Cataract surgery practices in the United States Veterans Health Administration

Oral anxiolytics prior to routine resident cataract surgery eliminate need for intravenous sedation at a Veterans Affairs Hospital

Purpose

To assess the frequency of intraoperative intravenous sedation administration during routine resident-performed cataract surgery among patients receiving pre-operative oral sedation at a Veterans Affairs Medical Center and its impact on patient safety and system cost.

Methods

Retrospective review of all resident-performed cataract surgeries performed at the Iowa City Veterans Affairs Medical Center in 2013 and 2017. Cases monitored by a registered nurse were included. Combined cases and cases monitored by an anesthesia provider were excluded. Pre-operative placement of an intravenous (IV) catheter, administration of intra-operative IV sedation, oral diazepam administration, anesthesia type, conditions for administering intraoperative IV medication, and cost of IV catheter placement were recorded.

Results

Of 1025 patient cases included for analysis, 972 received pre-operative diazepam (94.9%) and 1017 (99.3%) had IV catheters placed. One patient received a planned dose of IV methylprednisolone. Zero patients received supplemental intraoperative IV sedation. The estimated materials cost of unused IV catheters was $10,668 over 2 years.

Conclusions

Pre-operative IV catheter placement may not be necessary in patients undergoing routine resident cataract surgery with pre-operative oral sedation. Discontinuation of routine IV placement may improve patient satisfaction and decrease health care costs without compromising patient safety.

Visual function and mobility after multifocal versus monofocal intraocular lens implantation

Clinical relevance: Mobility and fall risk may be important considerations in choosing between intraocular lenses.Background: Fall risk in older adults increases when wearing multifocal spectacles, but little is known about mobility among individuals with different types of intraocular lenses. This study compared visual function, fall risk and balance control following bilateral implantation of monofocal or multifocal intraocular lenses.Methods: This was a non-randomised, cross-sectional study involving adults with bilateral intraocular lenses. Participants completed questionnaires concerning physical functioning, fall history and balance-related confidence. Binocular visual acuity, contrast sensitivity (Pelli-Robson chart and computerized testing), depth perception and glare sensitivity were assessed. Physical performance measures included the Sensory Organization Test, preferred gait speed, Dynamic Gait Index and wayfinding in a virtual environment.Results: Fifteen participants (mean ± standard deviation, 67.1 ± 6.8 years) had monofocal intraocular lenses and 14 participants (68.1 ± 6.1 years) had multifocal intraocular lenses. Contrast sensitivity in the monofocal group was significantly better than that in the multifocal group (p = 0.02) at intermediate and high spatial frequencies. Contrast sensitivity of the monofocal group also was less affected by glare than the contrast sensitivity of the multifocal group, at an intermediate spatial frequency (p = 0.02). However, the multifocal group had significantly better Dynamic Gait Index scores (p = 0.04), even after controlling for perceived physical function.Conclusions: The participants with monofocal intraocular lenses generally had better contrast sensitivity than did those with multifocal intraocular lenses. However, the scores on a mobility test that is associated with fall risk were worse for those with monofocal lenses.

The prevalence of preoperative medical testing and consultation in cataract surgery patients at a teaching hospital

PURPOSE

To investigate the prevalence of preoperative cataract surgery testing and consultation at a single United States teaching hospital.

SETTING

Academic-affiliated Veterans Affairs Medical Center.

DESIGN

Retrospective chart review.

METHODS

This study included patients who received cataract surgery from 2014 to 2018. For patients with bilateral cataracts, the second surgery was excluded to ensure independent selection. Charlson Comorbidity Index (CCI) scores and heart disease status were recorded. The outcomes of interest were preoperative testing, such as complete blood count, chemistry panel, and echocardiography, and consultation (office visits to non-ophthalmologists) during the period between the date the decision was made to proceed with surgery and the cataract surgery date.

RESULTS

For this study 1320 charts were reviewed; 1257 (95.2%) patients met the study criteria. The mean CCI score was 1.7; 42.0% (528/1257) had heart disease. The prevalence of preoperative testing was 0.08% (1/1257). The prevalence of preoperative consultation was 4.2% (53/1257); 86.8% (46/53) of patients received cardiology consultation; 17.0% (9/53) pulmonology; and 15.1% (8/53) primary care. Of the patients who received cardiac consultation, 63.0% (29/46) had heart disease; the remaining had an electrocardiogram abnormality.

CONCLUSIONS

There was a low prevalence of preoperative testing and consultation for cataract surgery at this teaching hospital. Further studies using medical record data are needed to assess the current rates and the role of preoperative testing and consultation for cataract surgery patients.

Cataract Surgery Practices in the Republic of Korea: A Survey of the Korean Society of Cataract and Refractive Surgery 2018

Purpose

To describe current cataract surgery practice patterns and changing trends among Korean ophthalmologists.

Methods

A survey of members of the Korean Society of Cataract and Refractive Surgery was performed in July 2018. One hundred and two (12.7%) of 801 questionnaires were returned for analysis. The data were analyzed using descriptive statistics and compared with previous surveys.

Results

Most of the respondents (75%) had been in practice for 6 or more years and performed an average of 31 cataract surgeries per month. The preferred method for cataract surgery was phacoemulsification (95%); 5% used a femtosecond laser. The use of topical anesthesia markedly increased from 69% (2012) to 80% (2018). The use of optical biometry exceeded that of ultrasound A-scan biometry. A multifocal intraocular lens was used by 76% of the respondents compared with 44% of the respondents in 2012. Topical nonsteroidal anti-inflammatory drugs were used by 70% of the respondents postoperatively. Most (59%) of these anti-inflammatory drugs were prescribed for 4 weeks.

Conclusions

This survey provided a comprehensive update of the present cataract surgery practices in the Republic of Korea. The results emphasized the increasing use of premium intraocular lenses, optical biometry, and topical anesthesia.
