Four cases of conjunctival squamous carcinoma invading the cornea are presented. The surgical technique of excising the tumours from the cornea by lamellar keratectomy is described. Histology of the lesions showed well differentiated squamous carcinoma invading the superficial layers of the cornea only. Large invasive squamous cell carcinomas of the cornea result because of neglect of small par...

By comparing the composition of McCarey-Kaufman (MK) medium before and after corneal storage we attempted to identify specific physiological changes in the medium as predictors of tissue damage. We also tried to determine if hydrocortisone (a lysosomal membrane stabiliser) added to the medium could reduce tissue damage during storage. Corneas (human and rabbit) were stored in the MK medium with...
