Lasting relief from Medi Eslani, MD, FAAO (a fellowship-trained surgeon and published ocular surface researcher), using the most advanced therapies available, from autologous serum and amniotic membrane to LipiFlow and IPL.

Understanding the Problem

More than “just dry eyes”

Ocular surface disease affects how comfortable you feel and how clearly you see, and it's far more common than most people realize.

What is ocular surface disease?

Your tears aren't just water. They're a finely balanced film of water, oil, and mucus that keeps your eye smooth, clear, and comfortable. When that film breaks down (too few tears, poor-quality tears, or blocked oil glands known as meibomian gland dysfunction), the surface becomes inflamed and unstable. That's ocular surface disease (OSD); dry eye disease is its most common form.

Signs you may have it

Burning, stinging, or grittiness
A foreign-body or “sandy” feeling
Watering or reflex tearing
Fluctuating or blurry vision
Redness, irritation, tired eyes
Contact lens intolerance

Types

Which type of dry eye do you have?

Dry eye is not one condition, and this is the single most useful thing to understand about it. Treatment that works beautifully for one type does very little for the other, which is why so many people cycle through artificial tears for years without real improvement. Working out which mechanism is driving your symptoms is the first job of the evaluation.

The most common form

Evaporative dry eye

Your eye makes enough tears, but they evaporate too quickly because the oil layer that should seal them in is missing or of poor quality. The usual cause is meibomian gland dysfunction, where the oil glands along your eyelid margins become blocked or their secretions thicken. Adding more watery drops achieves little, because the problem is the oil rather than the water.

Less common

Aqueous-deficient dry eye

The lacrimal glands simply do not produce enough tear volume. This is the type most associated with autoimmune conditions such as Sjogren's syndrome and rheumatoid arthritis, with age, and with certain medications. Here, conserving and supplementing tears genuinely does help.

Very common in practice

Mixed

Many people have both, and the balance between them shifts over time. That is why a good plan is reviewed and adjusted rather than set once and left alone. Sorting out the proportion is precisely what the testing is for.

Diagnosis

How dry eye is actually diagnosed

Symptoms alone are a poor guide. Some people with significant surface damage report surprisingly little discomfort, while others with mild findings are genuinely miserable, and the two types of dry eye can feel identical from the inside. Objective measurement is what separates a real plan from guesswork.

Tear quality

Tear film break-up time

A small amount of dye shows how long your tear film stays intact between blinks. A film that breaks up within a few seconds points strongly toward the evaporative type and toward oil gland dysfunction as the driver.

Surface damage

Ocular surface staining

Dyes reveal where the surface cells of your cornea and conjunctiva have been damaged. The pattern of that staining indicates not only how severe the disease is, but frequently what is causing it.

The glands themselves

Eyelid and oil gland assessment

Your eyelid margins and the oil glands within them are examined directly, and the glands can be imaged to show whether they are blocked, shortened, or have dropped out altogether. Gland loss is permanent, which is why finding it early matters.

Volume and inflammation

Tear production and inflammatory markers

Tear volume is measured where aqueous deficiency is suspected, and testing can confirm whether active inflammation is driving your symptoms. That answer changes whether anti-inflammatory treatment is likely to help you.

The point of testing is not thoroughness for its own sake. It is to identify which mechanism is driving your symptoms, so the treatment chosen actually addresses it.

For Glaucoma Patients

If you have glaucoma, your dry eye is connected

Most patients on glaucoma drops develop ocular surface disease. Years of daily drops (especially preserved ones containing BAK) inflame and damage the surface, causing burning, redness, and fluctuating vision. It can even make your glaucoma harder to monitor and your drops harder to tolerate.

The solution: fewer drops, a healthier surface

As both a fellowship-trained glaucoma specialist and a published ocular surface expert, Dr. Eslani treats the whole picture. He can reduce, or even eliminate, your drop burden with SLT laser, sustained-release implants (Durysta, iDose), and MIGS, while simultaneously healing your ocular surface with advanced therapy. Very few surgeons offer this combined expertise.

Advanced Treatment

Therapies beyond eye drops

When over-the-counter drops aren't enough, Dr. Eslani offers the full range of modern, evidence-based dry eye treatment.

Targeted prescription therapy

Anti-inflammatory drops and prescription treatment to calm the surface and restore your natural tears.

LipiFlow & gland treatment

Gentle thermal pulsation that clears blocked oil (meibomian) glands, treating the most common cause of dry eye at its source.

IPL: Intense Pulsed Light

In-office light therapy that reduces inflammation and restores oil-gland function for lasting relief from evaporative dry eye.

Autologous serum tears

Custom drops made from your own blood, rich in natural healing factors, for moderate-to-severe dry eye that resists standard drops.

Amniotic membrane

A regenerative graft that rapidly heals a damaged ocular surface, reducing inflammation and scarring.

Punctal plugs & scleral lenses

Tiny plugs that preserve your natural tears, and specialty lenses that bathe the eye in moisture for severe cases.

What to Expect

What each treatment actually involves

Dry eye treatment works as a ladder, and most people need more than one rung of it. Here is what the main in-office therapies involve in practice, so you know what you are agreeing to before you agree to it.

