Trifocal Lens Replacement

Trifocal Lenses, or Trifocal IOLs, are one of the types of lenses used to treat cataract disease. During cataract surgery, the natural opaque lens inside the eye is removed and replaced with an IOL (artificial) lens. After this procedure, known as laser eye surgery, the patient can completely get rid of glasses.

Trifocal lenses, which are a type of IOL, which means intraocular lens, give the patient three focal distances. These are reading vision or near vision, intermediate vision, and far vision. Depending on the distance the eye focuses, the light is refracted in the lens, providing clear vision at one of the three viewing distances. Thanks to the lens replacement surgery, the focusing power of the eye will increase significantly.

Lens replacement surgery is performed in the same way as modern cataract surgery. In both of these operations, the natural lens in the eye is replaced with an IOL. The trifocal IOL is performed to reduce or completely avoid the need for contact lenses or eyeglasses.

What is the Difference Between Trifocal and Multifocal Lenses?

Cataract patients used to be treated with monofocal lenses. These lenses provided good vision only at distance or only near. Later, monofocal lenses were developed, so patients began to see both far and near clearly. However, monofocal IOLs were also insufficient in situations that required clear mid-range vision, such as working with a PC, doing workouts and driving a car.

Trifocal IOLs have three focal points. Thanks to this lens, patients achieve a combination of extended near, intermediate and far vision. Thus, patients have a much clearer vision and wide viewing angle without the need for anything else such as glasses or contact lenses.

Success Rate in Trifocal Lens Surgery

Patients can become fully accustomed to trifocal lenses in just a few days after surgery. This means gaining clear vision without the need for glasses. After one eye has healed sufficiently in a period of 7 to 10 days, it is recommended that the other eye be operated in the same way. Having surgery on both eyes provides much better vision quality, preventing eye strain and focusing problems.

The proportion of patients who do not have to wear glasses as a result of trifocal lens replacement surgery is over 90%. Since each eye has different anatomy and genetic characteristics, the recovery process after surgery is also different. If the shape of the cornea changes while the eye is healing, the refractive error, also called the eye power, changes. In today's conditions, the best choice among IOLs is the trifocal lens.
