is generally preferred in older ages. However, those with advanced vision problems and those who are not suitable for laser treatment and such can undergo trifocal lens surgery. The best decision about this topic will be made by your doctor.

How is Smart Lens Surgery Performed?

Before the operation, detailed examination and eye measurements should be taken. The accuracy of these measurements is very important for the successful outcome of the treatment.

Before the procedure, the eye is anesthetized with anesthetic drops. In this way, it is tried to prevent the patient from feeling any pain during the procedure. After the numbing of the eye, the natural lens of the eye is removed. The appropriate trifocal lens is placed in the eye. Finally, the operated eye is covered with a bandage to protect it from external factors.
