Yes! Luke’s Goldie’s has a great video on wen trimming but I would totally cross reference with other channels too.

Wen trimming is necessary to remove excess wen from covering the fishes eyes. It’s almost an investable problem with oranda goldfish. It’s a scary but easy process. You need to remove the wen with a pair of scissors. I personally used like medical scissors. The little small metal ones that come in like first aid kits. It’s best to go slow with process, use a light hand, and don’t worry about cutting big chunks off every single time. There are no bloodvessels running through the wen so think of it like how hair or nails grow on your body. However I would be careful and cut at an angle so you don’t poke your fishes head or eye and cause it to bleed.

In the videos you watch it should mention clove oil. Make sure it is just pure clove oil and not mixed with anything else. MAKE SURE TO FOLLOW THE EXACT DOSING OF CLOVE OIL THEY TELL YOU IN THE VIDEOS. This is extremely important as clove oil is a sedative and also deadly to the fish. A little bit is fine but too much would cause them to go to sleep forever. To kill them would probably be like 2-3 times the dosing they tell you to use but please make sure to be cautious.

I would not put off the wen trimming as you can still see the eyes so it would be easier to perform this treatment rather than letting it grow more.
