“…A description by Centurion et al 25 can be considered an observation in favor of the existence of the equatorial barrier in the fluid-filled pearly white cataract. The authors refer to the intumescent cataract as a cataract thicker than 5.5 mm with an anterior chamber angle smaller than 45 degrees and a characteristically sphere-shaped lens.…”

“…The profile of the light slit shows an increased convexity in a fluid-filled pearly white cataract or intumescent cataract and a relatively smaller convexity in a fluid-free pearly white cataract or normotensive pearly white cataract. Centurion et al's indices, 25 which use tomography images of the anterior segment, can also help in the clinical diagnosis of these types of cataract. Brazitikos et al's ultrasonographic classification 26 considers a fluid-free pearly white cataract as type II.…”

Brazilian technique for prevention of the Argentinean flag sign in white cataract

We describe a technique that prevents the Argentinean flag sign in white cataract. The technique is based on the intumescent cataract having 2 rather than 1 pressurized compartments within the crystalline lens, the anterior and the posterior. The pressure that pushes the nucleus upward, which is the movement responsible for a radial tear of the anterior capsule, does not come from the vitreous but from the posterior intralenticular pressurized compartment. We also present a nomenclature system to help the phacoemulsification surgeon distinguish the 3 types of senile white cataracts and prevent intrasurgical complications peculiar to each one.

Purpose: to optimize the technique of hypermature Morganian cataract phacoemulsification.Patients and methods. 18 patients (18 eyes) with hypermature Morganian cataract were examined. Group I included 8 patients who underwent surgical intervention according to the improved technology using the iridocapsular retractors. Group II included the retrospective results of phacoemulsification with IOL implantation performed according to a standard technique in 10 patients. The optimizing surgical technique in patients of group I consisted in the consecutive usage of four iridocapsular retractors: when creating a capsulorhexis — to stabilize the capsular bag during the circular rupture of the anterior capsule; during the nucleus phacoemulsification — to stabilize the complex: capsular bag, nucleus, capsular ring — in the sagittal plane and additional (together with the capsular ring) support of the capsular bag fornices.Results. No complications were noted in patients of group I. In patients of group II there were two ruptures of the posterior capsule (20%), two cases of re-implantation of a capsular ring because of the stop of its edge into the fold of the capsular bag fornix, one rupture of the anterior capsulorhexis border without its transition to the posterior capsule. In group I there were no any complications in the postoperative period. In group II we noted two corneal oedemata, Descemet membrane folds, which were jugulated by the conservative treatment on the 4–5th days postoperatively.Conclusion. The optimizing technique of hypermature Morganian cataract phacoemulsification with the use of four iridocapsular retractors and capsular ring allowed reducing the number of intraoperative complications in comparison with the standard technique and making the surgical intervention more effective and safe.

“…Многие авторы отмечают изменение анатомо-топографических параметров переднего отдела глаза при набухающей катаракте [8][9][10][11][12][13]. В первую очередь изменяется толщина хрусталика, которая, по данным разных авторов, варьирует от 4,69 до 5,5-6 мм [6,[14][15][16][17][18][19][20][21][22][23][24].…”
