Eye positioning and fixation device during ophthalmic surgery

Abstract

An ophthalmic surgical device for positioning and fixing the eye using a traction suture or multiple traction sutures, comprising: a base configured to be fixed to a periorbital region including the lower periorbital region and the frontotemporal region, the base having an adhesive surface for adhesion to the periorbital region; the base including an anchor element for adjustable fixation of the traction suture or multiple traction sutures; the base having a support edge on the lateral side of the eyelid for contacting and supporting at least a portion of the eyelid supported by a retractor, or at least a portion of an eyelid retractor for opening the eyelid. The anchor element may include a recess for the passage of the suture or multiple sutures and for holding the suture or multiple sutures. The anchor element may include a rotatable fastener for fixing the suture or multiple sutures. The rotatable fastener may be rotatably coupled to the anchor element.

8. An ophthalmic surgical device for positioning and fixing the eye according to any of the preceding claims, wherein the base further includes a raised groove for providing friction to the suture or a plurality of sutures and lifting the suture or a plurality of sutures away from the base toward the suture path in the anchor element or the fastener, if such an anchor element or fastener is present.

9. An ophthalmic surgical device for positioning and fixing the eye according to any of the preceding claims, wherein the base further includes, between the support edge and the anchor element, the support edge itself and one or more projections for deflecting one or more sutures.

10. An ophthalmic surgical device for positioning and fixing the eye according to any of the preceding claims, wherein the base has a curve, or a curve and a reverse curve, for contouring adjacent to the periorbital region.

11. An ophthalmic surgical device for positioning and fixing the eye according to any of the above claims, wherein the base is an elongated base having two ends.

12. An ophthalmic surgical device for positioning and fixing the eye according to the preceding claim, wherein the base has a constricted portion between a first end and a second end.

13. An ophthalmic surgical device for positioning and fixing the eye according to the preceding and second claims, wherein the two laterally protruding tabs are positioned on the constricted region of the base.

14. An ophthalmic surgical device for positioning and fixing the eye according to any of the above claims, wherein the anchor element is a protruding anchor.

15. An ophthalmic surgical device for positioning and fixing the eye as described in the preceding claim, comprising a fastener having a corresponding hollow volume for coupling with the protruding anchor, which coupling with the protruding anchor for fixing the suture or a plurality of sutures, and in particular being shaped to fix at least two sutures fixed in opposite sliding directions to reduce the sliding of the sutures.

16. An ophthalmic surgical device for positioning and fixing the eye according to any of the above claims, wherein the anchor element is an anchor having a hollow volume for passing and fixing the traction suture or a plurality of traction sutures.
