Trifocal (Three-Focus) Intraocular Lens

Trifocal (three-focus) or so-called “smart” lenses are used to correct near, intermediate, and distance vision. The upper part of the lens supports distance vision, the middle part supports intermediate vision, and the lower part supports near vision.

Optical Features and Design

• Distance vision: Covers distances of 5 meters and beyond. For example, looking at an object at the far end of a room.

• Intermediate vision: Covers a range of 60–80 cm. This is typically used for activities such as viewing a computer screen.

• Near vision: Covers a range of 35–45 cm. This includes activities such as reading a book or doing work at hand.

What Are the Advantages of Trifocal Lenses?

A broad range of vision is one of the key advantages of trifocal lenses. They may provide visual support for near, intermediate, and distance vision, helping to reduce dependence on glasses for many daily activities such as reading, working at a computer, or driving. In addition, the trifocal design can support patients in maintaining a more active and independent lifestyle, which may contribute to a more comfortable visual experience.
Since trifocal lenses are permanently implanted, they do not need to be removed and, in many patients, can provide long-term visual clarity without the need for further cataract surgery.

Who Are Trifocal Lenses Suitable For?

Trifocal intraocular lenses may be a suitable option for patients who want to enhance their quality of life and achieve clearer vision at multiple distances. Their ability to provide vision support at near, intermediate, and far distances can be advantageous for many people with active lifestyles. They may be considered for patients who wish to reduce their dependence on glasses in daily activities such as reading, computer use, driving, and social interactions.
Patients with good visual acuity and no significant additional eye diseases are more likely to benefit. For those requiring removal of a cataract-clouded natural lens or undergoing refractive lens exchange, trifocal lenses can be a long-term option that supports stable vision. As a result, many patients may experience functional and satisfying outcomes.

Trifocal intraocular lenses are among the advanced options in modern ophthalmology and, for some patients, may provide clear vision at near, intermediate, and distance ranges with reduced need for glasses. When considered for cataract surgery or refractive lens exchange, they can support long-term visual clarity. Their ability to promote a more independent, active, and comfortable lifestyle makes them a valuable option for patients seeking reduced reliance on glasses and improved vision at multiple distances.
