Why is there such a difference in the cost of lens implantation surgery? lol

I was told LASIK or LASEK isn't an option, so I'm looking into lens implantation surgery.

The cost varies drastically from hospital to hospital, haha.

Some places are in the 3 million won range, while others are over 5 million won...

I don't understand why the cost is so different.

Is it because of the type of lens or the difference between hospitals?

I'd like to know the standard for lens implantation surgery costs.

I'm debating whether the more expensive option is always better, or if it's okay to go for a reasonable price.
