Abstract Details

Purpose:

To compare anterior segment parameters and corneal densitometry in patients with keratoconus who underwent penetrating keratoplasty (PK) in one eye and no corneal surgery in the fellow eye.

Setting:

Cornea Service, Wills Eye Hospital, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, USA

Methods:

This study was conducted on 30 eyes of 15 patients with keratoconus who underwent PK in one eye at least one year ago (PK group) and no corneal surgery in the fellow eye (control group). The mean age was 52.6±14.5 years. Each eye was analyzed with the anterior segment optical coherence tomography and Scheimpflug imaging systems. Data were compared between two groups.

Results:

There were no statistically significant differences in the anterior chamber (AC) angle opening distance (AOD) 500, AOD750, trabecular iris space area (TISA) 500, TISA750, scleral spur angle values in 180 and 0 degree meridians measured by AS-OCT between groups (p>0.05). The CCT value was statistically significantly higher in the PK group than the control (p˂0.001). The Sim K value in the PK group was statistically significantly lower than the control (p=0.039). There were no statistically significant differences in the all of corneal densities, AC depth, corneal volume, and AC volume values measured by Scheimpflug imaging (p>0.05).

Conclusions:

Although PK surgery does not affect the anterior chamber angle parameters, anterior chamber volume, corneal volume, and corneal density values; it increases the mean central corneal and thinnest corneal thickness values, and decreases the mean Sim K value.
