None of the studies reported any complications, however rare but serious potential complications can occur and should be noted. In the studies, CXL was performed immediately after surface ablation, theoretically combining benefits of both treatments. Combined CXL and laser vision correction demonstrated a greater improvement in uncorrected distance visual acuity (UDVA) vs.
Four studies included follow-up duration >1 year. CXL was shown to halt disease progression and stabilise / improve vision in all studies. All of the studies included additional treatments that were used with CXL: photorefractive keratectomy (PRK), phototherapeutic keratectomy (PTK) and intrastromal corneal ring segment (ICRS). decentered grafts closer to limbus confer a greater risk of vascularisation, suture erosion and rejection). Progression of PMD is important because keratoplasty in PMD is associated with significant comorbidity (e.g. Compared to other corneal thinning conditions like keratoconus, corneal steepening in PMD occurs more inferiorly and closer to the limbus.
PMD is a bilateral, non-inflammatory corneal thinning disorder characterised by inferior peripheral corneal thinning 1-3mm from the limbus in the 4 to 8 o’clock position. Fourteen studies were included in this first review examining the use of corneal-crosslinking (CXL) to treat pellucid marginal degeneration (PMD).
