Intraocular lenses work much in the same way as a natural lens would. As light rays enter the eye the IOL bends (or refracts) the light rays to help you see with accuracy. A lens implant may have various focusing powers, just like prescription contact lenses or eyeglasses.
How does an intraocular lens stay in place?
IOLs usually consist of a small plastic lens with plastic side struts, called haptics, to hold the lens in place in the capsular bag inside the eye.
How long do eye lens implants last?
IOLs have been around since the late 1940s and were the first devices to be implanted in the body. Unlike natural lenses, IOLs do not break down over a person’s lifetime and do not need to be replaced.
Are intraocular lens permanent?
Intraocular lenses (IOLs) are permanent, artificial lenses that can replace the eye’s natural lens to restore both near and distant vision. The most common use for IOLs is in cataract surgery, to replace the diseased lens.
What is the newest lens for cataract surgery?

Can your eye lens fall out?
If you’ve had an eye lens replacement for cataract surgery or refractive lens exchange, your intraocular lens implant (IOL) is held in place by a small sac and these thin fibers. Your lens can become dislocated if some or all of the sac or the delicate fibers break.
Can you see without a lens in your eye?
No, the eye cannot focus properly without a lens. Thick eyeglasses, a contact lens or an intraocular lens must be substituted to restore the eye’s focusing power.
Can you go blind from lens replacement?
You may lose vision. Some patients lose vision as a result of phakic lens implant surgery that cannot be corrected with glasses, contact lenses, or another surgery. The amount of vision loss may be severe.
Can you get laser after lens replacement?
The answer is quite simply: yes, you can. While LASIK treats the cornea, cataract surgery treats and replaces the lens within the eye.
Can you have LASIK after lens replacement?
As a general rule, it is best to wait a minimum of 3 months prior to undergoing a laser enhancement procedure. At OCL, our surgeons have specialist training in refractive surgery and as such have expertise in both lens exchange surgery as well as laser vision correction.
Can vision deteriorate after cataract surgery?
No, your vision generally doesn’t deteriorate after cataract surgery unless other problems arise, such as macular degeneration or glaucoma. In cataract surgery, the eye doctor (ophthalmologist) removes the clouded lens from your eye and replaces it with a clear, artificial lens.
Does cataract surgery give you 20 20 vision?
It is a relatively quick procedure with a fast recovery time that restores a person’s quality of life. Some patients ask if they will have 20/20 vision after the procedure. Most patients can achieve 20/20 vision as long as they have no other conditions.
How much do intraocular lenses cost?
Intraocular lens prices are determined by several factors, including the surgeon you choose and the area of the country where your intraocular lens surgery is performed. In general the cost of a lens implant is $1,500 to $3,000 per eye.

What is intraocular lens dislocation? Intraocular lens (IOL) dislocation is a very rare condition that affects patients who have undergone cataract surgery and consists of the displacement of the implanted lens towards the vitreous cavity of the eye.
What can go wrong with lens replacement?
Infection: lens replacement problems can include infection in a fraction of cases – less than 0.05%. Retinal detachment: the membrane at the back of the eye may detach following the procedure. This can be corrected by surgery but quality of vision may not be the same as before.
Why is my contact lens moving?
Does your contact lens feel like it’s moving around in your eye? It may mean your lens does not fit your eye properly. If your lens is too loose on your eye, or if the diameter or base curve is not accurate, it can cause an increased awareness of your lenses, especially when you blink.
