          Diamond dust particles were identified within patients’ eyes both during vitrectomy procedures using diamond-dusted membrane scrapers and in postoperative clinical examinations. The particles had no impact on the patients’ vision and caused no apparent sequelae. Scanning electron microscopy analysis showed the average particle size to be 23.4 μm and an unequal surface area for particle adhesion onto the soft tip. It was determined that diamond dust particles can dislodge from the silicone tip of the Tano diamond-dusted membrane scrapers during the insertion into valve trocars throughout vitrectomy operations and deposit on the retinal surface or within macular holes. Ophthalmologists should be aware of residual diamond particles during procedures and consider diamond dust retinopathy in the differential diagnosis of crystalline retinopathies. Understanding the appearance of residual particles on the retina allows for future studies revealing the long-term impact on patient’s visual performance.

            Diamond-dusted microspatula tips for vitreoretinal surgery.

            We have developed a microsurgical spatula set consisting of four different tips and a universal handle. The set offers a range of tip angulation of 30 degrees, 45 degrees, 60 degrees, and 80 degrees. The bottom surfaces of the spatula tips are covered with fine diamond dust. The 30 degrees tip has a blunt and tapered end. All tips can be introduced through a conventional 20-gauge sclerotomy in a pars plana vitrectomy. The tips fit on a universal handle. The set has been used as a complement to vitreous forceps in dissecting and removing preretinal membrane.
