Advanced Vision Correction: Understanding Smart Intraocular Lenses

What Are Smart Lenses? (Trifocal Intraocular Lens)

Advancing and evolving technology is also emerging in the field of eye health. With the latest technological advancements, it is becoming possible to resolve vision problems experienced by individuals.

The human eye is a wonderfully created organ. The corneal layer in the eye possesses 70% of the focusing power. The remaining 30% of focusing is performed by the eye lens. This focusing process continues without problems until the ages of 40-45, but after a certain age, the eye may lose its focusing function. Following this loss, near vision problems may develop in individuals.

As time progresses, the eye lens loses its transparency further and cataract formation begins. After cataract formation, the individual can no longer see either near or far objects. One of the treatment methods applied after the development of this disease is the implantation of smart lenses in the person.

During surgery, the damaged natural eye lens is removed and replaced with artificial smart lenses. These lenses come in three types: monofokal, bifokal, and trifocal, selected based on the person's needs and the doctor's judgment.

How Do Smart Lenses Work?

In their natural form, the light beam entering the human eye is refracted and sent to the retina at a single focal point, where it converges. After this process, vision occurs. Our natural eye performs this process by flexing on its own; however, after some time, it becomes unable to perform this function.

The solution to this is the surgical implantation of smart lenses that perform this function into the eye. These lenses work on the same principle. They refract light and send it to the retina at a single focal point. This is the answer to the question "How Do Smart Lenses Work?"

Trifocal lenses are produced with the aim of refracting light coming from distances such as near, far, and intermediate, and working on the natural eye principle. These lenses are also custom-manufactured according to each person's individual needs. This way, patients can achieve vision close to natural by using lenses suitable for their conditions and customized for them.

What Are Their Uses?

To answer the question "What Are Their Uses?", smart lenses produced with the latest technology can generally be applied to individuals with cataracts or those experiencing vision problems due to age. Additionally, smart lenses may be presented as a treatment option for patients whom the doctor finds unsuitable for LASIK laser treatment.

However, doctors may not find these lenses suitable for everyone. Besides vision problems and cataracts, healthy eye structure is an important criterion for this surgery. That is:

• Individuals with glaucoma,
• Individuals with retinal disease,
• Individuals with macular degeneration,
• Individuals with optic nerve disease,
• Individuals experiencing eye problems due to diabetes cannot receive smart lens treatment.

What Are the Types of Multifocal Intraocular Lenses?

We can explain the answer to the question "What Are the Types of Multifocal Intraocular Lenses?" as follows:

Smart lenses that provide vision by focusing on a single viewing distance, either far or near, are called monofokal lenses. After using these lenses, eyeglass correction is needed.

In bifocal lenses, both far and near distances are targeted. These are called bifocal lenses.

Multifocal lenses, also known as trifocal lenses, are referred to as smart lenses. In these lenses, focusing is performed at far, near, and intermediate distances.

Smart Lens Treatment

The procedure of removing the lens that has lost its transparency during cataract surgery and replacing it with smart lenses is called Smart Lens Treatment. After this surgery, performed by specialist doctors in a hospital setting, individuals no longer need the eyeglasses or regular contact lenses they previously used.

How Is Smart Lens Surgery Performed?

This surgery can be performed even without cataract development on individuals over 40-45 years of age who do not wish to wear glasses. For this procedure to be applied, the person must be unsuitable for LASIK laser treatment.

Regarding the answer to the question "How Is Smart Lens Surgery Performed?"; the surgery is performed on both eyes on different days. The average surgery duration is approximately 10 minutes. During this time, the eye is first numbed with anesthetic eye drops. This numbness prevents the individual from experiencing pain or discomfort during surgery. Contrary to common belief, general anesthesia is not applied, and the patient does not need to remain hospitalized after the procedure.

After the surgery, the eye is covered with a bandage and kept that way overnight. The following day, when the bandages are removed, the person begins to see. A few days after the first eye surgery, the procedure is also performed on the other eye, and the treatment process is completed.

