Animals were randomized to one of two groups (18 per group): the suture group or RB\u2010PCL group. Photochemical crosslinking with a wavelength of 532\u2009nm green light with an illumination intensity of 0.6\u2009W\/cm<jats:sup>2<\/jats:sup> for 250\u2009seconds (150\u2009J\/cm<jats:sup>2<\/jats:sup>) or suturing was performed followed by light examination at 3, 7, 28 days after surgery to evaluate the healing condition. Rabbits in each group were euthanized on day 3 (<jats:italic>n<\/jats:italic>\u2009=\u20096), 7 (<jats:italic>n<\/jats:italic>\u2009=\u20096), or 28 (<jats:italic>n<\/jats:italic>\u2009=\u20096) postoperatively, and the graft tissues from the surgical site were processed to evaluate inflammatory response by assessing protein levels of tumor necrosis factor \u03b1 (TNF\u2010\u03b1), and interleukin 6 (IL\u20106)\u00a0as well as histological examination. Cell viability was evaluated by counting both total and dead cells on hematoxylin and eosin (H&amp;E) stained tissue samples from both groups at 3 and 7 days after surgery. The surgery procedure time was recorded and the graft surface temperatures were measured before and after illumination.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Photochemical crosslinking effectively secured the limbal conjunctival autograft over an ocular conjunctival defect with no significant difference from the suture group. The time required for this light activated bonding method was ~550\u2009seconds in comparison with the suture method of half hour. The differences of measured temperature on the graft surface before and after RB\u2010PCL treatment were 2.98\u2009\u00b1\u20090.11\u00b0C. The induction of IL\u20106 and TNF\u2010\u03b1 protein was remarkably reduced in the RB\u2010PCL group compared with the suture group at 3 and 7 days after surgery. Histology revealed less infiltrated neutrophils were observed in the RB\u2010PCL group than in the suture group at 3 and 7 days postoperatively. Furthermore, the RB\u2010PCL group showed a better healing process with less eye discharge and mild conjunctival congestion. No significant difference in percent dead cells was observed between RB\u2010PCL and suture groups at 3 and 7 days after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>RB\u2010PCL is a promising alternative for bonding the conjunctival autograft with shorter operation time, less inflammation and better healing outcomes compared to conventional suture.
