This chapter reviews the surgical indications basic instrumentation surgical techniques and complications associated with suturing techniques in vitrectomy and scleral buckle surgery. A brief discussion of future advances in retinal surgery appears at the end of this chapter. Surgical Indications Vitrectomy Typically there are three indications for suturing during vitrectomy surgery placement of the infusion cannula closure of sclerotomy and the conjunctival closure. A variety of ancillary suturing techniques may be employed during vitrectomy including the external securing of a lens ring for contact lens visualization placement of transconjunctival or .
