ABSTRACT
The results of 257 combined, pathogenically oriented operations were analyzed in 181 patients with cataract concurrent with open-angle glaucoma (OAG). A system of pathogenically oriented combined surgical interventions was shown to be highly effective in patients with cataract concurrent with OAG. The proposed procedure for intraoperative determination of the retention of intraocular fluid allows a pathogenically oriented antiglaucomatous component of combined surgery to be chosen in patients with cataract and OAG. Increased visual acuity and stable stabilization of the glaucomatous process were achieved in all cases during a follow-up of less than 3 years.

The study results showed a principle possibility to fragmentize the most dense lens nuclei by means of a nylon cutting loop. The safety and efficiency of applying a loop fragmentizer in phacoemulsification of high-density cataract were equally demonstrated. The method advantages are conditioned by that a preliminary splitting of the nucleus into fragments without trenches being shaped cuts essentially the total capacity and duration of ultrasound impact, thus, the irrigation time and the needed volume of balance salt solution also decrease intraoperatively: it, naturally, diminishes the generally-known traumatic aftermaths of surgical intervention.

Clinical estimation of different modifications of phacoemulsification revealed the formation of the second tunnel in the nucleus for its division into quadrants in "four-quadrant phaco" increases the required duration of ultrasonography (US) and irrigation, which causes greater endothelial losses associated with the use of nuclear breakdown by means of a chopper tunnel. When the authors used their own methods of "extracapsular half-nuclei" fragmentation, endothelial losses are rather greater than those with the similar method "stop & "chop", which is associated with closer disposition of the US tip to the posterior corneal surface. At the same time nuclear breakdown by means a chapper in the capsular sac by the "stop & chop" method causes dilation of Zinn's ligaments, fraught by their rupture, particularly if latent derangement or defects of the zonular apparatus, and increases the risk of damage to the posterior capsule by the chopper.
