Abstract Details

Purpose:

This study was conducted to compare the visual outcomes and complications after deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PKP) in the contralateral eyes of the same patients.

Setting:

Kartal Training and Research Hospital

Methods:

A retrospective cohort study was undertaken at the Kartal Training and Research Hospital. We reviewed the records of 26 patients (52 eyes) who underwent DALK in 1 eye and PKP in their fellow eye between 2005 and 2012. Penetrating keratoplasty was performed with a standard technique using a Hessburg-Barron trephine. The DALK procedures were performed according to the Anwar and Teichmann big-bubble technique.Visual acuity, refractive status, endothelial cell (EC) loss , intraocular pressure (İOP) and complications were evaluated to compare these techniques.

Results:

The mean postoperative BCVA was 0.19±0.16 and 0.15±0.11 respectively (p=0.274).There was no significant differences in the best-corrected visual acuity and refractive error between the DALK-operated and PK-operated eyes throughout the follow-up period. The mean postoperative refractive astigmatism was −3.36±2.40 diopters (D) in the DALK-operated eyes versus −3.50±2.70 D in the PK-operated eyes (p=0.844). EC density was significantly higher after DALK compared with PK at 24 months postoperative (1899.5±287.4 vs. 1672±388.8 p=0.022). The İOP at 24 months after surgery were 13.9±2.4mmHg in the PK operated eyes and 14.0±2.3mmHg in the DALK operated eyes. The İOP was not significantly different in the DALK group than in the PK group at 24 months postoperatively (p=0.878).

Conclusions:

Deep anterior lamellar keratoplasty surgery using the big-bubble technique provides good final visual and refractive outcomes with a clearer interface and thus can be considered a reasonable alternative to PKP.
