{Abstract}: <B>OBJECTIVE: </B>The objective of the study was to investigate possible factors influencing gas fill after microincision vitrectomy surgery (MIVS) combined with fluid-gas exchange.<BR><B>METHODS: </B>This was a retrospective chart review of patients who underwent MIVS combined with fluid-gas exchange (20% C3F8) from February 2017 to December 2017.<BR><B>RESULTS: </B>Sixty-one eyes of 58 patients were identified. The mean age was 59.97 ± 9.65 years. The mean gas fill percentage was 76.28% ± 14.29% on day 1, 65.49% ±13.65% on day 3, 60.03% ± 14.53% on day 4, and 43.9% ± 20.88% on day 7 postoperatively. Compared to phakic eyes, eyes that were pseudophakic prior to surgery had a lower gas fill on days 1-3, but the difference did not reach significance on day 3. Eyes that underwent phacovitrectomy had a significantly lower gas fill on days 1-3 than eyes that did not.<BR><B>CONCLUSIONS: </B>Postoperative pseudophakic status is associated with lower gas fill after MIVS. Adjusted gas fill should be considered in these cases.
