|Experimental: Suprachoroidal Dissection Instrument||
Device: Suprachoroidal Dissection Instrument (SDI)
The Suprachoroidal Dissection Instrument (SDI) is a manually operated, non-powered, re-usable ophthalmic surgical instrument. The SDI is designed to enter a surgically exposed Schlemm's canal and be advanced up to 90 degrees around the canal from the entry site.
Other Name: SDI
The Suprachoroidal Dissection Instrument (SDI) is a manually operated surgical instrument designed for use within Schlemm's canal. The instrument can access Schlemm's canal through a small ab-externo dissection, allowing use in eyes with scarring due to previous surgery or trauma.
