Purpose: To evaluate optimal standard intraocular lens power for Nepalese eye camp cataract patients Methods: Retrospective case-series of 5109 consecutive pre-operative cataract patient files at Tilganga Eye Center studied. Age, sex, K1, K2, axial length and IOL power used in these patients was analyzed. Results: The mean axial length was 23.078 with a standard deviation of 1.259 and a mode of 22.84. IOL diopter mean was 21.3651 with a standard deviation of 3.04 and a mode of 22. K1-K2 mean was 0.288 with a mode of 0.5. Conclusions: The currently used single power IOL used at the Tilganga Eye center in Nepal leaves a majority of patients hyperopic. An increase in the power of IOL used for cataract patients at Nepalese eye camps would provide a better visual outcome for more patients. A single IOL with a power of 22.5D, rather than the currently used 21.0D, would also leave more patients without post-operative hyperopia. This data could likely be used at other eye camps to improve visual outcomes for patients in developing countries and remote operative locations.
