The present invention provides an improved surgical blade and trocar system for accessing the retina and other parts of the eye while doing vitreo-retinal and cataract surgeries, including surgeries for macular degeneration. The eye surgeon uses an improved surgical blade for vitreo-retinal and cataract surgeries having a generally flat, V-shaped, W-shaped, or “extended W” shaped cross-section. Using the improved surgical blade, the surgeon creates a multi-planar, self-sealing surgical wound, first by directing the surgical blade substantially perpendicular to the eye surface, then redirecting the blade to follow the general curvature of the eye globe, and finally redirecting the blade to enter the interior of the eye. The improved surgical blade is used with an improved trocar system having two main parts-a relatively rigid, wide-mouthed outer segment and a generally thin-walled, collapsible plastic polymer or metal mesh sleeve that spans the surgical wound and substantially molds to its contour. The improved surgical blade and trocar system can be adapted for use in either vitreo-retinal or cataract surgeries.
