An eyedrop called Upneeq is the first drug approved by the United States Food and Drug Administration to treat acquired ptosis, a condition where the upper eyelid droops over the eye.

Posterior capsule rupture (PCR) rates are used to measure cataract surgeons’ quality. We wished to evaluate the internal non-visible surfaces of metal irrigation/aspiration (I/A) tips to identify potential mechanisms for PCR via novel metallographic imaging. Ten metal I/A instruments underwent metallographic preparation by fine sectioning to expose inner surfaces near the aspiration opening. Analysis of inner bore, lumen, and opening aperture of metal aspiration tips was performed by optical microscopy, scanning electron microscopy (SEM), and 3D volume X-ray computational tomography (XCT). Distances from external aperture to first sharp metal surface were obtained and compared with a silicone-tipped instrument. We identified metal burrs near the aspiration apertures and manufacturing defects within all tips. XCT confirmed optical and SEM findings of significant defects and metal irregularities within aspiration tips. Samples also showed variation in lumen size/thickness, rough surfaces and material inhomogeneity, most pronounced at the internal tip. Median distance from outer aperture opening to first metal burr was 30 microns (range 10–120) and to internal tip irregularity (manufacturing flaw) was 250 microns (range 100–350). By comparison, distance to metal from the silicone outer aperture opening was 850 microns. We have demonstrated the hidden sharp metallic irregularities within commonly used metal I/A tips. If an aspirated capsule encounters these sharp metal flaws, PCR could result. Minimising this risk would require lengthening potential distance between capsule and bare metal (as with polymer/silicone tips). Our study provides unique imaging evidence endorsing this principle and illustrates a hidden mechanism contributing to PCR.

To present the visual acuity (VA) results and complication rates following Artisan intraocular lens (IOL) insertion in vitrectomised eyes. Outcome data were collected for all vitrectomised patients who had undergone Artisan IOL insertion between January 2014 and May 2019 at Moorfields Eye Hospital. All those with follow-up greater than 2 months were included in the analysis. Sixty-nine eyes from 61 patients were included. Average follow up was 2 years. Fifty-five (80%) eyes had at least one ocular comorbidity prior to Artisan IOL insertion. At final follow up 46 (67%) eyes had best-corrected VA better than 6/12. Sixty-three eyes (91%) either gained or maintained VA. Mean post-operative spherical equivalent was −0.2D. Two (3%) lenses became de-enclavated requiring further surgery. Two (3%) eyes developed acute post-operative cystoid macular oedema. Two (3%) required additional topical IOP-lowering therapy to their pre-operative glaucoma regimen. One eye had mild corneal oedema, which persisted for 1 year following surgery and subsequently resolved. Artisan IOL insertion is a safe and effective option for the surgical correction of aphakia in vitrectomised eyes lacking capsular support. Refractive results comparable to posterior chamber IOL placement can be achieved with these lenses.

To evaluate eye rubbing and sleeping position in patients with Unilateral or Highly Asymmetric Keratoconus (UHAKC). Case-control study of consecutive UHAKC patients diagnosed at the Rothschild Foundation. Controls were age- and sex-matched, randomly selected refractive surgery clinic patients. Patients self-administered questionnaires regarding their family history of keratoconus, eye rubbing, and sleeping habits. All the eyes underwent a comprehensive ocular examination. Logistic regression was used to analyze univariate and multivariate data to identify risk factors for keratoconus. Thirty-three UHAKC patients and 64 controls were included. Univariate analyses showed that daytime eye rubbing [OR = 172.78], in the morning [OR = 24.3], or in eyes with the steepest keratometry [OR = 21.7] were significantly different between groups. Allergy [OR = 2.94], red eyes in the morning [OR = 6.36], and sleeping on stomach/sides [OR = 14.31] or on the same side as the steepest keratometry [OR = 94.72] were also significantly different. The multivariate model also showed statistical significance for most factors including daytime eye rubbing [OR = 134.96], in the morning [OR = 24.86], in the steepest eye [OR = 27.56], and sleeping on stomach/sides [OR = 65.02] or on the steepest side [OR = 144.02]. A univariate analysis in UHAKC group, comparing the worse and better eye, showed that eye rubbing [OR = 162.14] and sleeping position [OR = 99.74] were significantly (p < 0.001) associated with the worse eye. Our data suggests that vigorous eye rubbing and incorrect sleeping position are associated with UHAKC. This is especially true in rubbing the most afflicted eye, and contributory sleep position, including positions placing pressure on the eye with the steepest keratometry.
