Will having laser eye surgery prevent me from having other eye diseases later?

No. With the exception of Refractive Lens Exchange (RLE) which prevents formation of cataracts, laser eye surgery does not prevent diseases like glaucoma, retinal detachment, or macular degeneration. LASIK is “disease neutral,” meaning that it does not cause or prevent these diseases. Someone who has had LASIK can develop these eye diseases and be treated just like a normal-sighted person can develop and be treated for a disease.
