Abstract

We retrospectively evaluated the VITAC (vitreous-tissue aspiration cutter), a portable vitrectomy system with an end-cutting vitrectomy probe with a self-sharpening oscillating blade and a monoblock design, in 110 vitrectomy procedures, 34 performed at the University of California Davis Medical Center and 76 performed at the Eye and ENT Hospital in Shanghai, China. The indications for vitrectomy included penetrating injuries (22 eyes), intraocular foreign bodies (28 eyes), vitreous hemorrhages (18 eyes), cataracts (17 eyes), endophthalmitis (seven eyes), pupillary-block glaucoma (five eyes), aphakic penetrating keratoplasty (three eyes), pupillary membranes 9two eyes), massive preretinal proliferation (one eye), and cystoid macular edema (one eye). Vitrectomy resulted in visual improvement in 19 of 34 eyes in the California series (56%) and in 60 of the 76 eyes in the Shanghai series (79%). This difference was attributable to the higher percentages of cases involving the posterior segment and vitreous hemorrhage in the California series. When results from both institutions were combined, surgery with the VITAC produced visual improvement in 79 of 110 cases (72%), comparable to the results obtained with other vitrectomy systems.
