Purpose

To quantify the change of higher order aberrations due to descemet stripping only (without using a transplant).

Setting

Sydney Eye Hospital, Sydney, Australia. Prospective study.

Methods

This prospective study included patients with Fuchs dystrophy scheduled for surgery. In all cases corneal higher order aberrations were measured using the iTrace device (Tracey technoilogies, USA). Descemet stripping only (DSO) was performed by one experienced corneal surgeon (GM). Patients were followed up frequently until 12 months after surgery. Additionally to iTrace measurements, Pentacam HR (Oculus, Germany) measurements were taken as well as autorefraction, subjective refraction and slit lamp images.

Results

In total 25 patients eyes of 25 patients were included in this study. Increase in best corrected visual acuity was 7 letters on the ESCRS chart (SD: 3.0 letters). There was no significant refractive shift and no significant change in higher order aberrations. Z40 (spherical aberration) increased slightly after DSO by 4.1% (SD: 2.4%). This change was not found to be significant.

Conclusions

There is no relevant change concerning lower or higher order aberrations. Therefore, the procedure of DSO appears to increase visual quality.
