Semifluorinated Alkanes: Uses, Common Brands, and Safety Info

Semifluorinated alkanes are a versatile class of drugs used in ocular surgery and corneal disorders. They act as intraocular tamponades, providing support during surgery and promoting healing. Common brands include Oxane® HD and F6H8®. Adverse effects are generally mild and transient. Proper use under medical supervision is crucial.


Semifluorinated alkanes are a class of drugs that have been developed for use in ocular surgery and corneal disorders. These compounds are unique in that they combine the properties of both perfluorocarbons and hydrocarbons, making them highly versatile in ophthalmic applications. Semifluorinated alkanes are typically used as intraocular tamponades, which means they are used to temporarily fill the space in the eye during surgery or to facilitate the healing process in certain corneal conditions.


Semifluorinated alkanes find their primary use in ophthalmology, specifically in the treatment of retinal detachments, macular holes, and other vitreoretinal disorders. In these conditions, these drugs are injected into the eye to create a temporary internal tamponade, providing mechanical support to the retina and promoting its reattachment or healing. This tamponade effect helps to ensure proper healing and minimize the risk of complications. In addition to their use in surgery, semifluorinated alkanes have shown promise in the management of dry eye disease. These compounds can form a stable layer on the ocular surface, reducing evaporation of tears and improving lubrication. Some experimental studies suggest that semifluorinated alkanes may have antioxidant properties, which could further contribute to the management of ocular surface disorders.

Common Brands

While there are several formulations of semifluorinated alkanes available, two commonly used brands are Oxane® HD and F6H8®. These brands have been extensively studied and have demonstrated efficacy and safety in various ophthalmic conditions. It is important to note that the availability of specific brands may vary by region, and it is always recommended to consult with a healthcare professional for specific product recommendations.


Semifluorinated alkanes have been generally well-tolerated in ophthalmic use. Adverse effects are typically transient and mild, including blurred vision, increased intraocular pressure, and floaters. These effects usually resolve spontaneously over time. As with any medication, there is a potential risk of allergic reactions, so individuals with known hypersensitivity to semifluorinated alkanes should avoid their use. It is crucial to follow the instructions provided by the healthcare professional regarding the administration and duration of therapy with semifluorinated alkanes. These drugs should only be used under the supervision of a qualified eye care specialist, as their misuse or inappropriate application can lead to complications or undesired outcomes. In conclusion, semifluorinated alkanes are a valuable class of drugs used in ocular surgery and the management of corneal disorders. They provide temporary support to the retina during surgery, promoting healing and minimizing complications. Furthermore, these compounds have potential benefits in managing dry eye disease. As with any medication, it is important to use semifluorinated alkanes as directed by a healthcare professional and to report any adverse effects experienced during their use.
