Abstract Details

Purpose:

To investigate the differences between alcohol (AD) and mechanical delamination (MD) in the treatment of keratoconus with corneal cross- linking (CXL).

Setting:

Retrospective review of consecutive single-surgeon series of CXL at the Southampton University Hospital

Methods:

We used pre- operative and post- operative Pentacam data of patients having CXL for keratoconus. More specificaly we extracted K1, K2, Kmax, Minimum corneal thickness and the corneal densitometry of the anterior 0-2mm, anterior 2-6mm, central 0-2mm, central 2-6mm.

Results:

We identified 28 patients (mean age 26.3) that had AD from June 2016 and December 2017 and compare them with 28 consecutive patients (mean age 27.0) that had MD. All preoperative data had no statistical significant difference between the two group (p>0.05, two-tailed unpaired t test). The differences of the values before and after the operation were not statistical different between the two groups with the exception of the corneal densitometry of the central 2-6mm. More specifically the median increase of density was 1.05μm for the AD and 2.80 for the MD group (p=0.0082, two-tailed unpaired t test).

Conclusions:

Mechanical delamination appears to results in a significantly bigger corneal densitometry of the Central 2-6mm after CXL comparing to alcohol delamination. This might result to more reported haze after the operation.
