Laser history in Gynecology and obstetrics

Laser history in Gynecology and obstetrics
During the last decade, the use of laser technology has become more common in operative gynaecology in Norway. The first modality to be introduced was the carbondioxide, CO2-laser, used together with the colposcope for the treatment of cervical intraepithelial dysplasia and condylomata. The same laser has also been employed through laparoscopic technique, with the aid of modern microvideofacilities. Finally, using the hysteroscopic technique, the Neodymium-Yttrium-Aluminium-Garnet, the Nd-YAG-laser and similar diode laser, has been introduced for treating intrauterine conditions. The use of laser in operative gynaecology makes it necessary to change the attitude towards indications for operation. The possibilities are challenging, and the effect on the length of postoperative convalescence is especially rewarding. The introduction of lasers in gynaecology could have far-reaching consequences for efficient use of hospital resources.

Role of Laser in the treatment of spider veins

Role of Laser in the treatment of spider veins


What is the role of Laser in the treatment of spider veins?
The best and gold standard treatment for spider veins is laser. Laser vein removal is an easy, fast, and effective way to treat superficial veins Laser therapy has been used in the medicine for more than 30 years. Advances in technology have helped developed many different lasers. The laser uses a focused beam of light. In the treatment of veins, the wavelength of light is targeted to the pigment in the blood. The laser heats up the small vein and destroys it. The laser beam is focused and does not damage the nearby skin tissue. Over a period of four to six weeks, the vein is reabsorbed by the body and disappears.

Infrared Laser cyclophotocoagulation in treatment of refractory glaucoma




Laser cyclophotocoagulation in treatment of refractory glaucoma


Long - term effect of transscleral diode laser cyclophotocoagulation in treatment of refractory glaucoma [Ophthalmology]


Keywords:diode laser,cyclophotocoagulation,refractory glaucoma


Abstract


AIM: To evaluate the long-term efficiency of diode laser transscleral cyclophotocoagulation (DL Tscpc) for refractory glaucoma.
METHODS: Retrospective analysis was made in 431 eyes with refractory glaucoma treated by DL Tscpc with lower energy power (1.5-2.5W) and more laser spots (26-34). Intraocular pressure (IOP), visualacuity, ocular symptoms and complications were observed after DLTscpc. Patients were followed up over 36 months.


RESULTS: Mean pre-operative IOP was (56.2±12.7)mmHg which was significantly different from the final follow-up mean IOP (17.3±8.8)mmHg. (P < 0.05). The success rate was 94.4% (68/72). Postoperative visual acuity kept no change in 399 eyes; elevated in 30 eyes and decreased in two eyes. The pain sense disappeared or remarkably relieved. The main complications included mild uveitis and hyphemae. Atrophy of eyeball occurred in two eyes.


CONCLUSION: It is concluded that DL TScpc is a simple, safe and effective therapy for eyes with refractory glaucoma through long-term observation.

Laser Acupuncture, Acupuncture without needle

Laser Acupuncture (Needleless Acupuncture)

Laser Acupuncture (Needleless Acupuncture)

Laser Acupuncture relies upon similar dosage principles as needling, and knowledge of acupuncture theory and practice is required. There are two approaches; first the Precise Approach; and second the General Approach.
1. The Precise Approach uses the laser with great finesse to effect stimulation of the precise acupuncture points. Some believe that lower dosages will “tonify” the acupuncture points, while higher dosages will “sedate” the acupuncture points.
2. The General Approach uses the laser to stimulate the acupuncture points and the surrounding area of the acupuncture point.
Active acupuncture points are typically painful upon palpation. The application of laser therapy has proven to be effective at “releasing” the acupuncture point, and reducing pain

Importance of Wearing Safety Goggles

Importance of Wearing Safety Goggles

Laser beam focused by the lens on the retina or fovea
An incident laser beam striking directly inline with the lens is very
dangerous. The beam is magnified over 100,000 times by the lens of the eye. The more divergence of the beam the less light strikes the eye.
The more the mean is focused or collimated the greater the fluence of the beam and potential for injury.

Safety Goggles
Not all Safety Goggles are the same. The protective eyewear that came with your laser is manufactured specifically for the wavelengths emitted by the laser.

Latest Femtosecond laser for LASIK

Latest Femtosecond laser for LASIK
Femtosecond (fs) lasers for LASIK flap creation have increased their market share from 0 percent in 2001 to over 55 percent in 2010. Now, in cataract surgery a similar revolution may take place. What makes this technology so special and which new areas of surgery will furthermore be entered in the future? 

femtosecond lasers are efficacious devices for creating LASIK flaps, with accompanying good visual results. Overall, femtosecond lasers were found to be as good as or better than mechanical microkeratomes for creating LASIK flaps. There are unique complications that can occur with femtosecond lasers.
