ABSTRACT
OBJECTIVES: To report the outcomes following the insertion of a rhexis-fixated prosthetic intraocular lens (IOL) in dogs undergoing lens removal. MATERIALS AND METHODS: The results are from 30 eyes of 28 dogs, undergoing lendectomy, in which the lens capsule could not accommodate a conventional prosthetic endo-capsular IOL. The reported cases had sustained either spontaneous or traumatic lens capsule rupture, or accidental intra-operative iatrogenic lens capsule disruption, or had required a planned, large, anterior or posterior continuous curvilinear capsulorhexis, all of which precluded insertion of a prosthetic IOL within the lens capsule. An acrylic IOL (XVET; Medicontur) was modified and positioned across the anterior and/or posterior capsulorhexes. RESULTS: Other than haptic luxation in three cases, no complications were seen that were directly attributable to the rhexis-fixated lens. Over a follow-up period from three to 76 months (mean 20.7 months) 26/30 eyes remained visual. Blindness developed in three eyes due to retinal detachment and one eye was enucleated due to regrowth of a ciliary body adenoma. CLINICAL SIGNIFICANCE: Rhexis fixation provided an alternative method to implant a prosthetic IOL when the lens capsule was unable to accommodate a conventional endo-capsular IOL.

Extensive skin loss from the forelimb of a Border collie was repaired by a microvascular caudal superficial epigastric flap, with secondary meshing of the flap to increase coverage. The caudal superficial epigastric artery and vein were anastomosed to the brachial artery and vein. End-to-end anastomosis to the brachial artery and vein did not compromise peripheral blood flow, and no flap necrosis was observed after subsequent limited meshing of the flap.

Porcine small intestinal submucosa (SIS) was used, in conjunction with a conjunctival graft, to repair a full thickness corneoscleral defect resulting from the excision of a limbal melanoma in a German shepherd dog. The SIS was found to provide adequate mechanical support and to act as a suitable physical barrier in place of the excised cornea and sclera. Corneal vascularisation was present distant to the graft by two weeks postoperatively but this was effectively controlled with topical cyclosporin. By six weeks postoperatively, the graft had become incorporated into the cornea and sclera, and the associated corneal neovascularisation had resolved. From this initial case, porcine SIS would appear to be a suitable material for the repair of corneoscleral defects in dogs.
