Microsurgical technique for drainage of subretinal fluid with the aid of a sclerotomy retractor

In order to open the scleral incision during the whole length of microsurgical drainage of the subretinal fluid, a simple retractor was designed which allows the edges of the sclerotomy wound to spread out without the additional help of the surgeon's or assistant's hands. By elevating the instrument, traction release of subretinal fluid is also possible, even in areas far behind the equator.
