[Intracorneal ring segments in keratoconus management]

Area of Science:

• Ophthalmology
• Corneal Surgery
• Vision Science

Background:

• Keratoconus management has advanced significantly with Intracorneal Ring Segments (ICRS) technology since the 2000s.
• ICRS offer customizable parameters (arc length, thickness, diameter) to tailor visual outcomes.
• Individualized implantation strategies are continuously refined based on patient-specific corneal topography and tomography.

Purpose of the Study:

• To review current clinical practices for visual rehabilitation in keratoconus patients.
• To summarize the application of Intracorneal Ring Segments (ICRS) and combined procedures.
• To provide insights into the effects of ICRS on the keratoconic cornea.

Main Methods:

• Review of existing literature and clinical practices regarding ICRS implantation.
• Analysis of various ICRS types and their impact on visual parameters (spherical equivalent, keratometry, asphericity).
• Examination of combined surgical procedures involving ICRS, corneal collagen cross-linking, and refractive surgery.

Main Results:

• ICRS technology has evolved, offering diverse options for keratoconus management.
• Surgical implantation of ICRS is standardized with a low complication rate.
• Combined procedures are increasingly utilized, necessitating a thorough understanding of ICRS effects.

Conclusions:

• ICRS are a valuable tool in the modern management of keratoconus.
• Personalized ICRS implantation strategies enhance visual rehabilitation outcomes.
• Knowledge of ICRS effects is crucial for successful combined surgical interventions in keratoconus.
