A mechanical vitrectomy with removal of the preretinal cellular membrane, commonly known as a macular pucker, is a surgical procedure performed through a pars plana approach. The vitreous, which is a clear, gel-like substance filling the center of the eye, is removed to facilitate the treatment of the macular pucker, also referred to as an epiretinal membrane or preretinal membrane. A macular pucker occurs when the vitreous detaches from the retina, leading to microscopic damage that results in the formation of scar tissue at the site of detachment. This condition can significantly impair vision, causing symptoms such as blurred or distorted sight. During the procedure, three small incisions are made in the eye at the pars plana, which is situated in front of the ciliary body and behind the retina. Through these incisions, a light pipe, an infusion port, and a vitrectomy device are inserted. The light pipe illuminates the interior of the eye, while the vitrectomy device, which operates with microscopic oscillating cutting motions, is used to remove the vitreous gel in a controlled manner. As the vitreous gel is extracted, it is replaced with fluid via the infusion port to maintain intraocular pressure. The central vitreous is thoroughly removed, allowing access to the vitreous base. With the aid of high magnification, the edge of the cellular membrane is carefully elevated, and microforceps are utilized to further lift and remove the preretinal cellular membrane. Finally, the retina is examined for any signs of tearing before the surgical instruments are withdrawn from the eye.
