To compare the functional and morphological results of femtosecond laser clear corneal incision (FSL-CCI) and manual CCI (M-CCI).
Ophthalmolohy Clinic, Department of Medicine and Ageing Science, University G. d"Annunzio of Chieti-Pescara, Italy
Sixty eyes of 60 patients who underwent CCI during cataract surgery were divided into two groups: FSL-CCI (group 1-30 eyes) and M-CCI (group 2 -30 eyes). The follow-up was 90 days.
There were no significant differences between the two groups regarding uncorrected, best corrected visual acuity and higher order corneal aberrations. The analysis of surgical induced astigmatism (SIA) showed a lower variability in group 1 (0.64ḟ0.32 D) compared to group 2 (0.69ḟ0.50 D). Central corneal endothelial cells count (ECC) was significantly higher in group 1 compared to group 2 at 7 and 30 days (p <0.05). At 30 and 90 days a lower increase of corneal thickness at the incision site was observed in group 1 compared to group 2 (p <0.05). The total time of phacoemulsification and the cumulative dissipated energy were significantly lower in group 1 compared to group 2 (p <0.05).
Femtosecond laser is safe and effective for creating clear corneal incision. It induces lower SIA variability, higher central corneal ECC and lower increase of corneal thickness at the incision site compared to the manual technique.
