“…Risk factors for a suprachoroidal haemorrhage include older age, high intraocular pressure, a history of systemic cardiovascular disease, systemic hypertension and complicated cataract surgery. 13 When it occurs, it is recognised by sudden shallowing of the anterior chamber and iris prolapse associated with progressive loss of the red reflex and raised intraocular pressure. Wounds should be sutured immediately and intraocular pressure lowered with systemic acetazolamide or mannitol.…”

Modern cataract surgery is safe in more than 95 per cent of patients. In the small number of cases where a serious complication occurs, the most common is an intra-operative posterior capsular rupture. This can lead to vitreous loss or a dropped nucleus and can increase the risk of post-operative cystoid macular oedema or retinal detachment. Postoperatively, posterior capsular opacification is the most common complication and can be readily treated with a YAG capsulotomy. The most devastating complication is endophthalmitis, the rate of which is now significantly decreased through the use of intracameral antibiotics. As a clinician, the most important step is to assess the patient pre-operatively to predict higher risk individuals and to counsel them appropriately. In these patients, various pre-or intra-operative management steps can be taken in addition to routine phacoemulsification to optimise their visual outcome.

“…Taking cardiovascular medication seemed to be a better predictor of SCH than hypertension and elevated preoperative SBP. 27 A study by Lee et al 28 identified ischaemic heart disease, heart failure, and renal failure as risk factors for perioperative cardiac complications. In our series, there were 428/734 (58.3%) hypertensives who suffered from pre-existing systemic hypertension of which 211 (49%) had only systemic hypertension, whereas 84 patients had coexisting diabetes, renal failure (n ¼ 34), associated cardiac disease (n ¼ 67), and 32 had also suffered from stroke in the past.…”

Purpose The practice of deferring phacoemulsification procedure on recording raised blood pressure (BP) in the immediate perioperative period is based on the perception of increased intraoperative risk. The significance of perioperative BP recordings on the surgical complications during phacoemulsification procedure was evaluated. Setting: Hairmyres Hospitals, Lanarkshire Acute Hospitals NHS Trust. Patients and methods Patients were classified as hypertensive on the basis of the British Hypertension Society Guidelines. BP recordings during preoperative assessment, admission, and 1-hour postoperatively were recorded in 734 hypertensives and 740 normotensives undergoing phacoemulsification procedure. In addition, BP recordings in the holding area before giving local anaesthesia were noted in the 734 hypertensives. Patient's peri-and intraoperative complications during the procedure were noted. Results The mean age was 72 ± 10.5 years and 74±11.6 years among the hypertensives and normotensives. There was a significant increase in the number of hypertensives who developed isolated systolic hypertension in the holding area (95% confidence interval ¼ 2.82, Po0.001) where the mean BP was 171.38/78.31 mm Hg ( ± 30.55/16.29). A total of 21 hypertensives and 18 normotensives developed intraoperative complications during the phacoemulsification procedure. There was no significant difference (P ¼ 0.41) in the intraoperative complications between the hypertensives and normotensives. Conclusion Perioperative increase in BP noted in the holding area among hypertensives did not increase the risk of surgical complications during phacoemulsification procedure when compared with normotensives. We recommend that BP should not be routinely measured in the holding area before phacoemulsification surgery under local anaesthesia.

“…The evidence regarding the use of antibiotics in the irrigating solution during cataract surgery is conflicting. [5][6][7] For this study a surprisingly high percentage of cases receiving intraoperative antibiotics (75%) showed bacterial growth from the ocular samples taken at the time of treatment for endophthalmitis. Unfortunately, we were unable to speculate on the effectiveness of the intraoperative antibiotics as the antibiotic sensitivity data on the organisms cultured was not retrieved.…”

“…The controls for this study were shared with another BOSU case-control study of 'suprachoroidal haemorrhage complicating cataract surgery'. 5 Two study investigators (SK and RL) visited the 13 control centres to retrieve data from the patient notes. The two investigators compared independently retrieved data from a single pilot centre to ensure standardisation of the data retrieval from the cases notes.…”

Aims To study risk factors for presumed infectious endophthalmitis complicating cataract surgery in the United Kingdom. Methods Two hundred and fourteen clinically diagnosed patients with presumed infectious endophthalmitis were compared with 445 control patients throughout the United Kingdom in a prospective case-control study. The cases were identified through the British Ophthalmological Surveillance Unit reporting card system. Control patients undergoing cataract surgery from 13 'control centres' throughout the United Kingdom were selected randomly. Risk factors were identified by univariate and multivariate logistic regression analyses. Pertinent variables relating to the cataract extraction procedure, antimicrobial prophylaxis, ophthalmic and medical history were analysed with regard to postoperative infection. Results Statistically significant risk factors in the multivariate model included inpatient cataract surgery (P ¼ 0.001), surgery in dedicated eye theatres (Po0.001), consultant grade surgeon (compared to registrar) (P ¼ 0.001), posterior capsule tear during cataract surgery (P ¼ 0.001). The use of face masks by the scrub nurse and surgeon during cataract surgery (Po0.001) and the administration of subconjunctival antibiotics at the end of surgery (Po0.001) were protective against postoperative infection. Conclusions In order to minimise the risk of postoperative endophthalmitis we would recommend the wearing of face masks by the surgeon and scrub nurse during cataract surgery and subconjunctival antibiotics at the end of surgery.
