What is a vitrectomy probe?
The ULTRAVIT® Vitrectomy Probe is indicated for vitreous cutting and aspiration, membrane cutting and aspiration, dissection of tissue and lens removal. The valved entry system is indicated for scleral incision, canulae for posterior instrument access and venting of valved cannulae.
What instruments are used in a vitrectomy?
- Colibri Forceps (with 0.12 Teeth)
- Standard “Smooth” Dressing Straight Forceps.
- Storz Tying Forceps (“Heavy Ties”)
- Curved Tying Forceps.
- Nugent Utility Forceps with Smooth Jaw.
- McPherson Iris Forceps Tying Strait (“Strait Ties”)
- McPherson Iris Forceps Tying Angled (“Angled Ties”)
What is a 25 gauge vitrectomy?
25-gauge transconjunctival sutureless vitrectomy is a major advance in the field of minimally invasive vitreoretinal surgery. It allows surgeons to perform minimally invasive surgical procedures, resulting in better outcomes and easier patient recuperation.
What is small gauge vitrectomy?
Small gauge vitrectomy surgery, which sometimes is referred to as minimally invasive vitreous surgery or MIVS, is an operation performed by a retinal specialist to treat a multitude of retinal conditions including retinal detachments, macular holes, vitreous hemorrhages, epiretinal membranes and more.
Does vitreous gel grow back?
The vitreous body cannot regenerate, so the vitreous cavity must be filled with suitable vitreous substitutes that keep the retina in place and prevent insertion of prosthesis after enucleation of the eye.
Does vitrectomy remove all floaters?
An ophthalmologist removes the vitreous through a small incision (vitrectomy) and replaces it with a solution to help your eye maintain its shape. Surgery may not remove all the floaters, and new floaters can develop after surgery. Risks of a vitrectomy include bleeding and retinal tears.
What is a 3 port vitrectomy?
In 1974, Conor O’Malley and Ralph Heintz developed the modern-day three-port vitrectomy system – with dedicated ports for vitreous removal using the vitrectomy cutter, infusion of fluid to maintain IOP, and illumination of the posterior segment – using 20-gauge instruments.
What is a vitreous cutter?
Since the 1970s, vitreous cutters have been modified to achieve high performance surgeries while maintaining safety. Numerous components such as the cutter size, cutting speed, port geometry, blade design and duty cycle, can alter the surgical efficiency and impact the postoperative results.
What is vitrectomy done for?
A vitrectomy is a type of eye surgery to treat various problems with the retina and vitreous. During the surgery, your surgeon removes the vitreous and replaces it with another solution. The vitreous is a gel-like substance that fills the middle portion of your eye.
Does macular pucker surgery require face down recovery?
CONCLUSION. The results of our case series show that, using the surgical techniques described here, facedown positioning is not necessary after surgery for idiopathic macular hole closure.
What fills the eye after vitrectomy?
The eye is left filled with sterile saline (salt water) or with a vitreous substitute such as a gas bubble or silicone oil. When a vitreous substitute is used, a period of post-operative positioning (typically face-down) by the patient helps the retina heal.
