Experimental verification of subthreshold laser therapy using conventional pattern scan laser

Experimental verification of subthreshold laser therapy using conventional pattern scan laser

PURPOSE Leading-edge therapeutic laser technologies are not available at every medical facility; therefore, alternative approaches incorporating novel advances in digital and laser technology into more readily available conventional methods have generated significant research interest. Using a rabbit model, this study investigated whether the algorithm used in the Endpoint Management (EM) softw...

Comparison of subthreshold diode laser micropulse therapy versus conventional photocoagulation laser therapy as primary treatment of diabetic macular edema

PURPOSE The aim of the present study was to investigate the effect of subthreshold diode laser micropulse (SDM) in comparison with conventional laser photocoagulation in the treatment of the diabetic macular edema (DME). METHODS Sixty-eight eyes from 68 patients with clinically significant DME were divided randomly into two equal groups. In the first group, SDM photocoagulation was employed, ...

Laser Therapy of Esophageal Carcinoma

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...

Experimental Studies of Model Drug Delivery Using Superpulse CO2 Laser

Numerical and Experimental Study of Effect of Scan Velocity in Laser Forming by Temperature Gradient Mechanism

In this paper the process of laser forming has been investigated using an analytical and an experimental method for three levels scans velocity. A coupled analysis has been performed in ANSYS®. Also in order to prove the predictive methods, experiments on thin sheet metals have been done when a laser of a fair power was used. Before done, experiments were designed with full factorial chosen as ...
