Photodisruption | definition of photodisruption by Medical dictionary In short, excimer laser emits far UV light wavelength that can disrupt chemical bonds in the . Cases were treated using a diode laser delivery system through either an operating microscope adapter (OMA) or a laser indirect ophthalmoscope (LIO) with a 20D lens. Excimer photoablation was performed in a 6.0-6.5 mm optical zone; 4) outcome: dry eye parameters. PPT - Introduction to Minor Surgical Procedures PowerPoint Presentation ... d. Photodisruption: primary type of laser tissue interaction used in LASIK surgery. . Long-term results of small-incision lenticule extraction in high myopia (15) Femtosecond lasers work by cutting tissues with a process of photodisruption, unlike argon (photocoagulation) and excimer (photoablation) lasers. 40 40. Lasers (surgery) - EyeWiki Most ophthalmologists are familiar with the linear absorption of light energy, which leads to the process known as photoablation that is produced by excimer lasers. • The output is highly collimated laser beam about 1 mm to less than 1cm. Tissue is heated until destroyed 2. . LASERs in Ophthalmology: A Concise Guide for the Postgraduates Commonly used C02 Absorbed by water of cells Visible vapor (vaporization) Heat Cell disintegration Incision Cauterization . All cases presented as unilateral areas of raised iris hyperpigmentation, ranging in size from 2× 3 mm to 4×12 mm. Femtosecond laser eases LASIK fears - All About Vision During laser cutting of soft tissue, a thermal interaction occurs: the laser radiation is absorbed by the tissue, resulting in a rise of temper-ature and the eventual evaporation of the water mol-ecules in .
