Multifokale IOL

Cataract surgery is a procedure that corrects the damage inside the eye that blurs and causes vision loss by replacing it with an artificial lens. Multifocal IOL, also known as an intraocular lens, serves this purpose. Various types of IOLs are designed to solve different vision problems.

What is a Multifocal IOL?

A special type of IOL designed to allow patients to see objects at both near and far distances clearly after cataract surgery. Normally, the human eye changes the shape of the lens to be able to focus on near, intermediate, and far distances (this ability is called “accommodation”). However, this ability diminishes with aging and worsens with the formation of cataracts.

What are the advantages?

The term “smart lens” generally refers to advanced intraocular lenses placed inside the eye during cataract surgery or intraocular lens exchange surgery. This term usually includes multifocal, trifocal, or accommodative materials. They have the potential to improve both distant and near visions of patients, hence they are referred to as “smart”.

A multifocal IOL has the ability to have multiple focus distances without the need for changing the shape of the lens. This is made possible with their design which includes multiple focus points. These lenses allow clear vision at near, intermediate, and far distances by directing the light in the field of view to different focus points.

How is it applied?

The process of implanting a multifocal IOL is the same as standard cataract surgery: • First, the eye is numbed with local anesthesia. This is usually accomplished through drops or injection. • The surgeon then uses ultrasound energy through micro-incisions (very small cuts) to break up the natural lens. This process is known as “phacoemulsification”. • The fragmented lens material is carefully removed. • The folded lens is then passed through the incision and positioned correctly. It typically sits in a natural “pocket” inside the eye called the lens capsule. Once the lens is positioned, it stays in place on its own and doesn’t require additional fixation. • The incisions generally heal on their own and don’t require stitches. The aim of such surgery is to minimize the patient’s need for glasses or other corrective aids after surgery. However, it is important to determine the most suitable type, such as a multifocal IOL, for each patient.
How Long Does a Smart Lens Last?
We can say that intraocular lenses are extremely durable compared to their counterparts. In fact, they can usually stay in place for a lifetime once placed. With good surgical technique and postoperative care, they are expected to last for many years. However, sometimes lens changes or corrections may be needed; these situations are usually associated with rare instances such as lens displacement or misplacement, lens opacity, or the development of another condition in the eye. The overall effects on eye health are generally positive. After surgery, many patients experience improved vision and quality of life. However, there are also some risks and side effects. For example, some patients carry the risk of developing cloudiness around or behind the lens. This condition is called “capsular opacification” and is usually corrected with a laser. Other potential side effects include infection, bleeding, increased intraocular pressure, and retinal tear or detachment. In conclusion, it’s important to carefully discuss with your eye doctor which treatment method is most suitable for you and the potential risks and benefits.
