Questions to Ask Before Cataract Surgery
Twenty questions to take to the ophthalmologist before cataract surgery, covering what is causing your vision loss, how the lens is chosen, which costs are optional, the risks, and what the first weeks afterward involve.
The questions
Open any question for the note
How much of my vision trouble is the cataract, and how much is something else in my eye?
Why ask it
Cataract often sits alongside macular degeneration, glaucoma, diabetic changes or dry eye, and surgery only removes the cataract part. Ask what the retina and optic nerve look like on examination, because that determines the ceiling on your result and it is much better understood before surgery than afterward.
Do I need this done now, or is it reasonable to wait, and what changes if I wait a year?
Why ask it
The old advice about waiting until a cataract was ripe no longer applies, and the decision now rests on whether your sight is interfering with things you need to do. Ask whether waiting makes the operation harder in your case, which it can if the lens becomes very dense or you have narrow angles.
Which of the things I struggle with day to day would you expect to improve, and which would not?
Why ask it
Bring specifics: reading small print, glare from oncoming headlights, recognizing faces, seeing in dim restaurants, following a golf ball. A surgeon who tells you which of these will probably improve and which will not is giving you a real forecast rather than a general promise about clearer vision.
Which lens implant do you recommend for me, and what will I still need glasses for?
Why ask it
A standard single focus lens gives excellent distance vision and you wear reading glasses, which suits most people well. Ask the surgeon to say plainly what your glasses situation will be afterward with each option, because the disappointment people describe usually comes from expecting to need none at all.
Do I have astigmatism, and if so how would you deal with it?
Why ask it
Astigmatism left uncorrected keeps vision slightly soft at all distances even with a perfect operation. The options are a toric lens, small corneal incisions, or glasses afterward, and each has a different cost. Ask how much you have measured, since a small amount may not be worth treating.
Am I a good candidate for a multifocal or extended range lens, and what are the trade-offs at night?
Why ask it
These lenses reduce reliance on glasses but a proportion of people notice halos and starbursts around lights and slightly lower contrast, which matters if you drive at night. They also suit some eyes poorly, including eyes with macular disease or an irregular cornea. Ask what the surgeon does when a patient cannot adapt.
Should we aim both eyes for distance, or set one eye for closer work?
Why ask it
Deliberately leaving one eye slightly short sighted lets some people read without glasses, and others cannot tolerate the mismatch. If you have worn contact lenses this way before, say so, since a previous trial is the best available evidence about whether it will suit you.
Does my history of laser vision correction or any other eye surgery affect the lens calculation?
Why ask it
Previous laser correction makes the lens power harder to calculate and the result less predictable, so this is worth raising even if it was decades ago. If you can find your pre-laser prescription and operative records, bring them, because they improve the calculation.
Is there an additional charge for the lens or the technology you are recommending, and is it optional?
Why ask it
Standard surgery with a single focus lens is covered by most insurance and by Medicare in the United States, while premium lenses and laser assisted steps are usually paid out of pocket. Ask directly which parts are optional, and ask whether the evidence shows a benefit in a routine case like yours.
What exactly is included in the price you have quoted, and what will I owe?
Why ask it
Ask for the surgeon's fee, the facility fee, anesthesia, the lens, drops and all follow up visits as separate lines, and ask what happens financially if a second procedure is needed. Get it in writing, since paid upgrades in eye surgery are generally not refundable if you are unhappy with the outcome.
Which of my medications and other conditions do you need to know about before operating?
Why ask it
Some matter more than patients expect. Medication taken for an enlarged prostate can make the iris behave unpredictably during surgery, and surgeons plan differently when they know in advance. Bring your full list, including anything you stopped recently, plus any history of eye trauma, uveitis or corneal disease.
What complications happen in this operation, and how often do you see them?
Why ask it
You are asking for the honest range: infection inside the eye, which is rare but serious, a tear in the lens capsule, swelling at the back of the eye, retinal detachment, and needing a further procedure. Ask what they would do in each case and whether they or a colleague manages it.
What will I see and feel during the operation, and what anesthesia will I have?
Why ask it
Most people are awake with numbing drops and mild sedation, aware of bright light and movement but not pain, and it is over in well under an hour. Knowing this in advance removes most of the fear. Ask what they want you to do if you need to cough or move.
Who will be performing the surgery, and how many of these do you do?
Why ask it
Confirm the name of the surgeon rather than the practice, and ask whether a trainee is involved and in what capacity. Ask where it takes place too, since a dedicated eye surgery center and a general hospital theatre are different environments.
