BCLA CLEAR Presbyopia: Evaluation and diagnosis.

It is important to be able to measure the range of clear focus in clinical practice to advise on presbyopia correction techniques and to optimise the correction power. Both subjective and objective techniques are necessary: subjective techniques (such as patient reported outcome questionnaires and defocus curves) assess the impact of presbyopia on a patient and how the combination of residual objective accommodation and their natural DoF work for them; objective techniques (such as autorefraction, corneal topography and lens imaging) allow the clinician to understand how well a technique is working optically and whether it is the right choice or how adjustments can be made to optimise performance. Techniques to assess visual performance and adverse effects must be carefully conducted to gain a reliable end-point, considering the target size, contrast and illumination.

Novel Management of Ocular Surface Inflammation in Patients With Ocular Graft-Versus-Host Disease in the Setting of Cataract Surgery.

Purpose: To report the outcomes of cataract surgery in patients with ocular graft-versus-host disease (oGVHD) using a novel preoperative immunomodulatory regimen in a collaborative subspecialty care setting.

Methods: Retrospective case series of patients with oGVHD who underwent cataract surgery using a novel preoperative immunomodulatory regimen in a collaborative care setting. A preoperative regimen consisting of pooled human immune globulin 1%, autologous serum 50%, and methylprednisolone 1% eye drops was prescribed.

Subclinical Keratoconus Detection and Characterization Using Motion-Tracking Brillouin Microscopy.

Purpose: To characterize focal biomechanical alterations in subclinical keratoconus (SKC) using motion-tracking (MT) Brillouin microscopy and evaluate the ability of MT Brillouin metrics to differentiate eyes with SKC from normal control eyes.

Design: Prospective cross-sectional study.

Participants: Thirty eyes from 30 patients were evaluated, including 15 eyes from 15 bilaterally normal patients and 15 eyes with SKC from 15 patients.

Motion-Tracking Brillouin Microscopy Evaluation of Normal, Keratoconic, and Post-Laser Vision Correction Corneas.

Purpose: To characterize focal biomechanical differences between normal, keratoconic, and post-laser vision correction (LVC) corneas using motion-tracking Brillouin microscopy.

Design: Prospective cross-sectional study.

Methods: Thirty eyes from 30 patients (10 normal controls [Controls], 10 post-LVC, and 10 stage I or II keratoconus [KC]) had Scheimpflug and motion-tracking Brillouin microscopy imaging using a custom-built device.

The Most Cited Articles and Authors in Refractive Surgery.

Purpose: To provide a comprehensive analysis of the most highly cited articles and authors in refractive surgery.

Methods: The Scopus database was searched for articles pertaining to refractive surgery using multiple search terms to identify the top 100 most cited articles in refractive surgery. A publicly available database of more than 100,000 scientists that provides standardized information on multiple variables resulting in a composite indicator (C score) was searched to identify refractive surgery authors.

Comparison of Visual Outcomes and Patient Satisfaction After Bilateral Implantation of an EDOF IOL and a Mix-and-Match Approach.

Purpose: To evaluate visual outcomes at different distances (near, intermediate, and far), depth of focus, optical quality, quantitative dysphotopsia, and patient satisfaction in two groups.

Methods: The extended depth of focus (EDOF) only group (n = 40 eyes) was implanted bilaterally with an EDOF intraocular lens (IOL) and the mixed group (n = 40 eyes) was implanted with the same EDOF IOL in the dominant eye and a trifocal IOL in the fellow eye. At the 3-month postoperative visit, refractive outcomes and monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance visual acuities for far UDVA, CDVA, distance-corrected intermediate visual acuity (DCIVA) at 80 cm, uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA) at 40 cm, and binocular defocus curve were evaluated.

Outcomes of combining a trifocal and a low-addition bifocal intraocular lens in patients seeking spectacle independence at all distances.

Purpose: To assess the visual and refractive outcomes and patient satisfaction after cataract surgery in patients with a diffractive multifocal intraocular lens (IOL) with a low addition (add) power (+2.75 diopters [D]) (Tecnis ZKB00) in the dominant eye and a diffractive trifocal IOL (AT LISA tri 839MP) in the nondominant eye.

[Clinical Evaluation of a Novel Intraocular Lens with Enhanced Depth of Focus (EDOF) to Increase Visual Acuity for Intermediate Distances].

Background: Modern intraocular lens surgery has made great progress over the last few years towards creating independency of spectacles in daily life. Especially in the areas of distant and near visual acuity, optimisation has been possible. Nevertheless, with new media and requirements in professional life, there is an increasing need for optimisation of the intermediate range.
