Multifocal intraocular lens surgery

Intelligent lenses are multifocal intraocular lenses that are mainly used in the treatment of cataract patients over 40 years of age and enable patients to see clearly at far, near and intermediate distances. They can also be used in myopia, hyperopia and astigmatism patients whose eye structures are not suitable for laser treatment. After the operation, the patient no longer needs to wear glasses. Smart lenses are also known as Trifocal lenses.

70% of the human eye’s focus is provided by the corneal layer and 30% by the natural lens of the eye. In a healthy eye, the natural lens of the eye bends due to its structure, so that we can focus both in the distance and in the near. With age, especially after the age of 40, many people lose their eye flexibility and have problems with near vision.

In addition to the single vision lenses, which were used in the past as monofocal lenses in cataract operations, which enable far and near vision, intelligent lenses are being added today. With the use of smart lenses in cataract surgery, the use of additional glasses has been eliminated so that patients can see other focal points than a single focal point.

Refractive lens exchange (multifocal intraocular lens) helps provide the patient with clear and high quality vision at all distances by bending according to the patient’s field of view and the point he wants to focus on at that moment.

Why are smartlenses (multifocal intraocular lenses) needed?

Everyone has a natural lens inside the eye, and that lens is both transparent and elastic. Thanks to its flexibility, this lens can focus on the viewed distance by changing its shape with every close and distant view. In this way we can see both in the distance and up close.

With advancing age, the natural lens in the eye initially loses its flexibility. After a while, on closer inspection, it cannot change shape or focus. Over time, it loses transparency even with old age and cataracts occur.

Our own natural intraocular lens, which loses its flexibility around the age of 40, is an interchangeable lens. Instead of our deformed natural lens, an artificial lens called a smart lens is used. This new lens can now focus in the distance as well as in the middle and near. In the future, cataracts will not occur in patients with an intelligent lens (intraocular lens).

How do smart lenses (multifocal intraocular lenses)  work?

Light entering the eye from different distances is refracted by the natural lens of our eye and merges into a single focal point on the retina. This is how we perceive the picture. Our natural lens in our eyes does this by bending towards different focal points. The same principles apply to the multifocal intraocular lens. It enables the light coming from far, near and medium distance to be focused with a single lens. With intelligent lenses, it is possible to set the focal lengths where the person has trouble focusing. In addition, smart lenses can be selected based on the person’s eye type. In other words, smart lenses can be customized to suit the needs of the person. This means that glasses with several different distances can be superfluous.

What are the areas of use?

Smart lenses are used in the treatment of patients with cataract disease caused by the loss of transparency in the natural lens of the eye or in the treatment of patients with age-related myopia. It is a permanent treatment for both cataracts and age-related myopia. These treatments are based on the principle of removing the natural lens from the eye and replacing it with an artificial intraocular lens.

What types of multifocal intraocular lenses are there?

Monofocal lenses are lenses that allow us to see from a single viewing distance.

Bifocal lenses are lenses that help us see near and far.

Multifocal lenses are lenses that enable us to see at close, far and intermediate distances. The type of lenses known as smart lenses are trifocal lenses, also known as multifocal lenses.

Who can be treated with multifocal intraocular lens?

The same method is used in multifocal intraocular lens surgery as in cataract surgery, which is used with the phaco method. After the multifocal intraocular lens is inserted into the eye in place of the natural lens, removing and replacing it is a risky procedure and should only be used when necessary. At this point, various tests performed before surgery, the suitability of the patient for the surgery, and the appropriate treatment for the particular patient are important. The purpose of using smart lenses is to enable the patient to see all distances with optimal quality.

If the patient has a dry eye problem, this problem should be eliminated in the preoperative period. People with macular degeneration are not suitable for this application. People with advanced eye pressure problems and those with diabetic retinopathy due to diabetes are also unsuitable for smart lenses.

The anatomical structure of the patient’s eye is also a decisive factor for suitability for the operation. The patient’s kappa angle, i.e. the distance between the visual axis and the anatomical axis of the eye, should be less than 0.4 mm. This ratio can be determined during the examination with optical biometric devices.

Patients over 40 years of age who have distant or near or both vision problems and who have intermediate distance vision are candidates for treatment. Any eye with a smart lens can see both far and near.

For people under 35-40 years of age, Smart Lens Treatment can be used even if the number of eyes is too high to be corrected with the laser.

People who have previously had laser eye surgery may also prefer trifocal lenses if they have decreased vision due to deformation of the intraocular lenses and have trouble seeing far or near.

