Developing an Eye Care Program in an Underserved Community Sam Powdrill University of Kentucky Previously served at Tenwek Eye Unit
Objectives • 1. Consider the setting, demographics and facilities available for eye care and surgery in underserved rural Africa • 2. Identify the challenges and barriers to eye health and the development of a program of blindness prevention • 3. Discuss appropriate and low cost options to providing eye care and cataract surgery to underserved populations

Causes of World Blindness 285 million visually impaired globally 39 million blind - 246 million low vision
80% of developing world blindness is avoidable • 60% Treatable • 20 % Preventable
Eye Care Advances in the past 30 years • 1990s Ivermectin 1987 – for Onchocerciasis • Good quality Low cost IOLs introduced in the early 1990s • MSICS use since the early 1990s • Availability Low cost glasses with injection molded lenses • Introduction of SAFE for combating Trachoma 1996
Many in Rural Africa are Blind • Out of 100 people • 1 is blind in both eyes • 3 more have significant loss of vision • 2 of these could see again with surgery Why is there so much blindness?
INCIDENCE BACKLOG PREVALENCE OPERABLE EYES BLIND PEOPLE CSR RECEIVED SURGERY MORTALITY
1 in 1000 blind 1 in 100 blind another 1% severely visually impaired Eye Care Comparison United States Africa • 1 eye doctor for 1million people • 1 eye doctor for 20,000 people • 300 cataracts done per 1 million people • 5800 cataracts done per 1 million people
Estimated Profile of Blindness in Maasai and Pokot areas Corneal causes are increased by trachoma
What is the challenge? • Immediate catchment of approximately 1,000,000 people • 1% blind • 1% severely visually impaired • Half of these are from cataract • Estimated 2000 new cases for cataract surgery annually • One eye surgeon
Large numbers of people are blind from cataract Many do not come for surgery because of: A – availability B – bad outcomes C – cost D – distance E – escort F – fear
Mission Medicine can do something about this with: • Excellent Hospitals • Excellent local training programs • Community rapport • Spiritual care • Dedicated clinicians and staff
Start with good communication • What does the community think the greatest needs are? • How do they hope to meet these needs? • How can we partner with them • Only enter a community on their invitation
Community eye health Children learn how to wash their face with minimal water
Effective community Eye health • Available • Acceptable • Appropriate • Affordable Alma Atta – health for all by 2000
Advertising • Where to advertise • Local leaders • Health workers • Village or town centers • Public transport • Schools • Churches • Use simple flyers or radio • Make personal contacts • Three weeks ahead of the screening day
Mobile clinics and surgery • Mobile clinics can keep the patient volume high • Many patients do not come voluntarily for surgery • Operable cataract patients should be at least 10% of any clinic to make the clinic viable. • If the patient numbers at a clinic decline then it is time to move on • Mobile surgery increases surgical compliance • Mobile surgery is time consuming and expensive • It is better to transport the patients to where the surgeon is if possible

Focus on the common easily treatable problems • Have a small variety of effective low cost eye drops • Just keep common lowcost meds • Buy locally whenever possible • Eye drops can be made in your unit if not readily available • Have a supply of common glasses with spherical lenses – especially reading glasses • Have basic eye instruments • Refer complicated cases to the larger eye hospital
Focus on screening and reducing cataract blindness
Cataract priorities • Screening • Selection • Surgery • Spectacles
Manual Small Incision Cataract Surgery (MSICS) • Safe • Good results • Quick • Low cost • Available resources and equipment • Can be done in rural areas with limited facilities • The easiest cataract surgery method to teach in the developing world
Don’t spend a lot of time chasing and managing glaucoma • Screening can be done in the clinic, but having dedicated screening programs for glaucoma can hurt your cataract screening • Glaucoma in the developing world is best treated surgically because drops are expensive and compliance low • Glaucoma treatment rarely improves the vision and the disease continues to progress
Treat itching eye conservatively Like the poor , they are always with us • Encourage cold eye compresses and rinses • Use moistening drops • Avoid using steroid drops
Tarsal plate rotation surgery Training a local nurse to do the surgery in rural areas
Staff training • Consistantly train in the clinic and in surgery • Schedule dedicated training away from the work setting • Cross train the staff for maximum coverage • Incorporate spiritual mentoring and character building through example and teaching • Encourage them to take initiative. • Praise them when they do.
Train in the community • Go to communities that invite you. • Health helper - visits the families and is responsible to the committee • Village committee – chooses the committee and manage the health • Combine the eye training with regular health training • Keep things simple and clear • Immunizations, hygiene, healthy diet, visual acuity and cataract. • Minimize the emphasis on glaucoma
Equipment and supplies • Sometimes hard to get – buy locally when possible • Expensive • Needs to be maintained – have a mechanism and budget for repair • Train staff to use instruments and maintain them
light brass hammer • bending tool • 3. cotton wool • 4. 600grit diamond • file • 5 .small Arkansas stone • 6. assorted fine files • 7. mild abrasive (tooth paste) Basic repair kit
Innovation We need equipment that is: • high quality designs • Portable • Low maintenance • low cost • replaceable
Managing the finances • If possible produce glasses and eye drops locally • Support the operation of the clinic on glasses production and sales • Subsidize cataracts with the glasses and private patient fees • Build the volume with cataract surgery, low cost and high volume • Consider transporting the patients to the hospital to maximize surgeon time • Most rural surgery programs will need at least some outside funding
