Dyed, white and iridescent feathers, as well as down feathers, were also included in the study. YAG laser capsulotomy painlessly removes the clouded back lining of the lens, allowing light to pass through to the retina and restore vision. It is not necessary to remove the entire capsule, but only to make an opening in it to allow for the passage of light. Examples include sealing leaking blood vessels, reducing pressure in the eye, replacing the cornea, and removing part of the iris. Q-Switched Nd:YAG Laser has a pulse duration of nanoseconds, while Picosecond Laser has a much shorter pulse duration of picoseconds. 1–0. With the increase of time, the temperature in Nd:YAG rod pump end increases linearly.

Absorption bands of the Nd 3+ ions around 808 nm conveniently match the energy of commercially available high-power multimode diode lasers that serve as the pump. We present a study protocol of a prospective, randomized, active-controlled, investigator-initiated clinical trial comparing a novel non-invasive dual. Potential pitfalls of the procedure include inadvertent damage to the patient’s lens replacement (intraocular lens) or retina, but these are very rare. 4 to 12. The calculated. This application-based laser allows you to perform posterior capsulotomy for a high variety of IOLs and iridotomy. A typical simplified laser configuration is shown in Fig.
