The corneal endothelium of the lenticule
was assessed by AS-OCT and HRT-III confocal microscopy.
Effect of suction on macular and retinal nerve fiber layer thickness during femtosecond lenticule
extraction and femtosecond laser-assisted laser in situ keratomileusis.
In 1 eye of 1 patient, a 1 mm tear occured in the sidecut intraoperatively, while removing the lenticule
. In the same eye, metallic deposits were observed postoperatively in the interface near the sidecut (Figure 3).
(8) In this technique, lenticules
of peripheral corneal epithelium with superficial stroma were grafted.
After cataract extraction and intraocular lens implantation, we used the same scleral tunnel to insert the donor lenticule
. The use of a large scleral tunnel and an anterior chamber glide does not require folding of the graft thereby minimizing the risk of endothelial trauma.
Such materials must be optically clear, laser adjustable, gas permeable, structurally stable and capable of transporting nutrients from inside the eye to the epithelial cells growing outside the lenticule
, he notes.
(1,2) Hence SmILE is ideal in this scenario as disruption to the corneal nerve plexus is minimised by removing a lenticule
of stromal tissue through a small peripheral incision, rather than creating a flap or removing the epithelium.
Healthy animals were randomly assigned into TE-treated groups or the untreated human corneal lenticule
group consisting of five animals.

extraction and femtosecond laser-assisted LASIK for high myopia correction," Contact Lens & Anterior Eye, vol.
The small-incision lenticule
extraction (SMUE) procedure is a relatively new development in refractive surgery and has been introduced into practice in some Turkish centers in recent years.
In one patient, where limbal stem cell transplant was required, the lenticule
of conjunctivolimbal tissue was harvested from the contra lateral normal eye and was sutured at limbus after HAMT with 10-0 nylon sutures.
