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).

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.
