Vitrectomy from the anterior approach. Vitrectomy for the anterior segment surgeon

There are three basic needs for a vitrector or vitreophage. One is for the anterior segment surgeon so that he may have a machine available when vitreous is lost during anterior segment surgery and may spare himself the hazards and potential complications of doing vitrectomy solely with cellulose sponges. The simplified vitrector which is disposable, sterile, and rapidly made ready ideally serves this need in a way which is not served by any other technique. Two, the removal of normal vitreous may be necessary in patients with vitreous contact, and any type of vitreous removing machine may be useful for this. The vitrector we have worked with is simple and satisfactory, and has the potential advantage of having blades which are always sharp and always pushed firmly against the cutting edge of the hole since they are disposable and inexpensive. An infusor as well as simple cutting tips are available. Three, vitrectomy for serious vitreous pathology can be done with the simple vitrector through the anterior segment approach if the lens is absent or will be removed, and if heavy pre-retinal and vitreous bands are not present. For the handling of diabetic retinopathy and sheets of vitreous membranes which appear organized, other equipment may be superior.
