Presbyopia came early, and I heard there might also be glaucoma...

Hello, I went to get my eyes checked and the doctor said that there isn't much angle and that my intraocular pressure is high, which could lead to blindness. He mentioned that glaucoma might develop and immediately scheduled a surgery date.

They say they make a hole in the eye with a laser, but it's really scary.

The doctor talks as if it's nothing serious.

Is it okay to undergo this procedure?
