Purpose
To evaluate structural and functional changes in the optic nerve and the macula after Femtosecond Laser-Assisted Cataract Surgery (FLACS) and compare them with those seen after conventional cataract surgery (CCS) in eyes with ocular hypertension and mild glaucoma.
Setting
Vithas Eurocanarias Instituto Oftalmológico. Las Palmas de Gran Canaria. Spain
Methods
This retrospective study included patients with ocular hypertension or mild glaucoma who had undergone CCS or FLACS using a LenSx platform. For structural analysis, optical coherence tomography (OCT) measurements of Bruch’s Membrane Opening-Minimum Rim Width (BMO-MRW), Retinal Nerve Fiber Layer (RNFL) and Macular Thickness (MT) were performed preoperatively, one month and six months after surgery. For functional analysis, visual field index (VFI) and Mean Deviation (MD) of the visual field were evaluated preoperatively and six months after surgery.
Results
A total of 164 eyes were included, 70 in CCS group and 94 in FLACS group. After surgery, no deterioration in OCT parameters was observed. Preoperative BMO-MRW, RNFL, MT, VFI and MD were 291.31±52.25µm, 92.87±11.60µm, 269.21±19.59µm, 97.61±2.77% and -1.22±1.77dB in CCS group, and 283.13±58.39µm, 94.87±11.08µm, 271.29±21.63µm, 98.03±2.07% and -0.96±1.78dB in FLACS group. A slight increase in BMO-MRW, RNFL and MT was found in both groups (P<0.001); VFI and DM remained stable. There were no differences between the two groups in any of the analyzed parameters.
Conclusions
The results of our study suggest that, in eyes with ocular hypertension and mild glaucoma, FLACS is as safe for the optic nerve and the macula as CCS. Results could be different with other femtosecond laser platforms and in moderate or advanced glaucoma.
