Corneoplastic Techniques
Mechanical methods Intracorneal segmentsIncisional procedures
Biochemical methods Cross-linking UV lightConductive Keratoplasty (CK)
Mix methods
Excimer laser ablationInlays (Acufocus)
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
800µ base width instead of 600µ
Wider base provides 25% greater implant volume and compensates for reduction of effect in the larger optical zone
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
