Editor’s Note: Welcome to “Let's Chat,” a blog series featuring contributions from members of the ophthalmic community. These blogs are an opportunity for ophthalmic bloggers to engage with readers with about a topic that is top of mind, whether it is practice management, experiences with patients, the industry, medicine in general, or healthcare reform.

Many medical specialties share medications and technologies, from various classes of drugs to diagnostic testing and surgical instruments. In ophthalmology, we tend to see ourselves as set apart from most specialties because of the unique needs and limitations of working with the eye. We’ve seen a few noticeable crossovers recently, however, particularly from aesthetics. Here are just a few “adopted” technologies we’re happy to see in the hands of ophthalmologists.
Intense pulsed light (IPL) therapy
IPL therapy has been used in aesthetics since the 1990s to improve skin texture and treat rosacea. First-generation platforms required tremendous expertise, but newer, sixth-generation technologies (Optima IPL with the OPT technology, Lumenis), coupled with corneal shields, have the safety profile needed to address the eyelid and adnexa, particularly targeting telangiectasias associated with ocular inflammation.
We do not yet have published papers comparing the clinical efficacy of treating directly on the eyelids (with large, laser-grade, corneal-shield protected globes) compared to treating outside the orbital rim (with disposable laser-grade external ocular shield stickers).
Dozens of peer-reviewed papers report the efficacy of IPL as an effective drug-free approach to treating ocular rosacea-associated and non-rosacea-associated meibomian gland dysfunction (MGD) and DED. This effect is thought to occur via multi-level impacts on the inflammation factors that drive both the MGD and DED components of ocular surface disease.1
IPL has been shown to improve noninvasive tear breakup time more than 5 seconds over baseline, and 86% of patients report improved symptoms.2 With three or four IPL treatments, spaced 2-5 weeks apart, we observe statistically significant reductions in MMP-9 levels and improved tear osmolarity.3
Patients then repeat IPL 1 or 2 times per year, depending on the severity of the underlying disease comorbidities. Additionally, recent confocal microscopic evidence exists for microstructure improvements of meibomian glands as well as significant decreases in peri-glandular inflammatory cells with IPL therapy.4
Patients report high satisfaction and appreciate the aesthetic benefits, such as improved eyelid redness, conjunctival redness and facial flushing.
Botulinum toxin A (BTA) (Botox, Allergan; Dysport, Galderma; Xeomin, Merz Aesthetics)
Once an orphan drug, BTA demonstrated efficacy in the treatment of strabismus because of its ability to selective relax muscles and was subsequently used for various facial spasms and aesthetics, as well as pain and autonomic disorders.5,6
Recently, neurologists and ophthalmologists have been exploring BTA’s potential for treatment of neuropathic pain syndromes.7,8 Strategic injection of BTA also could produce any number of benefits to the ocular surface by addressing corneal allodynia and neuralgia of the ophthalmic branch of the trigeminal nerve.
In ophthalmology, BTA injections in young aesthetic patients can mitigate lateral canthal rhytids addressing decreased Schirmer’s testing and tear breakup time.9
Conversely, in patients with blepharospasm and concurrent DED, strategic injection at the lateral canthus and pretarsal orbicularis can improve symptoms and reduce inflammatory cytokine production.10
In refractory filamentary keratitis patients, a similar low-dose pre-tarsal injection technique was shown to resolve filaments in nearly 90% of patients.11 A single lower eyelid injection medial to the punctum can weaken the Horner’s muscle, reducing tear drainage by approximately 40%.12
This technique also increases post-LASIK patient satisfaction by reducing lubricant dependency, with fewer complications than silicone punctal plugs.13 Injections in the lacrimal gland have helped patients with epiphora due to hyperreflexive lacrimation.14 Lastly, injected specifically to induce ptosis, BTA can offer a temporary tarsorraphy to protect the ocular surface.
In recent years, we have seen several topical medications migrate both ways between aesthetics and ophthalmology. Few other ophthalmic pharmaceuticals have successfully transitioned into the aesthetic world like the topical drug, bimatoprost. Widely used for glaucoma, the drug’s side effect of increased eyelash growth led to its rebranding for aesthetic treatment of hypotrichiasis (Latisse, Allergan).
Unfortunately, in addition to the aerodynamic impacts on evaporative dry eye from the abnormal eyelash lengthening effect associated with overuse, prostaglandins can also create lid margin redness, discoloration, dermatitis, and exacerbation of MGD.
XAF5, a topical prostaglandin ointment by Topokine Therapeutics, is undergoing phase 2b/3 trials to assess its efficacy in treating lower eyelid steatoblepharon, capitalizing on the side effect of periorbital atrophy induced by topical ophthalmic prostaglandin analogs for aesthetic use.15
The potential for MGD exacerbations, dermatitis, eyelid hyperpigmentation, and other side effects associated with this modality of aesthetic treatment may pose issues if it becomes FDA approved.
Hyaluronic acid gel (HAG) fillers
Hyaluronic acid gel (HAG) fillers have been used in intraocular surgery for decades. The aesthetic uses of HAG products such as Juvederm (Allergan) and Restylane (Nestle Skin Health) are well known and offer a popular method of non-invasive facial rejuvenation. However, more recently, the functional use of fillers to improve eyelid malposition or mid-face revolumization has shown promise.
HAG has been found to be as efficacious as allograft dermal grafting or hard palate grafting to improve the position of the lower eyelids,16 as well as to improve and restore normal eyelid anatomy to correct lagophthamos, congenital ectropion, upper eyelid retraction, among other malpositions.17
Clearly, ophthalmology, dermatology, and aesthetics benefit each other through shared medications and technologies. In the future, we anticipate seeing many more crossovers and “adopted” technologies used routinely in ophthalmology.
