How Long Does Canaloplasty Last? About Dr. Richardson: David Richardson, M.D. is widely recognized as one of the top #cataract and #glaucoma surgeons in the US and is among an elite group of glaucoma surgeons in the country performing the highly specialized canaloplasty procedure. Many patients have traveled from around the world to have #canaloplasty by Dr. Richardson. Moreover, Dr. Richardson is one of only a few surgeons in the greater Los Angeles area that performs Micropulse® Cyclophotocoagulation (MP3) glaucoma laser surgery. Dr. Richardson graduated Magna Cum Laude from University of Southern #California and earned his Medical Degree from Harvard Medical School. He completed his ophthalmology residency at the LAC+USC Medical Center/ Doheny Institute.

Comparing failure rates among glaucoma surgeries, however, can be challenging. Why? Because not all studies share the same definition of “failure.” ** Failure Rates for Trabeculectomy and Glaucoma Drainage Devices ** One of the definitions of failure used in the Tube versus Trabeculectomy study was an IOP greater than 17mmHg or and IOP reduction of less than 20% on two consecutive measurements. Using these failure criteria trabeculectomies fail at a rate of approximately 10% per year whereas glaucoma drainage devices fail at a rate of just over 5% per year. But many patients who undergo trabeculectomy or tube placement require an IOP reduction into the low teens. If “failure” is redefined to reflect this goal then trabeculectomies fail at a rate of approximately 15% per year whereas glaucoma drainage devices fail at a rate of approximately 10% per year. ** Failure Rates for Canaloplasty and Phacocanaloplasty ** The 3-year US study defined failure as an IOP greater than 18mmHg (with or without drops) over two consecutive visits. This is a reasonable target IOP considering that most patients who are offered canaloplasty have early to moderate glaucoma. Canaloplasty failure rates appear to be dependent upon whether cataract surgery (phacoemulsification) was done at the time of canaloplasty (this is called phacocanaloplasty). Of those who had canaloplasty alone, the rate of failure was similar to that of trabeculectomy or glaucoma drainage devices. However, of those who had cataract surgery plus canaloplasty (phacocanaloplasty) the rate of failure was less than 10% even three years out from surgery! That’s a failure rate of only 3% per year. ** Failure Rates for Viscocanalostomy ** Canaloplasty is an improvement upon an older non-penetrating surgery called viscocanalostomy. Conceived of by Dr. Robert Stegmann over two decades ago, there is now data to suggest that this surgical procedure can last for over a decade. According to a recently published study, average IOP was amazingly stable over the first ten years after surgery: 15.4 ± 3.6 mmHg at 5 years and 15.5 ± 4.4 mmHg at 10 years. By 15 years out from surgery there was a mild increase in IOP (16.8 ± 4.2 mmHg) though this was still quite an improvement from the average pre-surgery IOP of 42.6 ± 14.2 mmHg...
