An intraocular lens implant is a synthetic replacement for the natural lens of your eye. It becomes part of the surgical procedure to repair cataracts which is the removal of the aged, cloudy lens with an artificial replacement or implanted lens.
How your Eye Functions
Each eye has a lens – a window constructed from clear protein as well as water that sits behind the pupil. The lens concentrates light onto the retina, which sends the image formed to your brain in the form of nerve signals.
As you age, the healthy proteins changes and parts of your lens turn cloudy. This is known as a cataract. It can make objects look fuzzy or give them a brownish tint.
Cataracts are a leading source of loss of sight, particularly in older people. Yet they can be fixed via surgical procedure – a treatment that’s done more than 2 million times a year in the USA.
An intraocular lens implant (IOL), is made from a clear plastic, as well as it’s about a third the size of a cent. There are numerous different types as follows:
Monofocal IOL: This is the most usual. Unlike your all-natural lens, which can stretch or flex to assist your eye focus, this implant keeps focused at one fixed range. If you focus at a distance, you may be able to see objects that are far, however you may need glasses to read or see close.
Multifocal implant: Like glasses with bifocal or progressive lenses, this lens has zones that help you see objects at various distances. It might take a number of months for your brain to adapt so your vision seems natural. It can sometimes create even more halos or glare around lights than a mono-focal lens.
Accommodating IOLs: This versatile choice of lens acts more like your natural lens, and also focuses at more than one distance. It makes you less likely to require reading glasses.
Toric IOL: You’ll get this implant if you have astigmatism, or a cornea that’s more football-shaped than round or irregular shaped. This can make vision hazy all around, not just close up or far. This lens decreases astigmatism so you won’t need glasses to fix it after your surgical procedure, apart from curing the cataract.
The Surgical procedure
If you have a cataract, you’ll see an eye doctor. This doctor concentrates on eye surgical treatment as well as other eye issues. He’ll possibly tell you it’s ideal to wait to get rid of the cataract up until it begins to impact your day-to-day life. He can do the surgical treatment at a medical facility or an outpatient centre.
To get you prepared, your physician will:
– Measure your eye. This will certainly help him pick the appropriate implant for you.
– Provide you medicated eye drops to take for a few days in advance.
– Ask you to stop taking some medicines or to skip putting on contact lenses for several days ahead of the time of the surgery.
On the day of surgical procedure, he’ll:
– Numb your eye.
– Offer you a drug to help you relax. You may see light during the procedure; however you ought to feel absolutely nothing or only a mild pressure during the surgery.
– Make a tiny puncture in your cornea to get to the lens.
– Break your natural lens into pieces as well as remove it bit by bit.
– Put the implant in position.
– Allow the cut to recover on its own – no stitches.
You can usually go home in less than an hour, but you’ll need someone else to drive, as you won’t be permitted to drive that day.
Is It Risky?
Any type of surgical procedure has a chance of complications. It’s unusual after an intraocular lens implant, but you might see bleeding or get an infection. Redness or swellings are extra common.
More serious risks include: – A detached retina, which happens when the retina which is nothing but a layer of photo-receptor nerve cells separates from the rear of your eye. This is a clinical emergency situation.
– Vision loss.
– Dislocation – when the implant moves out of its natural position or implanted position.
You may also get an after-cataract anywhere from weeks to years after the surgical procedure. This occurs when the cells around your new lens get cloudy as well as your vision obscures. Your physician can fix this with a pain-free laser procedure.
It will take about 8 to 12 weeks to fully recover. During that time:
– Keep your eye shielded with sunglasses as long as possible, and also sleep with your eye shield in the evening.
– Do not rub or press your eye, even if it’s scratchy or exudes a little bit of fluid.
– Take the medicated eye drops your doctor prescribes to help your eye heal up. You’ll use them for several weeks to assist your eye heal.
– Avoid most exercise or heavy lifting. The doctor will tell you when you can do those things again.
