Median age was 67.4 (interquartile range [IQR] 27– 89) years. Thirty-two (31.1%) had subluxated cataracts, while 71 (68.9%) had subluxated IOLs. Overall median preoperative logMAR BCVA was 0.9 (IQR 0– 2.5). Median logMAR BCVA improved to 0.3 (0– 1.9) and 0.2 (0– 1.8) for the subluxated cataract and IOL groups, 81.2% and 75% of eyes achieved logMAR ≤ 0.3, and 94% and 97% achieved IOL stability at month 12, respectively. Eyes with subluxated IOLs had a significantly less myopic median SE if a new IOL was implanted compared to iris-fixating the dislocated IOL.Conclusion: Combined primary TPPV and IF-PCIOL implantation is a good surgical option for subluxated IOL or cataract without sufficient capsular support, with at least 75% achieving logMAR BCVA ≤ 0.3 and 95% IOL stability at postoperative year 1. In eyes with subluxated IOLs, explanting that IOL and iris-fixating a new IOL led to a reduced SE and better visual outcome at postoperative month 12 when compared to iris-fixating the dislocated IOL.Keywords: subluxated cataracts, subluxated intraocular lenses, secondary intraocular lens fixation, iris-fixation, trans pars plana vitrectomy |
