Effectiveness of intracorneal ring segments for keratoconus

Area of Science:

• Ophthalmology
• Corneal Surgery
• Vision Science

Background:

• Keratoconus is a progressive corneal ectasia leading to visual impairment.
• Current management strategies include refractive correction, corneal collagen cross-linking, and surgical interventions.
• Intrastromal corneal ring segments (ICRS) offer a refractive surgical option for keratoconus management.

Purpose of the Study:

• To review the efficacy of intrastromal corneal ring segments (ICRS) for keratoconus.
• To compare ICRS outcomes with other interventions like contact lenses, keratoplasty, and corneal collagen cross-linking.

Main Methods:

• Literature review of studies evaluating ICRS in keratoconus.
• Analysis of outcomes including visual acuity, refractive error, and corneal topography.
• Comparison of ICRS efficacy with alternative treatment modalities.

Main Results:

• Advancements in ICRS technology (thickness, size) and surgical techniques have expanded their application.
• Combination procedures and refined classification systems enhance ICRS outcomes.
• Recent research confirms the long-term efficacy of ICRS in improving visual acuity, reducing keratometry readings, and correcting astigmatism.

Conclusions:

• Intrastromal corneal ring segments (ICRS) implantation has demonstrated significant short-term and long-term efficacy in patients with keratoconus.
• ICRS represent a viable option for visual rehabilitation in keratoconus patients.
