Post Lasik

Can Lasik - whether the spike in pressure from the suction ring or the laser itself create the onset of any eye diseases such as Glaucoma, macular degeneration or any other things that come to your mind? Wouldn't any damage be known almost immediately and in terms of eye diseases - is it even possible for lasik to induce them?
Also, how long does it take for the corneal nerves to regenerate and how is one's vision affected while they heal if at all (peripheral vision, halos, ghosting - do the corneal nerves have anything to do with vision imperfections?
Post Lasik follow-ups - Should one's doctor look for all things or will they only go off of symptoms?
Thanks

Lasik does not cause disease per se. Lasik can cause damage. Lasik can exacerbate previously existing disease. Lasik can create an environment where opportunistic disease may occur.

Damage or the exacerbation of previously existing disease may not be immediately evident.

Subbasal corneal nerves regenerate to preoperative levels at about three years postop for PRK, LASEK, and Epi-Lasik and at about five years for Lasik and IntraLasik. Corneal nerve sensitivity - the important component - commonly returns withing the normal six month healing process.

Reduced corneal nerve sensitivity may contribute to Lasik induced temporary dry eye.

The changes to the nerves caused by refractive surgery would not directly cause problems with peripherial vision, halos, or ghosting, but delayed restoration of corneal nerve sensitivity can contribute to problems such as dry eye, which definately can contribute to problems with vision quality.

Keep in mind that of all refractive surgery procedures and all patient types, about 3% have an unresolved complication at six months postop, with about 0.5% being serious problems requiring either extensive maintence or invasive procedures to manage or resolve.

Both. A comprehensive examination will look for problems that are not symptomatic (such as high intraocular pressure), plus the doctor will seek the cause and treatment of problems reported by the patient.

So to your knowledge Lasik doesn't do anything to the eye other than the cornea itself?
Thanks

Can it do damage to other parts of the eye (i.e. optic nerve, macula, retina, tec.)?

There are multiple areas affected during Lasik, however numerous studies and multiple millions of surgeries have shown that Lasik is safe, effective, and predictable when performed on a healthy eye.
