Abstract Details

Purpose:

To evaluate anterior and posterior elevation changes after corneal collagen crosslinking (CLX) for progressive keratoconus.

Setting:

Balıkesir University Medical Faculty, Ophthalmology Department

Methods:

Sixteen eyes of 10 patients were enrolled. Corneal topographic analyses (Sirius, CSO) including maximum keratometry reading (Kmax), minimum keratometry reading (Kmin), central corneal thickness (CCT), and anterior and posterior elevation at the apex were recorded before and after corneal CXL. Uncorrected visual acuity (UCVA) and best spectacle-corrected visual acuity (BSCVA) were also evaluated.

Results:

Results: The mean follow-up time was 10 months. At preoperatively Kmax and Kmin were 52.38±3.84 diopter (D) and 47.22±2.69 D, respectively. There was no statistically significant change in these values at the last visit (p˃0.05, 52.56±4.59 D and 47.14±2.89 D, respectively). The mean anterior elevation was 33.78±16.89 micron (µm) preoperatively and 32.84±16.14 µm at the last visit (p˃0.05). The mean posterior elevation was 68.85±33.33 µm preoperatively and 71.81±30.58 µm at the last visit (p˃0.05). There was no statistically significant difference in terms of BSCVA, UCVA and CCT. (p˃0.05).

Conclusions:

Conclusion: Anterior and posterior elevation values as well as keratometric readings seem to be stable 10 months after CLX in progressive keratoconus.
