-
PRK?
- 30-60s laser UVB ablation of bowman and stroma after removal of central epithelum
- post op sx: pain, bandage cl for epi, stromal haze, decrease CS, halos glare
-
LASIK?
- excimer laser stromal tissue ablation under hinged lamellar flap
- flap repositioned, no sutures required
- short healing time
-
intraop complications of lasik?
- flap button hole
- incomplete cut
- damaged flap
- flap dislocation
- lost flap
-
postop complications of lasik
- epithelial defect
- flap striae
- epithelial ingrowth
- stromal melt
- astig, over/undercx
- DLK
- DE
-
LASEK
