»MYTH No. 1: Autologous serum is a treatment of last resort mostly used by cornea specialists
FACT: Although ASEDs are not an entry-level treatment for dry eye, they are certainly not the most aggressive treatment option available either. In the dry eye setting, ASEDs are commonly prescribed for very symptomatic patients who do not achieve sufficient relief from artificial lubricants and for those with concerning levels of keratitis (regardless of symptoms).
We also use ASEDs very early in the treatment course. In my view, every comprehensive ophthalmologist should consider ASEDS as part of their armamentarium, for 3 reasons. First, the drops, which are derived from a patient’s own serum, are very safe for the patient, with very few adverse events reported in the literature.1,2
For the clinician, the process of prescribing ASEDs today is no more difficult than writing any other prescription (see myth No. 2). And finally, ASEDs offer a unique mechanism of action that complements other therapies.
»MYTH No. 2: Getting ASEDs into patients’ hands is a complex process
FACT: This used to be true, but today, I can prescribe ASEDs as I would any other therapy, thanks to a turnkey operation available from Vital Tears. I simply write a prescription, which my technician enters into a web order form with the patient identification details, and Vital Tears arranges the rest.
The patient can choose to have blood drawn at a designated lab facility, in a doctor’s office, or by a mobile phlebotomist at home. The blood is centrifuged to separate the solid platelets and red and white blood cells from the liquid serum. The serum is sent to a central lab in Kansas City, where it is diluted, bottled, and packaged for delivery.
»MYTH No. 3: Patients will not be willing to absorb the cost or hassle of ASEDs
FACT: ASEDs need to be frozen or refrigerated and typically are not covered by insurance, so there are some differences between these and ordinary topical medications.
However, patients who are prescribed ASEDs are often in considerable distress and are very willing to follow the simple storage directions for the tradeoff of easing their pain and improving their vision. They keep 1 bottle per week in the refrigerator, with the rest frozen until needed. Patients can expect to see an improvement in their symptoms within 7 to 10 days.
When I think about my patients with dry eye on ASEDs, there are very few instances when patients have said, “You know, this really isn’t helping me and I want to stop it.” I get that report all the time from patients on the topical anti-inflammatory agents we prescribe for dry eye, due to lack of efficacy, discomfort, inconvenience, or cost.
»MYTH No. 4: It’s not safe to use blood products
FACT: In the past, this was absolutely true, because preparing ASEDs could expose the physician, pharmacist, and/or technicians to bloodborne infectious agents.
Today, with the Vital Tears ASEDs that we use or other local phlebotomy/eye bank sources that doctors have identified, blood products are handled only by those trained to work with blood and human fluids and are prepared under sterile conditions with strict quality controls.
Under these conditions, ASEDs are arguably safer for patients than many other medications we prescribe because an autologous drop would not be expected to have any corneal toxicity.
»MYTH No. 5: There is no evidence that ASEDs are effective
FACT: ASEDs have been shown in the literature to have very good results in many subsets of patients, including those with dry eye,2-5 autoimmune disease,6 slow or nonhealing epithelial defects,7,8 and chemical injury.9
Randomized, controlled studies would be beneficial, but clinicians can feel very comfortable that ASEDs have a long history of safe and effective use.
Moreover, treatment algorithms from the American Society of Cataract and Refractive Surgery, the Tear Film and Ocular Surface Society, and the International Task Force on Dry Eye all incorporate ASEDs as a recommended treatment for moderate to severe dry eye.10-12
