SURGERY OF THE OCULAR SURFACE

摘要

It is important to have the correct instrumentation for handling the corneal tissuesMagnification and good illumination is requiredA knowledge of corneal physiology and healing is neededHaving the correct surgical instruments is very important. A kit may include instruments suitable for handling the eyelids such as eyelid specula, forceps, scissors and needle-holders that are suitable for handling the fine eyelid skin. These will be finer than the general skin instruments but not as fine as those used for handling the cornea itself. Expensive corneal surgical instruments will be ruined if they are used to handle eyelid skin. Instruments for handling conjunctiva are also required. Forceps might include St Martin's suturing forceps or Bishop-Harman forceps. Scissors suitable include blunt tipped tenotomy scissors. For handling corneal tissue corneal forceps should be used to allow atraumatic tissue handling. A suitable pair is .12 Castroviejo corneal forceps or Colibri forceps.
