ter PTK is typically delayed, too. It may require
up to 3 weeks [6]. Recurrence rates are steady,
but fairly slow.
We performed a study to compare the visual
and refractive outcome after PTK for superficial

(b) no recurrence 4 years after excimer laser PTK [29].

corneal opacities in granular and lattice dystrophy.
PTK was performed in 62 eyes of 40 patients
(granular dystrophy [n=50] and lattice dystrophy
[n=12]) after epithelial debridement and pannus
removal. Recurrence, if any, was noted during a
