Introduction: One of the major concerns in laryngeal laser surgery is the risk of airway fire. The introduction ofwrapped tubes and metal tubes has reduced the fire hazards. However, these tubes are expensive and do not provide convenient access to the surgical field. There are few laboratory studies addressing the resistance of polyvinylchloride tubes against ignition in the given circum...

PURPOSE To compare intraocular lens (IOL) power calculation and refractive outcome between patients who underwent laser refractive cataract surgery with a femtosecond laser and those with conventional cataract surgery. METHODS In this prospective study, 77 eyes from 77 patients underwent laser refractive cataract surgery (laser group; Alcon LenSx femtosecond laser), and conventional cataract ...

today, lasers are widely used in biology and medicine, and the majority of healthcenters and hospitals utilize modern laser systems for diagnosis and therapy applications.researchers have introduced different medical applications for different lasers used in surgeries and other medical treatments. medical lasers can be categorized in both diagnosis and therapy branches. main difference between ...

OBJECTIVES To investigate differences in surgical time, the distance the surgical instrument travelled and number of movements required to complete manual phacoemulsification cataract surgery versus femtosecond laser cataract surgery. DESIGN Non-randomised comparative case series. SETTING Single surgery site, Moorfields Eye Hospital, UK. PARTICIPANTS 40 cataract surgeries of 40 patients. ...

SUMMARY 13 Consecutive patients who underwent endoscopic Nd - Y AG laser therapy for palliation of advanced esophageal cardnoma were treated between Oct 1989, and July 1991 , in Khatam - al -Anbia Hospital. All patients had severe dysphagia and conventional methods such as surgery , Radiotherapy and chemotherapy failed to treat them. Undoubtedly without laser therapy these patients did not see...

The introduction of a new 1318 nm wavelength Nd:YAG laser has created new possibilities in lung parenchyma surgery. The potentially curative surgical resection of pulmonary metastases in suitably selected cases had been recognized slowly. Using the new laser technology a greater number of patients can now offered salvage surgery. This paper reviews the history of surgical management of pulmonar...

Pain after laser surgery is one of the most commonly experienced patient problems. It is a pervasive part of laser treatment and a problem with which nurses and physicians are expected to deal. The nurse's most important role is preoperative patient teaching. Prior to undergoing the prescribed treatment, patients must have a realistic understanding of the laser procedure, including the expected...

The correction of presbyopia with excimer laser surgery on the cornea is the ultimate goal for this type of surgery, since all other treatments for refractive defects have been successfully developed and implemented. Surgery with excimer laser is safe and extremely effective with today’s standards; therefore, most manufacturer companies are working and devoting great research funds and efforts ...

The use of the femtosecond laser in ophthalmic surgery over the last decade has resulted in the development of innovative procedures. The ultra-short infrared laser pulses of the femtosecond laser can be applied precisely and predictably with minimal collateral tissue damage, making it an ideal tool for highly precise ophthalmic surgery. Flap creation in laser in situ keratomileusis (LASIK) is ...
