Apart from the usual risks of Lasik (dry eyes, glare or haloes), patients with high myopia have a unique set of concerns including a higher risk of residual refractive error (necessitating Lasik enhancement), risk of post-Lasik ectasia and recurrence of refractive error.
Patients with high myopia are also advised that Lasik does not structurally change the rest of the eyeball, hence they should be aware that their risk of all other diseases including cataract, glaucoma and retinal detachment remains unchanged (higher than the normal population) following successful Lasik surgery.
