Can drops, supplements or a laser dissolve Ah Ma's cataract? What helps and when surgery is due
No eye drop, supplement or home remedy removes a cataract. Here is what the evidence says, what the laser is for, and how a family can tell that surgery is due.
- The American Academy of Ophthalmology states that cataracts can be removed only with surgery. A Cochrane review found no convincing evidence that N-acetylcarnosine drops reverse a cataract or stop it progressing.
- Lanosterol drops made headlines after a 2015 laboratory and animal study, but later tests on human and rat lenses did not find them dissolving a cataract, and there is no published human trial.
- A Cochrane review of nine trials and 117,272 people found no evidence that vitamin C, vitamin E or beta-carotene prevent or slow cataract. Ministry of Health registration of a supplement checks safety, quality and labelling, not whether it treats a disease.
- Laser-assisted cataract surgery is still surgery. In a meta-analysis of 46 trials, vision was no different after the first week, so the laser is a tool, not a cure.
- Surgery is due when what Ah Ma can see no longer lets her do what she needs or wants to, such as reading, night travel or walking safely, not when the cataract is ripe. An eye examination first tells you whether it is a cataract at all.
No. No eye drop, supplement or home remedy removes a cataract. Surgery is the only treatment that does, and it is considered when blurred vision, glare or falls begin to affect daily life, not when the cataract is "ripe". The laser used in some cataract operations is a tool inside the surgery, not a way of avoiding it.
This page is for the son or daughter who has seen the advertisement, the WhatsApp forward or the shelf in the pharmacy, and wants to know whether Ah Ma can skip the operation. It goes through each claim, then through the signs that tell you the operation is due, and what the day and the weeks after look like.
Can an eye drop dissolve a cataract?
Not one that has been shown to work in people. The American Academy of Ophthalmology states that cataracts can be removed only with surgery. The drop most often sold for the purpose, N-acetylcarnosine, was reviewed by Cochrane in 2017. The reviewers found two small studies they could not assess properly, and concluded that there is no convincing evidence it reverses a cataract or stops it progressing.
Then there is lanosterol, which makes a better headline. A 2015 paper in Nature reported that it reduced cataract severity in dissected rabbit lenses and in dogs. That is laboratory and animal work. When other groups tested it on lenses taken from human patients, a 2015 Indian study of 40 cataract nuclei and a 2019 study of human and rat lenses both failed to find it dissolving anything. A 2025 review of drug treatments still says treatment is predominantly surgical and that clinical efficacy has yet to be confirmed. No published human trial of lanosterol drops has been reported.
Research on drops is real and continues, and one day something may work. Today, a drop bought for Ah Ma's cataract is a drop that has not been shown to clear it.
Do supplements, vitamins or herbal products help?
No supplement has been shown to remove a cataract or slow it. A Cochrane review pooled nine trials with 117,272 people aged 35 and over, followed for between two and twelve years, giving vitamin C, vitamin E or beta-carotene. It found no evidence that they prevent cataract or slow its progression, and noted that beta-carotene turned the skin yellowish in 7.4 to 15.8 percent of people.
Registration is not proof of effect, either. In a Utusan Malaysia article on 17 May 2026, Dr S Abirami Shavani describes products sold as capsules, herbal mixtures or eye drops with claims such as removing cataracts without surgery. She points out that supplements registered with the Ministry of Health are assessed for safety, quality and labelling, not for whether they treat a disease.
The real cost of these products is often time. A cataract left to thicken carries more risk in surgery, as I explain below, so every month spent on a bottle is a month the family could have spent on an eye check. A pair of glasses with an updated prescription can help in the mild stage, and the Academy says so, but that is a short-term help and not a treatment.
Is there a laser that treats cataract without an operation?
No. Laser-assisted cataract surgery is still cataract surgery. The laser takes the place of the blade for some steps, such as the incisions, and the surgeon still completes the operation. A 2025 meta-analysis of 46 randomised trials covering 8,871 eyes found slightly better vision at one week with the laser, but no difference after that, no difference in overall complications, and no clear cost-effectiveness advantage. It is a tool, and the choice of tool is for the surgeon and Ah Ma to discuss.
