What is an intraocular lense (IOL)?
Understand intraocular lenses (IOL's), which are artificial lenses used during cataract surgery.
Summary
There are many forms of IOLs available in Australia that are used in cataract surgery. Here is a list of some of the most common kinds used in Australia, though it will be up to your doctor to recommend the type of IOL best suited to you.
What is an IOL?
An IOL or intraocular lens is an artificial lens implanted into the eye during cataract surgery which replaces the cloudy (cataractous) natural lens being removed.
What are the IOL options?
There are a number of optical designs available and depending on the IOL you choose (in conjunction with your surgeon), cataract surgery may also help you become less dependent on glasses. It’s important to discuss your IOL options with your surgeon prior to surgery to ensure you receive the IOL most suited to your needs.
Here are some common types of IOLs:
These lenses have a fixed focus for one distance, usually distance vision. They can reduce the need for glasses, but most people will still require glasses for close work.
Is laser treatment an option for the removal of cataracts?
Laser treatment for the removal of cataracts is often misunderstood. Laser removal of a cataract is not possible at this point in time, however 'laser-assisted cataract surgery' is available and involves using a femtosecond laser to assist in various steps of the cataract removal procedure.
During traditional cataract surgery, the cloudy lens is broken up using ultrasound energy and then removed manually through a small incision. In laser-assisted cataract surgery, the laser is used to create precise incisions in the cornea, open the capsule that surrounds the natural lens, and soften the cataract for easier removal.
Your doctor will discuss the best technique for you and your particular condition.
Choosing the right IOL for you
Choosing the right IOL depends on various factors, including your lifestyle, visual needs, eye health, and the recommendations of your eye surgeon. Each IOL has its own strengths and weaknesses, and not all designs are suited to everyone.
It’s essential to discuss your options thoroughly with your eye care provider to determine the most suitable lens for you.
