Abstract: 300 rabbit corneas were burned for – 1 minute by applying a filter paper of 10mm diameter soaked in different concentrations of NaOH. The aqueous humor pH was then measured at certain time intervals and after different treatment methods until the physiologic pH of 7.6 was reached. The results were statistically analyzed. Group 1, 2 and 3 were burned with 1N NaOH and 6N NaOH respectively without any treatment. In these groups, a “therapeutic” pH-level of 8.5 was measured on an average 0.5, 2.5 and 5 hours after the burn. Group 4 and 5 again were burned with 6N NaOH. In Group 4, the burn was followed by constant irrigation with physiologic saline by means of the Morgan Lens®. With this regimen, a pH of 8.5 was reached after 2.5 hours. In Group 5, the physiologic saline solution was replaced by a buffer solution (Isogutt®) and a pH of 8.5 was measured after only one hour. Based upon these results, it is felt that severe lye burns should be treated by constant irrigation with a buffer solution for several hours, a treatment that can easily be performed by use of the Morgan Lens.
Three Army soldiers were on their way to us following an explosion of an improvised device. The driver had goggles on and suffered extensive facial trauma and all three had eye injuries from the debris that hit them. We got bilateral Morgan Lenses in all three and flushed each with several liters of LR. Followed with antibiotics, they were rebandaged and on an emergency air evacuation that evening. These men were grateful for the care they received. The technicians and physicians here are thankful that everyone knew what to do to get the lens system set up and running. I am grateful to you for the opportunity to access the class online and ability to present it shortly after we arrived. One of the others did have a corneal laceration that we could assess after flushing. We feel confident that all will have the best outcomes thanks to the Morgan Lens use.
We also had a patient who experienced an electrical explosion (a generator) to his face. We used Morgan Lenses to irrigate his eyes and sent him on an air evacuation flight to Germany. He has since returned to duty and is doing well with minimal residual sight loss.Military Registered Nurse (Active Duty)
The Morgan Lens is used in 90% of hospital emergency departments in the USA and can be inserted in less than 20 seconds. There simply is no other "hands-free" method of eye irrigation. Nothing else frees medical personnel to treat other injuries or to transport the patient while irrigation is underway. Nothing is more effective at treating ocular chemical, thermal, and actinic burns or removing non-embedded foreign bodies, even when the patient's eyes are closed tightly. Its design makes it simple and straightforward to use so minimal training is required.
