Abstract

PURPOSE: To determine the safety, efficacy, and stability of intrastromal corneal rings 10 years after placement for myopia. METHODS: Ten eyes with myopia treated with the placement of 360° complete intrastromal corneal rings with the ends sutured together were evaluated at 10-year follow-up for the following: unconnected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), manifest refraction spherical equivalent (MRSE), induced manifest refractive cylinder, keratometry readings, slit-lamp findings, and ultrasound central pachymetry. Ten-year data were compared to 1-year results to assess visual stability over time. RESULTS: No statistically significant difference was noted between UCVA at 1 year and 10 years. At the 10-year examination, 90% of patients had BSCVA ≥20/25 and 100% had BSCVA ≥20/30. There was no statistically significant difference between MRSE at 1 year and 10 years. At the 10-year examination, induced manifest refractive cylinder was >1.00 diopter (D) in 0% of eyes and ≤0.25 D in 60% of eyes. There was no statistically significant difference between mean central keratometric power at 1-year follow-up compared with 10-year follow-up. No statistically significant difference was noted in central corneal thickness between 1 and 10 years in the eyes studied. CONCLUSIONS: Intrastromal corneal rings are an effective and stable method of correcting mild myopia based on optic parameters.
