Abstract
PurposeTo investigate long-term visual acuity (VA) outcomes and complication rates in vitrectomised eyes undergoing anterior chamber intraocular lens (ACIOL) insertion.Patients and methodsA single-centre, retrospective case series including all patients who had undergone ACIOL placement at the time of vitrectomy surgery or having had previous vitrectomy, between January 2007 and January 2013. Patients were identified using an electronic database and paper casefile notes were analysed for all patients. Patients were excluded if they had <3 months follow-up.ResultsTwo hundred and seventy-one patients were included in the analysis. Mean follow-up was 27 months. One hundred and forty-eight patients were vitrectomised before ACIOL placement. One hundred and twenty-three patients underwent vitrectomy at the time of ACIOL placement. Mean best-corrected visual acuity (BCVA) before ACIOL placement was 1.27 LogMar (SD 0.95). Mean BCVA at final follow-up was 0.51 LogMar (SD 0.66) (paired-sample T-test P<0.001). Forty (15%) patients developed postoperative cystoid macular oedema (CMO). Eighty-seven (32%) patients had an intraocular pressure (IOP) rise acutely post ACIOL insertion. Fifteen (6%) patients developed corneal decompensation. Five subsequently required corneal grafting. Sixteen patients had ACIOL displacement or instability requiring further surgery.ConclusionsACIOL insertion after vitrectomy is effective. Ninety-two per cent of patients maintained or gained VA, comparable to previous studies of ACIOL insertion post complicated cataract surgery. Raised IOP was the most frequent complication: 61 patients were on topical therapy at most recent follow-up. CMO tended to be acute. Corneal decompensation was infrequent.
