Is OCT in ophthalmology harmful to eyes? Is there any radiation or anything that hurts your eyes?

Strictly speaking, this can only be considered safe, non-invasive and harmless. There is no literature or data record about the toxicity to retina or whether the lens will be turbid in the later stage. It is impossible to use near infrared rays as detection light without any harm to eyes. If it is completely harmless, it can be completed in a few seconds. Why doesn't the physical examination department of Shanghai Grand Hospital deserve a routine physical examination item, and it costs 700,000 to 800,000? Now people's living standards are not bad, and the physical examination items of one or two hundred are not bad. So there's a problem. But it depends on the specific situation of eye diseases. If you are really ill, don't be afraid of these. After all, it is within the safe dose range. I consulted several big hospitals and hung up several expert clinics, which really worried me. Eyes are a lifetime thing, and you can't be careless. I have met doctors without medical ethics before, so I always ask more questions when I see a doctor now. We should respect doctors, but we should also protect ourselves. When in doubt, it is always right to ask the doctor first and then judge blindly.