What is the eye drop schedule afterward, and what will the drops cost?
Why ask it
Most people go home with antibiotic and anti-inflammatory drops on a tapering schedule over several weeks, which is easy to get wrong. Ask for the schedule written down, ask whether generic versions are acceptable, and say now if arthritis or a tremor makes putting drops in difficult, since alternatives exist.
What am I not allowed to do afterward, and for how long?
Why ask it
Ask specifically about rubbing the eye, bending, lifting, swimming, hair washing, gardening, dusty work and whether you need a shield at night. Instructions vary between surgeons, so follow the ones you are given rather than what a friend was told.
When will I be able to read and drive again, and when will I get a final glasses prescription?
Why ask it
Vision usually improves within days but settles over weeks, and a prescription taken too early will be wrong. Ask when they expect you to meet the legal standard for driving, and hold off buying glasses until they tell you the eye is stable.
After surgery, what symptoms mean I should call you the same day?
Why ask it
You want a short list to keep by the phone: worsening pain, decreasing vision, increasing redness, discharge, or a sudden shower of floaters or a shadow across your vision. Ask who to call at night and at weekends, and write the number down before the day of surgery.
If both eyes need doing, how far apart will they be, and how will I manage in between?
Why ask it
The gap is usually somewhere between a week and a few weeks. The awkward part is the interval, when one eye has been corrected and the other still needs your old prescription, which can leave you off balance. Ask what to do about your existing glasses during that time, since removing one lens is a common solution.
If my vision lands off target, or clouds over again in a few years, what happens then?
Why ask it
Some eyes end up needing glasses for distance despite a good operation, and a film can form behind the implant years later, which is treated in the clinic with a brief laser procedure. Ask what the practice does about a refractive miss, whether they charge for it, and how long the offer lasts.
Preparing for cataract surgery
Practical guidance for the conversation itself
Before the appointment
Write down what your eyes stop you doing
Keep a short list for a week: reading a menu in low light, headlight glare on the drive home, missing a step, struggling with faces at a distance, giving up a hobby. Surgeons choose lenses around how you use your eyes, and a concrete list is far more useful to them than saying your sight has got worse.
Bring a medication list and your eye history
Include prescriptions, over the counter medicines and supplements, and note anything taken for an enlarged prostate, since it affects how the iris behaves during surgery. Add any history of laser vision correction, eye injury, inflammation, glaucoma or retinal treatment, with dates and old records if you have them.
Take someone with you and write the answers down
Lens choices are easy to mix up an hour after the conversation, and eye drops after dilation make note taking hard. A second person and a written note of what was recommended, and why, means you can compare it against a second opinion or read it again at home.
Ask what is optional before you agree to anything
Cataract surgery is one of the few operations sold partly as an upgrade. Standard surgery with a single focus lens produces very good results for most people. If something extra is being recommended, ask what it changes for you specifically, what it costs, and what happens if you decline it.
Thinking about the lens
- Decide what you would rather do without glasses. Nobody gets perfect vision at every distance in every light, so the choice is about which compromise suits your life.
- If you drive at night a great deal, weigh halos and glare seriously before choosing a multifocal lens.
- If you have any macular or corneal disease, ask whether that rules out the lenses being offered. Simpler lenses often perform better in eyes with other problems.
- If you have previously worn contact lenses with one eye set for reading, tell the surgeon, since that experience predicts how you would cope with the same arrangement now.
- Ask what your likely prescription will be afterward, in plain terms: reading glasses only, distance glasses only, or something in between.
- Remember that a single focus lens plus a pair of reading glasses is a normal and good outcome, not a failure to get the best available option.
The first weeks afterward
- Arrange a driver for the day of surgery and for the first follow up visit, and someone at home for the first evening.
- Set an alarm for each drop round, or use a printed chart to tick off doses. Missing anti-inflammatory drops is a common cause of avoidable trouble.
- Expect the eye to feel gritty and look a little red, and expect vision to fluctuate from day to day at first.
- Do not rub the eye, and wear the shield or glasses you were given if instructed, particularly at night.
- Keep the emergency number to hand and call about worsening pain, falling vision, spreading redness or a new shadow rather than waiting for the next appointment.
- Wait until your surgeon says the eye is stable before ordering new glasses, which is usually a few weeks after the second eye.
- Tell your optometrist and any other doctors that you have an implanted lens, and mention it before any future eye examination.
