How to find the right Intracorneal Rings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Intracorneal Rings
- Indication
- Use for keratoconus or ectasia with a clear central cornea in patients who are intolerant of contact lenses. Rings reshape the cornea but do not treat scarring or halt progression on their own.
- Segment selection by nomogram
- Choose segment thickness, arc length and number from the manufacturer's nomogram using topography and refraction. Getting this wrong causes under- or over-correction and induced astigmatism.
- Corneal thickness at the channel
- Confirm adequate pachymetry along the planned channel depth per the manufacturer's labeling. A thin cornea risks perforation and segment extrusion.
- Channel creation method
- Confirm the system supports your femtosecond laser or mechanical dissection technique. Channel dimensions must match the segment profile.
Brands that matter
- Intacs: The original FDA-approved intracorneal ring segments.
- Keraring: Mediphacos segments, widely used outside the US.
- Ferrara Ring: Triangular-profile segments with their own nomogram.
What to avoid
- Buying segments outside an authorized surgical supply channel.
- Ring implantation in corneas with central scarring.
