“…Three of these are large cohort studies that include analyses on OSD patient subgroups (Severinsky and Millodot, 2010;Stason et al, 2010;Gumus et al, 2011), while three more reports examined the effect of scleral RGP lenses in populations with one specific surface disease (Schornack et al, 2008;Tougeron-Brousseau et al, 2009;Rathi et al, 2011). Also included in the twelve publications are four case reports or series of single disease entities reporting outcome measures demonstrating the effectiveness of scleral RGP lenses (Schornack and Baratz, 2009;Grover et al, 2010;Gumus et al, 2010;Schornack, 2011), and two case series describing innovative uses of scleral lenses in patients with other ocular complications secondary to OSD (Lim et al, 2009;Tanhehco and Jacobs, 2010).…”
