Abstract Details
Purpose:
To Evaluate the result of Femto DLEK in cases of Congenital Hereditary Endothelial Dystrophty
Setting:
INTERNATIONAL EYE HOSPITAL CAIRO EGYPT
Methods:
This study included 10 eyes of children with corneal opacity due to congenital hereditary endothelial dystrophy . The age of the children ranged from 3 to 9 years. All children had severe corneal opacity with corneal thickness more 950-1300 um. The treatment goal was to remove the posterior lamellae of the diseased cornea (endothelium and posterior stroma ) using femtosecond laser and to replace the removed part by ultrathin DSEAK graft. .All cases was performed under general anaesthesia. Main outcome measures were examination of the graft , BCVA and corneal thickness by anterior segment OCT
Results:
All cases has clear graft with graft thickness ranging from 110-180 um .FS-DLEK was effective in treating endothelial failure, with minimal change in refractive astigmatism and mild hyperopic shift in refraction. Although it has many advantages over the penetrating keratoplasty , DLEK in the pediatric population is very challenging. Due to some technical difficulties as the difficulty of separation of the tissue , anterior chamber tends to be smaller and shallower in pediatric eyes which make it harder to avoid lenticular injury during surgery. Additionally, the supine position required in the immediate postoperative is often difficult for children to maintain.
Conclusions:
Femto assissted DLEK is an effective and safe technique in CHED . It allows early replacement of the opacified cornea with minimal problems of PKPs. It allows for a faster postoperative recovery, with earlier initiation of amblyopia treatment Additionally, DSAEK decreases the risks associated with open-sky techniques , the risk of infection and suture-related problems .
