Calculating surgical costs

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.

Rate of pterygia positive for OSSN

In the western world it is rare, to miss an OSSN and excise it as pterigium without no-touch technique etc. In one retrospective study from the US it was only in 0,3% of all cases of pterygium excision.

In tropical Africa, such cases are much more often. And vice versa, it is also commom to see a very suspective pterygium, that upon pathology proves to be benign… See this: Case 1 and Case 2

How bad do our patients instill the eyedrops? Case of Nigeria

Assessment of eye drop instillation techniques among patients with primary open angle glaucoma in a Nigerian tertiary hospital
Olapeju A Sam-Oyerinde et al. Int Ophthalmol. 2021.

Approximately everyone does not wash their hands before the instillation. And ~30-40% touch the eye during inatillations. This was tested in Nigeria on glaucoma patients.
