Abstract

Problem statement: Biometry is crucial for good outcomes. Only 20% of patients undergoing cataract surgery in Karamoja subregion were having biometry done.

Methods: We collected secondary data on Snellen visual acuity pre and post operatively and after one week follow up and entered it into Microsoft excel spreadsheet for analysis and presentation using tables [Figure 1].

Results: A total of 418 surgeries were carried out in the months of March, April, September and October 2022 in Southern Karamoja. Of these, 252 (60.3%) were done with biometry and 166 (39.7%) using standard Intra Ocular Lenses (IOLs). 167 (39.2%) of the patients were males and 251 (60.0%) were females. The age group ranged from 35-95.

Of the 166 eyes operated using standard Intraocular lenses, 83 (50%), 71 (42.8%) and 12 (7.2%) had good, borderline and poor outcomes respectively on the first postoperative day without correction. After one week, 140 (84.3%) were available for review while 21 (13%) were lost to follow-up. Of those reviewed, 90 (64.3%), 41 (29.3%) and 10 (7.1%) had good, borderline and poor outcomes respectively.

Of the 252 eyes that had biometry done before surgery, 122 (48.4%), 103 (40.9%) and 27 (10.7%) had good, borderline and poor outcomes respectively on the first postoperative day without correction. After correction with pinhole, 177 (70.2%), 49 (19.4%) and 26 (10.3%) had good, borderline and poor outcomes respectively. 184 (73%) eyes were reviewed after one week while 68 (27.1%) were lost to follow-up. Of the 184 reviewed, 140 (76.1%), 39 (21.2%) and 4 (2.2%) had good, borderline and poor outcomes respectively without correction.

Conclusion: There was an overall improvement in visual outcomes in eyes that had biometry done. The findings also drew attention to the difference in visual outcomes in the immediate postoperative period and after one week follow-up with the latter probably due to improvement in postoperative pain and adjustment to the intraocular lens.
