So my doctor told me to buy a VCD/VED. I couldn't find one in shops so I am thinking of ordering online. It is a bit expensive so just wanted to confirm if this is an actual VCD. I don't have any mode of communication with the doctor.

Note: I'm from India.

Off hand and having no familiarity with any of those, I'd say they all look like novelty grade or sex shop grade pumps. I can't offer any advice on which one if any to purchase. Sorry!

I'm with bldoink on those pumps.

For what purpose is your doctor recommending a VED/VCD?
If your doctor wants you to use the pump with a constriction ring, then a medical grade VED is called for.
If the purpose is more for exercise and to help blood flow and not use a constriction ring, then the pumps
you are looking at may be adequate.

You should ask your doctor for further clarification.

If you need to use the pump to pump up an erection and maintain your erection for penetration, you need a VED pump device that allows you to slide a constriction band onto the base of your erection.

If you need to use the pump for therapy, you need a pump with a vacuum gauge.

Which are you looking for?

Basically Doctor wants to check if a VED can help me have sex. I'm pretty sure it won't but I want to do as he says. I'm sure he means a medical grade VED. After VED doesn't work, he will recommend me for implant.

I'm sure he means a medical grade VED

I use an Encore deluxe. Cost was $125 us dollars and was the best $125 I have ever spent.
Some medical supply stores can give you an idea of what is available. Here's one of many.
