iRWD Registry™

Real-World Data Collection for Ophthalmic Office-Based Surgery

iOR Partners collects data on cases performed in iOR Surgical Suites as part of our accreditation program.  Occurrence data is collected quarterly from performed in multiple centers and different surgical techniques.  Data from over 47,000 real-world cases performed in an office-based surgery facility match or beat safety outcomes in other outpatient settings.

iOR Real-World Cases

Updated 6/30/23
Endophthalmitis 0.015% (7)
Unplanned Vitrectomy 0.198% (94)
Referred to Retina 0.080% (38)
Return to the OR 0.084% (40)
(most for removal of residual cortex)
TASS or significant iritis 0.016% (8)
Corneal Edema 0.016% (8)
Referred to Hospital 0.004% (2)
(nausea and unable to keep food and fluids down, previously undiagnosed A. Fib)

Patient Group 65 and Older

  • The overall average age of the total cases is 64.7 years
  • This group is just the patients 65 or older – 9,723 cases
  • Slight increase in unplanned vitrectomy and referral to retina
  • Overall occurrence rates similar to total cohort
Endophthalmitis 0.031%
Unplanned Vitrectomy 0.237%
Referred to Retina 0.113%
Return to the OR 0.072%
(most for removal of residual cortex)
TASS or significant iritis 0.000%
Corneal Edema 0.021%
Referred to Hospital 0.021%
(previously undiagnosed A. Fib)

Retina Only

  • Numerous retina practices are interested in OBS
  • 80% of all retinal cases are still performed in a hospital setting
  • Vitrectomy procedures have been performed safely and effectively in an accredited OBS
  • Gene therapy, sustained release intravital medication and treatments for geographic atrophy are increasing the pressure on efficiency in retinal practices
Endophthalmitis 0.0%
Retrobulbar hemorrhage 0.0%
Referred for additional Surgery 0.0%
Unplanned return to the OR for the same procedure 0.0%
Significant iritis 0.000%
Unplanned detachment 0.0%
Referred to Hospital 0.0%

Anesthesia Survey Data

  • A separate survey was done on anesthesia experience
  • 32 centers – 11,004 cases
  • OBS anesthesia types
  • Class A – oral/topical
  • Class B – IV sedation with standby anesthesia
  • Most centers started with Class B for the first few week’s cases
  • Majority of surgeons, staff and patients prefer Class A
% of cases done with Class A (oral/topical) anesthesia 95%
(average of all cases)
% of cases with anesthesia complications 0.0%
(none)
% of cases that were canceled in preop 0.063%
(all were from blood pressure that was too high)
% of cases that emergency (911) was called 0.009%
(1 case: Patient had chest pain, 911 was called, came and diagnosed as an anxiety attack and discharge to home and did fine)

Comorbidity Survey Data

71% of Patients Shown to Have Comorbidities

4,399 Patients

  • Diabetes 20.03%
  • Hypertension 50.47%
  • Heart Disease 11.28%
  • Pulmonary Disease 6.62%
  • Arthritis 15.44%
  • Allergies 18.80%
  • Bleeding Risk 5.00%

Number of Comorbidities

  • 0 (39.03%)
  • 1 (33.48%)
  • 2 (18.28%)
  • 3 (5.93%)
  • 4 (2.34%)

Antibiotic Review Results

July 2022, 40 Centers

21,031 Cases

  • 15,145 with Intracameral ABX  = 72%
  • 77% ABX only
  • 18% Anti-inflammatory/ABX
  • 5% Anti-inflammatory/ABX/NSAID

Out of the 5,886 cases that do not inject:

  • 43% use ABX GTTS
  • 8% Irrigate with BSS/ABX Solution

Office-Based Surgery Outcomes are Consistent with Other Outpatient Settings

The safety profile for services performed in office-based surgery (OBS) suites compares favorably to those performed in ambulatory surgery centers (ASCs) and confirms that ophthalmologic procedures are regularly and safely performed in the office-based setting.
