Purpopse:
This study aims to evaluate the ocular surface response after strabismus surgery, using two different materials for conjunctival closure.
Methods:
Randomized prospective comparative study was done. After performing strabismus surgery, conjunctival flap was apposed with fibrin sealant in Group 1 and 8-0 vicryl suture with buried knots in Group 2. Preoperative and postoperative measurement of tear film break up time and Schirmer test for tear secretion was done in both the groups of 30 patients each at regular follow-up visit up to 2 months. Postoperatively, both the groups were also compared for the resolution of discomfort and redness.
Results:
Conjunctival recession was not seen in any group. Mean period was 5.8 days for resolution of discomfort (pain, lacrimation, and irritation) and 7.2 days for redness in Group 1 compared to 12 and 16 days in Group 2 (P < 0.05). During the study, we noticed significant decrease in tear film stability and increase in tear secretion in both the groups. However, in Group 2, the parameters were significantly more altered and even changes persisted for longer duration.
Conclusion:
Early rehabilitation of ocular surface might be related to unaltered healing process with the use of a biological substance (fibrin sealant) as compared to suture.
