Will laser surgery help?

Hi all,
I have been suffering from intraocular pressure, and my doctor has suggested me to undergo surgery. But, I am not sure if this will cure it completely. Because my ocular nerve is also damaged. I am planning to undergo laser surgery from an eye center in Washington. I wanted to know, has anyone else faced such an issue ? Will undergoing surgery help in reducing the pressure ? And, what all to be kept in mind while going for the surgery ? Looking forward to your advice.
