If you’ve been told you have a cataract, or you think you might, the question on your mind is probably simple: do I need surgery now, or can I wait?
For most people, cataracts don’t come with a deadline. Eye doctors usually look at how much your vision is getting in the way of daily life, not at one number on an eye chart. If cataracts are making it harder to do things you want or need to do, like driving at night or reading, it may be time to talk with an ophthalmologist about surgery. If they aren’t, waiting and watching can be a reasonable choice.
This guide explains how to tell the difference, what two major eye health organizations say about waiting, and how to prepare for the conversation with your doctor.

The short answer: it depends on how your vision affects your life
Surgery is the only way to remove a cataract, but having a cataract doesn’t mean you have to have surgery right away. The American Academy of Ophthalmology (AAO) says that if your symptoms aren’t bothering you, you don’t have to have a cataract removed, and that surgery is worth considering when cataracts keep you from doing things you want or need to do. The National Eye Institute (NEI) says much the same: doctors usually suggest surgery when cataracts start to get in the way of everyday activities such as reading, driving or watching TV.
Cataracts usually develop slowly, so many people adjust a little at a time without noticing how much has changed. That’s why it helps to look at what you’ve changed in your routine, not just at how well you see on a chart.
Signs it may be time to talk with an ophthalmologist
These changes can be signs of cataracts. They can also be caused by other eye conditions or by a glasses prescription that needs updating, so an eye exam is the only way to know what is going on.
- You avoid driving at night, or if you have been experiencing glare and halos around lights
- You need more light than you used to for reading, or print looks blurry even with your glasses.
- Sunlight or bright lamps bother your eyes.
- Colors look faded or yellowed.
- Your glasses prescription keeps changing, but your vision still isn’t clear.
- You notice double vision.
- Hobbies, work tasks or everyday jobs, like cooking or reading labels, have become frustrating.
Try this: think back over the past few months. Is there something you’ve stopped doing, or started avoiding, because of your vision? That’s worth mentioning at your next eye appointment.

Can you wait? What two major eye organizations say
Many people want to know whether waiting can cause harm. Two respected sources put the emphasis in slightly different places:
- NEI says most people don’t need to rush into surgery, and that waiting usually won’t harm your eyes or make surgery harder later.
- AAO‘s clinical guideline for cataract in adults (its Preferred Practice Pattern) notes that delaying surgery until a cataract is advanced may increase surgical risk and slow visual recovery.
Both sources start from the same place: the decision is based on how your vision affects your life. In practice, that means waiting can be a reasonable choice while symptoms are mild, as long as you keep up with regular eye exams. It also means that if your vision is getting in the way of safe, comfortable daily activities, it’s worth having the conversation sooner rather than putting it off. Your ophthalmologist can examine your eyes and help you weigh the options.
NEI recommends a dilated eye exam every 1 to 2 years starting at age 60. If you have been diagnosed with a cataract, your doctor may suggest a different schedule.
Other things that can affect timing
- How fast the cataract changes. Cataracts progress at different rates, and it isn’t possible to predict how quickly yours will change.
- What your work and hobbies require. Someone whose job or hobby depends on sharp vision may decide sooner than someone whose daily needs are less demanding.
Other eye conditions. Cataract surgery removes the cataract, but it doesn’t fix conditions such as macular degeneration, glaucoma or diabetic eye disease. Your doctor can tell you how much improvement to expect. Sometimes a cataract also makes it hard for your doctor to see the back of the eye to monitor or treat these conditions, which can be a reason to consider surgery.
What you can do while you decide
If your cataract is mild, some steps may help for a while:
- Update your glasses. A new prescription can sharpen your vision in the early stages.
- Brighten the lights where you read or work.
- Try anti-glare sunglasses outdoors and magnifying lenses for close tasks.
- Limit driving at night if glare, halos or poor night vision are making it difficult. AAO recommends this once these problems begin.
These steps can make daily life easier, but they don’t remove a cataract. Surgery is the only way to do that, and no medicine, eye drop or supplement has been shown to reverse or stop cataracts.
Cost and coverage: a separate question from timing
Insurance is a different question from timing, but many people want it answered early. Medicare and most private insurance plans generally cover cataract surgery that is medically necessary. For Medicare, coverage depends in part on how much your vision is affected, and AAO notes that having surgery before your vision has declined enough to meet coverage requirements can cost more out of pocket. Premium lenses also cost extra. Learn more about Medicare and cataract surgery and cataract surgery costs, and ask the office how your plan applies.
When it isn’t “wait and see”
Cataracts usually change vision slowly. Sudden changes are different. Call an ophthalmologist right away, or seek urgent care, if you notice sudden vision loss or any other sudden change in your vision, new flashes of light, a sudden shower of floaters, a shadow or curtain across your vision, or eye pain. These are not typical cataract symptoms and need prompt attention.
How to get ready for the conversation
Before your appointment, jot down:
- Which activities have become harder (driving at night, reading, hobbies, work tasks)
- When it’s worst: at night, in bright light or up close
- Any changes over the past few months, including changes in your glasses prescription
- Your medicines, eye drops and supplements
- Your questions
Deciding with Dr. Farhangi at UCF Health
Dr. Monika Farhangi is a board-certified comprehensive ophthalmologist and refractive cataract surgeon at UCF Health in Lake Nona. She is a graduate of the UCF College of Medicine, completed an anterior segment research fellowship at Bascom Palmer Eye Institute, and completed her ophthalmology residency at Howard University Hospital. Her profile lists English, Farsi and Persian. Learn more about Dr. Farhangi.
“The decision to have cataract surgery is one I make together with my patients. I consider not only what I see during the eye examination, but also how their vision affects their daily lives, whether they struggle with reading, have blurry vision that no longer improves with updated glasses, or experience glare and halos that make nighttime driving difficult. I remind patients that cataract surgery is usually not urgent, and if they are still happy with their vision, we can continue to monitor their cataracts. Ultimately, the right time for surgery is when their vision begins to affect their quality of life and they feel ready to take that step.”

Frequently asked questions
There isn’t one number that applies to everyone. Doctors look at how your vision affects your daily activities, what they see in your eye exam and what matters to you. Insurance plans, including Medicare, have their own coverage requirements, which often depend on how much your vision is affected, so ask about coverage early.
Often, yes. NEI says most people don’t need to rush and that waiting usually won’t harm your eyes. AAO’s guideline cautions that waiting until a cataract is advanced may raise surgical risk and slow recovery. Your ophthalmologist can tell you which applies to your eyes. Keep up with regular eye exams while you wait.
Cataracts usually change slowly, but the speed varies from person to person and can’t be predicted. Regular exams let your doctor track changes. If your vision changes suddenly, don’t wait for your next scheduled visit.
That is a decision to make with your doctor. Cataracts can slowly make seeing harder over time, and NEI notes they can lead to vision loss. Some people manage for a long while with updated glasses, better lighting and less night driving. Surgery is the only way to remove a cataract if your symptoms start to limit what you want to do.
No eye drop or supplement has been shown to remove, reverse or stop a cataract. Surgery is the only treatment that removes one. Talk with your doctor before trying products that promise otherwise.
NEI describes cataract surgery as very safe and says about 9 out of 10 people can see better afterward. As with any surgery, there are risks, including infection, bleeding, swelling and retinal detachment. Your surgeon will go over them with you. To see what to expect afterward, read about cataract surgery recovery.
You can have cataracts in one eye or both, and a cataract can’t spread from one eye to the other. If both eyes need surgery, they are usually done at separate visits.
