BARCELONA — The new femtosecond laser-based IntraCor treatment for presbyopia is a fast procedure that leads to a significant near visual acuity gain with stable results over a 1-year period, according to a presentation here.

"There is high potential for correction of low refractive errors for presbyopic treatment. Since this a noninvasive procedure, it is safe for the patients, and we don't see any kind of infection, inflammation or weakening of the cornea so far," Mike P. Holzer, MD, said at the European Society of Cataract and Refractive Surgeons meeting.

Dr. Holzer presented 12-month follow-up data of the prospective clinical study of the use of the IntraCor procedure (Femtec femtosecond laser, Technolas Perfect Vision) for the treatment of 25 presbyopia patients. The procedure took a mean time of less than 20 seconds, and the nondominant eye was treated in all patients.

Patients gained a mean of 4.5 lines of visual acuity. Near uncorrected near visual acuity improved from 0.70 ± 0.16 logMAR to 0.27 ± 0.24 logMAR. Mean uncorrected distance visual acuity was 0.11 ± 0.12 logMAR preop and 0.12 ± 0.09 logMAR postop.


Femtosecond lasers took over the LASIK castle from the various keratome devices by creating fine flaps and possible correction of various refractive errors. It seems that their dynamic range might reach the correction of presbyopia, and thus one device will perform the “whole package” justifying the characterization of an ultimate tool in refractive surgery.
