Potential Contamination of the G-probe Used for Transscleral Cyclodiode

Abstract

In our opinion the G-probe should not be reused as inadequately reprocessed G-probe can lead to risk of nosocomial infections, serious iatrogenic complications, and medico-legal problems.

32 Cyclodestructive Procedures

“…This alertness should be retained regardless of whether new or old G-probes are used. [29][30] We noticed microscopic contamination of the G-probe by the tear film fluid in all the probes examined by us. The review of literature indicates that repeated use of the G-probe is not uncommon.…”

“…In our opinion the G-probe should not be reused as inadequately reprocessed G-probe can lead to risk of nosocomial infections, serious iatrogenic complications, and medico-legal problems. 30 Underlying diagnosis of neovascular glaucoma is a significant risk factor for hypotony post TCP. Hypotony was defined as IOP <5 at the end of 1-year follow-up period.…”

“…[22][23][24] Histopathological studies of enucleation specimens following laser cyclophotocoagulation (Diode and Nd:YAG laser) and cyclocryotherapy have been performed in humans [25][26][27][28][29] and animals. 12,[30][31][32][33][34][35] We have previously reported histopathology of two cases of clinical failure following Diode laser cyclophotocoagulation. 36 This study examines histological outcomes in nine cases in humans, and correlates this with the clinical c course in each eye.…”

Sterile Single Use Cover for the G-probe Transscleral Cyclodiode

“…[3][4][5] However, each of these have limitations, such as insufficient sterilization, postprocedure residual debris, and the propensity to damage the G-probe device. 3,5,7,8 One potential strategy for maintaining interpatient sterility would be the usage of a disposable barrier to protect the G-probe from contamination. Such a strategy would seem to be ideal, in that it would segregate the lumen of the device from biologic contaminants, thus eliminating the need for potentially damaging flush procedures.…”

“…7 Many cleaning procedures have been proposed including the use of a simple alcohol wipe, ethylene oxide sterilization, and a 70% alcohol flush protocol. [3][4][5] However, each of these have limitations, such as insufficient sterilization, postprocedure residual debris, and the propensity to damage the G-probe device.…”
