S. Ruit et al., Low-cost high volume extracapsular cataract extraction with posterior chamber intraocular lens implantation in nepal, OPHTHALMOL, 106(10), 1999, pp. 1887-1892
Objective: To improve current clinical practices and ways of thinking about
the problem of curable Third-World blindness resulting from cataract.
Design: A two-site prospective, nonrandomized, comparative clinical trial.
Participants: Patients from 2 distinct surgical venues underwent cataract s
urgery following the same carefully outlined protocol: 62 consecutive cases
from the Tilganga Eye Centre in Katmandu, Nepal, and 207 cases from a remo
te eye camp in rural Chaughada, Nepal.
Intervention: Extracapsular cataract extraction with posterior chamber intr
aocular lens (IOL) implantation surgery using a technique developed by Dr.
Sanduk Ruit of the Tilganga Eye Centre in conjunction with the Medical Dire
ctorate of the Fred Hollows Foundation of Australia. Also presented is the
teaching method used to help make local doctors proficient in this techniqu
e.
Main Outcome Measures: Visual acuity recorded at 2 months after surgery as
well as surgical complications.
Results: Preoperative visual acuities for the 62 patients from the Tilganga
Eye Centre ranged from 20/60 to light perception only (4 patients were unt
ested), At 2 months after surgery, 87.1% had a best-corrected visual acuity
of 20/60 or better. There were zero major surgical complications reported
from the Tilganga group. Of the 207 patients at the Chaughada eye camp, pre
operative visual acuities (recorded for 177 [85.5%]) ranged from 20/200 or
greater to light perception only. One hundred eighty-nine (91.3%) of the pa
tients returned for an examination at 2 months after surgery, at which time
54.5% had an uncorrected visual acuity of 20/60 or greater, improving to 7
4.1% with correction. There were six (2.9%) surgical complications document
ed at Chaughada.
Conclusions: Because the average operative time using the technique present
ed here is less than 10 minutes per case and the cost per surgery is less t
han $20, the surgical results are significant in addressing the massive pro
blem of cataract blindness in the Third World. With some changes in preoper
ative care, a simplified surgical technique, the development of local lens
factories, and the implementation of teaching programs, effective lens impl
antation cataract surgery can be done in high volume at affordable costs in
remote areas of underserved nations.
