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.
The Morgan Lens has proven to be an indispensable aid in my thirteen years of emergency practice. During that time, my work has taken me to eight or ten different hospitals and medical centers, and I'm always happy to say each and every one of them has kept the Morgan Lens in stock and at the ready. And, each time a patient is suddenly presented with a chemical or other toxic eye exposure, it is immediately apparent that there is simply no substitute for this product. In these situations, I have come to depend on it. I think this testimonial simply reflects what every other emergency physician knows about your landmark device.
...could not effectively irrigate his eyes with IV tubing...Physician (California)
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.