If the person has cataracts and wants to see both far and near without glasses, this treatment can also be used.

How is the refractive lens exchange operation performed?

multifocal intraocular lens treatment is the process of putting a multifocal lens on patients over 40 years of age with cataracts or both visual impairments during an operation. Thanks to this procedure, the patient does not need to wear glasses after the operation.

Even if they have not yet had cataract problems, people over 40 who do not want to wear glasses and who have and are not having remote and near vision problems can get rid of vision problems for various distances by inserting a smart lens with early cataract surgery suitable for laser treatment.

The method used in multifocal intraocular lens surgery is the phacoemulsification method. Each eye undergoes an operation on the same day or on different days, which lasts about 10 minutes. First, the eye is numbed with anesthetic eye drops. This way, patients will not feel any pain during the procedure. There is no general anesthesia, sedation, or hospitalization. During the operation, multifocal intraocular lenses are attached to the lens cavity inside the eye. After the operation, the eye is bandaged and the patient can go home with an escort. The patient begins to see on the same day. Treatment is stopped by using the same procedures on the other eye on the same or next day.

Are intraocular lenses permanent?

Yes, intraocular lenses are permanent. Intraocular lenses correct the patient’s eye disorders. After inserting these lenses into the eye, the patient can use these lenses for the rest of their life. In other words, these lenses do not deform depending on the age of the patient. For this reason, it is critical to conduct a thorough examination of the patient prior to treatment and to correctly determine the number of eyes.

Use of multifocal intraocular lenses in cataract surgery

In previous years, unifocal or bifocal intraocular artificial lenses were used in cataract surgery. The use of trifocal intraocular lenses is becoming more common every day. This is because a single lens can provide a clear view at all focal lengths. Smart intraocular lenses offer a permanent solution for cataract treatment.

The use of trifocal lenses in cataract surgery is carried out using the Phaco method. The operation begins by numbing the eye with anesthetic drops.

General anesthesia is only used in special cases. First, the natural lens of the eye, which has lost its transparency, is removed. It is then attached to the intelligent intraocular lens mount. The same procedure is applied to the other eye.

What should be considered after the operation?

The regular use of eye drops that are prescribed is an important issue. Be careful not to lie face down for the first week. Eyes should not come into contact with water for 5 days. Patients can return to their normal working life after 2 days. The next day, the patient is checked for the first time by the doctor.

What are the risks of the surgery?

Full sterilization is provided so that the eye is not infected with germs during the operation. In addition, the success of the operation is directly proportional to the quality of the lenses used and the experience and knowledge of the surgeon. Of course, like any operation, intelligent lens surgery involves various risks. However, under optimal conditions, these risks are minimized and the operation can be completed successfully.

What is the significance of multifocal intraocular lenses?

The most important characteristic of multifocal intraocular lenses is that they enable medium-range vision. Vision is guaranteed even at distances where the quality of vision is most important, such as TV viewing distance or access distance to kitchen counter.

Smart lenses (multifocal intraocular lenses) are used to treat cataracts and eliminate multifocal visual disturbances.

What are the benefits of multifocal intraocular lenses?

It is an operation that helps people with refraction problems like myopia, astigmatism, and hyperopia, as well as people with cataract problems, regain their vision. The advantages of smart lenses are as follows:

  • Patients feel no pain during the operation
  • It is a process that can be completed in an average of 10 minutes
  • Intraocular lenses inserted after surgery can be used for a lifetime
  • There is no progression of the eye disease after the operation
  • Thanks to multifocal intraocular lenses, several focus distances can be seen without glasses
  • By using multifocal intraocular lenses in the treatment of eye diseases such as cataracts, patients will not recreate cataracts
  • It can be used in patients with advanced eye diseases that cannot be corrected by laser treatment for some refractive problems of the eye
  • As a result of the operation, a significant improvement in visual quality is observed
  • After intraocular lens surgery, the patient does not need to be hospitalized

What are the differences to laser treatment?

While laser treatment can be used for refractive problems such as astigmatism, myopia, and hyperopia, the multifocal intraocular lens can be used for both the above refractive problems and cataract treatment. While a minimum age of 18 years is required for laser treatment, a minimum age of 40 years is recommended for multifocal intraocular lens surgery.

Does the multifocal intraocular lens cause allergies? Does it show any side effects?

Structurally, they are made in accordance with our textures. Therefore, they have no side effects and do not cause an allergic reaction.

Can I start seeing right away with the multifocal intraocular lens?

After the operation, the bandaged eye is opened the next day and visual activity begins immediately. The quality of vision improves gradually over a month.
