MATERIAL AND METHODS

The patients were divided into two groups: group 1 — the main group — included 29 patients (29 eyes; 47.54%) who underwent cataract phacoemulsification with implantation of iris retractors and capsular ring using the scaffold technique. Group 2 — the comparison group — included 32 patients (32 eyes; 54.46%) who underwent cataract phacoemulsification with implantation of iris retractors and capsular ring using standard technique.

RESULTS

Patients’ visual acuity improved up to 0.53 (0.35; 0.80) in group 1, and up to 0.50 (0.45; 0.80) in group 2 by the time of hospital discharge. At 6 months and 1 year follow-ups, visual functions were equal, in group 1 — 0.70 (0.65; 0.80), in group 2 — 0.70 (0.60; 0.90). The number of intraoperative complications decreased from 8.20% in standard phacoemulsification to 1.64% in scaffold technique. The latter reduces endothelial cell loss by 1.95% in comparison with traditional phacoemulsification over 1 year follow-up. With the scaffold technique, the number of intraoperative complications decreased from 15.63% in group 2 to 3.45% in group 1, the number of postoperative complications — from 43.75% to 31.04%, respectively.

CONCLUSION

The scaffold technique is indicated in pseudoexfoliation syndrome with weakness of zonular apparatus, degree I—II lens subluxation, in hard nucleus with absence of posterior cortical layer, in intumescent cataract, Morgagnian cataract to stabilize the posterior capsule and protect it from rupture.
