Intrastromal corneal ring technology: results and indications

Area of Science:

• Ophthalmology
• Biomedical Engineering

Background:

• Intracorneal ring technology has advanced significantly over the last decade.
• This technology is used for correcting refractive errors, particularly myopia.

Purpose of the Study:

• To evaluate the safety and efficacy of Intrastromal Corneal Ring and Intrastromal Corneal Ring Segments for myopia correction.
• To assess the long-term stability and predictability of the refractive outcomes.

Main Methods:

• Clinical trials regulated by the US Food and Drug Administration.
• Surgical implantation of Intrastromal Corneal Ring and Intrastromal Corneal Ring Segments.

Main Results:

• The surgical procedure is safe, easily performed, and yields excellent visual results.
• Best spectacle-corrected visual acuity is preserved postoperatively.
• Stable and predictable correction is achieved for several years.
• Enhancements via device exchange and removal for refractive reversal are feasible.

Conclusions:

• Intracorneal ring technology is a promising option for low to moderate myopia correction.
• The devices offer a safe, effective, and reversible solution for refractive error management.
