Anew vitrectomy machine using a fluid control system allows safer and more precise surgery, with considerably lower failure rates, a study shows.
Vitrectomy is a fundamental surgery for patients affected by retinal detachment, retinopathies, macular diseases, and vitreous hemorrhage. Although more than 500 000 vitrectomy procedures are performed every year by physicians worldwide, vitrectomy is still considered
a delicate surgery that can lead to severe intraoperative and postoperative complications.
According to Didier Ducournau, MD, although there has been a large shift toward vitrectomy in the past
2 decades, evidence-based data proving that vitrectomy is a superior technique to the older scleral buckling are still lacking.
“Until now, the largest study was the Scleral Buckling Versus Primary Vitrectomy in Rhegmatogenous Retinal Detachment (SPR) study on 681 cases treated by 46 surgeons of 5 countries.1 They spent 6 years of work
to compare and analyze these cases, and no definitive conclusion was achieved. Why was no definitive conclu-sion achieved? Because, statistically, we cannot prove anything out of 681 cases. To have a statistically signifi-cant result, we should work on 5000 cases, and a ran-domized study of 5000 cases costs several million euros. Who would sponsor such a study?” he said.
New studies, in his opinion, should not concentrate purely on the results, but rather, compare the effect of any data to find the key factors for improving safety, effi-cacy, and standardization.
In a meeting organized by Dr. Ducournau at the Clinique Sourdille in Nantes, France, surgeons discussed the central role of vitrectomy machines, particularly of the new-generation flow-based systems, in ensuring the safety and efficacy of the procedure.
The goal of the congress was to explain why aspira-tion flow control vitrectomy is a safer, faster, and more reliable technique for all of the different pathologies and conditions involving the vitreous.
