Singh G. A new eye stand. Indian J Ophthalmol 1973;21:28-9
A proper cutting of corneal graft from donor eye necessitates its proper placement in order to hold it steady in a fixed position. Various methods of holding the donor eyes have been described. PATON  described the method of holding the eye ball in muslin gauze. TUDOR THOMAS  used a stand for fixation of donor eye by passing a suture through optic nerve. LEIGH  however has mentioned the use of Luntz's modification of Tudor Thomas stand which overcomes to some extent the effect of eccentricity of the optic nerve and can be rotated.
A new Eye Stand
The eye stand has a weight of 500 gms. It has two detachable parts and is made up of an alloy of coper.
I. Base [Figure - 1]: It is quite broad and round. The diameter of the base is 4 inches. At the top, the base has a diameter of 2 inches. It has threads for screwing the top over it. in the centre of the base is a through and through hole 15 mm in diameter reaching the top and expanding in such a way as to hold the globe.
If. Top [Figure - 2],[Figure - 3] : It is a separate attachment. It has a central hole which is 15 mm in diameter. This can be easily screwed over the base.
| Comments|| |
The new eye stand has many advantages over the existing ones.
(i) There is no need to pass a stitch through the optic nerve for fixation.
(ii) There is no eccentricity of the cornea as the globe does not get tilted to any side during cutting of graft.
(iii) Adequate pressure can be applied over the donor eye easily by screwing or unscrewing the top.
(iv) The central hole exposes only the central part of cornea and rim of sclera, hence less chances of infection by touching the donor tissue.
(v) There is no need of an assistant during cutting of graft from a donor eye.
| Summary|| |
A new eye stand for holding and fixing the donor eye is described giving its merits over existing procedures.
