“…). One hypothesis is that when a cataract is so dense that vision is impaired, it reflects the presence of systemic factors such as diabetes that increase the mortality of the patient (Ninn‐Pedersen & Stenevi ). Interestingly, women above 80 years in our study who had cataract surgery in either public hospitals or private hospitals/clinics had a SMR that was statistically significantly below one.…”

ABSTRACT.Purpose: To study the epidemiology and mortality in patients who had cataract surgery in public hospitals and private hospitals/clinics in Denmark between 2004 and 2012 and to assess the validity of the Danish cataract registries. Methods: Register-and chart-based study. Results: A total of 411 140 cataract operations were performed in 243 856 patients. Patients who had cataract surgery in public hospitals had an overall statistically significantly 62% higher mortality compared to patients who had cataract surgery in private hospitals/clinics. The decrease in mean age at first eye cataract surgery in private hospitals/clinics was statistically significantly greater compared to the decrease in mean age at first eye cataract surgery in public hospitals (p < 0.001). The median time interval between first and second eye cataract surgery decreased statistically significantly during the study period (p < 0.001) and was statistically significantly shorter in all calendar years for patients operated in private hospitals/clinics compared to patients operated in public hospitals (p < 0.001). In all, 46% of the cataract operations performed in private hospitals/clinics that led to cases of postoperative endophthalmitis were not registered in any registry. Conclusion: In general, patients who had cataract surgery in private hospitals/ clinics were healthier, had first eye cataract surgery at an increasingly younger age and had a reduced time interval between cataract surgeries in the two eyes compared to patients who had cataract surgery in public hospitals. The lack of registration of cataract surgery by the private hospitals/clinics limits the quality of the registries.

“…This confirms previous findings for ECCE surgery (NinnPedersen & Bauer 1996). The mortality of cataract patients has been reported to be increased, particularly for younger patients and diabetes patients (Ninn-Pedersen & Stenevi 1995;Knudsen et al 1999;Christen et al 2000;Wang et al 2001;Reidy et al 2002;Borger et al 2003;Clemons et al 2004). In our population this was only true for men and for patients undergoing surgery on only one eye within the study period (Table 4).…”

. 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.

“…However, the results of more recent population-based [4,9,12,18,22,26,27,28] and case-control [29] studies indicate that lens opacities are indeed associated with a higher risk of death, although there are some discrepancies regarding the specific types of cataract representing risk and how they are related to other factors that might be involved. Shorter survival has also been documented in patients undergoing cataract surgery than in those subjected to other surgical procedures [2,10,13,16,17,19,25].…”
