Are smart lenses smart? (Intraocular lens)

Cataract is the loss of transparency of natural lens in the eye. Our natural lens helps outer lights focus to the behind the eye in other words, vision point. Blurred lens, becoming misty, loss of transparency in other words, emergence of cataract causes problems for the images to reach to vision point. Accordingly it will result in misty images, pale colors, and increase of reflections of headlights at nights.

The single treatment of cataract is the SURGICAL Method. It is surgery in other words the operation. Although the name of operation seems scary, cataract operations are performed easily and in a comfortable way today. Cataract operations are performed by drop anesthesia and completed within 7-8 minutes.

The main procedure in the cataract operations is the removal of intraocular lens becoming blurred and replacing it with transparent intraocular lens. There are two types of lenses used in the cataract surgeries today:

1. Single-focus lenses

2. Multi-focal lenses (Trifocal, Three-focal, smart lens)

Single-focus lens is adjusted to either short or long sight (single focus). Eyeglasses are used for other sights. When multi-focal lenses (Smart Lens) are used, short, long and mid distance vision increases and eyeglasses dependency reduces.

Why is the Smart Lens preferred?

Every healthy individual has transparent and flexible natural eye lens. The natural lens changes shape to the extent of its flexibility when we look at short or long sights and allow focusing. Accordingly, net vision can be achieved for long and short sights.

As the people get older, natural lens in the eye loses its flexibility. Since it cannot change the shape for the short sight, problems of focusing on the short sight will occur. As the people get older, cataract will occur in the lens losing its transparency.

The natural lens starting to lose its flexibility generally after 40 years old can be replaced with an artificial lens. Old lens beginning to be deformed and not doing its duty as the age increases is replaced with artificial lenses called Smart Lens.

By means of this new artificial lens, the eye can focus on long, intermediate and short sight and a clear vision is achieved for all distances. Diopter value of the patients having Smart Lens (Intraocular lens) does not increase. Cataract does not occur in the eye again by means of a successful cataract surgery.

Who can use Smart Lenses?

People above the age of 40 and having long or short sight problems or both of them and desiring to get rid of the eyeglasses are eligible for this procedure. Every patient to whom multi-focal lens has been applied can have clear vision for long and short sight.

“Smart Lens” treatment can be administered to the younger patients whose refractive error (diopter value) is too high to be corrected by the laser procedure.

Smart lens is the first option for the cataract patients desiring to see the long and short sight without any glasses following the cataract operation.

Smart lens method can be applied to the patients diopter value of who has been corrected by the laser operation and who have problems with long or short sight depending on the subsequent cataract.

How is the Smart Lens operation performed?

The procedure applied on different days by holding for a few days or 1 week based on the conditions of the patient for the application to both eyes lasts for about 10 minutes for each eye. Since it is aplied under anesthesia with the eye drop, general anesthesia (except special conditions) and hospitalization is not necessary.

Natural lens in the eye is removed and it is replaced with the Smart Lens. Bandage applied following the operation is opened by the physician on the next day during the control. The patient starts to see on the same day and continues his daily life without eyeglasses.

The same procedure is applied to the other eye and the patient will have weekly and monthly physician controls as well as use of drop for the given period.

Who is not eligible for Smart lens?

Patients to who these lenses will be applied should be evaluated well in all senses. Diabetes mellitus, yellow spot patients, glaucoma patients are not eligible for this treatment method. For this reason, patients to who smart lens will be applied should be examined well, tests and measurements should be performed and the decision of operation should be made accordingly. Smart lens acts smartly in patients meeting all requirements and acts dumbly in patients not being eligible.
