Sutureless Extracapsular Cataract Extraction with intraocular lens implantation
Transcript of Sutureless Extracapsular Cataract Extraction with intraocular lens implantation
What Can You Get For $20?
Let me share with you some perspective
Up to 80% of the world's blindess is avoidable.
Avoidable blindness is defined as blindness which could be either treated or prevented by known, cost-effective means. Although there are many other causes of vision impairment, VISION 2020 seeks to address the main causes of avoidable blindness, in order to have the greatest possible impact on vision loss worldwide.
18 million people blind
So which is really better to tackle avoidable blindness?
108 patients with cataracts randomly assigned to have phacoemulisification or sutureless extracapsular extraction
Phacoemulsification done by Dr. David Chang
WHO defines visual impairment at worse than 20/60 (unaided)
"temporal clear corneal incision that was fashinoned with a diamond keratome"
Two groups showed no statistically significant differencec in corrected or uncorrected visual acuity after 6 months (p=.30)
Initial visual recovery with SICS: 50% had 20/30 or better vs. 30% in phacoemulsification at day 1 ( p<.028)
SICS: 15 USD
Phaco: 70 USD (lens, tyrpan blue dye, tips, sleeves, test chambers, infusion liquid)
PMMA: 5 USD
foldable acrylic IOL: 52 USD
Average Surgery Plus Turnover Time:
Phacoemulsification: 15.5 minutes
SICS: 9.0 minutes
SCIS: Cheaper, Faster, Less Technological Overhead/Logistics, Operationally Similar Vision
