Corneoplastic Techniques

Mechanical methods Intracorneal segmentsIncisional procedures

Biochemical methods Cross-linking UV lightConductive Keratoplasty (CK)

Mix methodsExcimer laser ablationInlays (Acufocus)

Page 4: 150°X 200 m

Optimized prismatic design

Scalene triangular shape SI-6 compared to Isosceles triangle in SI-5.

Improves effect and optimizes total internal reflection, reducing glare and halos

Page 5: 150°X 200 m

800µ base width instead of 600µ

Wider base provides 25% greater implant volume and compensates for reduction of effect in the larger optical zone

Page 6: 150°X 200 m

When should Keraring SI-6 implantation be considered?

Mesopic pupil diameter ≥ 5mm BCVA is ≥ 0.6 Moderete Sphere ≤ 5 D Cylinder value is ≤ 5 D Segment thickness should not exceed 60% of the

minimum pachymetry at the 5.5 optical ring zone When PRK is planned as a second procedure. When phakic IOL implantation is planned as a

second procedure

New SI-6 KeraringEarly Conclusions Keraring SI-6 achieves Corneoplasty purposes. Keraring SI-6 is not intended to replace the IS-5,

but rather intends to offer the surgeon additional tools to customize the corneal remodeling according to each individual patient’s needs
