Abstract: This study tested the hypothesis that four ocular irrigating solutions were equally irritating during copious irrigation. We conducted a prospective, double-blind study of patients with chemical exposure to the eye. Each underwent cross-over irrigation with all of the following in random order: normal saline (NS), lactated Ringer’s (LR), normal saline adjusted to pH 7.4 with sodium bicarbonate (NS + Bicarb), and Balanced Saline Solution Plus (BSS Plus, Alcon Laboratories, Fort Worth, TX). Compared with traditional NS and LR, NS + Bicarb tended to be more comfortable. BSS Plus was statistically superior (P less than .05) to NS and preferred over LR and NS + Bicarb. Three patients demanded discontinuance of NS or NS + Bicarb infusions. All solutions had comparable normalization of conjunctival pH and degree of injection. Alternate solutions including BSS Plus should be considered for use in those patients whose poor tolerance to normal saline threatens to delay or interrupt eye irrigation following a chemical injury.
MorTan Note: This study, done on patients with actual chemical burns, involved 11 patients and 12 eyes.
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.

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.
