Bolivar G, et al. - In this ex-vivo experimental animal study, researchers assessed the rise in intraocular pressure (IOP) in porcine eyes during laser in situ keratomileusis (LASIK) performed using 3 femtosecond (FS) laser platforms. They noticed that the mean IOP increase during suctioning was significantly raised with the iFS (78.14 ± 23.6 mmHg) when compared with the Victus (20.28 ± 6.7 mmHg). To obtain the consequences of the suctioning phase alone, the LenSx performed the suctioning and applanation phases simultaneously. A lower IOP elevation during the cutting phase was noticed with the LenSx (20 ± 5.3 mmHg) vs the iFS (108.1 ± 17.0 mmHg) and Victus (96.4 ± 16.8 mmHg) systems. They also found significantly lesser total surgical time with the LenSx (17.21 ± 0.7 seconds) as compared to the iFS (25.10 ± 4.3 seconds) and Victus (33.40 ± 0.7 seconds) systems. They overall concluded induction of higher IOP increases with iFS and Victus FS systems which required longer surgical times to cut a LASIK flap than the LenSx.
