“My father says his eyes have gotten worse, but I don’t know if he needs surgery or just a new glasses prescription” is a message I get from NRI families almost weekly, usually followed by a slightly apologetic “sorry, I know this probably sounds like a silly question.” It isn’t. From abroad, without being able to look at your parent’s eyes yourself, it’s genuinely hard to tell whether “my vision is blurry” means a two-minute glasses update or a surgical conversation.
Here’s a framework to help you figure out which situation you’re actually dealing with before the consultation, so you walk in with better questions.
Start With What Changed and How Fast
The single most useful piece of information for narrowing this down is timeline. A prescription that’s drifted gradually over a year or two, with no other symptoms, points toward a simple glasses update. A gradual haziness developing over months to years, especially with increased glare from headlights or fading colours, points toward cataracts. A sudden change, or vision that’s been stable for years and suddenly shifts, deserves a same-day evaluation rather than either of the above.
When It’s Likely Just a Glasses Update
If your parent already wears glasses and the main complaint is that things look “slightly softer” than before — text harder to read, distance a bit blurrier, but nothing dramatic — this is often simply a prescription that’s drifted, which happens naturally with age even without any underlying eye disease. A basic refraction test, often part of a routine eye check, confirms this quickly.
This is likely the answer if: your parent already wears corrective lenses, the change has been gradual, and there’s no glare, haze, or colour change being described.
When It’s Likely Cataracts
Cataracts develop when the eye’s natural lens clouds over time, and the pattern tends to be fairly recognisable: a gradual haziness described as “looking through a foggy window” or “through smudged glasses that won’t clean,” worse in bright light or when driving toward oncoming headlights at night, and colours appearing duller or slightly yellowed compared to how your parent remembers them. Cataracts are also often first noticed by family, since a person adjusts gradually to their own vision and may not realise how much has changed.
Cataracts don’t always need surgery immediately just because they’re present — early cataracts that aren’t significantly affecting daily activities can reasonably be monitored. Surgery becomes the recommended path once the cataract starts interfering meaningfully with things your parent needs or wants to do, whether that’s driving safely, reading comfortably, or simply feeling confident moving around independently — this is where our cataract & lens surgery team can walk you through what’s actually changed on exam versus what can still be monitored.
This is likely the answer if: the change is gradual, involves glare or haziness rather than sharp softening, and has been building for months rather than weeks.
Where LASIK Fits Into This Picture
LASIK and similar refractive procedures are typically not relevant for age-related vision changes in older parents — they’re designed to correct nearsightedness, farsightedness, and astigmatism in eyes that don’t yet have cataracts, and are usually most appropriate for adults under roughly 40 to 45, before the natural lens has started the age-related changes that eventually lead to cataracts anyway.
If your parent is older and has cataracts, the more relevant procedure is cataract surgery itself, which — depending on the lens chosen — can also correct significant amounts of existing near or farsightedness at the same time, effectively achieving what LASIK does for younger patients, but as part of the cataract procedure rather than a separate one.
LASIK is relevant here mainly if: you, not your parent, are the one considering vision correction and don’t yet have cataracts — this decision guide for a parent’s cataracts and reading glasses doesn’t usually extend to recommending LASIK for someone already needing cataract surgery.
A Quick Way to Narrow It Down Before the Consultation
Ask your parent these questions over a call, and note the pattern:
- Has this happened gradually over months, or did it change quickly?
- Do bright lights or oncoming headlights bother them more than before?
- Do colours look duller, or is everything simply blurrier at the same brightness?
- Does closing one eye at a time change what they notice (cataracts can affect eyes unevenly, which sometimes only becomes obvious this way)?
- Is this affecting things they need to do daily — driving, reading, cooking safely — or is it a mild annoyance so far?
The answers won’t replace an actual exam, but they’ll help you understand what to expect and ask better questions once your parent is in front of a doctor.
“The families who get the most out of a consultation are the ones who’ve already had this conversation with their parent beforehand. It means when we’re going through the exam findings, everyone already has a shared sense of what’s actually changed day to day.” — Dr. Shikha Gupta, Co-Director, iClinix
What Happens at the Actual Consultation
Regardless of which of these three your parent turns out to need, a proper eye exam includes a refraction test to rule in or out a simple prescription change, a lens examination to check for cataracts and how advanced they are, and a broader eye health check to rule out anything else — like early glaucoma or retinal changes — that could be contributing to the symptoms your parent has been describing. This is why a proper in-person exam matters more than guessing from a phone description, however detailed.
Frequently Asked Questions
Can a parent have both a cataract and a simple prescription change happening at once?
Yes, quite commonly. An updated glasses prescription might improve things temporarily even with early cataracts present, which is part of why cataracts sometimes go unaddressed longer than they should.
Is it normal for cataracts to affect one eye before the other?
Yes, cataracts often develop at different rates in each eye, which is why a parent might describe one eye as noticeably worse, or why closing one eye at a time reveals a difference they hadn’t noticed before.
How urgent is cataract surgery once it’s recommended?
It depends on how much it’s affecting daily function rather than a fixed timeline. A cataract significantly affecting safe driving or daily independence is more urgent than one that’s mild and well-tolerated, which can reasonably be scheduled around convenience, including a planned visit home.
Can this whole process — screening, decision, and surgery if needed — happen within one trip home?
Often yes, particularly for cataract surgery, which typically has a much shorter recovery timeline than many people expect. This is worth discussing directly based on your trip length.
Should I be the one making this decision, or should it be entirely up to my parent?
Ultimately it’s your parent’s decision, but sharing this framework with them beforehand — and joining the consultation by phone or video if useful — helps everyone make a more informed choice together.
Book a Consultation to Get a Clear Answer
If you’re not sure which of these applies to your parent, a single proper eye exam will tell you far more than any amount of description over a phone call.
