DISTINCTIVE FEATURES OF THE MICROSURGICAL TECHNIQUE OF THE SILICONE OIL TAMPONADE IN APHAKIC EYES
Abstract
Purpose. To optimize the surgical technique of the silicone oil (SO) tamponade in aphakic eyes with the retinal detachment (RD). Material and methods. The RD surgery treatment was performed in 49 eyes of 46 patients. All the patients have undergone pars plana vitrectomy with the silicone oil tamponade. During the operations 20G and 25G instruments were used. All the eyes were aphakic. The technological features of the operation were: the silicone oil injection by the single-step replacing method of per-fluorocarbon liquid for silicone oil, the replacement of substances only on a sealed anterior chamber, the light silicone injection after the pre-contraction of the pupil, the peripheral iridectomy, the injection of the saline solution into the anterior chamber in order to prevent the SO migration during the mydriasis, the injection of the miotic solution into the anterior chamber in case of SO migration. Results. The silicone oil tamponade was performed success-fully in all aphakic eyes. Silicone oil migrated into the anterior chamber intra-operatively in one case (2%) and during the first day after operation in 2 cases (4.1%). In both cases silicone oil was removed from the anterior chamber by injecting the solution of miotic agent. A prominence of the silicone oil surface into the anterior chamber in the pupil area of various intensity degreestook place in 14 cases (28.6%) intra-operatively and in 3 cases (6.1%) in the early postoperative follow-up. Conclusions. The application of the above described technique of operation allows to prevent in proper time the migration of silicone into the anterior chamber of an eye at different stages of treatment, which makes the operation pars plana vitrectomy with silicone oil tamponade an effective and safe method of RD treatment in aphakic eyes.
