At eight months post Lasik the vast majority of your healing has occurred, but not all. If you read about Lasik flap healing
you will see that you are in the final stage of flap healing, but that stage can last up to two years. There are several peer reviewed studies that show corneal nerve density returns to pre-Lasik levels after about three years. Nerve density is not as important as nerve sensitivity, but it is a measurement of how the cornea heals after Lasik.
As much as one may want to blame the surgeon - and that is where blame would be made - it is quite possible that before surgery you demonstrated no clear indication of susceptibility to long-term Lasik induced dry eyes. Even though the incidence of long-term problems is relatively rare, it's 100% when you have it.
There is no reason to abandon hope, and good reason to expect the desired - albeit late - outcome.
And don’t be a stranger. You have become quite knowledgeable about Lasik (probably much more than you desired) and your experiences will be appreciated by others in this forum.
