Diffuse lamellar keratitis (DLK) is a sterile inflammation of the cornea which may occur after refractive surgery, such as LASIK. Its incidence has been estimated to be 1 in 500 patients, [ 1 ] though this may be as high as 32% in some cases.
Post-LASIK ectasia is a condition similar to keratoconus where the cornea starts to bulge forwards at a variable time after LASIK, PRK, or SMILE corneal laser eye surgery. [1] However, the physiological processes of post-LASIK ectasia seem to be different from keratoconus.
Some post-LASIK patients see halos and starbursts around bright lights at night. [1] Complications due to LASIK have been classified as those that occur due to preoperative, intraoperative, early postoperative, or late postoperative sources: [54] According to the UK National Health Service, complications occur in fewer than 5% of cases.

After all, LASIK is a completely elective procedure where we are operating on normal, healthy eyes that simply need either glasses or contact lenses to have the best vision, says Dr. Bert.
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses.This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement.
In fact, the U.S. Navy now offers free PRK and LASIK surgery at the National Naval Medical Center to Naval Academy Midshipmen who intend to pursue career paths requiring good uncorrected vision, including flight school and special operations training. [citation needed] The U.S. Air Force approves the use of PRK and LASIK. [24]
Thygeson's superficial punctate keratopathy (TSPK) is a disease of the eyes.The causes of TSPK are not currently known, but details of the disease were first published in the Journal of the American Medical Association in 1950 by American ophthalmologist Phillips Thygeson (1903–2002), after whom it is named.
Laser Blended Vision can be achieved through laser eye surgery, usually performed as LASIK, although surface laser eye surgery PRK or LASEK can be used to produce the effect. Laser Blended Vision works by increasing the depth of field of each eye through subtle changes in the optics of the corneal spherical aberration . [ 2 ]
