Intraocular pressure before and after cataract surgery in participants of the Melbourne Visual Impairment Project

Abstract

The purpose of this study was to investigate the effect of cataract surgery on intraocular pressure (IOP) in a cluster-stratified random sample of the population of Victoria, Australia. A total of 3271 participants aged 40 years or older were examined at baseline for the Visual Impairment Project. The baseline study (1992-1994) was followed by a 5-year incidence study The IOP data were compared between participants who had cataract surgery between the two stages of the study and participants with and without cataract at follow up. The IOP was also compared before and after cataract extraction in glaucoma participants. An eligible 89 non-glaucoma and 24 glaucoma participants had cataract surgery between the two time points. The analyses showed that IOP increases with age in non-operated eyes in both glaucoma and non-glaucoma groups. However IOP decreased significantly after cataract surgery in eyes with glaucoma but did not change significantly in non-glaucoma participants.

The relationship between intraocular pressure and refractive error adjusting for age and central corneal thickness

“…In addition, a number of people excluded in the present study, such as those with a history of eye surgery and current contact lens users, may influence our findings. Cataract surgery should influence the IOP value and the refractive errors of the subjects (Cekic et al, 1998;Dimitrov et al, 2001), and epithelial oedema caused by contact lens wearing should lead to the overestimate of corneal thickness (Whitacre and Stein, 1993). Therefore, some differences between those individuals included and excluded in the present study seems to be inevitable.…”

Reduction in admissions of patients with acute primary angle closure occurring in conjunction with a rise in cataract surgery in Taiwan

“…1995; Kim 1996; Issa et al. 2005); however, other studies have reported no significant postoperative changes in IOP (Dimitrov et al. 2001).…”

“…Dimitrov et al. (2001) reported that in both glaucoma and non‐glaucoma groups there were corresponding increases in IOP in non‐operated eyes with increasing age.…”

Katarakt-Operation bei Patienten mit Glaucoma fere absolutum

“…Die Ergebnisse einer von uns durchgeführten retrospektiven Untersuchung zeigten mittelfristig eine Reduktion des intraokularen Druckes und der antiglaukomatösen Therapie bei Patienten mit primärem Offenwinkelglaukom nach Phakoemulsifikation. Bei mehreren neueren Untersuchungen sind ähnliche Resultate beschrieben [9,12,20,21,26].…”
