Abstract Details

Purpose:

Alberto Rodero, Miguel A. Teus, Isabel Rodriguez, Esther Arranz, Carmen Bouza.

Setting:

Clínica Novovisión, Madrid, Spain. Private practice.

Methods:

Observational, prospective, masked, cohort study. 114 myopic eyes were included in the study, 64 eyes operated with FS-LASIK (Intralase®) and 50 eyes with SA. RNFL thickness was measured with spectral domain Ocular Coherence Tomography (OCT) (Spectralis, Heidelberg Engineering). We compared the RNFL thickness measurements preoperatively and at 3 months post-op in both groups.

Results:

There were no significant differences in the preoperative examination between groups in terms of refraction, age or sex. FS-LASIK group had a significantly higher central corneal thickness than those in the SA group (562.4 ± 31.6μm vs 529.1± 36.1 μm) (P=0.0001). We found a very small, but statistically significant increase in the RNFL thickness in the FS-LASIK group (93.09 ± 8.4μm vs 93.76 ± 8.2μm; preop vs 3 months postop) (P= 0.008). No statistically significant differences were found in the RNFL thickness in the SA group (88.14 ± 9.6 μm versus 88.56 ± 9.6 μm; preop vs 3 months postop).

Conclusions:

Based on our results, in the corneal laser refractive surgery scenario, the use of a suction ring, that does cause a significant increase in the IOP during the procedure, does not induce any reduction of the RNFL thickness.
