AI Summary
Highly myopic eyes are more prone to early post-cataract surgery IOP spikes, with male sex, longer axial length, shallower anterior chamber, and larger beta-PPA being risk factors, guiding closer monitoring.
Abstract
Purpose
To investigate the incidence of the early transient intraocular pressure (IOP) spike after cataract surgery in eyes with highly myopic cataract (HMC) and associated risk factors.
Methods
Consecutive patients treated with phacoemulsification were recruited. IOP was measured before and 1 day, 3 days, 1 week and 3 months after surgery. Axial length (AL) and anterior chamber depth (ACD) were recorded, and optic disc tilt, rotation and beta-zone peripapillary atrophy (β-PPA) were measured from fundus photographs taken 1 week after surgery. Backward stepwise multiple linear regression was used to investigate the risk factors for early transient IOP spike in the HMC group.
Results
Finally, 94 eyes of 94 HMC patients and 67 eyes of 67 age-related cataract (ARC) controls were included in analysis. The incidence of early IOP spike was 10% in the ARC group and 28% in the HMC group (OR=3.277, p<0.05) at 1 day after surgery. In the HMC group with IOP spikes, more males were seen and affected eyes showed longer AL, shallower ACD, greater optic disc tilt, and larger β-PPA than those without (all p<0.05). Multivariate analysis showed that sex, AL, ACD, and area of β-PPA were significantly associated with an early transient IOP spike in HMC eyes (all p<0.05).
Conclusions
Highly myopic eyes are more susceptible to early transient IOP spike after cataract surgery, and male sex, longer AL, shallower ACD, and greater β-PPA are associated risk factors.

The incidence of early transient intraocular pressure (IOP) spike after cataract surgery was 10% in the age-related cataract (ARC) group and 28% in the highly myopic cataract (HMC) group (OR=3.277, p<0.05) at 1 day after surgery.
In highly myopic cataract (HMC) eyes with early transient intraocular pressure (IOP) spikes after cataract surgery, more males were observed, and affected eyes showed longer axial length (AL), shallower anterior chamber depth (ACD), greater optic disc tilt, and larger beta-zone peripapillary atrophy (β-PPA) compared to those without IOP spikes (all p<0.05).
Multivariate analysis showed that male sex, longer axial length (AL), shallower anterior chamber depth (ACD), and larger area of beta-zone peripapillary atrophy (β-PPA) were significantly associated with an early transient intraocular pressure (IOP) spike in highly myopic cataract (HMC) eyes after cataract surgery (all p<0.05).
Highly myopic eyes are more susceptible to early transient intraocular pressure (IOP) spike after cataract surgery.
