Among 5619 SS-OCT biometer scans reviewed between 2017 and 2021, 2293 met the inclusion criteria with 1167 same-day rescans. Each scan\u2019s variables received a \u201csuccessful,\u201d \u201cwarning,\u201d or \u201cfailed\u201d result across nine biometric parameters: axial length, anterior chamber depth, central corneal thickness, keratometry, lens thickness, posterior keratometry, total keratometry, white-to-white distance, and aqueous depth. Scans achieving \u201csuccessful\u201d results for all nine variables were deemed \u201cperfect scans.\u201d Warning and failed results were analyzed separately for per-parameter analyses given their differing clinical implications for IOL power calculation.<\/jats:p>\n                  <jats:p>Results After excluding perfect initial scans, among 909 suspect sessions, only 361 (38.1%) rescans yielded better results, while 587 (61.9%) demonstrated an identical or worse outcome (95% CI: 59\u201365%, p &lt; 0.001). When analyzing all nine variables across all rescans, the subsequent scan showed an identical or worse outcome in 804 (68.9%) cases (95% CI: 66\u201372%, p &lt; 0.001). In rescans where the initial scan received a \u201cwarning\u201d or \u201cfailed\u201d result for any individual variable, 35.8\u201356.0% improved depending on the parameter. Among improved scans, mean absolute differences were minimal, suggesting limited clinical significance.<\/jats:p>\n                  <jats:p>Conclusions Repeat scans improve the quality of biometric measurements in eyes showing warning or failed results from the studied SS-OCT biometer in fewer than half of cases for most parameters.<\/jats:p>","DOI":"10.1055\/a-2948-7753","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T23:02:11Z","timestamp":1787958131000},"source":"Crossref","is-referenced-by-count":0,"title":["Comparison
