and wavefront-guided treatment following multiple corneal refractive procedures," Journal of Cataract and Refractive Surgery, vol.
(1) It has since been used in corneal refractive surgery to correct refractive errors using the technique photorefractive keratectomy (PRK) and successfully treat a variety of superficial corneal pathologies through phototherapeutic keratectomy

mode using the NIDEK CXIII excimer laser.," Journal of Refractive Surgery, vol.
Food and Drug Administration approved the 193 nm argon-fluoride excimer laser for phototherapeutic keratectomy (PTK) procedures in 1995, a variety of anterior corneal pathologies have been treated by PTK with promising results .

(PTK) using excimer laser technology involves treating Bowman's layer, resulting in a modified, roughened surface to anchor the corneal epithelium.
Given his subjective complaints and evidence of progressive haze that was refractory to topical corticosteroid therapy, he was referred for transepithelial phototherapeutic keratectomy
(PTK); all laboratory tests for systemic autoimmune disease were negative.
Alternatively, excimer laser phototherapeutic keratectomy
maybe used to clear the visual axis.
Surgical intervention, such as anterior stromal puncture (outside the visual axis), YAG laser micropuncture, cautery, alcohol-assisted epithelial debridement, and excimer laser phototherapeutic keratectomy
(PTK) can be of benefit in reducing the rate of recurrent erosions.
Treat with corticosteroid eye drops or phototherapeutic keratectomy
This is illustrated by the hyperopic shift that typically occurs following phototherapeutic keratectomy
is a useful treatment for epithelial basement membrane dystrophies and recurrent erosion syndrome.
