Treatment of residual hypermetropic refraction on young patients after LASIK using human fresh corneal lenticule implantation using relex smile surgery
NCT ID NCT04793893
First seen Sep 09, 2026 · Last updated Sep 09, 2026
Summary
LASIK (laser-assisted in situ keratomileusis) is a type of refractive surgery for correction of myopia, hyperopia and astigmatism. Yet approximately 30% of operated patients have symptoms like glare, halos, dry eyes and especially residual hypermetrop refractive errors. Residual hypermetrop refractive errors are difficult to treat surgically, the current treatment is Refractive Lens Implantation - risks are similar to those of cataract surgery (endophthalmitis, loss of accommodation, etc.)
