Abstract Details

Purpose:

To evaluate the effect of the corneal changes following Cross-linking(CXL) on the anterior chamber in keratoconus patients by using the pentacam.

Setting:

Inonu Universty

Methods:

22 eyes of 22 patients who had been diagnosed with progressive keratoconus and had undergone CXL. The preoperative, postoperative 6th month and postoperative 1st year best corrected visual acuity results using the Snellen chart, flat meridian of the anterior corneal surface (K1), steep meridian of the anterior corneal surface (K2), mean anterior corneal curvature (Km), thinnest corneal thickness (TCT), corneal volume (CV), anterior chamber volume (ACV), anterior chamber angle (ACA) and anterior chamber depth (ACD) Scheimpflug imaging values were obtained for each eye.

Results:

TCT decreased in the postoperative 6th month but the difference was not statistically significant (p= 0.071). However, there was a statistically significant increase at the postoperative 1st year (p˂ 0.05). CV showed a statistically significant decrease on the postoperative 6th month (p= 0.031), but there was a statistically significant increase on the postoperative 1st year (p˂ 0.05). ACV, ACA and ACD were stable at the postoperative 6th month (p˃ 0.05) but there was a statistically significant decrease at the postoperative 1st year (p˂ 0.05).

Conclusions:

Cross-linking has an improving effect on the cornea and on the anterior chamber. This effect becomes marked especially at the postoperative 1st year evaluation. FINANCIAL DISCLOUSRE: NONE
