HOW DO MULTIFOCAL IOL’S WORK?
What are my lens choices?
The artificial replacement lens used to replace your cataracts is called an intraocular lens or IOL for short. These IOLs are very small and are highly advanced medical devices that are designed to mimic your natural crystalline lens.
Different types of implantable lenses are designed to meet individual eye health and lifestyle needs, so be sure to talk to your doctor about which lens is right for you.
Monofocal IOL: This traditional lens will give you good vision for seeing objects in the distance, such as when you’re driving (but only if you do not have significant astigmatism). For near or intermediate vision, such as reading or surfing the Internet, you will need to wear glasses. There are many types of monofocal lenses that you can choose.You can ask your doctor which one is best for you.
Toric IOL: While a standard IOL can improve your vision by replacing your eye’s cloudy natural lens, if you have astigmatism you may still need glasses or contacts to see clearly. However, depending upon your priorities and lifestyle, your doctor may recommend a premium toric IOL, such as the TECNIS® Toric IOL. Its advanced design replaces your cloudy natural lens, corrects your astigmatism, and typically provides crisp, clear vision with less reliance on glasses for distance vision. However, after surgery, you may still need glasses to ensure optimal near vision.
Multifocal IOL: These types of lenses are designed to be able to provide patients the ability to see objects clearly at different distances without glasses—near, far, and intermediate. The lens material distributes light to different distances, which the eye can focus on for sharper vision. For people who are active and find wearing glasses inconvenient, the multifocal lens can be the optimal choice.. Lenses with the most advanced technological innovations are designed to give nearly everyone independence from glasses. For example, the TECNIS® Multifocal lens is intended to give people high-quality vision in a range of light conditions, including low light situations, such as driving at night and reading a menu in a dimly lit restaurant. Some patients may notice rings or halos around light when driving at night right after surgery. But over time, the visual impression of these rings typically lessens or goes away, as your eye and brain adapt to the lens. You can find more information about this lens at www.TECNISMultifocal.com.
Accommodating IOL: This type of lens is designed to shift or move with the muscles of the eye to help patients focus at different distances. These lenses attempt to change focal points by moving back and forth in the eye—closer to the front of the eye for near vision and then toward the back of the eye for distance vision. With an accommodating lens, some people don’t require glasses for up-close vision. This IOL may be a good fit for people who choose to minimize their dependence from glasses but also suffer from macular or other eye disease.
What to expect before your Cataract Surgery!
Routine exam and tests
After your doctor has examined and diagnosed you with cataracts, he or she will conduct a few tests to see if you are a candidate for surgery and decide which replacement lens is right for you.
The tests involve seeing how much your cataract has developed, measuring the curve of the cornea and the size and shape of your eye, and dilating your eyes to look inside at the back part where the retina is located.
After taking the tests and lifestyle questionnaire results into account, your doctor will decide the best IOL for your vision and lifestyle.
Food and medications
Your doctor may ask you to not eat or drink anything 12 hours before your procedure. Also, remember to talk to your doctor about any medications you are taking and if they will affect your surgery.
Day of surgery
Don’t forget to take the prescribed eye drops to prevent inflammation and infection. You should ask someone to drive you to the eye center, as well as back home.
Our office will supply you with a complete set of instructions for you to follow.
What to expect during the procedure?
You will most likely be awake for the procedure. Your doctor will apply anesthetic drops that will completely numb your eye. You may feel slight pressure in your eye, but you shouldn’t feel any pain. Remember, this is a safe, proven procedure. The doctor and surgical staff will carefully monitor you throughout the entire surgery.
Your surgery will last about 10 to 15 minutes. After a short time to make sure there is no discomfort, you will be advised to go home with protective glasses or a shield. In some case, an eye patch may be applied by your doctor. Be sure not to touch or rub your eye. You can now have someone drive you home to recover.
My life after the procedure
The first day
Many patients have excellent vision the first day after surgery. As your eyes and brain adapt, your vision should continue to get better over time.
Your eyes may feel itchy and sensitive to light. All of this is normal, and it should go away after a day or two. Begin to apply the medicated eye drops that will help with the healing process and prevent infection.
If you received a TECNIS® Multifocal lens, you will probably see halos and glare, which is normal. Your eyes will begin to adjust and this sensation should lessen after a while, although it can be permanent in a small fraction of patients.
You will be able to resume your light daily activities, such as reading, watching TV, using the computer, and walking. Remember to wear the protective eyewear outside in the sunlight and while sleeping. After the first day, you will see your doctor for a postop (after surgery) checkup.
You shouldn’t rub or touch your eyes, and driving is not recommended. Don’t do any strenuous activities or lifting because this will affect the pressure in your eye.
Regaining your vision. Resuming your life.
For the first month, you will check back with your doctor periodically so he or she can make sure you are healing properly. Usually after one month, your eye will be completely healed. You will also notice that everything is brighter and colors are richer with your new lens. This is because you have become used to seeing through a cloudy and yellow-brown cataract lens. Give your brain some time to get used to seeing with your new lens.
With your doctor’s approval, you can get back to your normal daily activities, including active ones, such as driving, golfing, jogging, gardening, and traveling. Many patients report feeling satisfied and a sense of well being with their renewed independence. Take for example the ones who chose the
What are my payment options?
There are many ways to pay for cataract or presbyopia surgery. Usually insurance will cover all or most of the costs. For any additional fees, you will be responsible.
Medicare will usually cover traditional or monofocal lenses. If you choose a multifocal or toric lens, you will need to pay for any extra costs.
Health insurance policies will differ in coverage for the different types of lenses. Usually, most of them will cover a traditional or monofocal lens. Because multifocal lenses are technologically advanced and designed to provide sharper vision, and toric lenses are designed to treat astigmatism, these types of IOLs will cost more. You will be responsible for paying for the additional costs.
Healthcare financial plans offer an option to pay over time. Your doctor may offer their own payment plan or private companies such as CareCredit® can give you financing options that make advanced technology lenses affordable.
