A microkeratome cutting head 10 includes a body (12) for securing a cornea cutting element (32) and presents a leading cornea engaging portion (18, 20, 22). The leading cornea engaging portion (18) is tapered so that in operation the cutting head (10) gradually compresses a cornea (30) and thus minimizes epithelial damage to the cornea (30). |
