Dr. Kowal is probably the busiest strabismus surgeon in Australia. If the Health Insurance Commision statistics are accurate ( and they should show all procedures that are billed through Medicare), then over the period July 1st 2019-  June 30th 2020, Dr Kowal personally performed 12% of all private strabismus surgeries in Australia and over 40% of all private strabismus surgeries in Victoria.  

These numbers are as accurate as possible and use a combination of our own data (we can vouch is accurate) and data provided on the Medicare statistics website (we assume is accurate).  The stats only refer to 'private' patients where a Medicare rebate was claimed. They do not include public, TAC or Workcover patients

Audit 2008 - 2012
Dr Kowal performed an audit of all of his surgical cases over the last 5 years.
This has included straightforward cases [high expectations of success] through to the most complex cases [these patients may have had several previous surgeries elsewhere - lower expectations of success].
Some results are:
1. 9% of patients had a 2nd surgery over an average of 30 months followup
That does not mean that 91% had a perfect outcome, but does probably mean that a very high % of patients were satisfied with the outcome.
2. 2 % of patients required a 3rd surgery within 30 months of the first surgery.

Since 1992 Dr. Kowal has been Director of the Ocular Motility Clinic at the Royal Victorian Eye and Ear Hospital.
