6 Months Post Cataract Surgery Examination 

Both of this dog's eyes did very well, but at the 6-months check post phacoemulsification, the right eye was causing minor bother to the dog and a pigmented swelling had developed ventromedially below the Nictitans membrane. A presumed diagnosis of benign limbal melanoma was made and we decided to proceed to surgery. A lamellar excisional biopsy was done, followed by a double freeze-thaw cycle of cryosurgery according to the protocol described by Featherstone et al Vet Ophthal 2009 Nov-Dec; 12 Suppl 1: 65-72 (Efficacy of lamellar resection, cryotherapy and adjunctive grafting for the treatment of canine limbal melanoma). 

The limbal melanoma

The limbal melanoma can be seen extending into the cornea and causing gross thickening and distortion of the normal corneal curvature.
