Intraocular Lens Treatments (Trifocal Lens): FAQ

Intraocular lenses are specially designed lenses used in intraocular lens treatment, especially to help correct visual defects. Multifocal lenses, unlike conventional lenses, can have multiple focal points, allowing patients to see clearly at near, medium and far distances without glasses. These lenses are especially used in the treatment of cataracts and visual impairments.

Intraocular lens treatment is especially suitable for patients who have refractive errors such as cataract, myopia, hyperopia, astigmatism and who want to see without glasses. However, it may not be suitable for patients with other eye diseases.

Intraocular lenses enable glasses-free vision at far, medium and near distances, thus eliminating the use of glasses or contact lenses.

Intraocular lens surgery is performed under anaesthetic eye drops. The old lens is removed and replaced with a specially designed lens. The operation is usually short and patients have a quick recovery period.

After intraocular lens surgery, patients can usually return to daily life within a few days, and full recovery takes 3-4 weeks, although this varies from person to person.

Intraocular lenses are designed to remain in the eye for a lifetime and generally do not require any maintenance.

No, intraocular lenses are not noticeable on the eye from the outside.

Trifocal Lenses: Lenses with three focal points provide clear vision at near, medium and far distance. Multifocal Lenses: Lenses with more than one focal point. Monofocal Lenses: Lenses with a single focal point, usually used for long distance.

No, you will not feel any pain as your eye will be anaesthetised with topical drops.

Yes, you can have intraocular lenses without cataracts.

In patients with raised eye pressure, macular degeneration, retinal problems due to diabetes, keratoconus or lazy eye, multifocal (trifocal) intraocular lenses call for particular care; your doctor will assess at the examination whether they are suitable for you.

An add-on lens is a second lens placed in front of the existing one in people who have already had cataract or lens surgery and have an intraocular lens in the eye. It is used to correct a remaining prescription or to support near vision.

No. The lens already in the eye stays where it is; the add-on lens is placed in front of it, in the space between the iris and the existing lens. The procedure is therefore less invasive than removing the existing lens.

The operation is carried out under anaesthetic eye drops and takes about 15-20 minutes per eye. You go home the same day and the first check-up is the next day.

EDOF intraocular lens treatment is a modern technique used to treat eye conditions such as presbyopia (age-related visual impairment) and cataracts. These lenses provide clear vision at far and intermediate distances and reduce the need for glasses; reading glasses may still be needed for small print.

EDOF intraocular lenses provide clear vision from far to intermediate distance and reduce the need for glasses. In addition, there is rapid recovery after surgery and most patients can return to their daily activities quickly.

EDOF intraocular lenses usually provide clear vision at far and intermediate distances. The quality of vision improves rapidly after the surgical procedure and patients can see comfortably at distance and intermediate range without glasses.

After the surgery, the medications and drops prescribed by your doctor should be used regularly and follow-up appointments should not be missed. In addition, rubbing the eyes and excessive fatigue should be avoided.

Most patients return to daily life within a few days of the procedure, and full recovery takes 3-4 weeks.

No. The procedure is carried out under anaesthetic eye drops and you do not feel pain during it. In the first hours afterwards there may be mild stinging or blurring, which usually settles within a few days.

Yes. The ICL is placed in front of the eye's natural lens without removing any corneal tissue. If your eyes change in the future, the lens can be taken out or replaced.

Most patients return to desk work and daily life within a few days. For strenuous exercise, swimming pools and the sea you should wait for the period your surgeon gives you; the first check-up is the next day.

ICL is generally offered to people aged 18 to 45 whose prescription has not changed for at least a year. After 45, as near vision declines, a lens exchange is often the better option.

Multifocal lenses provide clear vision at near, medium and far distances, while monofocal lenses provide clear vision at only a single distance (usually far).

An ICL is one type of phakic lens. Phakic lens is the general name for lenses implanted while the eye's natural lens is left in place; an ICL is a phakic lens made of a flexible material that sits just in front of the natural lens. The measurements taken at the examination decide which type is suitable.

A phakic lens is generally not recommended where the front chamber of the eye is shallow, the cell count of the inner corneal layer is low, or there is uncontrolled eye pressure, cataract or active inflammation in the eye. Suitability is decided by detailed measurements.

Phakic lenses are designed to stay in the eye for many years. If a cataract develops later, the phakic lens is removed and a new lens is placed during the cataract operation. Regular check-ups are therefore important.

Thanks to the latest advances in technology and surgical techniques, trifocal (multifocal) lenses can be worn by refractive lens exchange for patients who do not have cataracts but want to get rid of glasses. However, trifocal lenses are not suitable for every patient who wants to get rid of glasses. The patient's age and eye structure should be evaluated in detail.

Trifocal lenses are special lenses used in intraocular lens surgeries and aim to correct vision at far, medium and near distances. There is no specific upper age limit. It is generally recommended for individuals over the age of 40, because at this age, near vision disorders (presbyopia) begin as a result of the loss of elasticity of the natural lens in the eye. Cataract: During cataract surgery, the natural lens is removed and replaced with a trifocal lens. In this way, both cataract is treated and a clear vision is provided at all distances. Presbyopia: Trifocal lenses are ideal for correcting this condition, which starts after the age of 40 and causes near vision problems. Far and Near Vision Impairment: Trifocal lenses can also be used in eye defects such as myopia (nearsightedness) and hyperopia (farsightedness). Glasses and Contact Lens Addiction: For individuals who do not want to wear glasses or contact lenses in daily life, trifocal lenses can largely eliminate the need for glasses.

Premium trifocal lenses are applied to patients with a high prescription and patients with cataract problems. These people can use multifocal lenses when they want to lead a life independent of glasses. It can be said that the satisfaction rate with multifocal lenses is high, especially for patients with hyperopia. The surgery of these lenses is not performed for everyone. For this reason, details such as the patient's profession, age, prescription and expectations from the surgery are taken into consideration when deciding on the operation. These lenses are made of acrylic. They are designed in such a way that people can use them throughout their lives. In this way, they have a structure that does not deteriorate in the eye for a lifetime. However, it is important that the doctor who will perform the application has high experience.

Multifocal lenses are lenses that give very good results for distance, near and intermediate vision and have very high patient satisfaction. However, multifocal lenses may not be suitable for every eye. For this reason, which lens is suitable for which patient and the patient's visual simulation are evaluated with I-TRACE technology in the preoperative doctor controls.

Diabetes on its own does not rule out an intraocular lens. If diabetes has affected the retina (diabetic retinopathy), a trifocal lens may not be suitable, so the retina is examined in detail before the lens is chosen.

Our hospital has FDA-approved multifocal lenses from globally recognised brands such as Alcon, Zeiss and Johnson & Johnson. Your doctor will help you choose the most suitable lens for your eyes.

The choice of intraocular lens to be used in cataract surgery is of vital importance as it is not recommended to be replaced unless there is a medical necessity. Since multifocal lens application is not suitable for every patient, the correct lens selection should be made carefully. Before the surgery, the general condition and eye structure of the patient should be evaluated in detail. When fitted to appropriate patients by experienced surgeons, the success rate and patient satisfaction after multifocal lens surgery are quite high.

Trifocal lenses may not be suitable for people with serious eye diseases that affect the quality of vision, such as retinal problems or corneal irregularities. Compatibility with the eye structure should be evaluated by the doctor with a detailed examination.

The most preferred lens brands worldwide are brands such as Alcon, Zeiss and Johnson & Johnson.

Toric multifocal lenses are also used to correct visual impairments in people with astigmatism.
