Corneal Changes After Crosslinking in Keratoconus Patients Compared to the Untreated Fellow Eye

Corneal Changes After Crosslinking in Keratoconus Patients Compared to the Untreated Fellow Eye

The purpose of this retrospective study is to assess corneal changes (keratometry, pachymetry) and change in visual acuity (VA) in keratoconus patients after unilateral crosslinking treatment compared to the untreated fellow eye. The corneal measurements obtained preoperatively and 2 to 14 months postoperatively using a Pentacam rotating scheimpflug camera are analyzed. Furthermore, pre-existing or actual ocular pathology or/and ocular surgeries as potential factors involved in treatment outcome are also evaluated.

Inclusion Criteria:

• Keratoconus patients after unilateral crosslinking treatment

Exclusion Criteria:

• Morphological changes of the cornea caused be ocular infection or trauma (e.g. corneal scarring)
• Other pre-existing corneal surgery (e.g. corneal transplantation, implantation of intrastromal corneal ring segments)
