Controversies, consensuses and guidelines on modern cataract surgery by the academy of Asia-Pacific professors of ophthalmology (AAPPO).

Phacoemulsification has revolutionized cataract surgery since its introduction by Charles Kelman in 1967, becoming the gold standard for cataract removal in most parts of the world. Despite its widespread adoption and high success rates, there exist controversies within the ophthalmic community regarding various aspects of the procedure. An international panel comprising 25 experts from 18 countries/territories was established by the Academy of Asia-Pacific Professors of Ophthalmology (AAPPO) to work on this consensus project.

Effectiveness of intraocular lenses designed to correct presbyopia after cataract surgery: an overview of systematic reviews.

This is an overview of systematic reviews to evaluate the visual outcomes of different presbyopia correcting intraocular lens (IOL), spectacle independence (SI), adverse visual effects and cost-effectiveness. Reviews were included if they compared presbyopia-correcting IOLs-such as multifocal (bifocal and trifocal), extended-depth-of-focus (EDOF), and accommodative and monofocal IOLs. The AMSTAR-2 tool was used.

Objective Versus Subjective Depth of Focus Correlation in Pseudophakic Eyes.

Purpose: To develop a method for quantifying objective depth of focus (DOF) from the visual Strehl ratio based on the optical transfer function (VSOTF), measured on a ray-tracing aberrometer (iTrace; Tracey Technologies) and to compare it to the subjective clinical DOF in two groups of pseudophakic eyes with varying asphericity of the intraocular lenses (IOLs).

Methods: In this cross-sectional study, two groups with negatively aspheric (Eyhance; Johnson & Johnson) and aspherically neutral (RayOne; Rayner) IOLs were assessed 3 to 9 months postoperatively. The patient assessments included: logarithm of the minimum angle of resolution visual acuity, refraction, defocus curves, and iTrace assessments.

Outcomes of mini-monovision with monofocal, enhanced monofocal and extended depth-of-focus intraocular lenses.

This systemic review aims to evaluate the clinical outcomes of pseudophakic mini-monovision with three types of intraocular lenses (IOLs): monofocal, enhanced monofocal, and extended depth of focus (EDOF).

Methods: A comprehensive literature search was conducted using PubMed and MEDLINE to identify studies reporting mini-monovision outcomes within the three categories of IOLs up to July 2024.

Corneal Allogenic Intrastromal Ring Segments: A Literature Review.

Corneal allogenic intrastromal ring segments (CAIRSs) offer a novel, biocompatible alternative to synthetic intracorneal ring segments (ICRSs). This review aims to evaluate the clinical outcomes of CAIRS. Inclusion criteria were studies with a minimum of 20 eyes and six months of follow up.

Temporary tectonic posterior corneal lamellar graft without Descemet's stripping for ab-interno sealing of large corneal perforation in severe dry eyes.

Managing large corneal perforations in severe dry eye disease (DED) is often challenging. We describe such a case that was successfully managed with a temporary tectonic posterior corneal lamellar graft. A patient with Sjogren's syndrome presented with filamentary keratitis and was inappropriately prescribed G.

Relationship of Angle Kappa with Ocular Parameters using Swept-Source Ocular Coherence Tomography in Cataract Surgery Patients.

Purpose: To assess the relationship between angle kappa (apparent chord mu) and ocular parameters in cataract patients.

Methods: In this cross-sectional study, the data on apparent chord mu, age, axial length, anterior chamber depth, anterior and posterior mean keratometry, mean total keratometry, white-to-white, central corneal thickness and lens thickness were collected for consecutive cataract patients. Correlation (Pearson) between chord mu and the other ocular parameters was calculated.

Bilateral Urrets-Zavalia syndrome after uneventful Descemet membrane endothelial keratoplasty.

Urrets-Zavalia syndrome (UZS) stands out as a rare yet clinically consequential complication associated with ophthalmic surgery, marked by the emergence of a fixed and dilated pupil. While it was originally described post-penetrating keratoplasty (PKP) in patients with keratoconus and its prevalence is notably higher following PKP, instances of UZS have been documented in the context of other procedures, including intraocular lens implantation, Descemet-stripping endothelial keratoplasty and Descemet membrane endothelial keratoplasty (DMEK). We report a unique case of bilateral UZS after uneventful DMEK surgeries, highlighting a rare but potential complication after DMEK.

Transepithelial Photorefractive Keratectomy-Review.

The type and nature of refractive surgery procedures has greatly increased over the past few decades, allowing for almost all patient populations to be treated to extremely high satisfaction. Conventional photorefractive keratectomy involves the removal of the corneal epithelium through mechanical debridement or dilute alcohol instillation. An improvement to this method utilises laser epithelial removal in a single-step process termed transepithelial photorefractive keratectomy (transPRK).
