Abstract Details


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.


Kartal Training and Research Hospital


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.


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).


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.
