Femtosecond laser pretreatment linked to small, transient increase in IOP
Femtosecond laser pretreatment to cataract surgery was associated with a slight, transient increase in IOP without complications, according to a study.
In the interventional, prospective study, 25 eyes of 25 patients underwent femtosecond laser pretreatment using the Catalys system with Liquid Optics interface (OptiMedica).
Mean IOP increased from 17.5 mm Hg at baseline to 28.9 mm Hg during vacuum application and 36 mm Hg after laser anterior capsulotomy and lens fragmentation (P < .001).
IOP decreased to 26.6 mm Hg after suction ring removal (P < .001).
Mean IOP increase from baseline was 18.5 ± 4.7 mm Hg.
Because the majority of cataract patients are older and may be more vulnerable to IOP complications due to concomitant disease, it may be important to minimize the increase in IOP during femtosecond laser pretreatment, the researchers said.
