Tear VIP concentration correlated negatively with corneal ablation depth (AD). Tear VIP concentration increased significantly after both LASEK and FS-LASIK, with the highest concentration observed 1 week post-surgery ( P ≤ 0.05). After conducting an intact ophthalmic examination and collecting relevant surgical data, all subjects were examined for VIP concentration in their tears using ELISAs, tear-film breakup time, ocular staining and ocular surface disease index questionnaire before surgery and 1 day, 1 week, and 1 month post-surgery. In this prospective, non-randomized, longitudinal cohort study, 23 and 22 subjects were recruited and underwent LASEK and FS-LASIK, respectively. Asim Piracha.To explore the changes in vasoactive intestinal peptide (VIP) concentration in tears post laser-assisted sub-epithelial keratomileusis (LASEK) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) surgeries and related factors, possible association between postoperative dry eye symptoms and VIP concentration in tears, and factors influencing dry eye symptoms after different periods post LASEK and FS-LASIK surgeries.

John-Kenyon has a history of being at the leading edge of ophthalmic technology. Their vision continued to improve over the next several weeks and months.1Īfter extensive training and research, John-Kenyon is now performing the procedure on patients dealing with presbyopia. In the FDA clinical study, within one week after the procedure patients on average gained 5 lines of near vision on an eye chart without the need for reading glasses.
We’re now able to offer an option for improved vision in a quick, relatively painless procedure.” These are active people who don’t want to constantly grab for, or look for, readers. “For years, we’ve seen patients in their 40’s and 50’s who want to reap the benefits of LASIK but who are no longer candidates for it. “It was an extremely exciting day to not only perform the procedure but to see the reactions of our first two patients,” said Dr. Asim Piracha performed Kentucky’s first two procedures on and both patients are already experiencing the results. The outpatient procedure takes about 10 minutes and patients return to most of their daily activities the next day.ĭr. Approved by the FDA in June 2016, the Raindrop is the world’s first inlay to change the shape of the cornea (the clear, front part of the eye) to improve near vision and it is designed to help reduce or eliminate the need for reading glasses. The procedure can be a game-changer for those who need reading glasses to see their phone or read a newspaper, menu or computer screen. The all-new procedure corrects near vision, or presbyopia, and can reduce or eliminate dependence on reading glasses. Asim Piracha, a refractive specialist and the medical director at John-Kenyon, performed Kentucky’s first Raindrop Near Vision Inlay Procedure.
