SURGICAL TECHNIQUE
We demonstrate adaption of anterior lamellar wedge resection to achieve satisfactory visual rehabilitation in pellucid marginal degeneration. Pre-operative visual acuity was 6/120 due to central scarring due to hydrops.
†
The surgical technique included the accurate measurement of a corneal arc utilising a range of corneal trephines, partial lamellar dissection of extremely thin peripheral corneal wedge with Melles dissectors, paracentesis to enable manipulation of cornea, and peripheral compression sutures.
†
Our video demonstrates successful restoration of physiological anterior segment relationships in a patient with extreme pellucid marginal degeneration. This wedge resection also created a new visual axis above the pre-existing scar, resulting an UAVA of 6/9 at 1 month.
