Scleral fixation without conjunctival dissection

Scleral fixation of intraocular lenses (IOLs) and adjunctive capsular devices can be performed under the protection of a scleral flap. A modification of this technique uses a scleral pocket initiated through a peripheral clear corneal incision. Full-thickness passage of a double-armed suture through the scleral pocket and conjunctiva, with subsequent retrieval of the suture ends through the external incision for tying, facilitates scleral fixation. This modification offers several advantages over traditional methods: It eliminates the need for conjunctival dissection and scleral cauterization; a scleral pocket affords a greater surface area for suture placement through an ab externo or ab interno approach; retrieval of the sutures through the external corneal incision and subsequent tying allows the suture knot to pass under the protective roof of the scleral pocket, negating the need for suture knot rotation; and the architecture of the scleral pocket eliminates the need for sutured wound closure. Suture retrieval and scleral fixation through a corneoscleral pocket offers a refined method for fixation of IOLs and other intraocular adjunctive devices.
