Clinical Trial Summary

This is a randomized controlled trial that seeks to examine the effectiveness of Eyeprotx™ protective goggles in comparison to traditional methods against ocular injury that can occur perioperatively under general anesthesia.


Description:

Ocular injury is but a devastating condition that can occur perioperatively under general anesthesia. Corneal abrasion is the most common ocular injury during general anesthesia, surpassing case incidence of damage caused by patient movement in ophthalmologic surgery. Causes of ocular injury include corneal drying due to the suppression of tear ducts from anesthetic agents, direct physical trauma, or agitation from the volatile anesthetic used. Ocular injury may also occur due to bacterial infection with MRSA, preventative methods, or rubbing of the eyes postoperatively due to agitation. Agitation may be caused by corneal drying or by shift or disruption in rapid eye movement sleep cycle from light penetration through the eyelids. Attempts at prevention of corneal abrasion have been used, including taping the eyelids shut, manual eye closure, paraffin-based ointment application into the conjunctival sac, and the use of hydrophilic contact lenses, although only a few studies have validated the comparison of these methods' effectiveness.

Eyeprotx™ Protective Goggles have been designed specifically for use in the operating room or in any scenario where general anesthesia must be used, such as intubation in an emergency. Current ocular protective measures such as tapes during anesthesia have been associated with injury and infection. With this study, we hope to find a safer preventative technique against ocular injury during the perioperative period.

Intervention

Device:
Eyeprotx™ General Anesthesia Protective Goggles
Eyeprotx™ Protective Goggles have been designed specifically for use in the operating room or in any scenario where general anesthesia must be used, such as intubation in an emergency. The integral function is to reduce intraocular pressure while in place, prevent operating room bright light penetration, facilitate a swift placement preventative measure with straps, form a barrier against bacterial invasion and mechanical damage. This study would seek to examine this goggles' effectiveness as a preventative measure as vs. other measures.
Eyelid Tape
Taping the eyelids during intubation is one of the standard techniques used perioperatively under general anesthesia. This intervention would be used for the Eyelid Tape Group.
Eye Ointment
Another standard technique used perioperatively under general anesthesia is to apply an ointment to the eye for lubrication. This intervention would be applied to the Eye Ointment Group.

Outcome

Type Measure Description Time frame Safety issue
Other Usability Scale Per Operator The anesthesiologists and nurse anesthetists working on the trial will be asked to complete a usability scale questionnaire to evaluate the effectiveness of the different variation of the goggles, such as goggles with a strap versus goggles with short sterilized adhesive tape. This measure will be evaluated up to 6 months after the post-surgical operation.
Primary Changes in Baseline Ocular Condition post-operatively The following will be measured upon evaluation, using a numerical scale of 1 to 8, with 1 being complete absence of condition and 8 being the most severe presentation of the condition:
1. eye discomfort, 2, pain, and 3. dryness intensity, each on a numerical rating-scale of 1 to 8, The measures will be compared among the goggle, ointment, and tape groups.
The patient's initial rating will be recorded approximately ten minutes before surgery at the point of anesthesia evaluation and will be reassessed up to 24 hours post-operatively.
Primary Incidence of Ocular Complications post-operation Incidence of corneal abrasion, conjunctivitis, MRSA infection, and direct ocular trauma will be assessed by the anesthesiologist or nurse anesthetist and will be recorded upon diagnosis of condition for all groups. Evaluation of these complications will be done from the point the patient has returned to the recovery room to up to one week post-surgery or until discharge, whichever comes first.
Secondary Patient Awareness during Anesthesia Patient awareness of being under anesthesia will be recorded qualitatively, with accounts of anxiety and/or fear being noted, if applicable. This measure will be evaluated up to 48 hours post-surgical operation.
Secondary Incidence of Nightmare during Use Patient's report of experiencing nightmares during the surgery will be recorded qualitatively. This measure will be evaluated up to 48 hours post-surgical operation.