One in-office visit

LipiFlow thermal pulsation

Applies controlled warmth to the inner surface of the eyelid while gently massaging the outer surface, melting and expressing the hardened oil that is blocking your glands. The treatment takes about twelve minutes. Improvement builds over the following weeks rather than arriving immediately.

A short series

IPL light therapy

Intense pulsed light is applied to the skin around the eyes, reducing inflammation and improving oil gland function. It is normally given as a series of sessions a few weeks apart, with occasional maintenance afterward, and it is particularly useful when rosacea is part of the picture.

Made from your own blood

Autologous serum tears

A blood sample is processed into eye drops carrying the natural growth factors your own tears contain. They are used several times daily and are reserved for moderate-to-severe disease that has not responded to standard drops, including surface damage following surgery.

For a damaged surface

Amniotic membrane

A regenerative graft placed on the eye to promote healing and reduce inflammation and scarring where the ocular surface is significantly damaged. Dr. Eslani has published peer-reviewed research on amniotic membrane transplantation.

Expectations

What good treatment actually looks like

Dry eye is a chronic condition. That word disappoints people, but it is the truth, and knowing it at the start is what allows a plan to succeed. Ocular surface disease is managed the way blood pressure is managed, rather than cured the way an infection is cured.

What changes with proper treatment is the trajectory. Symptoms come under control, the surface heals, vision stops fluctuating through the day, and the underlying drivers are addressed rather than masked. Many patients reach a point where they need very little ongoing maintenance.

Realistic timeline

Improvement is measured in weeks, not days

Treatments that address the cause, rather than lubricating the symptom, take several weeks to show their full effect. Gland function recovers gradually and inflammation settles gradually. Judging a treatment after a few days is the most common reason people conclude that nothing works.

What cannot be undone

Gland loss is permanent

Meibomian glands that have completely atrophied do not grow back. That is the strongest argument for treating dry eye properly rather than managing it with lubricating drops for a decade, and it is why imaging the glands early is worth doing.

A Foundation in the Science

Care from an ocular surface researcher

Long before he was your surgeon, Dr. Eslani helped advance the science of the ocular surface. He trained under two of the world's leading cornea and ocular surface experts, Dr. Edward Holland and Dr. Ali Djalilian, and built an internationally recognized research career in stem-cell therapy and ocular surface reconstruction.

His work on limbal stem cells, corneal healing, and amniotic membrane transplantation appears in 70+ peer-reviewed publications and the field's leading textbook. Your dry eye and ocular surface care is guided by someone at the very forefront of the field.

FAQ

Dry eye & ocular surface questions

What's the difference between dry eye and ocular surface disease?
Dry eye is the most common form of ocular surface disease, an umbrella term for conditions that disrupt the tear film and surface of the eye. Treating the whole surface, not just the symptoms, is what gives lasting relief.
I'm on glaucoma drops and my eyes burn. Is that related?
Almost certainly. Years of pressure-lowering drops, especially preserved ones, commonly cause ocular surface disease. Dr. Eslani can reduce your drop burden with SLT, sustained-release implants, or MIGS while treating the surface itself.
What is LipiFlow?
A gentle in-office treatment that warms and clears the blocked oil glands in your eyelids (the root cause of most dry eye), improving your natural tear quality.
What are autologous serum tears?
Eye drops made from your own blood serum, rich in the natural growth factors your tears contain. They are highly effective for moderate-to-severe dry eye that hasn't responded to standard drops.
How does IPL help dry eye?
Intense pulsed light applied around the eyes reduces inflammation and restores oil-gland function, providing lasting relief for evaporative dry eye and rosacea-related disease.
Why don't artificial tears fix my dry eye?
Because for most people the problem is not a shortage of water. In evaporative dry eye, the most common form, the oil layer that should stop your tears evaporating is missing or of poor quality. Artificial tears lubricate the symptom briefly but do nothing to the oil glands causing it, which is what treatments like thermal pulsation and IPL are for.
Is dry eye curable?
It is controllable rather than curable. Ocular surface disease is chronic and is managed much like blood pressure. With the cause correctly identified and treated, most patients get their comfort and stable vision back and need only modest ongoing maintenance.
Can dry eye affect my vision?
Yes, and it is one of the most under-recognised causes of fluctuating vision. Your tear film is the first surface light passes through, so when it breaks up unevenly your vision blurs and then clears when you blink. It also affects the accuracy of measurements taken before cataract or laser surgery, which is why the surface is treated first.
Do I need to stop wearing contact lenses?
Not necessarily, though contact lens intolerance is often the first sign of ocular surface disease. Treating the underlying problem frequently allows people to keep wearing lenses comfortably, and specialty or scleral lenses can be part of the treatment itself in more severe cases.
How is dry eye handled before cataract or LASIK surgery?
Deliberately, and beforehand. An unhealthy tear film makes preoperative measurements less reliable and recovery harder, and both cataract surgery and laser vision correction temporarily worsen dryness. Dr. Eslani assesses and treats the surface before scheduling surgery rather than dealing with it afterward.
