Evaluation of post-operative dry eye in upper and lower eyelid reconstruction: A cross-sectional study

PURPOSE: In cases of eyelid malignancies requiring full thickness excisional biopsy followed by reconstruction of the created defect, the Meibomian glands are lost. Post-operative varying degrees of dry eye disease (DED) are expected in such patients. The aim was to evaluate the objective and subjective statuses of DED in cases of full thickness eyelid reconstruction following excisional biopsy because of malignancies. METHODS: This was a cross-sectional pilot study. Objective and subjective dry eye parameters are assessed in cases of full thickness eyelid reconstruction following excisional biopsy because of malignancies in 37 eyes at 6 months post-operative follow-up. Analysis of variance and Chi square test were used for statistical analysis. RESULTS: When compared with fellow eye, all the parameters were found to be statistically significant (P < 0.0). Subjective assessment of dry eye by ocular surface disease index (OSDI) scoring did not corroborate with the objective data (p 0.00). Lower eyelid reconstruction showed a minimum number of dry eye cases (P > 0.05). CONCLUSION: Prevalence of post-operative dry eye is more with increasing percentage of full thickness upper eyelid reconstruction. Disparity was found between objective and subjective parameters of dry eye in patients requiring varying percentages of upper eyelid reconstruction because of malignancies.
