Abstract Details


To evaluate the outcome of pupillary zone sparing corneal epithelium debridement for collagen cross linking in keratoconus


Dr Om Parkash Eye Institute, Amritsar, India


This was a retrospective study in 522 eyes presenting with keratoconus undergoing collagen cross linking (C3R) from February 2012- February 2017. After putting anesthetic eye drops, epithelium was mechanically debrided using a blunt hockey stick knife. Approximately central 2-3 mm zone corresponding to the pupillary axis was spared from debridement. Dresden protocol for C3R was followed in each eye following this. Post C3R, progression in keratoconus was evaluated using Pentacam HR at an interval of 3 months, 6 months, 12 months and 18 months


In the immediate post-operative period, pupillary zone showed minimal haze as compared to the rest of the cornea from where epithelium was debrided. Post C3R, no significant progression in keratoconus was observed at a follow up of 18 months.


Pupillary zone sparing partial corneal epithelium debridement for C3R using Dresden protocol causes minimal haze in the pupillary zone without compromising good outcome
