Narrative Responses:

Purpose
To study  condition of retinal pigment epithelium after cataract extraction   using energy of ultrasound and laser.

Methods
Laser cataract extraction was performed in  3 left cadaver human eyes. Ultrasound phacoemulsification (Millennium) was performed in  3 right eyes (male, 68-72 years) of the same individuals using the Russian device “Rakot” (Nd-YAG  1.44 µm). Electron transmission microscopy of pigment epithelium in macular area of retina was carried out.

Results
After laser operation the ultra-structure of nucleus, nuclear membrane and chromatin corresponds completely to the norm. After ultrasound phacoemulsification the electron optical density of cell cytoplasm is porous. Many vacuoles were available in cells cytoplasm.

Conclusion
Laser energy for the posterior segment of the eye is a safer one of two energy types which are used in cataract surgery.
