Patient selection: exclusion of patients with one or more contraindication
Potential complications of laser refractive eye surgery:
(1) dry eye
(2) haze, glare and problems with night vision
(3) reduction in best-corrected visual acuity
(4) infectious keratitis
(5) diffuse lamellar keratitis
(6) corneal ectasia
(7) problems with the the corneal flap (thin, incomplete and irregular flap creation)
where:
• Problems 4 to 7 can be potentially serious.
• Problems with flap creation are eliminated with flapless laser surgery using femtosecond laser intrastromal vision correction.
• The risk of infectious keratitis can be reduced by preoperative preparation and postoperative antibiotics.
• Problems with haze, glare and night vision are less common with newer laser techniques.
