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.)

The main problem at young patients post - LASIK after one year is residual refractive errors.

The method used in Eye Hospital is treatment with implantation of human fresh corneal lenticule (min. -1.50D) taken from myopic patients in post - LASIK patients with residual refractive error (min. +1.0D).

1. The flap of LASIK is lifted, cleaned and then the lenticule is gently inserted. The fresh myopic lenticule is implanted under the guidance of corneal topography in young patients with hypermetropic astigmatism residual refraction, according to the low K value. In cases where astigmatism is not present the lenticule is positioned in central position under the flap.
2. The flap of LASIK is not touched or lifted but using VisuMax femtosecond laser we created the stromal pocket with diameter 8.0 mm (1 mm larger than the optical zone of the donor lenticule) and cap thickness set to 140 μm from corneal surface and 4 mm superior incision. Hinge position flap was set at 90° angle 50° and width 4 mm, side cut angle 90°. The pocket was dissected using a blunt spatula washed with normal saline. The lenticule was held with lenticule forceps and gently inserted into the pocket through the 4 mm superior incision.
