Novel procedures continue to provide refractive patients with surgical options that are safe, virtually painfree, and with reduced risk of postoperative complications.
The Switzerland Eye Research Institute, for one, is oriented toward less-invasive corneal techniques that reshape the corneal surface without penetrating the eye. Femtolasik and Femtolasik Xtra are established procedures worldwide,1,2,3 and involve customized reshaping of the cornea to eliminate myopia, hyperopia, astigmatism, and presbyopia.
Over the past six years, we have been approaching corneal surgery in Lugano using a novel procedure that unites Femtolasik and transepithelial crosslinking.
This combined technique is known as Femtolasik Lux, and aims to increase the stability of the visual outcome in patients, thereby maintaining a healthy and robust cornea.
Femtolasik Lux is a non-invasive, “no-touch” procedure, which—at no point touching the eye with any instrument—uses three different light sources to resolve any visual defect in a few minutes without pain.
This procedure leads to a final sharp refractive result, provides a stronger corneal tissue that is less vulnerable to curvature change, and reduces refractive error regression and incidence of corneal ectasia.
Safety, effectiveness, and excellent long-term results have been demonstrably achieved.
There is a protocol for this technique called the Lugano Protocol. ParaCel eye drops are used to soak the corneal epithelium for a time that cn range from 30 to 50 seconds after the repositioning of the flap.
