Visual outcomes and astigmatism after sutureless, manual cataract extraction in rural China


 

 

A recent study of the visual acuity and astigmatism of persons undergoing cataract extraction by local surgeons in rural China confirmed the efficacy of skill transfer, with superior outcomes to most studies in rural Asia. Dennis S.C. Lam, M.D., chairman, Department of Ophthalmology & Visual Sciences, The Chinese University of Hong Kong, published the study results in the October issue of Archives of Ophthalmology.

For the study, researchers measured visual acuity, keratometry, and refraction 10 to 14 months post-op for all cataract cases during four months in Sanrao, China. Among 313 eligible subjects, 242 (77%) could be contacted, of whom 176 (73%) were examined, and 85.2% had a pre-op presenting visual acuity of 6/60 or worse.

Presenting and best-corrected post-op acuity were 6/18 or better in 83.4% and 95.7%, respectively. Among 27 fellow eyes operated on elsewhere, 40.7% had a presenting acuity of 6/18 or better and 40.7% were blind (P< 0.001). Mean ± standard deviation (SD) post-op astigmatism did not differ between 211 eyes that were operated on (–1.13 ± 0.84 D) and 109 eyes that were not (–1.13 ± 1.17D; P= 0.27). Presence of operative complications (8.5%) and older age were associated with worse vision; bilateral surgery was associated with better vision, Dr. Lam concluded.
