Outcome of pupillary zone sparing partial corneal epithelium debridement for collagen cross-linking (C3R) in keratoconus

In this video, the authors evaluated the outcome of pupillary zone sparing partial corneal epithelium debridement for C3R to minimise the associated visual complications of standard conventional cross linking. Dresden protocol for C3R was followed after removing epithelium sparing 2-3 mm central zone. Post C3R, Wong Baker Pain scoring(WB) was assessed. Visual, keratometric and haze outcomes were evaluated. There was minimal pain postoperatively & pupillary zone showed minimal haze. Demarcation line was observed 4-8 weeks postoperatively. Stable keratometry was noted at 18 months postoperatively. The authors conclude that Pupillary zone sparing partial corneal epithelium debridement for C3R using Dresden protocol causes minimal haze in the pupillary zone without compromising good outcome
