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.
Orthopaedic Surgery6
Knee ArthroscopyA camera and small instruments are inserted through incisions the size of a buttonhole to repair cartilage, trim a torn meniscus, or remove loose fragments. Because the joint is not opened fully, recovery is far faster than traditional open knee surgery.Shoulder ArthroscopyUses a small camera and instruments through tiny incisions to repair the shoulder joint — commonly for impingement, labral tears, or damaged cartilage. Most patients go home the same day and begin physical therapy within the first week.ACL ReconstructionRebuilds the torn anterior cruciate ligament using a graft, since a fully torn ACL does not heal on its own. The surgery itself is outpatient, but returning to cutting and pivoting sports typically takes nine to twelve months of structured rehabilitation.Rotator Cuff RepairReattaches torn tendons in the shoulder to the bone. Pain relief often comes well before strength does — a sling is typical for several weeks and full recovery commonly takes four to six months, with physical therapy doing much of the work.Carpal Tunnel ReleaseCuts the ligament pressing on the median nerve at the wrist to relieve numbness, tingling, and night pain in the hand. The procedure takes about 15 minutes under local anesthesia. Night symptoms often improve immediately; grip strength returns over several weeks.Joint ReplacementDamaged joint surfaces are replaced with implants, most commonly at the knee or hip. Once exclusively a hospital procedure, selected healthy patients now have this done at surgery centers and go home the same day with a structured recovery plan.
Otolaryngology (ENT Surgery)6
Tonsillectomy / AdenoidectomyThe tonsils and sometimes the adenoids are removed for repeated infections or sleep-disordered breathing. Recovery is notably harder for adults than children, with significant throat pain for a week or more and a real emphasis on staying hydrated.Ear Tube PlacementTiny tubes are placed through the eardrum to drain fluid and ventilate the middle ear, most often for children with recurrent ear infections. The procedure takes about 10 minutes and the tubes usually fall out on their own within a year.Sinus Surgery (FESS)A camera and instruments passed through the nostrils open blocked sinus drainage pathways, with no external incisions. Considered for chronic sinusitis that has not improved with medication. Congestion often worsens briefly before it improves.SeptoplastyThe wall of cartilage and bone between the nostrils is straightened to improve airflow through a blocked side. It addresses breathing rather than external appearance, though it is sometimes combined with cosmetic reshaping.Turbinate ReductionSwollen tissue inside the nose is shrunk to improve airflow, frequently at the same time as septoplasty. Often the difference between a nose that is structurally straight and one that actually feels open.LaryngoscopyA scope examines the voice box and vocal cords, used for persistent hoarseness, difficulty swallowing, or throat pain that has not resolved. Small lesions can sometimes be biopsied or removed during the same procedure.
Plastic & Reconstructive Surgery6
Breast Augmentation / ReductionBreast size is increased by placing implants, or decreased by removing breast tissue and skin and repositioning the remaining tissue. Reduction is often performed to relieve back, neck, and shoulder pain caused by breast weight.RhinoplastySurgery that reshapes the nose by altering the bone and cartilage beneath the skin. It is performed to change appearance, to correct breathing problems caused by internal structure, or both. Swelling takes months to fully resolve.FaceliftLiposuctionFat is suctioned out from beneath the skin through small tubes called cannulas, reshaping a specific area such as the abdomen, flanks, or thighs. It targets localized deposits and is a contouring procedure rather than a method of weight loss.Wound ReconstructionRebuilds skin and underlying tissue where a wound is too large or too damaged to close directly. Surgeons move nearby tissue, or transfer skin and muscle from elsewhere on the body, to cover the defect. Often follows trauma, infection, or cancer removal.Skin GraftingHealthy skin is taken from one area of the body and transplanted to cover a wound or burn elsewhere. Both the graft site and the donor site need care, and the donor site is often the more uncomfortable of the two.
Podiatry (Foot & Ankle Surgery)6
Bunion Correction (Bunionectomy)The bony prominence at the base of the big toe is removed and the bone realigned, often with screws or plates. Recovery involves weeks in a protective shoe or boot, and swelling can persist for several months.Hammertoe CorrectionA toe permanently bent at the middle joint is straightened, sometimes with a temporary pin holding the correction. Considered when the toe rubs painfully in shoes or has developed calluses and sores.Plantar Fascia ReleaseThe tight band of tissue along the bottom of the foot is partially released to relieve stubborn heel pain. Reserved for cases that have not improved after months of stretching, orthotics, and other conservative treatment.Ankle ArthroscopyA small camera and instruments treat problems inside the ankle joint — impingement, loose fragments, or damaged cartilage — through incisions a few millimeters wide, avoiding a larger open exposure.Ingrown Toenail RemovalThe edge of a nail growing into the surrounding skin is removed under local anesthesia. When the problem keeps recurring, the nail-forming tissue at that edge is also treated so it does not grow back.Foot Fracture RepairBroken bones in the foot are realigned and stabilized with hardware so they heal in position. Because the foot bears your full weight with every step, alignment matters more here than the small bone size suggests.

Had a knee manipulation in the end of June 2025! Anesthesiologist messed up the nerves of my leg, it has been 5 months and I barely can walk! Doing lot of therapy, but not improving! I see that other people have problems with nerve block! Maybe the doctors should be more careful!!! I am not happy, I am a dancer and need my legs working properly!!!

I want to reach out to Dr. Perry Greene and the entire staff at UnaSource Surgery Center. I have never experienced a nicer group of people to take care of me. They so impressed me with their professionalism, cheerfulness, they were very comforting and they were fun. And this was all the day before Thanksgiving! I especially want to reach out to Dr. Greene whom I admire not only as my surgeon but as a man. He is a wonderful person. This was my fourth surgery performed by him (today was total right hip replacement). He also did the total left hip in 2015 and both knees together in 2018. Thank you from the bottom of my heart Dr. Greene and the entire staff at UnaSource. Also to all of you and your families I wish you a safe and Happy Thanksgiving and the same for the upcoming Holiday Season. Mike Cricelli

Our toddler recently had his surgery here. From the moment we walked through the doors, we were greeted with so much care. Everyone was so kind and thoughtful. They all really helped take the edge off and calmed our nerves. The nursing staff was so friendly and our toddler felt safe. The small touches like bringing our son a balloon with a race car on it (because they asked us what he likes) and putting a bandage on his stuffy to match his bandage really made the whole experience that much more special. Our son was so proud of himself and what could have been a super scary experience is one that we all look back on with positive memories.

Had neck and shoulder surgeries at UnaSource and was very pleased with both experiences. Loved the clean and efficiently run facilities and private recovery rooms. Definitely preferred over a hospital setting. Staff was pleasant and professional. Highly recommended.
