Abstract Details

Purpose:

To evaluate the clinical findings, refractive and visual results of deep anterior lamellar keratoplasty (DALK) techniques in keratoconus: Big-bubble versus manual dissection

Setting:

Beyoglu Eye Training and Research Hospital

Methods:

Fifty-eight eyes of 51 patients with severe keratoconus were treated with one of the two surgical techniques manual DALK (n = 24); big-bubble DALK (n = 34). The main outcomes measured were visual acuity, refractive status, corneal topographic parameters, corneal thickness and endothelial cell density (ECD). Patients were examined postoperatively at 6 months, 12 months and 6 month after suture removal.

Results:

Mean age was similar in both groups.After surgery, visual acuity improved significantly in both groups.Postoperative ECD was similar in both groups at all intervals, with no statistically significant differences

Conclusions:

Manual dissection and big-bubble techniques in DALK were similar visual results. Big bubble technical implementation of the integrity of the descement membrane layer was considered to be safer.
