1. Indications of Lamellar Keratoplasty Shibali Kashyap MBBS, 3rd year

2. Lamellar Keratoplasty Partial thickness replacement of only part of the cornea Lamellar Keratoplasty Partial Thickness DESK (Descemet’s stripping endothelial keratoplasty) DALK (Deep Anterior Lamellar Keratoplasty) Lamellar Keratoplasty Partial Thickness DSEK (Descemet’s stripping endothelial keratoplasty) DALK (Deep Anterior Lamellar Keratoplasty)

3. DALK Removal of corneal tissue from epithelium upto deep stroma ( i.e. anterior 3 layers). Indications : Superficial ⅓ stromal corneal opacity, granular dystrophy Marginal corneal thinning or infiltration as in recurrent pterygium, marginal degeneration Indicated in keratoconus with acute hydrops Localised thinning of descemetocele formation

4. DSEK Removal of only endothelium and Descemet’s membrane ( i.e. posterior 2 layers). Indications : Pseudophakic bullous Keratopathy Iridocorneal endothelial (ICE) syndrome Endothelial fatigue in the setting of prior intraocular surgery Endothelial dystrophies such as Fuchs corneal dystrophy and posterior polymorphous corneal dystrophy
