Abstract Details

Purpose:

The aim of the study was to compare anterior and posterior corneal surface evaluation after DALK to PK) in patients who underwent corneal transplant due to keratoconus.

Setting:

Ophthalmology Department of Trauma Centre in Sosnowiec, Silesia, Poland.

Methods:

50 patents (50 eyes) who underwent DALK and 35 patients( 40 eyes) who underwent PK (65 male and 25 female eyes) with mean age of 34.3 ± 11.6 years were evaluated. Anterior and posterior corneal elevations were measured using topographic analysis (using a rotating Scheimpflug camera), and the imaging data were analyzed to estimate elevation differences as differential values from conventional best-fit-sphere and enhanced best-fit-sphere (exclusion of a 4-mm-diameter area from the most thinned cornea). Patients were examined twice one year and five years after the surgery.

Results:

50 patents (50 eyes) who underwent DALK and 35 patients( 40 eyes) who underwent PK (65 male and 25 female eyes) with mean age of 34.3 ± 11.6 years were evaluated. Anterior and posterior corneal elevations were measured using topographic analysis (using a rotating Scheimpflug camera), and the imaging data were analyzed to estimate elevation differences as differential values from conventional best-fit-sphere and enhanced best-fit-sphere (exclusion of a 4-mm-diameter area from the most thinned cornea). Patients were examined twice one year and five years after the surgery.

Conclusions:

Posterior corneal elevation was stable in both groups however anterior corneal elevation was more stable after PK when compared to DALK.
