. Purpose: To determine the longterm risk of pseudophakic retinal detachment (PRD) in a defined population undergoing standardized phacoemulsification surgery at a single centre. Design: We carried out a register‐based, retrospective, consecutive, uncontrolled study. All 6352 eyes that underwent cataract surgery at our institution during the years 1996–1998 were included in the study. The main outcome measure was the incidence of surgery for PRD. Methods: Cataract‐operated eyes were identified by a search in the local hospital registry. Eyes that subsequently underwent surgery for PRD were identified by a search in the Danish Patients Registry (LPR). Follow‐up ended by 31 December 2003. Eyes in patients who died before that date were censored. Results: The 8‐year cumulated incidence of PRD after phacoemulsification was 0.93 per eye (95% CI 0.65–1.33). This is 8.77 (95% CI 7.12–10.72) times higher than expected in eyes that do not undergo cataract surgery. The incidence rate for retinal detachment was significantly higher in pseudophakic eyes than in the background population for at least 6 years after surgery. Patient mortality was slightly increased for men, but no different for women from that of the background population. Conclusion: For eyes undergoing phacoemulsification surgery, the cumulated incidence of PRD continues to increase for at least 8 years after surgery. Comparison of the cumulated incidence of PRD between different studies requires equal lengths of follow‐up.
The incidence of RD after phacoemulsification cataract extraction in an unselected group of patients was low. A long axial length, young age, and male sex were confirmed as risk factors.
performed from 2002 to 2010 (excluding congenital and childhood cataracts) were drawn from the database yielding a total of 14,701 eyes (9,474 first eye surgeries and 5,227 second eye surgeries). To avoid problems with inter-eye interaction, the analyses were separated into first eye surgeries and second eye surgeries. However, only second eyes that were operated on within one year of the first eye were included in the second eye analyses (n=4.677). Thus, 550 eyes that were operated more than 1 year later than the first eye were excluded from the study.At the pre-operative visit all patients had a full ophthalmic examination including determination of best corrected visual acuity and a thorough slitlamp examination after pharmaceutical pupil dilation as well as biometric measurements including determination of axial length and radii of curvatures. Furthermore, patients were interviewed about cataract related symptoms as well as general health status. Any ocular co-morbidities were evaluated. For the statistical analyses, patients were grouped into those with ocular co-morbidities thought to be of significance for the visual acuity (e.g. age-related macular degeneration, glaucoma, previous retinal detachment, or previous vitreoretinal surgery) and those who did not have visually significant ocular co-morbidity (e.g. no other eye disease except cataract or visually insignificant eye disease such as blefaritis).Statistical analyses were performed using the SAS computer AbstractBackground: Due to the increasing proportion of elderly citizens the need for cataract surgery is expected to increase markedly within the next two decades but also the indication level for cataract surgery will influence the need for surgery. The aim of the present study was to examine if the indication for cataract surgery has remained stable over an eight year period in a university clinic setting in the Capitol Region of Copenhagen, Denmark.Methods: All pre-operative visits from 2002 to 2010 were evaluated yielding a total of 14,701 eyes (9,474 first eye surgeries and 5,227 second eye surgeries). Information was drawn from a database where pre-, peri-and postoperative data regarding all cataract surgeries (except for congenital and childhood cataract) performed at the clinic had been entered at the time of examination/surgery. Evaluation of the indication level for cataract surgery was assessed primarily based on visual acuity. Results:In the 8 year period, mean visual acuity increased significantly from 0.18 to 0.24 Snellen (corresponding to 0.74 to 0.62 logMAR) in the eyes that underwent surgery first and in second eyes from 0.29 to 0.41 Snellen (corresponding to 0.54 to 0.39 LogMAR, respectively, p-values <0.0001) and concomittantly the mean age of patients at the time of surgery decreased from 75.4 to 71.6 years in females and 72.1 to 69.1 years in males. Conclusion:During the time period from 2002 to 2010 the indication for cataract surgery changed towards patients being operated at better visual acuities and at younger ages. In the ...
