Purpose
Recently, new pathogenetically justified microinvasive microsurgical interventions for the treatment of glaucoma have appeared. However, in the majority of cases, glaucoma continues to progress and visual functions are lost. The use of ultrasound in the treatment of ophthalmopathology is a promising direction of modern ophthalmology.
Setting
The aim of the work was to develop a multifunctional ultrasonic scalpel for surgical treatment of glaucoma patients by studying the effect of ultrasonic cavitation on eye structures and intraocular fluid composition.
Methods
The criteria for predicting the strength and durability of the use of an ultrasonic scalpel for the surgical treatment of ab interno glaucoma have been developed.
Results
An ultrasound transducer has been developed that will allow the surgeon to accurately dose the power, length, and frequency of ultrasound oscillations, choose different modes of operation, dose the amount of anti-glaucomatous intervention (in the trabecular zone), achieve a decrease in intraocular pressure, and avoid intraoperative complications: corneal edema and loss of endothelial cells. The design is rated for strength, durability and reliability of operation.
Conclusions
The developed ultrasonic surgical scalpel can be used for mini-invasive interventions in glaucoma. Further experimental studies of the influence of ultrasonic cavitation on the composition of the intraocular fluid and the structure of the anterior and posterior parts of the eye will contribute to determining the safety of using an ultrasonic scalpel in clinical practice.
