To evaluate the wound-healing changes in clear corneal cataract incisions (CCIs) and the duration of stromal edema caused by intentional hydration in cataract surgery using anterior segment optical coherence tomography (OCT).
Mohamed Tahar Mâamouri Hospital, Department of Ophtalmology, Faculty of Medicine of Tunis, Nabeul, Tunisia
Randomized prospective study including 50 eyes who underwent phacoemulsification cataract surgery performed by two experienced surgeons. All CCIs had a similar arcuate architecture with 2,20 mm disposable metal keratome. Half the CCIs had stromal hydration with a balanced salt solution and half did not. Each patient underwent an OCT postoperatively at day 1, 7 and 30. The angle of incision and corneal thickness at the CCI were measured. The architecture was described according to the apposition of the epithelial and endothelial margins, wound sealing and the presence of Descemet membrane detachment.
In our preliminary results no leakage was detected. The angle varied from 35 to 75 degrees. There was difference in corneal thickness at CCIs between eyes with and without stromal hydration 1 day and 1 week after surgery but not at 1 month after surgery. Wound apposition at the epithelial margin was achieved in all cases. We observed greater frequency of endothelial gaping and local detachment of descemet membrane in hydrated group
Anterior segment OCT provides sensitive and detailed measurements of the ultrastructures in CCIs and the persistent of stromal swelling from stromal hydratation on the first postoperative week, which, according to many studies of CCI disappeared within four hours.
