What it is
Autologous serum tears are eye drops made from a person's own blood. A pharmacy prepares them by separating the serum and diluting it with a sterile solution. They are compounded for an individual patient and are not an FDA-approved drug.
Amniotic-derived eye drops and serums are made from donated amniotic tissue, which comes from the placenta after a planned birth. Most of these drops and serums are also not FDA-approved as drugs. Some amniotic membrane devices, such as tissue placed on the eye's surface by a clinician, are regulated as human tissue products, which is a different regulatory pathway. Processed amniotic products are not stem-cell treatments, and most contain no living stem cells after processing.
A third category, allogeneic serum tears, is made from donor blood rather than the patient's own. Which of these options, if any, is appropriate depends on your eyes, your health history, and an evaluation by a licensed eye doctor.
How it’s traditionally been approached
Dry eye has traditionally been approached in steps, often starting with lubricating drops, lid care, and changes to environment and daily habits. Eye doctors also look at underlying factors such as eyelid gland function, inflammation, and other health conditions.
Serum tears have long been discussed as an option for some people with more stubborn surface problems, in part because serum contains natural components found in tears. Because they are compounded, availability, preparation standards, and cost can vary between pharmacies.
Amniotic products are a newer part of the conversation. Some are drops or serums, and others are devices placed on the eye by a clinician. Because the products, sources, and processing methods differ, it helps to compare them one at a time rather than treating them as the same thing.
How the right eye doctor may help
A good first step is a comprehensive dry eye evaluation with a licensed eye doctor. A visit generally includes a conversation about your symptoms, medications, and health history, followed by an examination of the surface of your eyes and eyelids. The goal is to understand what may be contributing to your discomfort.
Your doctor may talk through a range of possibilities, from simple measures to biologic options, and explain which may or may not fit your situation. Only a licensed clinician can decide what is appropriate after an evaluation, and no option is guaranteed to work.
If a biologic product comes up, consider asking: What is this product, and where does it come from? How is it processed or compounded? What is its FDA or regulatory status? What is the total cost, including follow-up visits? What should I watch for, and when should I call you? Providers.plus lists licensed providers if you'd like to find one.
The whole-person view
Living with dry, irritated eyes can be tiring. Discomfort can affect sleep, concentration, screen time, and mood, and stress can in turn make people more aware of physical symptoms. Body, mind, and stress influence one another.
Some people find it helpful to pair eye care with supportive practices. Somatic Experiences offers body-based support for stress, and Therapists.plus connects people with talk therapy. These are complements to, not replacements for, care from your eye doctor.
Keep in mind
- Autologous serum tears are pharmacy-compounded and not an FDA-approved drug, and most amniotic-derived drops and serums are not FDA-approved as drugs either; some amniotic membrane devices follow a different human tissue pathway.
- Never start, stop, or change any eye product without guidance from a licensed eye doctor, since eye infections and other serious conditions need professional care.
- Sudden vision changes, severe eye pain, or a suspected eye injury need urgent attention; call 911 for emergencies. If you're in emotional crisis, call or text 988.
- No product is guaranteed to relieve symptoms, and results vary from person to person.

Frequently asked questions
What is the difference between amniotic and serum tears for dry eye?
Serum tears are usually made from a person's own blood (autologous) or from donor blood, while amniotic products come from donated amniotic tissue. Both are biologic and neither category is generally an FDA-approved drug as a drop or serum. A licensed eye doctor can explain which, if either, may be worth discussing for you.
Are amniotic eye drops FDA-approved?
Most amniotic-derived eye drops and serums are not FDA-approved as drugs. Some amniotic membrane devices placed by a clinician are regulated as human tissue products, which is a different pathway. Ask your provider about the specific product's regulatory status.
Are autologous serum tears FDA-approved?
No. Autologous serum tears are compounded by a pharmacy from the patient's own blood and are not an FDA-approved drug. Preparation can vary, so it's reasonable to ask your doctor about the pharmacy and process.
Are amniotic eye drops stem-cell treatments?
No. Amniotic products should not be described as stem-cell treatments, because most contain no living stem cells after processing. Ask the provider what the specific product contains and how it is processed.
Which is better for dry eye treatment, amniotic or serum tears?
There is no one-size-fits-all answer, and only a licensed eye doctor can say what is appropriate after an evaluation. The choice may depend on your eye findings, health history, product availability, and cost. Bring questions about each option to your visit.
What should I ask my eye doctor about biologic dry eye treatment?
Ask what the product is, where it comes from, how it is processed or compounded, and what its FDA or regulatory status is. Also ask about the total cost, follow-up visits, and warning signs to watch for. This helps you compare options clearly.
