Abstract Details

Purpose:

To examine the effect of Descemet’s (D’s) membrane exposure during deep anterior lamellar keratoplasty (DALK) on postoperative visual outcomes.

Setting:

Inouye Eye Hospital and University of Tokyo.

Methods:

The subjects were 19 eyes in 17 cases (mean age; 58.8±16.6 year old) in which DALK was performed. In all cases, big bubble technique was used first. When big bubble was not formed, layer by layer technique was used.

Results:

Best-corrected visual acuity (BCVA) in LogMAR in 15 eyes with intraoperative D’s membrane exposure, at preoperation and 6, 12, 24 months postoperation, was 0.81±0.30, 0.23±0.27, 0.12±0.13, and 0.08±0.15, respectively. BCVA in LogMAR in 4 eyes without D’s membrane exposure, at preoperation and 6, 12, 24 months postoperation, was 0.89±0.68, 0.73±0.19, 0.77±0.28, and 0.61±0.30, respectively. At all postoperative points, BCVA was significantly better in eyes with D’s membrane exposure than that in eyes without D’s membrane exposure (p < .05).

Conclusions:

Intraoperative D’s membrane exposure during DALK improves postoperative visual function.
