Comparative Analysis of 3D-Visualization System and Traditional Microscopic in Surgery for Vitreoretinal Diseases

Purpose. Comparison of the safety, efficacy and results of vitreoretinal surgery using a three-dimensional imaging system in comparison with a standard microscope.Material and methods. The study included 90 patients (92 eyes) operated on by one surgeon for various diseases of the vitreous body and retina. The main group consisted of 43 patients (45 eyes) who underwent vitrectomy using 3D NGENUITY imaging system (Alcon), and the control group consisted of 47 patients (47 eyes) operated on a standard microscope. The minimum follow-up period was 3 months. The result of the assessment of changes in the best corrected visual acuity (BCVA), time spent on the operation, anatomical results, intra-and postoperative complications.Results. The compared groups did not differ in age and sex characteristics, axial length of the eye, duration of observation, categories of diagnosis. Both groups showed a significant increase in visual acuity by the end of follow-up (p<0.05), with no significant difference between them. A positive anatomical result was achieved in both groups (p=872). The mean time of operation in the main group (50±22.6 min) was not much longer than in the control group (48±17.4) (p=0.889). The frequency of postoperative complications during follow-up was the same in both groups: 10.9% in the main group and 10.2% in the control group (p=932).Conclusion. Operations on a 3D imaging system and a standard microscope yielded comparable results with respect to changes in visual acuity, anatomical outcomes, the frequency of complications and the time spent on the operation. 3D-vitrectomy can be considered as a treatment option for patients with various vitreoretinal diseases
