Gas permeable (GP) and scleral lenses provide optical precision and therapeutic value that soft lenses often cannot achieve. Whether prescribed for keratoconus, high myopia, irregular astigmatism, or post-surgical corneas, these lenses interact with the ocular surface in fundamentally different ways. Their material properties and tear film dynamics require care systems that are not merely compatible—but specifically formulated.

If you already wear gas permeable (GP) or scleral lenses or you just got your first pair, you know that it is not that easy. Maybe you wear them for keratoconus, high myopia, or because your cornea has an irregular shape. These lenses often give clearer, sharper vision, but they also require a slightly different kind of care. Let’s learn together!

Tear film stability is a central determinant of contact lens tolerance, optical consistency, and long-term ocular surface health. While all contact lens modalities influence tear dynamics to some degree, specialty lenses, such as scleral lenses used in keratoconus management, introduce distinct physiological considerations.

You have a long day at work or traveling ahead of you – now you’re lying in bed, worried, that at noon, your eyes will feel dry and itchy. Dryness during contact lens wear is common, but for people wearing scleral lenses or living with keratoconus, it feels like a nightmare!

If your eyes feel uncomfortable, dry, or irritated after applying your contact lenses, your contact lens fit may not be the only factor. One important part of the contact lens system is often overlooked: the contact lens solution.

The development of a modern multi-purpose solution (MPS) requires a careful balance between antimicrobial efficacy, material compatibility, and ocular surface tolerance. As contact lens materials continue to evolve, particularly in the areas of specialty lenses such as GP and scleral designs, formulation strategy becomes increasingly relevant.
