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 three-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 it is practical and effective in the real world.
