The laser works by the mechanism of photodisruption
in which there is formation of plasma which mechanically displaces and disrupts the surrounding tissue5.
reported Nd:YAG laser photodisruption
of hemorrhagic detachment of the internal limiting membrane in 1989 and it has been used for Valsalva retinopathy since that report .

during femtosecond laser-assisted cataract surgery," Journal of Cataract and Refractive Surgery, vol.
The femtosecond laser has pulse duration of 10-15 and works on the principle of photodisruption
that generates high-intensity electrical field by highly focussed and strong pulses.
After making the lenticule cut and sidecut and moving the patient under the surgical microscope, a blunt spatula was used to enter the area of anterior lamellar photodisruption
and remove any residual material.
(15) Femtosecond lasers work by cutting tissues with a process of photodisruption
, unlike argon (photocoagulation) and excimer (photoablation) lasers.
Further femtosecond laser techniques could function as a sub-micron optical lancet to achieve precise surgery of direct photodisruption
on subcellular structures [2,3].
Nd: YAG laser photodisruption
of Hemorrhagic Detachment of internal limiting Membrane.
The Nd:YAG laser has a pulse duration in the nanosecond range ([10.sup.-9] seconds) and causes photodisruption
at its focal point, such as on the posterior capsule in the treatment of posterior capsular opacification (PCO).
Dr Jordaan then goes on to talk about photodisruption
and optic double diffraction, but does not explain what these are, and when, how and why these are used.
