Lattice degeneration means your retina is not healthy, is thinning, and either has or probably will soon have small holes that will reduce overall vision quality. Lattice degeneration is commonly a contraindication for most refractive surgery procedures; however each individual's circumstances are unique.
A myopic (nearsighted, shortsighted) eye is elongated and this causes stress on the retina. Thinning of the retina is additional stress. The process of refractive surgery is even more stress, but is elective.
The use of an argon laser to cauterize holes in the retina is a common technique to stabilize the problem, however nothing will "cure" the hole, the cauterization, or the lattice degeneration. This laser treatment is to resolve a problem and should be undoubtedly be done if considered appropriate by your ophthalmologist.
We have an article on lattice degeneration and Lasik at http://www.usaeyes.org/faq/subjects/lasik-lattice-degeneration.htm
I highly recommend that you seek the evaluation of a vitreoretinal specialist for care of your lattice degeneration and before any elective eye surgery.
