Abstract

BACKGROUND The B-Laser™ atherectomy system (Eximo Medical, Israel) is a 355 nm solid-state Nd:YAG short pulse laser for de-novo and restenotic infrainguinal PAD with enhanced affinity for atheroma and calcified plaque. METHODS The study was a prospective, single-arm, multi-center, international, open-label study assessing the B-Laser™ in symptomatic (Rutherford 2 to 4) infrainguinal peripheral artery disease. Primary core lab efficacy was mean reduction in diameter stenosis >20% by the B-Laser™ catheter alone. Cardiovascular death, major amputation, target lesion revascularization, WIQ, ABI and Rutherford class were obtained at baseline and out to 6 months. Duplex ultrasound patency (PSVR

Abstract

Purpose: To report the first case of Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser use to recanalize a CyPass occluded with a clot in the early postoperative follow-up. Observations: A 66 year-old woman with primary open angle glaucoma and cataract received combined cataract surgery plus CyPass in the right eye. Surgery was uneventful, however, there was a small amount of hyphema related to bleeding around the site of Cypass insertion. Intraocular pressure (IOP) was between 6 and 7 mmHg in the first week on no glaucoma medications. At the second postoperative week, IOP jumped to 30 mmHg and a clot was observed obstructing the CyPass lumen. We disrupted the clot with a single shot from a Nd:YAG laser. Twenty minutes after the laser, the IOP was 8 mmHg. CyPass was recanalized without complications. IOP was 11 mmHg at 1 month postoperatively with timolol 0.5% twice a day. Conclusions and importance: It is important to perform gonioscopy to evaluate for CyPass obstruction in cases of IOP spike. Nd:YAG laser may be a useful approach to recanalize the CyPass in the early postoperative follow-up. Keywords: Glaucoma, Lasers solid-state, Cataract extraction

Abstract

Purpose: To report two cases of neurotrophic keratitis (NK) after micropulse transscleral cyclophotocoagulation (MP-TCP). Observations: Two patients with predisposing factors for decreased corneal sensation developed NK 1 month after MP-TCP. Both patients did not heal with initial treatment with topical antibiotic and preservative free artificial tears. One patient required use of a bandage contact lens and the other patient required tarsorrhaphy. Both eyes experienced recurrence of NK. Conclusions and importance: NK can be triggered after MP-TCP in patients with underlying predisposing factors for decreased corneal sensation. This uncommon but vision-threatening complication should be discussed preoperatively with high-risk patients as a possible adverse event after MP-TCP and followed closely postoperatively.
