This video shows an iLASIK procdure using the IntraLase iFS femtosecond laaer and the Visx STAAR S4 excimer laser to perform a wavefront-guided LASIK after implantation of a Tecnis diffractive mutifocal IOL.

Flattened sclerotomies are an essential step in ensuring postoperative wound stability in transconjunctival sutureless vitrectomy. However, in complex cases involving complete vitrectomy with shaving of the vitreous base, laser application and peeling of surface membranes, conventional angled incisions often leak at the end of the procedure. Here, we present a novel curved and twisted (screw-like=“screwcut“) self-sealing incision technique using a 23-gauge one-step microcannula array with sharp solid trocar blades. Based on a simple kitchen experiment, we demonstrate that this approach provides excellent wound closure and potentially minimizes the risk of wound leak in sutureless vitreoretinal surgery.

A combined hamartoma of the optic disc and the RPE may show as a submacular CNV or/ and an epimacular gliosis. In this example the visual acuity is 20/200 and stable but metamorphopsia is a constant complaint. The surgical approach aims to release epiretinal traction via ILM peeling and thereby improve the metamorphopsia. No epiretinal tissue is found, since the ILM stains homogenously. A fibrous tuft is peeled from the optic disc. Since in angiography there is no leakage from the subretinal RPE and no CNV, no subretinal membrane extraction is attempted. In concluding the retinal periphery is inspected an a fresh horseshoe tear is detected at 3 hours, not associated with the sclerotomy and addressed by cryopexy.

This video shows an intraocular femtosecond laser (Alcon LenSx Lasers, Inc, Ft. Worth, TX, USA) used to perform laser refractive lens surgery. The laser uses build-in optical coherence tomography (OCT) to image the cornea, lens capsule and lens. Nucleus liquefaction, capsulorhexis and corneal incisions are then positioned on the screen, and the laser performs lens liquefaction followed by capsulorhexis and corneal incisions. Irrigation/aspiration only is used to remove the liquefied lens nucleus, and an intraocular lens is implanted. Laser refractive lens surgery provides a far more accurate size and position of the capsulorhexis than the manual technique and enables the surgeon to combine the lens surgery with intracorneal refractive incision to correct astigmatism.

The overly hard fluid jet of liquid perfluorocarbon directed towards the posterior pole of the eye near the retinal surface perforates the fovea. Most of the subretinal fluid escapes spontaneously via a pre-existing retinotomy. Remnants of submacular PFCL are being evacuated by the pressure of a preretinal PFCL bubble and subretinal aspiration. The procedure is completed by submacular transplantation of autologous pigment epithelium and choroid. The iatrogenic macular hole is addressed by ILM peeling.

This BBG is not heavier than water, thus no admixture of glucose, not cooled down, and no admixture of heavy water yet. It does stain the ILM sufficiently but somewhat less intense than the heavier than water ICG. The intensity of the staining is sufficient to identify and peel the ILM.

Occasionally and usually unexpected the instrument (light pipe, cutter, forceps) introduced through the sclerotomy pushes forward condensed vitreous that is connected to the peripheral retina. The stress from the induced traction is usually sufficient to create a more or less large dialysis. Being aware of the risk, peripheral fundus inspection with indentation and eventual cryopexy or endolaser is the treatment of choice, not necessarily combined with a tamponade in otherwise attached retina.

Especially heavy silicone oil has the peculiarity to be retained and entangled into the vitreous base. Thus after aspiration of the core of heavy oil it is strongly recommended to inspect the vitreous base with indentation. Since the oil bubbles are entrapped in the vitreous it requires active suction and cutting with a vitrectomy probe.
