Effect of Timing of Pars Plana Vitrectomy on Visual Outcome in Cases of Nucleus Drop during Phacoemulsification.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe purpose of the study was to study the relationship between the timing of pars plana vitrectomy (PPV) with corrected distance visual acuity (CDVA) in cases of nucleus drop during phacoemulsification.
methodsThis retrospective analysis included 83 patients, who underwent PPV for nucleus or nuclear fragment drop from July 2017 to November 2019. Timing of PPV (≤2 weeks and >2 weeks) after the primary cataract surgery was noted. The primary endpoint was CDVA at 1 month, which was compared with the time of PPV. Visual outcome was assessed as good if CDVA was better than or equal to 20/40 and poor if CDVA was worse than 20/40. Mode of management along with type of secondary intraocular lens (IOL) implanted was also evaluated.
resultsOut of the 83 cases (55 males and 28 females) in which vitrectomy for nucleus drop was performed, 36 cases were operated within 2 weeks and 47 were operated between 2 weeks and 1 month. In cases which were operated within 2 weeks, CDVA of 20/20-20/40 was achieved in 33 cases. For those who were operated on after 2 weeks, CDVA of 20/20-20/40 was achieved in 43 cases. The difference in visual outcome in both the groups was statistically nonsignificant (Fisher's exact
conclusionTiming of intervention has no bearing on the final visual outcome after vitrectomy in cases of nucleus drop during phacoemulsification. The continuity of the capsulorrhexis and the availability of capsular support determines the type of placement of the lens. A foldable lens can be placed in the sulcus if continuous capsulorrhexis is present.
