I think it's definitely worth a shot IMO based on what I understood from those studies, unfortunately, I wasn't able to find a direct paper relating to your case.
"Tβ4 may provide a new clinical treatment for severe traumatic corneal wound disorders by promoting rapid corneal wound healing and decreasing both PMN infiltration and inflammatory cytokine and chemokine mRNA levels."
- Sosne, G., Szliter, E. A., Barrett, R., Kernacki, K. A., Kleinman, H., & Hazlett, L.
D.(2002). Thymosin beta 4 promotes corneal wound healing and decreases
inflammation in vivo following alkali injury. Experimental eye research, 74(2),
293-299.
"These results provide the first direct evidence that T beta 4 has chemoattractive activity and promotes angiogenesis by stimulating the migration of endothelial cells."
-Malinda, K. M., Goldstein, A. L., & Kleinman, H. K. (1997). Thymosin beta 4
stimulates directional migration of human umbilical vein endothelial cells. The
FASEB journal, 11(6), 474-481.
"Increased collagen deposition and angiogenesis were observed in the treated wounds. We also found that Tbeta4 stimulated keratinocyte migration in the Boyden chamber assay. After 4–5 h, migration was stimulated 2–3-fold over migration with medium alone when as little as 10 pg of Tbeta4 was added to the assay. These results suggest that Tbeta4 is a potent wound healing factor with multiple activities that may be useful in the clinic."

investigative dermatology, 113(3), 364-368.
