Abstract Details


To assess the wound healing patterns in femtosecond assisted deep anterior lamellar keratoplasty.


Vissum Corporación Alicante, Universidad Miguel Hernández, Alicante, Spain.


50 eyes had performed deep anterior lamellar keratoplasty (DALK), 25 eyes were femtosecond assisted either mushroom or super mushroom configuration and the other 25 eyes were performed manually with suction trephine (control group). Big bubble technique was performed in all eyes and in some eyes dissection was completed manually due to failure of big bubble. The patients were followed for 12 months after surgery. Wound healing pattern in both groups were evaluated at the end of the 12 months follow up using slit lamp and Visante anterior segement OCT. We made an original classification for wound healing patterns in keratoplasty. According to our original classification, healing pattern was graded into: grade 0 transparent scar or minimal healing opacity, grade 1 faint healing opacity, grade 2 evident healing opacity, grade 3 Healing opacity as a continuous scar (circular) or in 2 quadrants with moderate cosmetic imbalance and grade 4 Healing opacity with high cosmetic imbalance and scarring through sutures.


Results showed that 55% of femtosecond assisted DALK cases with wound healing patterns grade 3 and 4 while only 20% of manual DALK cases showed the same grades of wound healing patterns.


Femtosecond assisted DALK showed more active wound healing leading to leucomatous wound either due to larger area of contact between donor and recipient or due to femtosecond activation of biological activity FINANCIAL INTEREST: NONE
