TL;DR: Pressure reduction on fewer medications was clinically and statistically significantly better 1 year after stent plus cataract surgery versus cataracts surgery alone, with an overall safety profile similar to that of catarACT surgery alone.

TL;DR: Routine medical testing before cataract surgery does not measurably increase the safety of the surgery and analysis stratified according to age, sex, race, physical status, and medical history revealed no benefit.
Abstract: Background Routine preoperative medical testing is commonly performed in patients scheduled to undergo cataract surgery, although the value of such testing is uncertain. We performed a study to determine whether routine testing helps reduce the incidence of intraoperative and postoperative medical complications. Methods We randomly assigned 19,557 elective cataract operations in 18,189 patients at nine centers to be preceded or not preceded by a standard battery of medical tests (electrocardiography, complete blood count, and measurement of serum levels of electrolytes, urea nitrogen, creatinine, and glucose), in addition to a history taking and physical examination. Adverse medical events and interventions on the day of surgery and during the seven days after surgery were recorded. Results Medical outcomes were assessed in 9408 patients who underwent 9626 cataract operations that were not preceded by routine testing and in 9411 patients who underwent 9624 operations that were preceded by routine testing. The most frequent medical events in both groups were treatment for hypertension and arrhythmia (principally bradycardia). The overall rate of complications (intraoperative and postoperative events combined) was the same in the two groups (31.3 events per 1000 operations). There were also no significant differences between the no-testing group and the testing group in the rates of intraoperative events (19.2 and 19.7, respectively, per 1000 operations) and postoperative events (12.6 and 12.1 per 1000 operations). Analyses stratified according to age, sex, race, physical status (according to the American Society of Anesthesiologists classification), and medical history revealed no benefit of routine testing. Conclusions Routine medical testing before cataract surgery does not measurably increase the safety of the surgery.

TL;DR: In this article, a prospective study of 85 cataract eyes to improve refractive outcome of catarach surgery due to a more accurate calculation of intraocular lens power was performed by using the SRK II formula using ultrasound biometry data.

TL;DR: The visual acuity outcomes were worse in the patients who developed endophthalmitis after PPV than after cataract extraction, glaucoma procedures, or secondary IOL implantation, and these results may serve as a source of comparison for other centers and future studies.

TL;DR: The published literature indicates that modern cataract surgery yields excellent visual acuity and, although not free of complications, is a very safe procedure regardless of the extraction technique used.
Abstract: Objective: To better define the effectiveness and risks of modern cataract surgery Design: Meta-analysis (formal systematic identification, selection, review, and synthesis) of published literature Patients: Patients described in 90 studies published between 1979 and 1991 that addressed visual acuity (n=17 390 eyes) or complications (n=68 316 eyes) following standard extracapsular cataract extraction with posterior chamber intraocular lens implantation, phacoemulsification with posterior chamber intraocular lens implantation, or intracapsular cataract extraction with flexible anterior chamber intraocular lens implantation Main Outcome Measures: The proportion of eyes with postoperative Snellen visual acuity of 20/40 or better and the proportion of eyes with each of 18 complications Results: The pooled percentage of eyes (weighted by sample size) with postoperative visual acuity of 20/40 or better was 955% (95% confidence interval [CI], 951% to 959%) among eyes without preexisting ocular comorbidity and 897% (95% CI, 893% to 902%) for all eyes The pooled percentage of eyes experiencing complications (weighted by sample size and, when pertinent, by quality score of the individual studies but not adjusted for variation in duration of follow-up) ranged from 013% for endophthalmitis to 197% for posterior capsule opacification Pooled proportions of eyes with other complications were as follows: bullous keratopathy, 03%; intraocular lens malposition/dislocation, 11%; clinically apparent cystoid macular edema, 15%; and retinal detachment, 07% Pooled results for postoperative Snellen visual acuity and most complications were similar for surgery performed via phacoemulsification vs standard extracapsular cataract extraction, although comparisons of the outcomes between these procedures should be interpreted with caution Conclusions: The published literature indicates that modern cataract surgery yields excellent visual acuity and, although not free of complications, is a very safe procedure regardless of the extraction technique used
