Abstract/Introduction

Background: Cataract is the leading cause of blindness in Malawi. We sought to determine the cataract surgical coverage and the outcome of cataract surgery in a rural district in Malawi to assess past performance of cataract surgical services.

Methods: From July to October 1999 we conducted a multistage random cluster survey to include 1630 residents aged 50 years or more in Chikwawa District. Visual acuity, cause of vision loss, history of cataract surgery and cause of poor vision (if less than 6/60) were assessed. Cataract surgical coverage, sight restoration rate and outcome were calculated by person and eye and for men and women separately.


Conclusion/Results

Results: We examined 1384 people (84.9% of target). Twenty-one people (12 men and 9 women) (30 eyes) had received cataract surgery. The cataract surgical coverage rate was 35.6% (44.4% for men and 28.1% for women [odds ratio 2.0, 95% confidence interval 0.6-7.0]) at a visual acuity level of 6/60, and 55.3% (60.0% for men and 50.0% for women [odds ratio 1.5, 95% confidence interval 0.3-6.7]) at a level of 3/60. Only one eye of one subject had received an intraocular lens. Presenting visual acuity was 6/18 or better in 7 eyes (23.3%), 6/24 to 6/60 in 7 eyes, and worse than 6/60 in 16 eyes (53.3%). Among the 16 eyes with visual acuity less than 6/60, the vision could be improved in 8 with provision of aphakic spectacles.

Interpretation: Cataract surgical coverage in this population is similar to that reported from other countries in Africa. As in other settings, cataract surgical coverage was lower in women than in men. Poor outcomes in this population are partly due to surgical complications and partly due to a lack of aphakic correction. Surgical promotion programs will need to focus on differentiating intraocular lens surgery from (previously practised) intracapsular cataract extraction surgery.


Testimonials


Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
