Neither outpatient surgery nor intraocular lenses have been widely used in
developing countries. We performed extracapsular cataract extraction with
posterior chamber intraocular lens implantation in a simple outpatient
clinic in Ghana, West Africa. Forty-nine (64%) of 77 eligible patients with
follow-up times of 12 to 29 months after surgery underwent an eye
examination and an interview related to activities of daily life.
Preoperative visual acuity was counting fingers or worse in all but one
patient. Visual acuity improved in 44 patients (90%) after surgery.
Twenty-six patients (53%) had a corrected visual acuity of 20/40 or better,
11 (22%) had a corrected visual acuity of 20/50 to 20/100, and 12 (25%) had
a corrected visual acuity of 20/200 or worse. Subjectively, 94% of patients
believed that their vision improved after surgery. No major late
complications occurred following the immediate postoperative period. In
addition, our population experienced no complications attributable to the
outpatient format of this surgery. Every patient, all of whom lived within
a 32-km radius of the clinic, reliably returned for postoperative
appointments. Our results demonstrate that outpatient surgery may be a safe
and practical alternative to routine hospitalization for eye surgery in
developing countries.
