When should therapeutic soft lenses be fit with minimal movement?

Therapeutic soft lenses are specifically designed for managing various eye conditions, and the fitting characteristics can differ based on the specific issue being treated. In the case of recurrent erosion, these lenses should be fit with minimal movement to ensure maximum comfort and protection of the cornea.

Minimal lens movement is essential in this scenario because any movement can irritate the already compromised epithelial layer and potentially disrupt the healing process. By reducing movement, the lens can provide a stable covering over the cornea, delivering a protective barrier while also allowing for the retention of moisture and promoting healing. This is particularly critical in patients who experience recurrent episodes of corneal erosion, as their corneas are sensitive and require careful management.

Other conditions listed, like corneal abrasion or dry eye syndrome, may have different requirements for lens movement. For example, in corneal abrasion management, some movement may allow the lens to redistribute tears to maintain moisture and promote healing. Meanwhile, patients with dry eye syndrome might benefit from lenses that are designed to retain more moisture but don't necessarily require the same degree of stability as in recurrent erosion cases. Astigmatism correction typically focuses on lens fit to achieve visual acuity without specific regard to the level of movement. Therefore, fitting therapeutic soft lenses with minimal
