Procedures Performed

Common outpatient procedures performed at this ambulatory surgery center, based on reported specialties.

Ophthalmology (Eye Surgery)6
Cataract SurgeryThe clouded natural lens of the eye is removed and replaced with a clear artificial one. It is one of the most common outpatient procedures performed in the country, usually takes under 30 minutes per eye, and is done under light sedation with numbing drops rather than general anesthesia.LASIK / Refractive SurgeryA laser reshapes the cornea to correct nearsightedness, farsightedness, or astigmatism, reducing dependence on glasses or contacts. The procedure itself takes minutes per eye. Vision is often noticeably better within a day, though it can take several weeks to fully stabilize.Glaucoma SurgeryCreates a new drainage path for fluid inside the eye to lower internal pressure. Glaucoma damages the optic nerve silently, so the goal is preventing further vision loss rather than restoring vision already lost. Several minimally invasive options are now performed in outpatient settings.Retinal SurgeryRepairs the light-sensitive tissue at the back of the eye, most often for a detached or torn retina, or for bleeding related to diabetes. Timing matters — a detaching retina is treated urgently because delay increases the risk of permanent vision loss.Eyelid Surgery (Blepharoplasty)Removes excess skin and fat from the upper or lower eyelids. When drooping upper lids block part of the visual field, the procedure is functional rather than cosmetic and is often covered by insurance if visual field testing documents the obstruction.Corneal TransplantReplaces damaged or clouded corneal tissue with donor tissue. Modern techniques often replace only the affected layer rather than the full thickness, which shortens recovery. Vision improves gradually over months, and stitches may stay in place for a year or longer.
Interventional Pain Management6
Epidural Steroid InjectionsSteroid medication is injected near irritated spinal nerve roots to calm inflammation causing sciatica or arm pain. Often used to make physical therapy tolerable rather than as a standalone cure. There are limits on how frequently they can be repeated.Nerve Block InjectionsAnesthetic, sometimes with steroid, is injected around a specific nerve to interrupt pain signals. Used both to treat pain and to identify its source, since relief from a precisely placed block points to the nerve responsible.Radiofrequency AblationHeat generated by radio waves disables the small nerves carrying pain signals from an arthritic spinal joint. Relief commonly lasts six months to two years. Because the nerves regenerate over time, the procedure can be repeated.Spinal Cord StimulationA device delivers mild electrical pulses to the spinal cord to interrupt chronic pain signals before they reach the brain. A temporary trial period is done first, so you can judge the benefit before committing to a permanent implant.Joint InjectionsSteroid or lubricating medication is injected directly into an arthritic or inflamed joint. Image guidance is often used to confirm placement. Relief typically lasts weeks to months and can make physical therapy more productive.Trigger Point InjectionsA local anesthetic is injected into a taut, tender knot of muscle to break the spasm-and-pain cycle. The appointment takes minutes and you can usually return to normal activity the same day.

I have had procedures in several ambulatory surgery centers...nothing compares to this one. From arriving at reception to the completion of my two surgeries, the experience was superb. Every room I encountered was pristine. Everyone I came in contact with was so good at their job: prompt, professional, precise, keeping me informed as to what was going on... so friendly and kind at the same time. All in synchrony. I was put at ease immediately. No worries. Dr. Hagele, a very skilled eye surgeon, performed two cataract surgeries and the results were much more than expected. I am now able to read without glasses; and, as a bibliophile, this is very meaningful. The trees in the forest where I live are in sharper focus. Everything just looks better! Many, many thanks to Dr. Hagele, Dr. Porter for the comfort he provided, the wonderful nurses and the entire staff and surgical team at Sierra Ambulatory Surgery Center, all helping make my surgery the success it is! To have a resource of this quality in our charming rural community is awesome. This team would be a standout in any town – large or small!
