Smart Lenses: A Glasses-Free and Clear View of Life at All Distances!

While wearing glasses or contact lenses is an indispensable part of daily life for many, this dependence can sometimes restrict freedom and affect quality of life. Conditions such as cataracts that develop with age, or presbyopia (age-related near vision impairment) where both far and near vision problems coexist, require different solutions for clear vision. At this point, revolutionary developments in intraocular lens (IOL) technology, especially trifocal or multifocal lenses known as “Smart Lenses,” offer a glasses-free and uninterrupted perspective on life at all distances. These advanced technology lenses are used not only during cataract surgery but also in refractive lens exchange (clear lens surgery) operations to correct refractive errors in suitable candidates, aiming to eliminate the need for glasses and lenses. Estebox Istanbul, with Turkey’s innovative spirit and expertise in eye surgery, offers you personalized consultation to rediscover the world in all its clarity and vibrancy through smart lens technology.

What is an Intraocular Lens? What Does the “Smart Lens” Concept Mean?

An intraocular lens (IOL) is an artificial lens implanted inside the eye to replace the natural eye lens removed during cataract surgery or, for refractive purposes, to replace the clear natural lens. These lenses are specially selected according to the individual’s eye structure and vision needs.

The term “Smart Lens” is a popular definition generally used to refer to multifocal (multi-focus) or trifocal (triple-focus) intraocular lenses. The reason these lenses are described as “smart” is that they are designed to provide clear vision at different distances (far, intermediate, and near).

• Monofocal IOLs: Provide clear vision at only one distance (usually far). Glasses may be needed for other distances.
• Multifocal IOLs: Generally aim to provide clear vision at far and near distances.
• Trifocal IOLs: Aim to provide clear, uninterrupted vision at far, intermediate (computer, tablet, car dashboard), and near (reading, phone) distances. This is the lens type most often referred to as a “smart lens” today.
• EDOF (Extended Depth of Focus) IOLs: Aim to provide a continuous field of vision at far and intermediate distances while also improving near vision somewhat. Night light problems (glare, halos) may be less common compared to multifocal lenses.
• Toric IOLs: Specially designed for patients with astigmatism. Toric versions of the above lens types (monofocal, multifocal, trifocal, EDOF) that also correct astigmatism are available.

For Whom Can Smart Lenses Be the Key to a Glasses-Free Life?

Smart lenses (trifocal/multifocal) can be an excellent option for individuals who want to get rid of glasses and lens dependency, especially in the following situations:

• Those with Cataracts Who Do Not Want to Wear Glasses: By choosing a smart lens during cataract surgery, both the cataract problem is solved, and far, intermediate, and near vision defects are corrected, eliminating or minimizing the need for glasses.
• Those Experiencing Presbyopia (Age-Related Near Vision Impairment): In suitable candidates with presbyopia, which usually occurs after 40-45 years of age and causes the need for reading glasses, the natural lens can be removed and replaced with a smart lens through clear lens surgery (refractive lens exchange) to correct both near and far vision.
• Those with High Myopia or Hyperopia Who Are Not Suitable for Laser Treatment: In some patients with high refractive errors whose corneal structure or prescription is not suitable for laser eye treatment, smart lens application via refractive lens exchange can be an alternative.
• Those with an Active Lifestyle Who Want to Get Rid of Glasses: People who play sports, travel frequently, or need clear vision without glasses for their profession.
• Those Whose Eye Structure and General Health Condition Are Suitable for Smart Lens Application: Individuals whose suitability is confirmed by an ophthalmologist after a detailed eye examination and various tests (corneal topography, optical biometry, retinal evaluation, etc.).

Smart lenses may not be suitable for every individual. Especially in people with certain retinal diseases, glaucoma, or corneal irregularities, or in individuals who need very precise night vision for their profession (e.g., professional night drivers), different lens options or alternative treatments may be more appropriate.

Smart Lens Application: Cataract Surgery or Refractive Lens Exchange

Smart lenses are primarily implanted into the eye during two different surgical procedures:

1. During Cataract Surgery: This is the most common application. The natural eye lens, clouded due to cataract, is removed using the PHACO technique, and a smart lens (trifocal, multifocal, toric, etc.) selected according to the patient’s needs is implanted in its place.
2. Refractive Lens Exchange (RLE) / Clear Lens Extraction (CLE): In suitable candidates who do not have cataracts but have high refractive errors (myopia, hyperopia, astigmatism) and/or presbyopia, are not suitable for laser treatment, or do not want to use glasses/lenses, the natural clear lens is removed and replaced with a smart lens. The procedure is almost identical to cataract surgery.

Both operations are usually performed with topical anesthesia (eye drops), are short, and sutureless.

After Smart Lens Surgery: A New Visual Experience and Adaptation

The recovery process after smart lens surgery is generally fast, but it may take some time for the brain to adapt to the new visual system:

• Immediately After and First Few Days: Vision usually begins to improve immediately after the operation. Mild stinging, watering, or blurriness is normal for the first few days. It is important to use the drops prescribed by your doctor regularly.
• Adaptation to Different Distances: Since smart lenses have different focal points, it may take several weeks to a few months for your brain to get used to this new situation and automatically adjust clarity between different distances (neuroadaptation process). During this process, some patients may experience slight glare, halos, or light sensitivity at night; these symptoms usually decrease or disappear over time.
• The Joy of a Glasses-Free Life: After a successful adaptation process, most patients achieve clear vision at far, intermediate, and near distances without glasses and experience a significant increase in their quality of life.
• Regular Check-ups: Attending follow-up appointments determined by your doctor after surgery is important for evaluating your healing and lens performance.

Most Frequently Asked Questions About Smart Lenses

Q: Are smart lenses suitable for everyone?

A: No, smart lenses may not be suitable for every eye and every lifestyle. Many factors such as eye structure, the presence of other accompanying eye diseases (e.g., advanced glaucoma, retinal diseases), professional requirements, and the patient’s expectations are important in lens selection. A detailed eye examination and doctor’s evaluation are essential.

Q: Will I not use glasses at all after getting smart lenses?

A: The main purpose of smart lenses (especially trifocal lenses) is to enable patients to have clear vision at far, intermediate, and near distances without glasses. Most patients do not need glasses in their daily lives after surgery. However, in some special situations requiring very fine detail (reading very small print for a long time, working in dim light), a low-power auxiliary eyeglass may rarely be needed.

Q: Do smart lenses have disadvantages compared to monofocal lenses?

A: Since smart lenses create different focal points, they may cause visual phenomena such as glare, halos, or light scattering at night, especially in the early post-operative period in some patients. These conditions usually decrease over time or become unnoticeable as the brain adapts (neuroadaptation). Also, a slight decrease in contrast sensitivity may be observed. Such visual side effects are generally less common with monofocal lenses.

Q: What is the lifespan of smart lenses? Do they need to be replaced?

A: Intraocular smart lenses are made of biocompatible materials and are designed to remain in the eye for a lifetime. They generally do not need to be replaced.

Q: Can I get smart lenses even if I don’t have cataracts?

A: Yes, in suitable candidates who do not have cataracts but have high refractive errors (myopia, hyperopia, astigmatism) and/or presbyopia (age-related near vision impairment), are not suitable for laser treatment, or do not want to use glasses/lenses, the natural lens can be removed and replaced with a smart lens in an operation called “Refractive Lens Exchange” (clear lens surgery).
