We compared rates of intraocular lens (IOL) decentration, neodymium-doped yttrium aluminum garnet capsulotomy for posterior capsule opacification (PCO), and visual acuity (VA) in eyes with and without pseudoexfoliation (PEX) 5 years after undergoing cataract surgery. Prospective comparative interventional study. This multicenter study population included 1 eye of both 930 cataract patients with and 470 cataract patients without uncomplicated PEX (no small pupils or phacodonesis) all undergoing phacoemulsification by experienced Aravind Eye Care System surgeons. Eyes were randomized to either 1- or 3-piece intraocular lenses (IOLs). PEX eyes were also randomized to either receive or not receive a capsule tension ring. The main outcome measures included IOL decentration and PCO. Secondary outcomes included postoperative best-corrected VA. Follow-up was 86.2% in the PEX group and 86.7% in the control group at 5 years. The PEX group was older (P < .001) and had more men (P = .01). IOL decentration at 5 years was equally prevalent in PEX and control eyes (1.0% vs 1.1%, respectively, P = .8). Neodymium-doped yttrium aluminum garnet posterior capsulotomy rates for PCO were similar in the PEX group when compared with control subejcts (5.3% compared with 3.2%, respectively, P = .07). Best corrected VA was better at baseline and years 2 and 3 in the control group (P = .0001, P = .0005, and P = .02); however, there was no difference in BCVA at years 1, 4, and 5 between the PEX and control groups (P = .09, P = .29, and P = .5). In a large-scale, long-term, prospective comparative study of cataract surgery in eyes with uncomplicated PEX, the risks of IOL decentration and PCO were low and comparable to that in control subjects. When approaching cataract surgery in eyes with relatively uncomplicated PEX, neither IOL choice (1- vs 3-piece acrylic IOL) nor the presence/absence of a capsule tension ring affects outcomes at 5 years.
