Randomized Controlled Trial Comparative Study Clinical Trial[Preoperative use of suction cup oculopression in comparison with Vörösmarthy oculopression].
In contrast to Vörösmarthy oculopression (VOP), suction-cup oculopression (SOP) is "pure" oculopression without compression of orbital tissue. Prior to 44 cataract operations with posterior chamber lens implantation, the authors performed SOP (negative pressure - 110 mm Hg) or VOP (level of oculopression 30 mm Hg) of the same duration (average 26 min). Before oculopression, a retrobulbar injection (RBI) was performed for local anesthesia. ⋯ After RBI + SOP, a post-injection of anesthetic was necessary in three cases; no additional injection was required after RBI + VOP. In conclusion, identical preoperative reductions in IOP can be achieved with SOP and VOP. Regarding the form of the iris-vitreous diaphragm and the frequency of post-injection, the differences between the two methods may be related to the lack of orbital compression during SOP.
