Abstract

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. In an exemplary implementation, an ophthalmic surgical system includes a patch sized and shaped to seal a retinal break of an eye by preventing fluid from infiltrating a sub-retinal space when adhered to the retina surrounding the retinal break; and a delivery device including a cannula configured to maintain the patch in a furled state for passage through an incision in the eye, the delivery device actuatable to deploy the patch within a vitreous chamber of the eye. In another exemplary implementation, an ophthalmic surgical method includes damaging tissue around a retinal break; delivering, into the vitreous chamber, a patch sized and shaped to seal the retinal break; positioning the patch on the retina surrounding the retinal break; and affixing the patch to the retina such that the patch prevents fluid from infiltrating a sub-retinal space.

Claims

1. An ophthalmic surgical system, comprising:

a patch sized and shaped to seal a retinal break of an eye by preventing fluid from infiltrating a sub-retinal space when adhered to the retina surrounding the retinal break; and

a delivery device including a cannula configured to maintain the patch in a furled state for passage through an incision in the eye, the delivery device actuatable to deploy the patch within a vitreous chamber of the eye.

2. The system of claim 1, wherein the patch comprises at least one of a hydrogel, a biological material, an elastomeric polymer, a cross-linking agent, or a curing agent.

3. The system of claim 1, further comprising an adhesive configured to affix the patch to the retina.

4. The system of claim 3, wherein the adhesive is disposed on the patch.

5. The system of claim 4, wherein the adhesive is activated upon exposure to liquid.

6. The system of claim 4, wherein the adhesive is activated upon exposure to light.

7. The system of claim 3, further comprising an applicator sized and shaped for insertion into the vitreous chamber, the applicator configured to apply the adhesive to at least a perimeter of the patch while the patch is positioned on the retina.

8. The system of claim 1, wherein the delivery device further comprises a body coupled to the cannula, the body being sized and shaped for grasping by a user.

9. The system of claim 8, wherein delivery device includes a shaft movably disposed within the cannula, the shaft configured to eject the patch from the cannula upon movement of the shaft.

10. The system of claim 9, wherein the shaft is coupled to an actuation control controlling movement of the shaft.

11. The system of claim 10, wherein the actuation control is disposed on the body of the delivery device.

12. An ophthalmic surgical system, comprising:

a delivery device comprising a body, a cannula coupled to the body, and a shaft movably disposed within the cannula, the cannula being sized and shaped to be inserted into a vitreous chamber of the eye; and

a patch sized and shaped to seal a retinal break when adhered to the retina surrounding the retinal break, wherein the patch is disposed within the cannula in a furled state, and wherein, upon actuation of the shaft, the patch is ejected from the cannula into the vitreous chamber, the patch being adjustable to an unfurled state.

13. The system of claim 12, further comprising an adhesive configured to affix to the patch to the retina.

14. An ophthalmic surgical method, comprising:

damaging tissue around a retinal break of an eye;

delivering, into the vitreous chamber of the eye, a patch sized and shaped to seal the retinal break;

positioning the patch on the retina surrounding the retinal break; and

affixing the patch to the retina such that the patch prevents fluid from infiltrating a sub-retinal space.

15. The method of claim 14, further comprising obtaining a delivery device including the patch in a furled state, wherein delivering the patch includes ejecting the patch from the delivery device in an unfurled state.

16. The method of claim 14, wherein delivering the patch includes actuating a shaft of a delivery device, the delivery device including a body, a cannula coupled to the body, and the shaft movably disposed within the cannula, the cannula being sized and shaped to be inserted into the vitreous chamber, wherein actuating the shaft ejects the patch from the cannula.

17. The method of claim 14, wherein affixing the patch to the retina includes applying an adhesive around a perimeter of the patch.

18. The method of claim 14, wherein affixing the patch to the retina includes activating an adhesive disposed on the patch.

19. The method of claim 18, wherein activating the adhesive includes exposing the adhesive to a liquid.

20. The method of claim 18, wherein activating the adhesive includes exposing the adhesive to light.
