Transcorneal vitrectomy.. Notes: (A) Irrigation to the anterior chamber was performed with an anterior chamber (23 G) maintainer inserted through a newly created side port at the corneal limbus. (B, C) A vitreous cutter (23 G) and light guide (23 G) were inserted to perform vitrectomy through the corneal incisions created for cataract surgery.

Irrigation to the anterior chamber was then performed with an anterior chamber (23 G) maintainer inserted through a newly created side port at the corneal limbus (Figure 1A). A vitreous cutter (23 G) and light guide (23 G) were inserted to perform vitrectomy through the corneal incisions created for cataract surgery (Figure 1B and 1C).
Phacoemulsification of dropped lens floated on perfluorocarbon liquid (PFCL).. Notes: (A) Lens nuclear fragment floated on PFCL (arrow). (B) After vitrectomy, the dropped lens nucleus was floated on PFCL. Infusion from cannula. (C) Phacoemulsification of dropped lens floated on PFCL. The floating lens nucleus was removed by a biaxial phacoemulsification technique while anterior chamber irrigation continued. Infusion was not performed using an ultrasonic handpiece.

After vitrectomy, the dropped lens nucleus was floated on PFCL (Figure 2A and 2B). The floating lens nucleus was removed using a bimanual phacoemulsification technique while anterior chamber irrigation continued (Figure 2B and 2C).
Phacoemulsification of the dropped lens floated on perfluorocarbon liquid (PFCL). The direction of the infusion is indicated by the arrows.. Notes: (A) The lens fragment could not be visualized below the iris because of the convex shape of the PFCL interface. (B) By changing the direction of the infusion port and fluid stream into the eye, the lens nuclear fragment was able to be located. The lens nuclear fragment that had been hidden by the iris exits from the fluid stream.

Due to the convex shape of the PFCL interface (Figure 3A), the lens fragment was unable to be visualized below the iris. However, it was able to be located by changing the direction of the infusion port and the fluid stream into the eye (Figure 3B).
