Long-term outcomes of deep anterior lamellar versus penetrating keratoplasty for keratoconus

This is a retrospective consecutive and comparative case series of keratoplasties (228 deep anterior lamellar keratoplasties (DALKs) and 274 penetrating keratoplasties (PKs)) in a single centre by one surgeon in France, between 1993 and 2021. Graft survival was 96.7% at...

Contrast sensitivity comparisons for Pelli Robson, Hiding Heidi and Double Happy tests

The authors aimed to compare contrast thresholds and measure agreement across current paediatric assessment of contrast sensitivity with Hiding Heidi and Double Happy contrast sensitivity tests vs. the gold-standard Pelli Robson chart. Reduced contrast levels were similar under different light...

Rate and predisposing factors for post-vitrectomy cataract formation in children

This study was a retrospective analysis of post-vitrectomy cataract formation in the general paediatric population. The authors aimed to determine the number of phakic children needing cataract surgery after vitrectomy surgery and related perioperative factors. The study was a 10-year...

Outcomes following repair of early-onset versus delayed-onset rhegmatogenous retinal detachments (RD) after acute posterior vitreous detachment (PVD)

This is a retrospective single centre comparative interventional study of 210 patients in total, between 2015 to 2020, presenting with delayed RD (diagnosed >42 days after initial acute PVD presentation) compared with a 2:1 age and gender-matched acute RD cohort...
