Deep sclerectomy enhanced with mitomycin C: Long-term outcomes

The two major refinements of DS are viscocanalostomy (VCT) and canaloplasty, both described by Dr Robert Stegmann.¹ In VCT, after a DS procedure, the SC is dilated with a high-molecular weight viscoelastic and in canaloplasty the SC is dilated to 360 degrees and permanently kept open with a tensioning suture. There is an increase in flow through the SC and the normal outflow pathways after these procedures. The subconjunctival bleb is usually not evident in the most cases and in fact is considered to be a complication by some surgeons.
