Figure 1: Consecutive images of a big bubble deep anterior lamellar keratoplasty. During the procedure, Type 2 bubble was created using a 27-G bent needle (note the peripheral formation of the bubble with a clear margin). (a) The small bubble technique confirms the presence of the big bubble. (b) Central stromal tissue was removed successfully with no perforation noted. (c) Irrigation of the surgical interface was performed to remove residual viscoelastic, and this led to a macroperforation. (d) Final image after conversion to penetrating keratoplasty and suturing of a full thinness donor lenticule with 16 interrupted 10-0 nylon sutures. (e)
