There are a few things about aging you just can’t control. Take your eyesight for example. You can fight it but after a certain age, the fine prints on paper get harder to read. With aging, cataract confirms. You lose your eye vision in a cataract. What happens is that the eye lens gets covered with a cloudy substance which results in vision loss. To cure it, the doctors perform cataract surgery. IOL (Intraocular lens) is a special type of lens that helps in vision gain when placed on the surface of the eye. The new lens implant takes care of the cloudiness caused by the cataract.
An IOL (Intraocular Lens) is a small, lightweight, clear plastic disk placed within the eye during cataract surgery. It rectifies the focusing power of the eye’s natural lens. The lens plays a crucial role in focusing images on the retina. If the lens loses its vision clarity because it does when a cataract develops, light rays don’t focus clearly and thus the image one sees becomes blurry.
Intraocular lenses have many advantages. Unlike contact lenses, the IOL remains within the eye after surgery. There is no need of removing, cleaning, and reinserting,
It may be placed either before or behind the iris. Behind the iris is the foremost frequent placement site. They go to be hard plastic, soft plastic, or soft silicone. Soft, foldable lenses are often inserted through a touch incision which shortens recovery time follow surgery. The rapid evolution of IOL (Intraocular Lens) designs, materials, and implant techniques have made them secure and practical due to restoring normal vision after cataract surgery.
At St. Thomas’s Hospital London, the first IOL implant surgery, with a lens manufactured using “polymethylmethacrylate” (PMMA), was performed. Sir Harold Ridley performed it in 1949.
Sir Ridley opted for ”Polymethylmethacrylate” (also called “Perspex” or “Plexiglas) because he noticed that it stayed motionless within the eyes of Royal Air Force pilots when it entered accidentally from windshields.
PMMA lenses are seldom used nowadays since the fabric is rigid and can’t be folded. This entails a way bigger incision to put it within the attention. With advances in technology, silicone and acrylic became popular materials to be utilized in intraocular lenses. These are soft and foldable materials. Smaller incision helps in insertion into the attention.
There are mainly two purposes of IOLs in general. They are:
Some of the common forms of IOLs are:
These lenses are placed on top of the iris. It is not the physiological position of the natural lens of the attention, and this sort of lens isn’t the popular IOL after non-complicated cataract surgery. ACIOLs are implanted just in case the posterior capsule of the lens is deficient or damaged.
These lenses are tucked into the place over the residual posterior capsule within the physiological position of the natural lens of the attention and are the favored lenses.
Pseudophakic IOLs are of three broad categories. that may be implanted during cataract surgery:
Monofocal lenses, unlike the natural lens of the attention, can only restore vision for one distance, that’s for distance, or for near. The facility of the Monofocal Intraocular lenses is typically calculated so that the patient doesn’t need glasses for sight.
Below are the various sorts of Monofocal Intraocular lenses:
• Aurium (Monofocal): Medennium (USA) manufactures Aurium mono-focal lenses. These lenses are photochromatic, which suggests they become lightly tinted during daytime or bright light and thus prevent harmful UV. Under normal lighting, these lenses become transparent.
• Aurovue (Monofocal): It’s an Indian Company – Aurolab manufactures Aurovue lenses. These lenses are considered entry-level options for cataract surgery and are recommended for somebody on a coffee budget.
• Akreos AO (Monofocal): Akreos AO are almost like Aurovue lenses. However, these are the lenses that are imported and are manufactured by Bausch & Lomb (USA).
Multifocal IOLs are lenses that supply an appropriate restoration of vision for both near and distance. While choosing an IOL, it’s vital to recollect that multifocal lenses provide you freedom from glasses for both near and distance, and will be customized to your active lifestyle. Following are the sole multifocal lenses:
An eye can have two sorts of power, spherical power which is because of the natural lens within the attention, and cylinder power which is because of the dissymmetry within the curve of the cornea. Monofocal and Multifocal Lenses can only correct the spherical component of the attention. These both don’t bother about and therefore leave the cylinder power. the cylindrical power requires later correction and additional prescription glasses. Toric Lenses can correct both spherical and cylinder components of the attention. Doctors recommend Toric lenses if you’ve got a high pre-existing cylinder or astigmatism in your eye.
There are a few and rare risks involved in IOL implantation surgery. However, these are rare but your eyes may catch an infection, start bleeding, turn red, and get swollen. Some other risks are as follows:
Any surgery needs time to heal. So does IOL implant surgery. The healing time depends on the severity and the complications of each surgery operated on to each person individually. But, usually, it takes around seven to eight weeks to get completely healed. During this period, try and keep your treated eye covered with eyeglasses. It should not be left uncovered even while you are asleep.
Fortunately, unlike your eye lens, the IOLs do not seize up. Therefore, they don’t need to get replaced. To avail the benefits of these long-lasting lenses, patients need to follow some of the aftercare steps to keep the functioning of the IOLs in condition. Here are the steps you need to take care of after your cataract surgery and IOL implantation:
The advantages of IOL implantation vary based on various IOLs. The following are the benefits of different IOLs:
With all the IOLs mentioned above, there comes a common disadvantage. It is:
Following are the difference between LASIK surgery and IOLs
