Femtosecond laser in cataract surgery

Femtosecond laser uses an infrared beam of light to precisely separate tissue through a process called photodisruption by generating pulses as short as one-quadrillionth of a second. It has wavelength of 1053 nm and is based on the technology whereby focused laser pulses divide material at the molecular level without transfer of heat or impact to the surrounding tissue.

EPIBULBAR LESIONS

Epibulbar lesions are formed particularly in the conjunctiva and cornea. These lesions are classified into two distinct types that include pigmented and non-pigmented epibulbar lesions. The pigmented epibulbar lesions are those lesions that have pigments while the non-pigmented lesions are those that are translucent or transparent due to the absence of the pigments.
