Procedures Performed

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

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.
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.
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.
HysteroscopyA slim camera passed through the cervix examines the inside of the uterus, and can remove polyps or fibroids in the same visit. No abdominal incision is involved. Cramping for a day or two afterward is normal.LaparoscopyA camera and instruments are inserted through small abdominal incisions, allowing diagnosis and treatment without a large open incision. Used for endometriosis, ovarian cysts, and pelvic pain, with recovery measured in days rather than weeks.D&C (Dilation and Curettage)The cervix is dilated and the uterine lining removed, for heavy bleeding, after a miscarriage, or to obtain tissue for diagnosis. The procedure takes 10 to 15 minutes and most people return to normal activity within a day or two.Tubal LigationThe fallopian tubes are sealed, cut, or removed to provide permanent contraception. It should be considered irreversible — reversal is not reliably successful, so it is intended for people certain they do not want future pregnancy.Endometrial AblationThe uterine lining is destroyed to reduce or stop heavy menstrual bleeding, offering an alternative to hysterectomy. It is not a contraceptive, and it is only appropriate for those who have completed childbearing.Ovarian Cyst RemovalA persistent, enlarging, or painful ovarian cyst is removed, usually laparoscopically. Surgeons generally aim to remove the cyst while preserving the ovary itself, particularly for patients who may want future pregnancy.
ColonoscopyA flexible camera examines the full length of the colon to screen for cancer and remove polyps before they become cancerous. Done under sedation, it typically takes 30 to 60 minutes. The bowel prep the day before is the part most patients find hardest.Upper Endoscopy (EGD)A thin camera passed through the mouth examines the esophagus, stomach, and the first part of the small intestine. Used to investigate persistent heartburn, difficulty swallowing, unexplained bleeding, or abdominal pain. Usually takes 15 to 30 minutes under sedation.Flexible SigmoidoscopyExamines the lower portion of the colon only, rather than its full length. Preparation is lighter than a full colonoscopy and sedation is sometimes unnecessary, but it cannot detect problems higher in the colon.Capsule EndoscopyYou swallow a vitamin-sized camera that photographs the small intestine as it passes through — a region that standard scopes cannot easily reach. There is no sedation and no recovery. The capsule passes naturally, and images are reviewed after the fact.ERCPCombines endoscopy and X-ray imaging to diagnose and treat blockages in the bile and pancreatic ducts, most often gallstones stuck in a duct. Unlike a routine endoscopy, it carries a meaningful risk of pancreatitis afterward, so it is used when treatment is likely rather than for screening alone.Hemorrhoid TreatmentShrinks or removes swollen veins in the rectum and anus using rubber band ligation, injection, or surgical removal depending on severity. Banding is quick and typically requires no anesthesia; surgical removal is more effective for advanced cases but recovery is noticeably more uncomfortable.
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.

I accompanied my friend to this medical center recently and had a very disappointing experience. While waiting alone in the reception area at the end of the day (no other patients were there), the nurse informed me that the appointment would take about 45 more minutes. During that time, I asked the front desk administrator if she could lower or mute the TV volume since I was the only one in the waiting room. To my surprise, she refused, saying it was “policy,” and even told me that if I didn’t like it, I could wait outside. This felt very inconsiderate and unprofessional. A medical facility should be a place of care and understanding, not one where staff dismiss patients’ companions in such a manner. I hope management reconsiders such policies and trains their staff to be more accommodating, especially when simple requests can improve someone’s comfort during long waits.

I’m writing this review out of deep frustration and pain over the severe medical negligence caused by the anesthesiologist during what was supposed to be a routine surgery for my wife. Due to a clear and serious error, a pretty big hole was punctured in the roof of her mouth—yet shockingly, this critical complication was never disclosed to us. We were left to discover the damage ourselves after the procedure. This outrageous wound has caused her unimaginable suffering. She has been in constant, severe pain—not just from the surgery itself, but from the puncture that made it nearly impossible for her to eat, drink, or even sleep peacefully. On top of the pain and discomfort, this kind of injury—located inside the mouth—is especially susceptible to infection, which adds yet another layer of danger and anxiety to an already terrible situation. What’s even more upsetting is the total lack of communication or any attempt by the anesthesiologist to inform us or take responsibility. It’s unethical, inexcusable, and shows a complete disregard for my wife’s well-being. We fully understand that humans can make mistakes—even in the medical field. If we had been honestly informed about what happened, we could have focused on healing and possibly even forgiven the error. But instead, we were left completely in the dark. We felt deceived and disrespected, as if the truth was hidden from us on purpose. People place their lives in the hands of medical professionals, and in this case, that trust was completely betrayed.

I went in this morning for a minor surgical procedure, and I had never had anything done under anesthesia before, so I was very nervous. I CANNOT STRESS THIS ENOUGH, the preop nurse at my arrival was so caring and sympathetic. She helped me with various things while I was extremely nervous. I wish I remembered her name, but she was a great nurse! I also think my postop nurse was amazing as well, she was very caring and informative. I would only complain about the anesthesiologist assistant being very “rushy”, when there were certain things that still needed to be done prior to me being taking back to the OR. I would definitely recommend this center for the caring nature I received otherwise!

I've been to Memorial Hermann Katy Surgery Center several times for colonoscopies, and my experience there has always been outstanding. It's a very welcoming environment, and the staff is very friendly and professional. Thank you!

I've had three procedures here and they've all been the same. The nurses and medical staff are professional and kind. The systems once out of the waiting room are efficient and well-ran. The clerical staff needs training and the pre-op process needs improving. The instructions to get in before the procedure are inaccurate. It's frustrating to arrive at 5:15am, on time, only to be locked out of the building with other waiting patients for an additional 15 minutes. I knew this was going to happen because of my previous experience and even mentioned it to the nurse who called ahead of time. She assured me that the code she gave me would work, and it did not. Once we were let inside, all 8-10 of us waited outside the locked door to the dark waiting room. This is now almost 45 minutes after the time they asked us to arrive. Nurses came by and frustratingly apologized while mentioning that they were going to find out where the receptionist was at that time. She arrived about ten minutes later, flustered and apologizing. This is a disappointing welcome for patients receiving procedures as everyone was frustrated, tired, and some were hungry from the pre-op instructions. It seems like an easy fix and would probably help their customer service reviews if they trained the receptionist on professionalism.
