Setting.—Stoke Mandeville Hospital, Aylesbury, Buckinghamshire, United Kingdom. Methods.—This prospective randomized observer-masked study comprised 100 patients who had routine phacoemulsification by the same surgeon at a district general hospital in the United Kingdom. The postoperative changes in capsulorrhexis apertures and anterior capsule opacification (ACO) between Group A (aspiration of LECs) and Group B (control) were compared. Digital retroillumination images of the capsulorrhexis aperture were taken 1 week and 3 months postoperatively. The area of capsulorrhexis aperture was determined with computer software, and capsule opacification was graded subjectively. Results.—Three months postoperatively, the mean decrease in capsulorrhexis aperture was 1.9% in Group A and 5.6% in Group B (P ⫽ .02). The ACO at 3 months was grade 2 in 44% of eyes in Group A and in 61% in Group B (P ⫽ .13). Conclusion.—Aspiration of LECs from the anterior capsule was a safe procedure that reduced capsulorrhexis aperture contraction 3 months after cataract surgery. 䉴 This is yet another article that examines the effect of aspiration of lens epithelial cells from the underside of the anterior capsule. This article studies a different long-term effect of this maneuver and demonstrates that it leads to reduced contraction of the capsulorrhexis aperture. Theoretically, this should help lead to long-term intraocular lens stability. This consequence of the technique of anterior capsule polishing should be considered when surgeons are considering whether to incorporate this into their surgical technique. R.
