Canaloplasty (pronounced Kah-NAL-oh-plas-tee) is an advanced minimally invasive glaucoma treatment. As glaucoma can cause a permanent loss of vision, this procedure can provide patients with glaucoma a “peace of mind” not possible with use of glaucoma drops alone. Canaloplasty can reduce eye pressure by nearly 40%, and most glaucoma patients who have had Canaloplasty can cut their glaucoma drops in half. In some cases, Canaloplasty can even eliminate the need for Glaucoma drops. Canaloplasty can be done on its own or at the same time as cataract surgery (in which case it is called “PhacoCanaloplasty”). It is a “non-penetrating” glaucoma surgery which means it does not require creation of a hole in the eye (fistula) nor does it result in a “bleb” as required with the more traditional glaucoma surgery called trabeculectomy (“trab” for short). |
| How is Canaloplasty Performed? | Canaloplasty uses a micro-catheter to open the eye’s natural drainage system (“Schlemm’s canal”). This canal is then opened using a sterile, gel-like material (“viscoelastic”). The iTrack® micro-catheter is then removed while a suture is threaded through Schlemm’s canal. The suture is then tied down resulting in tension on the the inner wall of the canal – just as you might pull on the strings of a “hoodie” to close the hood over your face. The suture placed in the eye’s drainage canal can keep the canal stretched open for years. Once this canal is opened, the eye’s fluid can exit through a more natural process allowing the pressure in the eye to drop to a more normal level. Watch below video to see how Canaloplasty is performed. |

Yes. Canaloplasty is safe. A study compared the results of Canaloplasty vs. trabeculectomy. Although there was no significant difference in the final intraocular pressures (IOPs) between the two surgeries (meaning both surgeries were equally good at lowering IOP), two differences were noted: 1. Canaloplasty patients experienced fewer side effects and complications compared to those who had trabeculectomy; and 2. the patients who had Canaloplasty had better vision than those patients who had trabeculectomy.

Yes, Canaloplasty has proven to be effective.

If you have had either of the laser surgeries for open angle glaucoma (Argon Laser Trabeculoplasty or Selective Laser Trabeculoplasty), you may still be a candidate for Canaloplasty. It depends, however, on how much scarring there is from the laser surgery. Although your surgeon can visually inspect the area around Schelmm’s canal using a special contact lens (a technique called gonioscopy), s/he cannot tell if there has been permanent scarring of the canal itself. It may not be possible to fully catheterize the canal if there is dense scarring of the canal (called stenosis). In that case, your surgeon would not be able to stent the canal open with a suture, but would still inject a special gel (called a viscoelastic) into the partially opened canal. When the canal cannot be fully canulated and the stent is not placed, this is called viscocanalostomy. Although not as effective as canalopasty, it can still lower the IOP.
Possibly. Remember that the primary objective of any glaucoma surgery (including Canaloplasty) is to lower your IOP into a safer range and protect you from further loss of vision. A secondary goal would be to reduce (or even eliminate) the use of glaucoma drops. Studies have shown Canaloplasty to be effective at achieving both of these goals. Not only do most people who undergo Canaloplasty have lower IOPs after surgery, but on average, they are able to stop just under two medications. What does “just under two” mean? Well, some people are able to stop one drop, some two, others none and some are even able to stop all of their drops. How many you will be able to stop if you have Canaloplasty cannot be predicted, though it’s likely that you will be able to stop at least one of them if you are on multiple drops.
The amount charged for canaloplasty varies by surgeon and surgery center. If you do not have insurance, the total cost for canaloplasty can range from $4,000 to upwards of $8,000 per eye. Fortunately, Medicare and many insurances pay for Canaloplasty when surgical treatment of glaucoma is indicated. Even if you do not have insurance, however, Canaloplasty can pay for itself over time simply by saving you $1,000s per year in the cost of glaucoma drops that may no longer be necessary after this surgery.
Yes. A recent study compared one year results of Canaloplasty vs. trabeculectomy. Although there was no significant difference in the final intraocular pressures (IOPs) between the two surgeries (meaning both surgeries were equally good at lowering IOP), two differences were noted:
1. Canaloplasty patients experienced fewer side effects and complications compared to those who had trabeculectomy; and
2. The patients who had Canaloplasty had better vision than those patients who had trabeculectomy. For a more in-depth comparison, please read Canaloplasty versus Trabeculectomy.
Yes, but you may have to wait until the eye is healed from surgery. How soon you may restart use of contact lenses will be up to your surgeon. Additionally, it may be necessary to get fitted for new contact lenses after Canaloplasty as the surgery can sometimes change your refractive error. Contrast this with traditional glacuoma surgery (trabeculectomy). Because of the fragile nature of a bleb after trabeculectomy (and the risk of rupture and/or infection), once someone has had trabeculectomy surgery s/he cannot wear soft contact lenses after surgery for as long as the bleb is functioning. Hard contact lenses, however, are generally OK to wear even with trabeculectomy (though a refitting may be needed after surgery).

Benefits of Glaucoma Prevention Treatments
In glaucoma, what you don’t know can blind you. Glaucoma is an insidious eye thief which can literally rob a person blind. Because there are hardly any symptom, most glaucoma sufferers are unaware they have it. In the earlier stages of glaucoma though, a patient may only have occasional difficulty in her peripheral vision or experience a discreet form of visual field loss called a (more…) |

Glaucoma Treatment Options 101
With a patient’s sight on the line, glaucoma is a race for time. For every increase in intraocular pressure (IOP), a person with glaucoma slowly inches his way towards blindness. A glaucoma specialist therefore must overtake this process by keeping her patient’s eye pressure level normal or to minimum levels. Fortunately, a wide range of glaucoma treatment options are (more…) |

The Evolution of Glaucoma Treatment Surgery
Glaucoma is a common disease of the eye which results from the dysfunction in the eye’s drainage system – the canal of Schlemm that leads to irreversible blindness. Clogging eventually causes an increase in the eye’s pressure which damages its delicate structures, especially the nerve responsible for vision (more…) |
