Sutureless and Equipment-free Technique for Contact Lens Viewing System during Vitreoretinal Surgery.

PURPOSE To report a sutureless and equipment-free technique for contact lens wide-angle viewing system during vitreoretinal surgery. METHODS A step-by-step procedure and a surgical video using this technique were proposed. RESULTS This technique needs only 3-finger control of contact lens either by the left hand (for the right-handed surgeon) or right hand (for the left-handed surgeon). The contact lens is not fixed to the environment (lid speculums, cannulas, corneoscleral limbus), therefore it allows the surgeon to move and tilt the contact lens freely while keeping a clear view of the retina. CONCLUSION The sutureless and equipment-free technique for contact lens viewing system during vitreoretinal surgery has been tried and tested, and is practical and effective in the real world.
