Inferior Removal of Dislocated Polymethyl Methacrylate Intraocular Lens and Scleral Refixation in Glaucomatous Eyes
Video 1: The inserted IOL was fixed in the sclera using Yamane’s method. The details of the proposed methodology are presented.
Effect of Different Preoperative Intraocular Pressures on the Prognosis of Traumatic Cyclodialysis Cleft Associated with Lens Subluxation
Peer-reviewed videos describing the effect of different preoperative pressures on the prognosis of traumatic cyclodialysis cleft associated with lens subluxation.
Video 1: The capsular bag is implanted to support the zonules, and a foldable intraocular lens is inserted into the capsule. After zonular dialysis, a 13-mm Morcher Type 2 L CTR, MCTR, with two perforations is pre-placed into the ciliary sulcus with 10-0 polypropylene, and then the end of the Prolene suture is placed on the sclera and it is tied 1 mm behind the edge of the surgical site.
Video 2: The location of a small hole is pushed to the maximum height of the fissure, which causes the detached ciliary body to be reconnected to the scleral spur via direct mechanical packaging. Furthermore, the cyclodialysis cleft closure was confirmed by gonioscopy at the end of surgery.

Video showing excerpts of the surgical technique implemented in the study The Video presenting Visco-Trab operation combined with clear cornea temporal phacoemulsification and in-the-bag foldable intraocular lens implantation in a patient with advanced primary open-angle glaucoma and posterior subcapsular cataract.Steps of combined Visco-Trab operation include fornix-based conjunctival flap and subconjunctival Mitomycin C 0.3 mg for 3 min followed by through wash with BSS. A 4x4mm lamellar scleral flap (1/3-1/2 of thickness) extending 1mm in clear cornea. Deep scleral flap dissection 0.5 mm inside edge, leaving thin scleral over choroid. Exposure & deroofing of Schlemm’s canal. When the glaucoma procedure is combined with phacoemulsification, once the canal is deroofed, the surgeon moves to the temporal side to do the cataract operation through a clear-cornea incision. At the end of the phaco procedure, the AC is reformed and the corneal wound is secured by one 10/0 Nylon suture and the surgeon reverts back to upper position to complete the filtering operation. Excision of deep scleral flap creating a scleral lake. Dilation of SC on either side with sodium hyaluronate. Penetrating trabeculectomy (1×2 mm) and wide peripheral iridectomy were done followed by water tight closure of lamellar scleral flap and conjunctival flap.

Video 1 : Bioniko eye model for simulation of angle surgery. The TRAB™360 surgical technique and GATT are performed in this model
Video 2 : TRAB™360 surgical technique . The instrument is used to pierce the trabecular meshwork; the inner filament is threaded 180° in Schlemm’s canal and then unroofed. The same procedure is performed for the remaining 180°.
Video 3 : Gonioscopic-assisted transluminal trabeculotomy (GATT) with the iTrack™ catheter . The catheter is grasped and directed to the opening in Schlemm’s canal. The catheter is then fed into the canal and then Schlemm’s canal is unroofed.

Video 2 : Method of inserting a tube into the anterior chamber using a blunt-tipped cannula. The tip of the cannula is firmly engaged onto the cut bevel of the tube and gently inserted through the scleral tunnel taking the tube with it.

Video 3 : A long tunnel in the patient’s native sclera created using a small mini-crescent blade (1.25 mm in width) that can be used to tunnel in the sclera up to about 2 mm posterior to the limbus, then completing the entry into the eye with a 25-gauge needle. (Courtesy of James D. Brandt, MD)
Video 4 : Insertion of the tube of a Baerveldt glaucoma drainage device in an eye with aniridia . The lens is slightly displaced to the nasal side, and insertion of the tube at a tangent avoids contact with the lens. The anterior chamber infusion maintains the anterior chamber and constant intraocular pressure throughout the procedure. (Courtesy of Cecilia Fenerty, MD, FRCOphth and Tanya Karaconji, MD, FRANZCO)
