Intraocular lenses. Multifocal

The gradual aging of the human body is the natural cause of visual impairment. After 40-50 years of age, the lens becomes denser and loses its elasticity. It cannot change its shape to adjust vision for different distances and preserve the clarity of the image. At some point, virtually everyone needs glasses for near vision and reading. The solution provided by modern ophthalmology is the refractive lens exchange, when the natural lens is replaced by the artificial intraocular lens, or IOL.

Some IOL models make is possible to restore vision at any distance. These lenses are called multifocal IOLs. They have special optical properties allowing them to refract incoming light into several focus points, providing a clear image both at near range and at distance. In the majority of cases, after surgery the patient does not need glasses for either distance or reading. For this reason, multifocal IOLs are a positive and very convenient solution for restoring quality of life and vision.

Indications for surgery

Ophthalmic microsurgery is evolving constantly, as is the design of multifocal lenses. Today, multifocal IOLs can solve a wide range of vision problems. This technology is most appropriate for patients who:

  • Are younger.
  • Are very active socially.
  • Have hyperopia or high myopia combined with presbyopia.
  • Have cataract associated with high myopia.

Multifocal IOLs are not recommended in patients with low visual potential as a result of eye co-morbidity such as glaucoma, age-related macular degeneration, macular hole, diabetes, lens subluxation, etc.

You can make an appointment by phone from 8:30 to 19:30 (daily).

The essence of the procedure

Intraocular lens implantation refers to a microsurgical procedure in which the patient’s natural lens is removed and replaced by an artificial lens made of a biocompatible polymer having a unique structure:

  • An optical part, which provides the function of a natural lens.
  • A supporting (or haptic) part that ensures reliable fixation of the new lens inside the eye.

The optical part of a multifocal lens has several zones. Each zone refracts light to one degree or another. Each zone is used to focus light rays at a particular distance. Therefore, people see well both in daylight and in low light, have the ability to drive a car and to read. Special sections of the optical component enable the patient to see well at intermediate distances.

Before the surgical procedure, the patient undergoes special ophthalmic examinations in order to choose the type of IOL and consider the best recovery program. After surgery, sometimes the patient may initially see halos and glares; however, this problem goes away via the natural process called neuroadaptation, the brain’s readjustment to new optical conditions.

Advantages of multifocal intraocular lens implantation:

  1. Fast and easy surgery.
  2. Procedure lasting just 15-20 minutes.
  3. Minimal risk of complications.
  4. Short recovery time.

During preoperative consulting, the surgeon will select the best IOL option by taking into account individual eye characteristics and the patient’s lifestyle.
