Outcomes of cataract surgery in patients with previous corneal transplantation for keratoconus: comparison of PK and DALK.
Article in International ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo evaluate the visual and refractive outcomes of cataract surgery in patients with previous deep anterior lamellar keratoplasty (DALK) or penetrating keratoplasty (PK) performed for keratoconus.
methodsThis cross-sectional study evaluated patients with a history of corneal transplantation who underwent cataract surgery. Corrected distance visual acuity (CDVA) and manifest refraction were assessed postoperatively. Pre- and postoperative outcomes were compared using paired t-tests and Wilcoxon signed-rank tests, while intergroup (PK vs. DALK) differences were analyzed using independent t-tests and Mann-Whitney U tests. Finally, multivariable linear regression analysis was performed to adjust for potential confounding variables.
resultsA total of 24 eyes from 24 keratoconus-affected patients were included, comprising 12 patients in each of the DALK and PK groups. Following cataract surgery, CDVA, spherical refractive error, and spherical equivalent (SE) showed significant improvement (p = 0.023, < 0.001, and < 0.001, respectively), while cylindrical refractive error remained unchanged (p = 0.943). Patients in the DALK group demonstrated better CDVA compared to those in the PK group (p = 0.028), a difference that remained significant after adjusting for confounders (p = 0.004). However, refractive outcomes, including spherical refractive error, cylindrical refractive error, and SE did not differ between the two groups (p = 0.127, 0.247 and 0.347, respectively). Graft survival was excellent in both groups at final follow-up.
conclusionAlthough the sample size is small, the results of this study show that cataract surgery yields favorable visual and refractive outcomes in post-keratoplasty patients, with superior results observed in DALK cases compared to PK.
