What occurs in the corneal stroma as part of the healing process?

During the healing process of the corneal stroma, keratocytes play a crucial role. When the cornea is injured, keratocytes, which are specialized cells within the stroma, become activated. They transform into fibroblast-like cells that exhibit contractile properties. This transformation helps to facilitate wound healing by producing extracellular matrix components, including collagen, that are essential for restoring the structural integrity of the cornea.

The first option is correct because the transformation of keratocytes into contractile cells aids in the repair process, contributing to collagen remodeling and aiding in the contraction of the wound site, which is vital for efficient healing.

Additionally, while other options may contain elements of truth regarding corneal healing processes, they do not accurately capture the specific changes occurring in the stroma during healing. For instance, the stroma is known to heal relatively slowly and can involve scarring, which is not addressed in the options that suggest rapid healing without scarring or the fixed rate of epithelial growth. The organization of the collagen structure typically becomes less organized in the initial phases of healing before it eventually becomes more organized over time. Thus, while these points about healing are relevant, they do not directly reflect the significant role of keratocyte transformation in the healing
