Femtosecond laser presbyopia correction yields stable long-term outcomes
CHICAGO — A femtosecond laser intrastromal presbyopia procedure improved near vision and yielded high patient satisfaction, according to a study.
Claire Hartnett, MD, presented 2-year visual and functional outcomes of the IntraCor procedure at the American Society of Cataract and Refractive Surgery meeting here.
“IntraCor is an intrastromal procedure performed with a femtosecond laser which results in a defined change in central corneal curvature and changes the refractive power of the cornea,” Dr. Hartnett said.
The study included 67 eyes of 67 patients with a mean age of 52 years who underwent the IntraCor procedure in the nondominant eye with the Technolas femtosecond laser (Technolas Perfect Vision).
Patients underwent comprehensive visual examinations preoperatively and at 1 day, 1 week, and 6, 12 and 24 months postoperatively. Mean follow-up was 24 months.
Preoperative mean uncorrected near visual acuity was N18 with a mean required near addition of +2.1 D.
Mean uncorrected near visual acuity remained stable at N5 for up to 2 years after the procedure.
Functional stability and patient satisfaction remained high at 2 years, Dr. Hartnett said.
Data showed that 16% of patients reported a reduction of distance visual acuity; 60% of patients needed reading glasses in low lighting, Dr. Hartnett said.
