Questions 10
What are the risks of going abroad for cataract surgery?
You have to look at two things. The most important thing when it comes to the happiness and success of the patient is, The surgeon and The equipment. So of course whether it’s cataract surgery, heart surgery or hip surgery, it is probably dollar for dollar whether you do these things in Malaysia or Singapore. The most important is that you get the doctors qualifications and the equipment.
How do I know if I'm suitable for LASIK?
At the moment we are doing $5 screening because a lot of patients pay $130 consultation fees just to find out they are unsuitable for LASIK. The main determinant for the LASIK procedure is the thickness of the cornea. Only about 5% may not be suitable for LASIK.
What is the risk of bladeless LASIK for older adults?
From my experience, the risk of corneal decompensation is the same as young people. If you don’t screen correctly you will allow someone who shouldn’t do LASIK undergo the procedure, you will get in trouble. I think the success rate is exactly the same. You could argue that maybe it’s different if we look at the younger patients in their 20s when they recover within 24 hours, compared to older people who recover just one day or two later.
Is it possible to not have cataract for an entire lifetime?
No. It's a question of degree. At the age of 67, the likelihood is that 80% of people will have some degree of cataracts. So, sometimes they grow very slowly from the outside approaching the center. The only symptoms he might show are only might occur only under certain lighting conditions early symptoms of cataracts are a little bit of glare and shadowing or hazy vision. These are the mild and early signs of someone with maybe the tiniest bit of cataract but is not yet hindering his vision because it is not yet growing so rapidly.
Is it true that your colleagues in ophthalmology mostly wear contacts and glasses and not opt for Lasik?
There are still eye specialists wearing glasses. There are many specialists that we have done LASIK for but there are still many specialists that are wearing glasses. So I really think it's really a freedom whether you want that lifestyle choice. It is a cosmetic procedure like some people have done their double eyelids. So I think, when LASIK started back in the 1990s, doctors did not have the scanning equipment to determine which corneas were the safest.
I have myopia. Can I go through with myopia surgery?
80% of Singaporeans are myopic, 20% are long-sighted, and about 40% will have astigmatism. Think of it as a 4 in 1 procedure. Not only do you remove cataracts, but you also eliminate and reduce myopia and reduce lao hua all in one procedure. This will leave you entirely spectacle free! These changes will last a lifetime; cataracts will never come back again and myopia and astigmatism will never return anymore.
If I have corrected my myopia can I develop lao hua yan (presbyopia)?
If the cornea has sufficient thickness left you can still do some LASIK. Especially if you have not got cataracts because you are still relatively young (around 50 years of age). If the cornea has no more thickness left because of the first LASIK, then you cannot undergo any further LASIK and should get a lens implant.
How much expected improvement to vision can I expect after cataract surgery?
International standard for perfect vision is 20/20 or 6/6 in British terms. It depends on how the cataract is affecting the vision, not only in quality but also in quantity. After the surgery you will have a clear lens in place.
Does cataract happen only when you are a certain age or can it occur when you are a child?
It’s an age-related process but even juveniles and babies can develop cataracts at a much younger age. Probably 99% of cases are with patients over the age of 40. Cataract is usually an ageing problem commonly presented in older patients. Some are born with congenital cataract and usually this is due to some disease. For example, the mother has chickenpox during pregnancy and this causes some lens proteins in the eye to become faulty.
