How common is endophthalmitis after cataract surgery?

The short answer? 0.04%.

A new retrospective study reviewed the charts of 5.4 million patients who had cataract surgery between 2013 and 2017. They identified patients who developed acute-onset postoperative endophthalmitis within 30 days after cataract surgery and found that it occurred in 0.04% of these patients

Who was more likely to get this?

A couple of groups had a higher risk:

1. Younger patients. The incidence of endophthalmitis was highest among patients aged 0 to 17 years, followed by patients aged 18 to 44 years.

2. Combined surgeries. Endophthalmitis occurred in four times more combined cases (cataract with other ophthalmic procedures) than stand-alone cataract surgeries.

3. Anterior vitrectomy patients. Endophthalmitis was more common in patients receiving anterior vitrectomy.

WHAT YOUR PATIENT MIGHT ASK YOU

How can I decrease my risk of contact lens infection?

Your contact lens case isn't doing you any favors.

A new study examined a group of ortho-k wearers to evaluate the risk factors associated with lens case contamination. The research team surveyed the patients’ cleaning habits and collected their cases, which had been in use between 1 and 3 months.

What were they looking for in the cases?

Biofilms! Biofilms in cases can increase the risk of microbial infections.

So, how can we prevent biofilm formation? 

The study concluded the following:

1. Change the case monthly. This study disagrees with the current FDA recommendation of 3 to 6 months. The older the case, the more contamination found.

2. Use a cylindrical case, rather than a flat case with ridges. The cylindrical design (like this one used in the study) may reduce the chance of contact between fingers and the inner surface of the case, thus reducing contamination.

3. Rinse with multipurpose solution (MPS) and wipe dry with a tissue daily. Rinsing with an MPS solution is great, but can leave behind salt-like deposits, which can reduce contact lens comfort. However, wiping with a tissue can remove residual MPS and substantially reduce the microbial burden in the case.

Recycle your glasses lenses!

Costa has expanded its Kick Plastic Lens Recycling Program. You can mail your discarded optical lenses and waste to one of their facilities and it will be repurposed into safety glasses and motorcycle helmets.


There is a Groupon for everything.

If going through Groupon for LASIK seems weird to you, how about getting a Groupon for a chest CT


Do you ever see tiny peripheral dot hemes on Optos in an otherwise healthy patient?

Me too. So I asked the opinion of my Instagram followers for an answer. Read what other ODs and OMDs said here.

OD HIGHLIGHT

This week I want to highlight Bob and Kim Molter. They are a husband and wife optometry team that moved to Vietnam 3 years ago to work at the new optometry school there. Bob and Kim helped to pioneer some of the school’s teaching strategies with help from the Brien Holden Vision Institute and got to see the first class of 12 students graduate last year. This is the Molters’ last year at the school and they are looking for another OD to replace them. If you want to learn more about this opportunity, please reach out to Bob Molter here or Kim Molter here.

Great work both of you!
