Are there likely to be any long term unsuspected side effects of laser eye surgery?
Lamellar surgery, which is the procedure of creating the flap, has been performed for over 40 years, and we have follow-up results. The excimer laser has been used on the cornea for over 20 years, and for LASIK for over 15 years. There have been no long-term toxic effects documented. There is a very rare condition called iatrogenic keratectasia, where myopia can return, accompanied by a reduction in visual quality. The cornea can also stretch in the months following surgery, which can result in a return of myopia and astigmatism. However this is when inappropriate surgery is performed, and we do our best to ensure this never happens. Your risks of surgery will be discussed with you further at your consultation.