Technologies Used in Smart Cataract Surgery

The technological methods used in cataract surgery have improved over time. Cataracts, which cause complaints such as blurred vision, difficulty with night vision, and reduced overall visual quality, are treated in classical methods by manually removing the natural lens and replacing it with an artificial lens. Along with technological advances, some supportive methods available to surgeons include:

• Femtosecond laser: This laser technology can help the surgeon create more precise incisions on the eye and allows computer-assisted imaging to map the eye anatomy during the process of removing the clouded lens. This way, personalized planning for lens placement can be performed.
• Artificial intelligence-assisted evaluation: Preoperatively, patient data such as medical history, imaging scans, and biometric measurements can be analyzed by computer-assisted systems to provide the surgeon with additional information. Such systems can be considered as decision support tools in surgical planning.
• Intraoperative imaging systems: Imaging systems that provide real-time feedback during the surgical process allow the surgeon to make necessary adjustments as needed during the procedure.

The use of these technological tools is evaluated by the doctor according to the patient and eye structure; it does not mean that the same result will be obtained in every patient.

What Precautions Should Be Taken After Surgery?

Smart lens surgeries are a type of surgery that is completed in a short time when performed by expert hands and resolves the person's problems. The issue that people are most curious about, What Precautions Should Be Taken After Surgery?, is quite confusing. We can list this topic for you as follows:

• First of all, the patient should not forget that they recently had surgery and should take good care of their eyes. They should not rub them.
• The medications prescribed by the doctor should be used on time and regularly.
• For the first 7 days after surgery, the patient should not sleep face down.
• For 5 days after surgery, the eye should not come into contact with water.
• 2 days after surgery, the person can return to their daily home and work life.
• The first postoperative checkup should be performed by the doctor the day after surgery.
• Subsequent routine checkups should continue one month after the second visit, then every 6 months.

What Are the Risks of Smart Lens Surgery?

The ease of use of smart lenses that people with vision problems in their eyes will choose is a known fact. However, the question What Are the Risks of Smart Lens Surgery? is one of the questions that comes to people's minds. We can explain these risks for you as follows:

This surgery does not have serious risks. However, the most important factor in its safety is the expertise and experience of the chosen doctor. This experience minimizes the risks that may occur during surgery. Additionally, the smart lens chosen should be of high quality, and the surgical area must be properly sterilized.

Some Conditions That May Be Observed With Trifocal Lenses

Trifocal intraocular lenses are lens options that aim to provide vision at near, intermediate, and far distances and reduce eyeglass dependence after cataract surgery or refractive error correction. However, as with every medical application, there are some conditions that may be reported by some patients with these lenses:

• Visual disturbances: Some patients may report visual effects such as glare, light halos, or starburst patterns. These conditions may be more noticeable, particularly during nighttime driving or in low-light environments.
• Changes in contrast sensitivity: Some individuals may experience changes in contrast perception; this condition can affect the sensation of clarity in certain visual situations.
• Intermediate distance performance: Although the lenses aim to provide vision at three distances, some users may experience different clarity than expected for intermediate distance tasks such as computer screen reading or phone use.
• Complexity of lens selection: Many factors such as corneal astigmatism, pupil size, and the patient's daily visual needs must be properly evaluated. Careful evaluation by the doctor and selection compatible with outcome expectations are important.

Therefore, the choice of trifocal lenses should be evaluated by the doctor after examination, taking into account the patient's eye structure, lifestyle, and visual needs.

What Are the Advantages of Smart Lenses?

To explain What Are the Advantages of Smart Lenses?, we can list them as follows:

• Patients do not feel pain or discomfort with the anesthetic drops applied to the eye during surgery,
• It is a surgery performed in approximately 10 minutes,
• The patient uses these implanted lenses for life,
• After surgery, there is no further progression in the eye's refractive error,
• After smart lens implantation, patients no longer need eyeglasses or contact lens equivalents,
• Cataract does not develop in the eyes after smart lens surgery,
• It can be applied to eyes that are not suitable candidates for LASIK laser treatment,
• Significant improvement in vision is achieved after surgery,
• The patient does not need to remain in the hospital for observation after surgery. They are discharged immediately.
