Grow your skills and help surgeons in the developing world put a dent in the backlog of cataract cases.
The World Health Organization estimates that 285 million people are visually impaired worldwide and that 90% of those people live in low-income settings.1 The most affected areas are in south and east Asia and parts of sub-Saharan Africa. Because the global population is living longer, the burden of blindness will continue to increase. The number of blind people worldwide is expected to triple by 2050.2 David F. Chang, MD, who has collaborated with many Indian and Nepalese surgeons in international cataract camps, identifies the single greatest challenge in ocular surgery as the huge backlog of cataract cases in the developing world.3 A lack of equipment and a shortage of trained ancillary staff add to the cost of phacoemulsification surgery, while comorbidities such as trauma, corneal scarring, and zonulopathy increase the complexity of cases.
AT A GLANCE
• There is an extraordinary backlog of cataract cases in the developing world that new and experienced surgeons can help address.
• Surgeons who are interested in international outreach can work with organizations such as Surgical Eye Expeditions International to identify opportunities.
• It is important for a surgeon to have a clear understanding of the expectations of the site, the country’s culture, and the patients’ customs to have a successful and educational experience.
Although phacoemulsification is possible in the under-developed world, the aforementioned considerations and usually dense cataracts at presentation make manual small-incision cataract surgery (MSICS) a better option for high-volume, low-cost cataract surgery. In India, MSICS can cost about $15 per eye; phacoemulsification costs four to six times as much. The additional upfront cost of $100,000 for a phaco machine and the need for trained technicians to calibrate and run it makes phacoemulsification a restrictive technology.
WHERE TO LEARN
While complications can arise in MSICS, there is less of a learning curve, which makes it safer and results in equivalent postoperative visual actuity. As such, it is important for US doctors to become familiar with the procedure if they wish to have a global impact in countries where technology is a barrier. Those whose training included experience with extracapsular cataract extraction can develop their skills through a wet lab offered by the American Academy of Ophthalmology. Many surgeons who routinely perform MSICS, either in their practices or in international camps, teach these wet labs.
For those interested in learning MSICS directly in the field and performing actual surgeries under faculty supervision, partner sites with Surgical Eye Expeditions International (SEE) and Vision Outreach offer second-tier courses. Long-term courses ranging from 1 to 3 months are offered through the Aravind Eye Care System. Performing cases under supervision helps surgeons understand how to handle complications such as iris bleeding and long incisions that require suturing.
HOW TO STAY FRESH
Planning MSICS for dense white cataracts can help surgeons maintain the skills required for MSICS. In my own practice, I use MSICS for the densest cataracts when I feel that comorbidities such as a crowded anterior segment, zonular weakness, corneal opacity, or severe miosis may make phacoemulsification a risky procedure for the endothelium or posterior capsule. MSICS is a wonderful option to have in my surgical armamentarium.
HOW TO GET INVOLVED
Two major subgroups of ophthalmologists travel overseas for global ophthalmology. One group consists of surgeons wishing to gain additional training, either in MSICS or simply more complex phaco cases. The other, larger group comprises experienced surgeons who want to offer their services to help in humanitarian camps and teach skills to local eye care providers. Both categories of ophthalmologists are often stuck on where to find information about possible global opportunities. Here are four places to start:
SEE (www.seeintl.org) is a nonprofit humanitarian organization based in Santa Barbara, California. Founded in 1974, SEE connects more than 650 volunteer ophthalmologists and medical professionals to host clinic sites worldwide. The organization’s website is constantly updated about current expedition needs. Last year, approximately 250 campaigns were coordinated through SEE, and for 2017, SEE is on track to screen around 100,000 patients and perform 20,000 sight-restoring surgeries.
2. Global Sight Alliance
Global Sight Alliance maintains an ongoing list of future missions, training videos, and webinars on its website (www.globalsight.org).
3. The American Academy of Ophthalmology
The American Academy of Ophthalmology maintains a database of countries needing surgeons (https://www.aao.org/global-ophthalmology-guide.
4. The University of Iowa
The University of Iowa has compiled a list suitable for residents looking for extra training (bit.ly/IowaInternational).
It is important to realize that participating in one mission camp will not solve the worlds’ cataract problem, but setting up sustainable eye care with an emphasis on skills transfer will help make a dent.
