Difficulties in choosing the right intraocular lens in a previously vitrectomized patient - the role of the tear film.

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
We present the difficulties in choosing the right IOL, when facing a great variability of the keratometric measurements, in the case of a patient operated for epiretinal membrane and lamellar macular hole, who developed complicated cataract in the operated eye. Upon commencing the biometric measurements, inconsistency in keratometric values led to further investigations. Repeated placido disc topography initially showed corneal ectasia, which posed a problem on selecting the right type of intra-ocular lens. Ocular surface pathology was suspected, and after treatment, the topography was repeated with a Scheimpflug topographer, that showed an improved keratometric profile. The surgical solution was to implant an aspheric monofocal IOL, in the bag, with extended depth of focus that enhances intermediate vision, disregarding the previous keratometric measurements. Refractive and functional outcomes were good. In cases of biometric measurements that show inconsistency in keratometric values, ocular surface disease as well as corneal ectasia should be taken into consideration. The right implant should not be chosen based on a single measurement, but rather several measurements should be made and compared and the choice should not be made before treating the ocular surface.
