A femtosecond laser-based intrastromal procedure yielded good and stable visual acuity outcomes at 1 year postoperatively in the treatment of presbyopia, according to a study.
“With regards to presbyopia correction, the intrastromal IntraCor procedure significantly improved [uncorrected near visual acuity] in most patients with only a few side effects,” the researchers wrote. “It presents an interesting option for the treatment of presbyopia.”
The prospective, multicenter, nonrandomized trial included 63 eyes of 63 patients with mild hyperopia and a mean age of 54 years. The Technolas femtosecond laser (Technolas Perfect Vision) was used to perform the IntraCor procedure in the nondominant eye.
Near and distance visual acuity tests, slit lamp examinations, and corneal topography measurements were conducted at 1 day, 1 week, 1 month, 3 months, 6 months and 1 year.
Outcomes for 58 eyes (92.1%) were available at 1 year postop, and median uncorrected distance visual acuity and corrected distance visual acuity remained stable. Median spherical equivalent changed from +0.63 D preop to 0 D postop.
Median uncorrected near visual acuity increased significantly from 0.7 logMAR to 0.2 logMAR, and eyes gained a median of four lines.
Ring cuts were faintly visible at 12 months, and 7.1% of eyes lost two lines of corrected distance visual acuity.
Overall patient satisfaction with the procedure was approximately 80%.
