Reading Performance Following Contralateral Implantation of an Extended Depth of Focus (EDOF) IOL and a Hybrid EDOF Multifocal IOL.

Purpose: To assess objective reading performance at intermediate and near distances using the Salzberg Reading Desk (SRD) (SRD Vision) in patients with cataract who underwent the implantation of a diffractive extended depth of focus intraocular lens (EDOF IOL) in the dominant eye and a hybrid multifocal EDOF IOL in the non-dominant eye.

Methods: This prospective, non-comparative, interventional study included 46 eyes of 23 patients with cataract who underwent bilateral cataract surgery with implantation of the DFR00V Tecnis Synergy IOL (Johnson & Johnson Surgical Vision) in the non-dominant eye and the DXR00V Tecnis Symfony OptiBlue IOL (Johnson & Johnson Surgical Vision) in the dominant eye. At postoperative 6 months, the Salzburg Reading Desk was used to assess distance-corrected reading performance at near and intermediate distances.

Prospective Evaluation of Clinical and Patient-Reported Outcomes Following Contralateral Implantation of an Extended Depth of Focus (EDOF) and Hybrid EDOF-Multifocal IOL.

Purpose: To evaluate clinical outcomes following contralateral implantation of a diffractive extended depth of focus (EDOF) and a hybrid EDOF-multifocal intraocular lens (IOL) with a violet filter in a U.S.-based population.

Prediction of the small aperture intraocular lens on visual acuity in patients with keratoconus.

Purpose: To investigate the impact of corneal higher-order aberrations (HOAs) on predicted corrected distance visual acuity (CDVA) in patients with keratoconus at varying simulated pupil apertures.

Setting: Ophthalmology Clinics, Medical University of South Carolina, Charleston, South Carolina.

Design: Retrospective chart review study.

Anterior segment reconstruction due to cosmetic iris implants placed in the anterior chamber.

A 27-year-old woman had BrightOcular iris implants placed for cosmetic purposes that changed eye color from brown to blue bilaterally. Of note, BrightOcular implants are not approved by the U.S.

Possible Sampling Error in Corneal Specular Microscopy: Can Central Endothelial Data Generated by Specular Microscope Represent the Real Clinical Condition of the Whole Cornea?

Purpose: To estimate the minimum number of cells required to obtain reliable data in a specular microscope, which could possibly represent the real clinical condition of the corneal endothelium.

Methods: A cross-sectional study of 122 eyes of 61 individuals submitted to noncontact specular microscope was conducted. Data generated by the manufacturer's software were uploaded to specific statistical software for sampling relative error calculation.

[Reliability of predictable postoperative visual acuity of cataracts as measured by Heine Lambda 100 retinometer preoperatively].

Purpose: To assess the relationship between potential visual acuity obtained before cataract surgery using Heine Lambda 100 retinometer with best corrected visual acuity 3 months postoperatively, as well as its correlation with the morphological pattern of the dominant cataract and the intensity of nuclear opacification.

Methods: Prospective study executed in the Ophthalmology Hospital Laser Vision in Santos of 121 eyes of 70 patients who underwent cataract surgery (phacoemulsification with intraocular lens implantation), from April to July, 2009. In the preoperative period, Heine retinometer test was performed under mydriasis and its results were compared to postoperative best corrected visual acuity three months after surgery and correlated with the morphological classification of cataracts, being considered a satisfactory result those who did not vary more than two lines in Snellen chart.
