Frequently Asked Questions

Office-based surgery is any surgical or invasive procedure performed by a licensed physician in a location other than a hospital or ambulatory surgery center. These procedures are typically performed in a suite located within the physician's office. 

The OBS operates at the same safety standard of care and is accredited by the same national organizations as an ASC or hospital. 

Common ophthalmic OBS procedures include basic cataract surgery, refractive cataract surgery, refractive lens exchange, ICL, various oculoplastics and other lens-based procedures. 

Other specialties that commonly perform procedures in an OBS include gastroenterology, otolargyngology, dermatology, cardiology and maxillofacial surgery.   

Of primary importance, office-based surgery provides safe and effective outcomes that are comparable to those performed in an ASC while also streamlining patient care. The largest U.S. retrospective study (Office-Based Cataract Surgery: Population Health Outcomes Study) of 21,501 cataract surgeries (13,507 patients, age 72.6 ±9.6 years) conducted in the Denver metropolitan area Kaiser office from 2011-2014 found that OBS efficacy outcomes were consistently excellent, with a safety profile expected of minimally invasive cataract procedures performed in ASCs and HOPDs. – Read White Paper on Patient Outcomes.  

In over 5000 procedures performed in iOR facilities, our safety profile is consistently as good or better as those in the Kaiser study.

 

There are two anesthesia options for ophthalmic OBS - Class A and Class B. Class A utilizes oral and local topical anesthetics and Class B utilizes monitored anesthesia requiring an anesthesia provider and RN to be present. Most OBS cases are done under Class A level anesthesia and don’t require any additional patient monitoring or staff. Patient can eat and drink immediately before surgery in Class A.

Yes, all 50 states allow for OBS. Typically, CON laws have no effect on office-based surgery.

Space needed within the office for a surgical suite runs between 750 square feet (1 OR) to 1250 square feet (2 ORs).

The LASIK suite can usually be converted to a surgical suite in most offices. 

Yes, but it may impact reimbursement.
