Iatrogenic Breaks in Microinvasive Ultrasonic Vitrectomy Surgery of Rhegmatogenous Retinal Detachment
Abstract
One of the challenges in vitrectomy surgery of rhegmatogenous retinal detachment is the occurrence of iatrogenic retinal breaks, with reported frequencies ranging from 2% to 14%. This complication is attributed to traction resulting from non-linear aspiration flow in guillotine principle-based vitrectomy. Ultrasonic vitrectomy, based on the energetic fragmentation of the vitreous body, provides a 100% duty cycle of the instrument, thereby creating a more uniform aspiration flow.
The purpose. To study the frequency and causes of iatrogenic ruptures in surgery of regmatogenic retinal detachment by microinvasive ultrasonic and pneumatic vitrectomy 25G in a comparative aspect.
Material and methods. Patients were divided into the main group (n = 61, USVE operations) and the control group (n=73, PGVE operations). Endovitreal interventions were performed according to the standard technique using the «Optimed Profi» microsurgical system. Vitrectomy procedures were performed according to standard techniques using the «Optimed Profi» system.
Results. The frequency of iatrogenic retinal breaks in the main group was 3.28%, compared to 8.22% in the control group (p=0.23).
Conclusion. The obtained data indicate a trend toward a reduced risk of iatrogenic retinal breaks when using ultrasonic technology; however, further studies with an expanded sample size are required to confirm this advantage.
