Vitreoretinal dissection instruments.

We developed and evaluated clinically a series of three vitreoretinal dissection instruments with a constant-diameter shaft and various tip designs including a 90-degree hooked tip, a 130-degree hooked tip, and a blunt-tip right-angle spatula. The instruments, manufactured from a titanium alloy, are lightweight and glare resistant. We have used these instruments interchangeably with other vitreous surgery instruments introduced through a 20-gauge sclerotomy. They facilitate delicate manipulations associated with separation of epiretinal membranes from the inner retinal surface.
