With that in mind you'll understand why I feel I think the word "occasionally" (my highlight below) should be read with sincere skepticism.
Simultaneous corneal inlay implantation and laser in situ keratomileusis for presbyopia in patients with hyperopia, myopia, or emmetropia: Six-month results.
To evaluate the safety and efficacy of simultaneous Kamra corneal inlay implantation and laser in situ keratomileusis (LASIK) for the treatment of presbyopia in emmetropic, hyperopic, or myopic patients.
Private center, Tokyo, Japan.
Patients had bilateral LASIK with simultaneous implantation of a corneal inlay in the nondominant eye to treat presbyopia and ametropia between September 2009 and April 2010. The efficacy and safety were determined by the spherical equivalent (SE) in the eye with the inlay.
The study enrolled 360 eyes of 180 patients with a mean age of 52.4 years ± 5.1 (SD) (range 41 to 65 years). Sixty-four patients were available for the 6-month postoperative examination. The mean logMAR uncorrected near visual acuity in the eye with the inlay improved 7 lines in hyperopic eyes, 6 lines in emmetropic eyes, and 2 lines in myopic eyes. The mean logMAR uncorrected distance visual acuity improved by 3 lines, 1 line, and 10 lines, respectively.
Simultaneous intracorneal inlay implantation and LASIK to treat presbyopia with emmetropia, hyperopia, or myopia was clinically safe and effective, yielding improvement in distance and near visual acuity. Patients were satisfied with decreased dependence on reading glasses regardless of the preoperative SE range. However, postoperative symptoms, such as dry eyes, halo, glare, or night-vision disturbances, occurred occasionally.
