Hydrus Implant

Hydrus Implant: A Procedure to Lower Eye Pressure Alongside Cataract Surgery

When a person with glaucoma is planning to have cataract surgery, a Hydrus procedure to help control the eye pressure may also be considered. Implanting a Hydrus along with cataract surgery may allow the patient to stop using one or more glaucoma eye drops. Expected recovery for combined Hydrus and cataract surgery is nearly the same as the recovery for cataract surgery alone. Studies have found the Hydrus to be very safe for those who qualify for the surgery.

How does the Hydrus work?

The Hydrus device is made of a tiny tube. The Hydrus creates a path that allows the fluid inside the eye to bypass the natural drain of the eye. Reduced drainage is one reason that high eye pressures can develop in glaucoma. The Hydrus procedure is approved to be performed only in conjunction with cataract surgery.

What are the steps of surgery?

The surgery is performed in the operating room. Your eye will be numbed with eye drops and numbing jelly. The anesthesiologist will give you medications through your IV to keep you relaxed and calm during surgery. The eye is cleaned and the face will be covered with a sterile drape. An instrument opens the eyelids. Tiny incisions for cataract surgery are made in the front of the eye. A special lens is placed on the eye to look at the eye’s natural drain, and the Hydrus is placed in the drain. The Hydrus procedure adds about 15 extra minutes to the surgery.

What will I feel during and after the surgery?
You may see bright lights during the surgery, but should not feel any pain. You will be discharged with a clear plastic shield with or without a patch over the operated eye. An adult will need to drive you home since you received sedating medications.

How often will I be seen after surgery?
You will see your doctor the first day after surgery, about a week later, and a few weeks after that. Depending on how your eye heals, additional or fewer visits may be needed.

What eye drops will I use after surgery?
Most patients will be asked to use steroid and antibiotic eye drops. How often patients take the steroid eye drops depend on the amount of the eye inflammation.

Can I stop my glaucoma drops after surgery?
Your doctor will tell you which drops to continue using and how often at each visit depending on how your eye is doing. Sometimes patients are able to reduce the number of eye drops they are taking. Even if you are taking the same glaucoma medications after the procedure, the surgery is a success if your pressure is lower. The need for eye drops long-term after this treatment varies greatly and depends on your type of glaucoma and the rate at which it is progressing.

Will my vision improve right after surgery? 

The first few days after surgery, vision may be blurry and even worse than it was before surgery. This will improve over 1-2 weeks, although it can sometimes take longer. The eye that was not operated on will not be affected, and may be depended on for vision during the recovery period (if it has vision).

What is the recovery time and what should I expect?

Depending on your job and your other eye, you should be able to return to work within a few days to a few weeks. Limitations in physical activities at work may be needed. After surgery, your eye may be sore, and it may feel like there is something in it, like an eyelash.  The drops may burn when you put them in, and your eye may water or tear a lot.  These symptoms are common but usually are mild, and improve for most people after 1-2 days.  Tylenol (acetaminophen) is a good option unless you are unable to take this medication.  If your eye has severe pain or sudden worsening pain or vision after surgery, please call our office or on call physician immediately.

Will I have restrictions after surgery?

You will be given detailed instructions after your surgery that are specific to your eye’s needs. In general, the following guidelines apply:

  • The plastic shield should be worn while sleeping for 1 or more weeks after surgery to protect the eye.
  • While outside during the day, sunglasses should be worn to protect the eye from the sun and wind.
  • For the first few weeks, avoid strenuous activities (running, lifting more than 10 pounds), bending, rubbing the eye, wearing eye makeup, and swimming.
  • There are no restrictions in reading, watching TV, using your phone, tablet device, computer, etc. but you may tire more easily during these activities.

What are the possible risks of Hydrus surgery? 

Hydrus surgery is considered a very low risk addition to cataract surgery. However, no surgery has zero risk, and possible complications are similar to those encountered in cataract surgery: infection, bleeding in the front or back part of the eye, need for additional surgical intervention, and other eye surgery complications. Sometimes there is a small amount of blood in the front of the eye after surgery, and this usually clears after the first week.

What happens if the implant does not work?

Clinical trials and our own experience have shown that glaucoma medications or an additional procedure may be needed over time in the majority of glaucoma patients including those who receive Hydrus implant. This depends on what is considered a “safe” pressure for your eye, how much your eye scars, the type of glaucoma you have, and more. After your surgery, your doctor will monitor you closely to adjust therapy if needed.
