Retinal detachment surgery usually takes about one to several hours, depending on the repair needed. Some operations take around an hour, while more complex cases can take longer. The time in the hospital or surgery center is longer than the operation itself because staff must prepare you, give anesthesia, and monitor you afterward. Your retinal surgeon can estimate the likely duration for your specific procedure.
What Is the Usual Duration of Retinal Detachment Surgery?
As a general guide, retinal detachment surgery may take around one to two hours, although some procedures finish sooner and others take several hours. According to the University of Pittsburgh Department of Ophthalmology, the operation can last anywhere from an hour to several hours, depending on the location and extent of the detachment and the person's overall health.
There is no single time that applies to every patient. The operation may involve repairing one retinal tear or treating several tears and a larger detached area. The surgeon may also need to use more than one technique to help the retina return to its proper position.
What Factors Affect How Long the Operation Takes?
Several factors influence the length of retinal detachment surgery. The most important is the type and complexity of the repair required. The National Eye Institute explains that the choice of surgery depends on how much of the retina has detached and where the detachment is located. Some patients need a combination of procedures rather than just one technique.
Other factors include the number and position of retinal tears, whether fluid needs to be drained from beneath the retina, and whether additional treatment is needed during the operation. The type of anesthesia and a person's general health can also influence the overall surgical process. Your ophthalmologist can discuss which of these factors apply to the planned procedure.
How Long Does Each Type of Retinal Detachment Surgery Take?
Retinal detachment can be repaired using different techniques. The procedures differ in how they work and where they are performed, so their duration can vary.
Vitrectomy
A vitrectomy is an operation in which the surgeon removes the gel-like fluid inside the eye, called the vitreous. The surgeon can then repair retinal tears and may place a bubble of gas, air, or silicone oil inside the eye to help hold the retina in position. Depending on the extent of the detachment and the additional steps required, a vitrectomy may take an hour or several hours.
According to Mayo Clinic, vitrectomy may be combined with scleral buckle surgery. When several repair steps are needed, the procedure may take longer than a less complex operation.
Scleral Buckle Surgery
In scleral buckle surgery, the surgeon attaches a small silicone band to the outside of the eye. This gently indents the eye wall, helping the detached retina move closer to the underlying tissue. The surgeon may also seal retinal tears with laser or freezing treatment and, in some cases, drain fluid beneath the retina.
The operation often takes around an hour, although additional repair work can increase the duration. The exact time depends on the surgical plan and the findings during the procedure.
Pneumatic Retinopexy
Pneumatic retinopexy involves injecting a small bubble of gas into the eye. The bubble helps press the detached area of the retina back against the eye wall while the surgeon seals the retinal tear with laser or freezing treatment. This procedure can often be performed in an eye doctor's office rather than an operating room.
It is generally a less involved procedure than a vitrectomy or scleral buckle operation, but it is suitable only for certain types of retinal detachment. Your retinal specialist will determine whether it is an appropriate option and explain how long the treatment is expected to take.
How Much Time Should You Allow for the Hospital Visit?
The total visit usually takes longer than the operation itself. Before surgery, the team may review your medical history, check your vital signs, examine your eye, administer eye drops, and prepare you for anesthesia. These steps take time even when the operation is relatively short.
After surgery, you will usually spend time in a recovery area while staff monitor you as the effects of anesthesia wear off. They will check your eye and make sure you are well enough to leave. You may receive instructions about eye drops, protecting the operated eye, and positioning your head if a gas bubble has been used.
The NHS notes that patients do not normally need to stay overnight after retinal detachment surgery. Many procedures are completed as day cases, but an overnight stay may be needed in some circumstances. Confirm your expected arrival time and discharge arrangements with your surgical team rather than planning around the estimated operating time alone.
Will You Be Awake During Retinal Detachment Surgery?
That depends on the type of procedure, your health, and the anesthetic plan. Many retinal detachment operations use local anesthesia, which numbs the eye and surrounding area while you remain awake. Some patients receive sedation to help them relax, while others need general anesthesia and are asleep throughout the operation.
Your surgical team will explain which approach is planned and what you should expect. If you are awake, you may notice bright lights or movement, but the anesthetic is intended to prevent pain during the procedure. Tell your team about your medical conditions, medicines, allergies, or concerns about anesthesia before surgery.
Does the Length of Surgery Affect Recovery Time?
The time spent in surgery is different from the time needed for your eye to heal. Even after a successful operation, vision may remain blurry for several weeks and can take months to improve. Recovery depends on factors such as the extent of the retinal detachment, the type of repair, and how the eye heals.
If a gas bubble is placed in the eye, you may need to maintain a particular head position for a period specified by your surgeon. You may also need to avoid flying or traveling to high altitudes while the bubble remains in the eye. Follow your own postoperative instructions, attend follow-up appointments, and ask when it is safe to return to work, exercise, driving, and other usual activities.
How Can You Prepare for Surgery Day?
Planning ahead can make the hospital visit easier, even if the length of surgery changes. Follow the instructions provided by your surgical team, especially those about eating, drinking, and taking your usual medicines. Do not stop prescribed medication unless your clinician specifically instructs you to do so.
Arrange for someone to take you home, since you should not drive immediately after eye surgery or anesthesia. Allow enough time for preparation and recovery, and ask the hospital whether you should expect to return home the same day or might need to stay overnight.
When Should You Seek Urgent Eye Care?
Retinal detachment is an eye emergency because delayed treatment can threaten vision. If you experience a sudden increase in floaters, flashes of light, a dark curtain or shadow across your vision, or sudden blurred vision, seek urgent eye assessment. The NHS advises urgent medical help for these symptoms. Do not delay assessment while trying to estimate how long surgery might take.
If retinal detachment has already been identified, ask your retinal specialist how soon your procedure should take place. The timing of treatment is a separate question from the length of the operation, and your care team can explain the appropriate plan for your situation.
