iDose TR Sustained-release Travoprost Implant for the Treatment of Glaucoma

There are several barriers to patient adherence in glaucoma treatment, such as complex dosing regimens, side effects and difficulties with eyedrop administration. This article discusses these challenges, and how they have led to the development of novel sustained-release platforms for glaucoma medications. These platforms include extraocular and intraocular options, such as wearable ocular surface devices, punctal plug systems, subconjunctival injections and intracameral implants. In particular, we focus on the iDose^® TR (Glaukos, San Clemente, CA, USA) sustained-release travoprost titanium implant. It is a particularly promising option, which continuously elutes travoprost at therapeutic levels over an extended period. Phase III trial results have shown its efficacy in lowering intraocular pressure. Notably, the implant typically lasts for around 4–5 years and can be safely exchanged with a new one after it finishes its therapeutic effect. This advancement in glaucoma treatment offers a new alternative to traditional treatment modalities. Real-world trials are needed to shed more light on the efficacy and safety profile of iDose TR.
