Long-Term Results in Treating Emmetropic Presbyopia With Small-Aperture Inlay
Purpose
Clinical evaluation of the long-term stability of presbyopia correction with a small aperture corneal inlay.
Methods
Prospective, non-randomized multi-center clinical trial of 154 naturally occurring emmetropic presbyopes implanted monocularly in the non-dominant eye with a small aperture inlay for correction of presbyopia. Additional inclusion criteria were uncorrected near visual acuity (UCNVA) of worse than 20/40 and better than 20/100 and a best-corrected distance visual acuity (BCDVA) ≥ 20/20 in both eyes, with a spherical equivalent between +0.50 D to -0.75 D. Visual acuity, refractive stability and satisfaction were evaluated.
Results
Mean UCNVA improved 5 lines from J8 at pre-op to J2 at 3-years post-op. Mean UCDVA was virtually unchanged from 20/18.5 to 20/20. 92% of patients were 20/25 or better at 3-years post-op. 96% were within ± 1.00D of intended target. No patient sustained a loss of 2 or more lines of BCDVA at 3 years.
Conclusion
Implantation of a small aperture inlay improves near visual acuities while retaining good distance vision over three years follow up.
