vitrectomiaIs an eye surgery to remove the vitreous, a clear gel that fills the eye socket, behind the lens and in contact with the internal part of the retina. Sometimes it can deteriorate, becoming and blocking the passage of light to the retina. Vitrectomy is an operation designed to remove the vitreous gel. This procedure is performed as outpatient surgery under local anesthesia with sedation. The patient is awake but does not feel pain or sees surgery that is being performed. The duration of this surgery varies depending on the pathology to be treated. Once the procedure is completed, a patch is placed over the operated eye, which will be removed by the doctor the next day. Treatment will consist of different kinds of drops in the operated eye; it may be a combination of anti-inflammatory and antibiotic or cycloplegic drops to ease discomfort and immobilize the pupil and sometimes it will also be necessary to add drops to control intraocular pressure.This surgery has allowed many patients who were hopelessly losing their vision, to maintain or recover it at very satisfactory levels. There are several retinal diseases that require vitrectomy: diabetic retinopathy, retinal detachment, eye injuries or trauma, macular disease, macular holes or macular degeneration with neovascularization, high myopia-associated pathologies, among others.
