Figure 4: OCT images of the wound after ISCR insertion and suturing of the femtosecond laser-enabled keratoplasty. (A) Posterior gaping (arrow) was seen in 1 of 4 quadrants in the keratoplasty experiment with a 7.5-mm ISCR and a 135º posterior side cut angle. (B) Excellent anterior and posterior apposition was achieved in all quadrants in the keratoplasty experiment with a blunter 117º posterior side cut and an 8.0-mm ISCR.
