Summary:
The purpose of the study is to develop an objective method for calculating the square of the iris defect area. Material and Methods. Clinical and functional surgical treatment results for 98 patients (98 eyes) with the consequences of traumatic damage of the eyeball's anterior part were analysed. The uncorrected visual acuity (UCVA) was 0.12±0.05, and the best corrected visual acuity (BCVA) was 0.41±0.15. Results. In orderto objectively assess the iris defect area, we developed a grid palette. We calculated the square of iris defect area using this palette in percent, after this surgical algorithm was determined. The visual functions in all patients after the treatment were increased and by the seventh day after the surgery were as follows: UCVA0.58±0.28; BCVA0.71±0.15. Conclusion. Using the designed palette for objective assessment of the iris defect area helps to choose the correct algorithm of surgery. In cases when the iris defect square is less than 30%, it is possible to use the technique of closed iridoplasty with patients own eye tissues. If the iris defect area is more than 30%, implantation of the iris-lens diaphragm is recommended.
