Pupillotomy for miotic pupils by MSICS? Is this not barbaric?

Mechanical Pupillotomy for narrow pupils

No, it is definitely not. On this picture you will see one in a 70 year old lady, who underwent a complications free MSICS with massive pseudoexfoliations and miotic pupil.

In EnglishPupillotomy is an excellent method for defusing a potential bomb during MSICS with narrow pupils when:
1) mechanical stretching of the pupil has not yielded any results (e.g., in PEX),
2) iris hooks or a Malyugin ring are not available,
3) additional risks, such as a wrinkled fibrous capsule or a very large nucleus, are present.

At that time (and up to date) I couldn’t find a better solution. By the way, it’s a fairly mature MSICS, with several hundred operations under my belt.

After patients had been living with just a perception of light, this cosmetic issue didn’t matter to them. A complication-free surgery in situations where such complications would be nearly impossible to fix far outweighs any cosmetic concerns. Interestingly, the remaining sphincter still works somehow πŸ™‚ – The pupil even reacts a little.
P.S. At the 1 o’clock position, there is hyperpigmentation, which often occurs during the healing of a conjunctival wound in patients with racial melanosis. A year 2016.

How my MSICS began

Senanga town, Western Province of Zambia. April 2014.

Senanga, April 2014


Here is how it all happened that day. My future wife was with me on my first day in the operating room and was able to take these photos. It was incredibly unusual, my heart was bursting with a thirst for new experiences, surrounded by new people, new impressions every working day. In April, my boss and later a good friend David finally agreed to teach me manual small incision cataract surgery (MSICS). Before that, I had the honor of observing his art for several months non-stop. The burning call of fearless youth… Even now, as I study phaco, it’s not as sharp or exciting as it used to be that days.
Mistakes were surely made. My teacher had to correct my sclerocorneal tunnels more than once.
Pay attention to the instrument table. That is exactly how much you need to effectively remove cataracts without a phaco machine and sutures.

And after the operating days, we sat together on the banks of the Zambezi River and enjoyed the sunset, not knowing that those were some of the best days of our lives.

Senanga, September 2015

Later, when I grew up and my teacher left me, I started doing independent outreach trips. This next photo is from the same town of Senanga, but already from September 2015.

Behind me are cataract patients operated on in one day. Yes, the amount of good that can be done using that limited set of instruments from the previous photos is global in both direct and figurative senses. Global ophthalmology rocks.

MSICS virtual simulator

The guys from HelpMeSee have developed an alternative to Eyesi for manual small incision cataract surgery. Not sure if the target developing countries will have the access to it, but it’s just the beginning…

Sunconjynctival anesthesia for MSICS?

Colleagues from India published recently a RCT, which evaluated subconjunctival anesthesia for manual small incision cataract surgery.

Not surprisingly, it does not provide akinesia. However, its anesthesia is sufficient for more or less comfortable surgery. It’s only obstacle is a chemisis, which is especially disturbing for novice surgeons.
