Video 1 Surgical procedure of limbal approach

Two limbal incisions are made by a 23-gauge trocar with a microcannula. An infusion cannula and a vitrectomy cutter are introduced through the 4 or 8 o’clock and 12 o’clock incision, respectively. A central anterior capsulotomy of 5.0 mm diameter is created using the vitrector. Lens material is then removed. A posterior capsulotomy of 4.5 mm diameter is created followed by a limited anterior vitrectomy. The microcannula at the 12 o’clock incision is then removed. This incision is then enlarged to 2.6 mm. After the ophthalmic viscosurgical device (OVD) is injected, IOL is implanted into the capsular bag. The 12 o’clock limbal incision is closed with one 10-0 nylon suture and the limbal port incision is hydrated with BSS.

Video 2 Surgical procedure of pars plana approach

An infusion cannula is inserted through a limbal port incision to maintain the anterior chamber with BSS. A vitrectomy cutter is introduced through the pars plana incision, 2.5 mm posterior to the limbus. A central anterior capsulotomy of 5.0 mm diameter is created with the vitrector. Lensectomy is then performed. A posterior capsulotomy of 4.5 mm diameter is created with the vitrectomy cutter. Limited anterior vitrectomy is performed. The microcannula of the pars plana incision is removed without suturing. Another 2.6 mm limbal incision is made at the 12 o’clock position. After the OVD is injected, IOL is implanted into the capsular bag. The limbal incision is closed with one 10-0 nylon suture and the limbal port incision is hydrated with BSS.
