LASIK or Laser-Assisted In Situ Keratomileusis is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses.
LASIK surgery is most commonly performed as a cure for myopia (nearsightedness), but can also be used to cure hyperopia (farsightedness) or astigmatism (corneal irregularities).
LASIK is a procedure that permanently changes the shape of the cornea using a special laser and thus focusing the light rays exactly on the retina.
The steps of the procedure are as follows:
A suction ring is placed on the eye to stabilize and check the eye pressure.
The microkeratome, a cutting instrument, is attached to the suction ring.
The blade of the microkeratome is used to cut a flap in the cornea.
The exposed inner layer of the cornea is then reshaped with an excimer laser.
The corneal flap is returned to its original position.
LASIK is an ambulatory procedure; the patient can walk into the surgery center, have the procedure and walk out again and is awake the whole time. Occasionally, the doctor may administer a mild oral sedative.
This video demonstrates the approach to a large base of tongue tumor, which was invading the ramus of the mandible. The procedure, named after Dr. Trotter, is really a median labiomandibuloglossotomy. In this case this poorly differentiated tumor was resected along with a portion of the floor of mouth. The entire area was reconstructed with a pectoralis major myocutaneous flap.
Anterior vaginal wall relaxation (cystocele) is one of the most commonly diagnosed forms of pelvic organ prolapse in women. More than 200,000 cystocele repairs are completed yearly, however to date the procedures that are completed do not provide very high cure rates and/or poor anatomic outcomes. Successful treatment of anterior vaginal wall prolapse remains one of the most challenging aspects of pelvic reconstructive surgery we face. We have developed very good procedures that provide excellent support for the posterior wall (ie rectoceles) and the apex of the vagina (ie vaginal vault prolapse) and reproduce normal anatomy. We were one of the first centers in the country to utilize grafts in rectocele repairs and have seen improved cure rates to over 90% with minimal complications. It has been known for many years that abdominal sacralcolpopexy with placement of a mesh graft at the top of the vagina for vaginal vault prolapse is the most successful procedure in the literature. We have made advancements with this procedure as well in being able to offer our patients a laparoscopic minimally invasive approach for sacralcolpopexy, with the same excellent cure rates (>92%) and with hospital stays typically less than 24 hours and reduced complications. However the anterior wall has been one of the most difficult compartments in the vagina to get good anatomic results and high cure rates with traditional repairs and at the same time not cause sexual dysfunction, pain with intercourse, voiding dysfunction (ie incontinence or urgency/frequency syndrome), or a shortened or scarred down vagina. The transobturator approach was developed as a less invasive way to place an anterior wall graft (see below) however this still involved blind needle passes and the graft did not support the apex of the vagina, therefore the search for improvements in these procedures is ongoing.
Source ABC7, 24 November 2009 An initial single-arm Phase II trial (ACT II) has reported promising preliminary data in 23 patients who received CDX-110 vaccine. Median time to disease progression was 16.6 months and estimated median overall survival was 33.1 months. This compared favorably with data for a historical control group in which median time to progression was 6.4 months and median overall survival was 15.2 months. The study was sponsored by Celldex Therapeutics Inc. of Phillipsburg, NJ
Liposuction, also known as lipoplasty (”fat modeling”), liposculpture suction lipectomy or simply lipo (”suction-assisted fat removal”) is a cosmetic surgery operation that removes fat from many different sites on the human body. Areas affected can range from the abdomen, thighs, buttocks, to the neck, backs of the arms and elsewhere.

Several factors limit the amount of fat that can be safely removed in one session. Ultimately, the operating physician and the patient make the decision. There are negative aspects to removing too much fat. Unusual “lumpiness” and/or “dents” in the skin can be seen in those patients “over-suctioned”. The more fat removed, the higher the surgical risk.
While reports of people removing 50 pounds (22.7 kg) of fat has been claimed, the contouring possible with liposuction may cause the appearance of weight loss to be greater than the actual amount of fat removed. The procedure may be performed under general or local (”tumescent”) anesthesia. The safety of the technique relates not only to the amount of tissue removed, but to the choice of anesthetic and the patient’s overall health. It is ideal for the patient to be as fit as possible before the procedure and not to have smoked for several months.
