(A-H) Intraoperative photographs. (A) Lens nucleus is crushed using a microvitreoretinal blade and a 20-gauge needle. (B) Lens material is removed using vitreous cutter. Care is taken not to damage the anterior capsule. (C) Viscoelastic material is injected into the anterior chamber through a 2.8 mm superior clear corneal incision. (D) A puncture is made on the remaining anterior capsule using a bent needle. (E) Continuous curvilinear capsulorhexis is being done on the anterior capsule. White arrows indicate the margin of the capsulorhexis being made. (F) An IOL is placed in the ciliary sulcus initially, then the IOL optic is captured through the capsulorhexis. (G) The successfully captured IOL makes an oval capsulorhexis margin. Inset: A graphic illustration of the shape of the capsulorhexis margin (green line) and the position of the haptics (purple lines). (H) The captured IOL-capsule diaphragm maintains stability during fluid-air exchange.. Abbreviation: IOL, intraocular lens.

After a core vitrectomy was performed, the nucleus of the lens was initially crushed with a microvitreoretinal blade and a 20-gauge needle introduced through a superotemporal and superonasal sclerotomies, respectively (Figure 1A). The nucleus was then removed with a fragmatome and a vitreous cutter through the pars plana, and cortical cleaning was performed using the active vacuum of the vitreous cutter (Figure 1B). After complete replacement of the aqueous humor with viscoelastic material (Figure 1C), a small puncture was made on the preserved anterior capsule with a bent needle (Figure 1D). Then capsulorhexis was performed using capsulorhexis forceps (Figure 1E).
