Corneal epithelial pocket formation systems include a cutting head and a blade coupled to the cutting head. The blade is coupled to the cutting head at an orientation that is effective in maintaining a viable separated pocket defining portion of corneal epithelium of an eye of a patient during formation of a corneal epithelial pocket of the eye. The blade includes a cutting edge surface at its distal end. The cutting edge surface is effective in separating the corneal epithelium from the underlying Bowmans membrane of the eye without leaving residual corneal epithelial cells in contact with Bowmans membrane that may result in corneal epithelial cell growth between a corneal implant located in the corneal epithelial pocket and the underlying Bowmans membrane. Versions of the present systems include spring loaded blade holders, which may be removable from the cutting head. Versions also can include applanators. Packages containing spring loaded blade holders and blades, and disposable blades useful with the present systems are also described. The components, including disposable components, can be used to produce the present systems, and the present systems and components can be used in methods of enhancing or correcting a patients vision.角膜上皮囊形成系統包括一個切割頭和一個接至該切割頭之刀片,刀片乃連接至切割頭,其方位能有效地使界定了一部份患者眼睛角膜上皮之已分離囊在眼睛角膜上皮囊形成期間繼續存活。刀片於其遠端處含有一個切割邊緣表面,切割邊緣表面可有效地將角膜上皮和眼睛下面的鮑曼氏膜分開,不會殘留角膜上皮細胞與鮑曼氏膜接觸,其可能導致角膜上皮細胞在角膜上皮囊中的一個角膜植入物與下面的鮑曼氏膜之間生長。本系統之版本包括彈簧裝載式刀座,其可從切割頭取出。版本亦可包括若干壓平器。套件包含了彈簧裝載式刀座及刀片,亦敘述了與本系統一起使用之可拋棄式刀片。組件包含了可拋棄式組件,其可用以形成本系統,且本系統及組件可用於增進或矯正患者視力的方法中。10...角膜上皮囊形成系統12...殼體14...推進馬達纜線16...擺動馬達纜線20...切割頭22...鎖定裝置24...接頭構件26...刀座28...吸力環30...真空接頭32...驅動栓
