1 · What the graph read from it

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.

2 · The registry

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

purposePhacoemulsification with premium intraocular lens (IOL) implantation has been increasingly popular in the recent years. However, it is not commonly implanted in eyes who had underwent previous vitrectomy surgery as the contrast sensitivity is thought to be reduced and surgeons are worried about poor visualization of the posterior segment after implantation. Since cataract and vitreoretinal diseases often coexist, premium IOLs should be a considerable option for implantation in carefully selected cases. This study aims at reporting the postoperative near and distance visual acuity and subjective quality of vision in eyes with premium IOLs implantation and vitrectomy done.

methodsTwenty eyes with posterior vitrectomy and premium IOL implantation from 2006 to 2018 were included. Fourteen eyes were included in Group 1 with patients who underwent a combined phacovitrectomy surgery in the same setting, and six eyes were included in Group 2 with patients who received premium IOL implantation after previous posterior vitrectomy.

resultsBoth the postoperative corrected distance and near visual acuity at 1 month, 3 month and 1 year are improved in both groups. The subjective quality of vision as graded by the National Eye Institute Refractive Error Quality of Life Instrument-42 questionnaire also showed high patient satisfaction in both groups.

conclusionWe conclude that the presence of a multifocal IOL does not impede visualization of the posterior segment during vitrectomy surgery and surgical complications were not raised. With careful patient selection and preoperative assessment, premium IOLs can be a considerable option in patients requiring posterior vitrectomy.
