Nose revision surgery in Korea - scared but need advice

I had rhinoplasty done 5 years ago and my implant has started to become visible through my skin, especially at the tip. I can actually see the outline of the implant now and it is getting worse. I have been told I need revision surgery to correct this. I am considering going to Korea for the revision as I have heard they handle complex cases well. Has anyone had nose revision surgery in Korea for implant-related complications? What was the process like? Did they remove the old implant and replace it with something else? I am really anxious about going through surgery again but I cannot live with how my nose looks now.
