ABSTRACT
Newer forms of lamellar keratoplasty techniques have emerged in the last decade or so revolving around the concept of targeted replacement of diseased corneal layers. These include anterior lamellar keratoplasty (ALK) techniques that aim to selectively replace diseased corneal stroma and, endothelial keratoplasty techniques aiming to replaced damaged endothelium in endothelial disorders. ALK surgery has a distinct advantage over penetrating keratoplasty (PK) in that it minimizes unnecessary replacement of the unaffected healthy endothelial layer thereby almost eliminating the risk of endothelial rejection, a major cause of graft failure in PK. Overall it provides increased life expectancy to the graft and with advancements in the surgical technique and instrumentation for ALK, the visual outcomes are now comparable if not better to standard PK. There are several forms of ALK procedures that have evolved to cater to a wide range of stromal disorders. This article reviews the various emerging techniques of anterior lamellar surgery, its indications and visual outcomes, to emphasize the shift from PK to ALK for stromal disorders with a healthy endothelium.
