Will my cataracts last a lifetime? DR MARTIN SCURR answers your health questions


I am 62 years old and have had cataract surgery in both eyes. Will this last me for the rest of my life, or will the plastic lenses ‘wear out’?

Steve Lane, by email.

Cataracts are where the lens in the eye becomes cloudy, usually due to age – surgery involves replacing the natural lens with a plastic version and it is so successful and common that few of them we will reach old age without surgery.

This revolutionary vision-restoring treatment is the result of a discovery made by a British eye surgeon, Sir Harold Ridley.

He noted that World War II pilots with eye injuries from acrylic windshield shards (broken by enemy gunfire) did not experience the kind of damaging inflammatory response caused by shrapnel from rocks and needles. fired type.

This led to the development of lenses that could be used inside the eye (intraocular) – the material used was initially the same as for airplane windshields.

Since the mid-1980s, lenses have been made of flexible materials, which means they can be rolled up and inserted through a small puncture, instead of having to make an incision.

The surgery has now been performed for more than 70 years and it is clear that the implanted lens does not deteriorate and lasts for the life of the recipient.

However, in some patients, the original vitreous ‘capsule’ – the membrane that surrounds the natural and retained lens – then becomes cloudy.

In this case, vision was impaired but restored again, using laser therapy as an outpatient procedure, which was both painless and quick.

I recently had my first cold in about two years and it left me with no sense of smell and taste, and deafness in one ear.

I have had both Covid-19 vaccines and recently did a Covid test which came back negative. Is it possible for vaccines to change the symptoms of other common viruses? I’m 70.

David Nobbs, Norwich.

Despite your recent negative test results, my guess is that your ‘cold’ could in fact be Covid-19.

While you didn’t mention the exact duration of your test-related illness, we now know that the Omicron variant can cause cold-like symptoms, instead of coughs, headaches, and symptoms. fever that we tend to associate with earlier variations.

The vaccines you’ve had may explain why you have only mild, cold-like symptoms – that is, a relatively mild attack.

This makes me wonder if the loss of your taste and smell is a sign of lingering Covid – with inflammation possibly causing problems with the nerve cells that play the role. role in taste, smell, and hearing.

Even asymptomatic Covid-19 can lead to prolonged Covid, although the problems you are experiencing will resolve on their own over the next few weeks or months.

However, I would also recommend having your ears checked by a GP – rather than nerve damage following a virus, deafness in one ear can be caused by fluid in the middle ear, which is common after a respiratory infection. .

Your GP can refer you for an audiometry, tests to check your hearing, which can tell if your hearing loss is caused by fluid buildup or your nerve-related hearing loss is caused by an inflammatory response to your hearing loss. virus.

If the problem is really fluid in the middle ear, the preferred option is often to watch and wait, letting this resolve spontaneously (which it mostly happens).

Nasal drops can help clear your nose. But a small number of patients may need a minor surgery, where the eardrum is punctured and fluid is ‘aspirated out’ – and a drainage tube (‘grommet’) is inserted.

Which option is appropriate depends on the severity of the problem and the patient.

My Opinion: Test Drivers for Marijuana Use

After alcohol, marijuana is the most commonly used recreational drug.

Its legal status is changing worldwide, with more and more countries legalizing it, although possession and use remains illegal in the UK.

The near-universal softening of policy has occurred despite the perception that marijuana impairs reasoning and judgment, as well as affects the way the body moves and, therefore, handles a car. .

There is now evidence that marijuana increases the risk of motorcycle crashes, and that must be paused for thought. For more than 50 years, it has been policy in the UK to test drivers for alcohol as a strategy to prevent accidents.

UK authorities are finally starting to notice drivers under the influence of drugs.

The technology there, in the form of DrugWipe, tests for marijuana in saliva and sweat (the test can be configured to detect other illegal substances).

What the public needs is the assurance that all motorists arrested will be tested not only for alcohol but also for drugs, especially marijuana. Failure to do so will cost us all.
