Vitrectomy Surgery for Retinal and Vitreous Conditions in Sydney

Vitrectomy surgery is a specialised eye procedure used to treat disorders affecting the retina and vitreous. It is commonly recommended when vision is threatened by bleeding, scar tissue or retinal damage that cannot be managed with less invasive treatments. At Sydney Retina Clinic & Day Surgery, vitrectomy procedures are performed by experienced ophthalmologists and vitreoretinal surgeons in a dedicated on-site day surgery facility. This ensures timely, precise care with close post-operative monitoring.

Vitrectomy plays an important role in preserving eye health and, in many cases, improving or stabilising vision.

What Is Vitrectomy Surgery and How Does It Work?

Vitrectomy is a microsurgical procedure that involves removing the vitreous gel from the centre of the eye. The vitreous is replaced with a sterile saline solution that closely resembles the natural fluid produced within the eye. Removing the vitreous allows the surgeon to access the retina and treat underlying problems more effectively. Vitrectomy may be performed on its own or combined with other eye surgeries, such as retinal detachment repair or cataract surgery.

This technique allows delicate retinal work to be performed with precision.

When Vitrectomy Surgery Is Required

Vitrectomy surgery is required for a range of retinal and vitreous conditions that interfere with vision or threaten eye health. It may be used to remove scar tissue growing on the vitreous or retina, which can pull on the retina and cause detachment. Vitrectomy is also necessary when bleeding inside the eye blocks light from reaching the retina. These conditions often cannot be resolved without surgical intervention.

Early treatment can help prevent further damage.

Eye Conditions Treated With Vitrectomy Surgery

Vitrectomy is commonly performed for diabetic traction retinopathy, where bleeding and scar tissue develop in diabetic eyes. It is also used to treat proliferative vitreoretinopathy, a condition involving scar tissue formation after severe retinal detachment. Other indications include epiretinal membranes, macular hole surgery and retinal detachment repair. Trauma, intraocular foreign bodies and complications following cataract surgery may also require vitrectomy.

Each procedure is tailored to the specific condition and severity.

How Vitrectomy Surgery Is Performed

Vitrectomy surgery is performed in our on-site day surgery unit, usually under local anaesthesia. During the procedure, fine 23-gauge microsurgical instruments are inserted into the eye through three very small incisions in the sclera, the white part of the eye. The vitreous gel is carefully removed and replaced with a specialised fluid to maintain eye shape and pressure. Additional instruments may be used to remove scar tissue or repair the retina.

Laser treatment can also be performed during surgery if required.

Advanced Sutureless Vitrectomy Techniques

Modern vitrectomy surgery is typically sutureless, using smaller-gauge instruments and a self-retaining cannula system. This allows the tiny incision sites to self-seal at the end of surgery. Sutureless techniques reduce inflammation and discomfort after surgery. They also support quicker healing and shorter operating times.

This approach improves patient comfort and recovery.

Recovery and What to Expect After Vitrectomy Surgery

Significant pain after vitrectomy surgery is uncommon, although mild discomfort or a scratchy sensation may be experienced. This usually settles quickly with prescribed medication. Patients are discharged with an eye pad, which is removed at a follow-up appointment the next day. Eye drops are required after surgery to reduce inflammation and prevent infection.

Clear postoperative instructions are provided to support recovery.

Gas Bubble Use and Post-Operative Precautions

In some cases, a gas bubble is placed inside the eye at the end of vitrectomy surgery to support retinal healing. If a gas bubble is present, vision will be reduced until it is absorbed naturally by the body. Air travel and high-altitude activities must be avoided during this time, as altitude changes can cause a dangerous rise in eye pressure. Your surgeon will advise when it is safe to resume normal activities.

Following these precautions is essential for safety.

Risks and Safety of Vitrectomy Surgery

All surgical procedures carry some level of risk, and vitrectomy is no exception. Potential risks include infection, bleeding, retinal detachment and increased eye pressure. Cataract formation may also occur more rapidly following vitrectomy. In many cases, however, the risks of surgery are outweighed by the benefits of preserving vision or preventing further eye damage.

Your ophthalmologist will discuss risks and benefits in detail before surgery.

Visual Outcomes After Vitrectomy Surgery

Visual improvement after vitrectomy depends on the severity and duration of the eye condition before surgery. If permanent retinal damage has already occurred, visual improvement may be limited. In some cases, vitrectomy is performed to stabilise the eye and prevent further vision loss rather than to improve sight. Your ophthalmologist will explain realistic expectations based on your individual condition.

Every patient’s outcome is unique.