The other laser is used years after an operation. The new lens sits in a thin pocket called the capsule, and the capsule can turn cloudy, which blurs vision again. A quick laser opening, called a capsulotomy, clears it. That is the capsule, not the cataract, and it is why some people say a cataract "came back" when it did not.
How do we know when the surgery is due?
When what Ah Ma can see no longer lets her do what she wants or needs to do. The NHS lists blurred vision, trouble seeing at night, difficulty reading or watching television, and discomfort in bright light and glare, with double vision, halos around lights and faded colours also possible. The Academy says surgery is recommended when a cataract keeps you from the things you want or need to do, and gives driving, reading and seeing at night as examples.
In our homes that may be missing the step on the stairs, not recognising a face across the room, not wanting to cross the road at dusk, or a fall. The NHS says cataracts do not usually need treatment straight away, so there is no need to rush a decision that she is not ready for.
It is not due when the cataract is "ripe". NICE, the English guidance body, says access to surgery should not be restricted by how well someone reads the eye chart, and that a cataract left to become very dense raises the risk of complications in surgery. I have written about this, and about the routes into surgery in Malaysia, in Ah Ma's cataract: government or private.
The first step is an eye examination, because blur is not always cataract. Surgery does not restore sight lost to other conditions such as macular degeneration or glaucoma, which runs in families, and diabetes can affect the retina, as eye checks in a family with diabetes explains. Only an examination tells you which one it is.
What does the operation day and recovery involve?
A short operation and a same-day return home for most people. The NHS says the operation usually takes between 20 and 45 minutes, usually under a local anaesthetic, so she is awake and should not feel pain. She goes home the same day, but should not drive herself. The Academy adds that the eye is numbed with drops or an injection around the eye, and that she rests in a recovery area for about 15 to 30 minutes first.
Vision may be blurry at first and improves over several days. The Academy says full healing can take about four to six weeks, with prescribed drops, no water in the eye and no rubbing or pressing on it. If both eyes need an operation, they are done on separate days, and she may still need glasses for reading or distance. Complications are uncommon but real: the Academy lists infection, bleeding, retinal swelling, retinal detachment, a dislocated lens implant, vision loss, and halos or glare. The first two weeks at home are in after Ah Ma's cataract operation. Droopy lids afterwards are covered by Dr Catherine Chow in droopy eyelid after cataract or other eye surgery.
A sudden shower of floaters, flashes of light, a dark curtain across the vision or sudden blurring needs urgent care, as the NHS notes these can be signs of a detached retina.
Why do so many older Malaysians put it off?
Mostly because they do not feel they need it, and because they are afraid. In the National Eye Survey II, 26.8 percent of older Malaysians had cataract, and the two commonest barriers to surgery were "need not felt" at 43.5 percent and fear of surgery or a poor result at 16.2 percent. In the same survey of 15,000 people aged 50 and over, untreated cataract was the commonest cause of blindness at 58.6 percent, and 86.3 percent of the causes of blindness were judged avoidable.
So the useful family question is not "which product?" but "what is she afraid of?" Ask her. Listen to the answer before you argue with it. Go with her to the eye examination, and let the doctor explain the operation to her and to you.
Can a child have a cataract too?
Yes, and it is the family flip side of this page. Around three in 10,000 children have a cataract, according to AAPOS, and a baby's vision is still being built, so a cataract that blocks the light can leave the eye permanently weak if it is not found early. A white spot in a baby's pupil is a reason to be seen soon, and not every childhood cataract needs an operation. Cataract in children: not only a grandparent's problem goes through it all. If a baby in the family was born with one, tell the children's eye doctor.
- Floaters, flashes of light or a dark curtain across the vision appear suddenly, which can be a sign of a detached retina.
- Vision suddenly blurs, or an eye becomes painful and red after cataract surgery.
- A baby has a white spot in the pupil.
