How Vision Changes Over Time
Understanding how your eyes change over time can help bring you one step closer to reclaiming younger vision.
In a healthy eye, the crystalline or natural lens is flexible and pliable. Muscles and fibers within the eye relax and contract, reshaping the lens in order to change focus to near, far or in between, and back again. In a healthy eye, light enters through the eye's natural lens and focuses directly onto the retina, yielding a clear image.
Presbyopia is a common age-related condition that is usually first noticed around the ages of 40 and 50. As we age, the once-flexible natural lens becomes firmer and less responsive to the eye's efforts to change focus. This lack of flexibility reduces the eye's ability to switch from seeing objects at a distance to seeing objects up close, resulting in the need for reading glasses or bifocals.
Presbyopia occurs when the eye's lens loses its ability to change focus and direct light precisely onto the retina. This typically results in blurred vision when reading or looking at objects up close.
SIGNS OF PRESBYOPIA
- Loss of ability to read up close
- Difficulty viewing a computer screen
- The need for reading glasses or bifocals
- The need to hold objects farther away to read
What are cataracts?
A cataract is a clouding of the natural lens of your eye that causes your vision to appear hazy. Cataracts happen gradually as your eyes get older, and the natural lens will eventually need to be removed and replaced with an artificial intraocular lens in order for you to see clearly.
What are the symptoms of cataracts?
Symptoms of cataracts include:
- Clouded, blurred, or dim vision
- Reduced quality of night vision
- Light sensitivity
- Difficulty reading
- Fading of colors
- Double vision in a single eye
What is an intraocular lens?
An intraocular lens (IOL) is an artificial lens that is implanted during surgery to replace your cataract lens. You can choose from many different types of IOLs—some are designed to provide only distance vision, while trifocal lenses deliver near, intermediate, and distance vision for clear, complete focus.3 After Dr. Rohr removes your cataract-clouded lens, he will implant the IOL that you chose before your procedure.
What is a trifocal lens?
A trifocal lens is an IOL that is specifically engineered to provide near, intermediate, and distance vision for clear, complete focus. The PanOptix® Lens, the first and only trifocal lens for cataracts in the United States, delivers enhanced quality and a complete range of vision.
Are there other intraocular lens options?
Yes, there are many different types of lenses. Talk to your doctor to find out which might be right for you.
Does the PanOptix® Lens address presbyopia?
Yes, the PanOptix® Lens is designed to mitigate presbyopia, which is a common condition that makes it difficult to see up close. Addressing presbyopia provides an opportunity to reduce or even eliminate your need to wear reading glasses.
Does the PanOptix® Lens correct astigmatism?
Yes, the PanOptix® Lens is available in a toric option to correct astigmatism. Toric lenses sharpen vision and clear the distortion caused by astigmatism. They may even help free you from glasses and contacts for distance vision.
How long does cataract surgery take?
Cataract surgery is an outpatient procedure that is usually completed within 10 to 20 minutes.4 Recovery time is based on the person and the case, but most people rest for a few hours after surgery. Your doctor may recommend that you wear a protective shield over your eye for several days.
Is cataract surgery safe?
Cataract surgery is one of the safest, most common, and most effective procedures performed in the United States.1 Most people experience little to no discomfort during the process and say that cataract surgery is easier than they expected.
What happens before and during cataract surgery?
Before cataract surgery, you'll meet with Dr. Rohr to talk about your lens options and clarify any questions or concerns you may have. Remember to disclose any current prescriptions or medications you're taking. Before the surgeon begins the procedure, they'll dilate your pupils and apply preoperative medication.
During the procedure:
- Anesthetic is applied to your eye.
- The surgeon makes a small incision in your cornea in order to access the cataract.
- The cataract is gently broken up and removed.
- Your chosen IOL is implanted to replace the original lens.
What should I expect after cataract surgery?
While most people notice an improvement right away, you may experience some blurred vision as you heal. You may need to wear a protective eye shield for a brief amount of time to protect your eye. Be sure to plan for a friend or relative to stay with you to make sure you react as expected to the anesthetic and procedure. If you're interested in enhancing your vision at the time of cataract surgery, ask your doctor if the PanOptix® Lens is right for you.
Can I drive after cataract surgery?
It's recommended that you don't drive for up to 24 hours after your cataract surgery, so you'll need to ask a friend or relative to drive you home. They'll need to stay with you to make sure your recovery goes as expected. Consult with your doctor about the length of time you'll need assistance. Usually, you'll have a follow-up appointment with your doctor the day after cataract surgery. Your doctor will then assess your vision and decide whether you're clear to drive.
Can I exercise after cataract surgery?
Generally, you should avoid strenuous activities for a few weeks after cataract surgery. Talk to your doctor if you have questions about certain activities.
How long do cataract replacement lenses last?
IOLs are very durable and usually last a lifetime. The lens you choose will make a big difference in your vision after surgery. By investing in your vision, you're investing in your future.
