Some complications of PRK include: Long healing period Pain Glare, halos, or starburst Aberrations Under- or over-correction Recurrence of myopia Increased intraocular pressure Corneal haze Scarring Reduced best corrected visual acuity...

The incidence of flap complications has been estimated to be 0.244%.[16] Flap complications (such as displaced flaps or folds in the flaps that necessitate repositioning, diffuse lamellar keratitis, and epithelial ingrowth) are common in lamellar corneal...

The incidence of diffuse lamellar keratitis (DLK)[6], also known as the Sands of Sahara syndrome, has been estimated at 2.3%.[21] When diagnosed and appropriately treated, DLK resolves with no lasting vision limitation. The incidence of infection...

The incidence of epithelial ingrowth has been estimated at 0.1%.[21] Glare is another commonly reported complication of those who have had LASIK.[25] Halos or starbursts around bright lights at night are caused by the irregularity between the lasered...

Although relatively uncommon, the following are some of the more frequently reported complications of Epi-LASIK [1]: Over/undercorrection Visual acuity fluctuation Halos around light sources Starbursts around light sources Decentered ablation...
