Long-Term Clinical Outcomes of Small-Incision Femtosecond Laser-Assisted Intracorneal Concave Lenticule Implantation in Patients with Keratoconus

Figure 5

The preoperative images showed that corneal thickness was thin. The corneal thickness of the host increased compared with the preoperative level, and no obvious tissue reaction such as infiltrates, ulcer, and neovascularisation from the host cornea was observed (arrows indicate the lenticule and its location in the “stromal pocket”). Throughout the 60-month observation period, the corneal thickness and transparency of the recipient remained stable.
