Intraocular lens (IOL) is a lens implanted in the eye as part of a treatment for cataracts or myopia. The most common type of IOL is the pseudophakic IOL. These are implanted during cataract surgery, after the cloudy eye's natural lens (colloquially called a cataract) has been removed. The pseudophakic IOL provides the same light focusing function as the natural crystalline lens. The second type of IOL, more commonly known as a phakic intraocular lens (PIOL), is a lens which is placed over the existing natural lens and is used in refractive surgery to change the eye's optical power as a treatment for myopia.
A cataract operation involves removing the natural cloudy lens from the eye. Without a lens within it the eye is widely out of focus and remains legally blind. The best remedy for this is to insert an artificial lens into the eye. This is now a standard part of cataract surgery, though it has not always been so.
This artificial lens is called "The Intra Ocular Lens Implant". Surgeons often refer to it as the IOL (Intra Ocular Lens). If a lens implant is not used the eye must be brought into focus with either a spectacle lens or contact lens. Each of these has disadvantages. A spectacle lens will be thick, heavy and restrict the field of vision. A contact lens has to be looked after and taken on and off the eye. An intra ocular lens once inserted can be forgotten about by the patient and restores the eye to the most nearly natural state.
All intra ocular lens implants have two parts. The central part is the focusing or true lens component of the device. This is shaped like a thin round disc and is usually between 5 and 7 mms in diameter. This part of the lens is called the “optic”. From the edge of this optic extend limbs, called “haptics”. These support the lens in position within the eye and ideally keep the optic centred on the line of vision. Most lens designs have two haptics extending from the optic in opposite directions. There are a few lenses on the market with more than two haptics. The lens as a whole may be made from a single piece of plastic. It is then referred to as a one piece lens. Alternatively the optic and the supporting haptics may be manufactured separately and then fused together. If the lens has two supporting haptic limbs bonded to the central optic it is referred to as a three piece lens. Different lens designs may have differently shaped haptics. These may be simple 'C' or 'J' shaped loops or have more complex sinuous forms. In one design, known as the plate haptic lens, the central lens optic is supported by two paddle shaped limbs and the whole lens has a rectangular form.
Intra ocular lenses are made from clinical grade plastics. These materials need to be chemically stable and inert within the eye. They must not cause any irritation or chemically induced damage to the tissues of the eye. In other words they must be safe and reliable. They must last a lifetime. The first plastic used to make an intra ocular lens was perspex (polymethyl methacrylate); also known as PMMA. It is a rigid material and the same substance from which traditional hard contact lenses are made. Many millions of such lenses have been implanted. One company has devised a means of bonding a substance called 'heparin' to the surface of lenses made from this material. This has the effect of making them 'non stick' and ideal for use in eyes with a history of inflammation or in patients with diabetes. In the UK PMMA lens implants are now going out of use and have been replaced by lens types made from more modern plastics. These materials include silicone and a variety of acrylics. These substances are pliable and lenses can be manufactured from them that can be folded.
