Accuracy of six contemporary toric formulas: Analysis of 6,753 Eyes

May 5, 2026

The authors aimed to compare the predictive accuracy of four toric intraocular lens (IOL) formulas integrated into the ESCRS calculator by analyzing data from 6,753 eyes. They found that the Kane formula demonstrated superior predictive accuracy, with the lowest mean vector magnitude prediction error and the highest proportion of eyes achieving errors within 0.50 D, although the clinical relevance of the small differences among the formulas remains uncertain.

Noise-Floor Benchmarking of Surgically Induced Astigmatism After Cataract Surgery: Anterior Versus Total Keratometry

May 5, 2026

The authors aimed to quantify the true surgically induced astigmatism (SIA) following cataract surgery and distinguish it from measurement variability. By comparing pre- and postoperative corneal astigmatism using standard and total keratometry, they found that a significant portion of the measured SIA overlapped with noise, indicating a modest systematic component. Their findings suggest that noise-floor benchmarking is essential for accurately interpreting SIA performance.

Evaluation of Optimised Implantable Collamer Lens Sizing using an Optical Low-Coherence Reflectometry Biometry Device at 12 months follow up

May 5, 2026

The authors aimed to determine whether a more specific white-to-white (WTW) subtraction value of 0.25mm, compared to the standard 0.4mm, could improve the sizing outcomes of Implantable Collamer Lens (ICL) surgery using the LS900 biometry device. Their findings indicated that while ideal sizing occurred in 70% of cases at 3 months, this dropped to 67% at 12 months, with a tendency for lenses to be oversized initially and undersized later. The study suggests that using a 0.25mm subtraction may help reduce the risk of low vaults, which are associated with cataract formation, but further real-world evaluation is needed to confirm these results.

Visual and Refractive Outcomes of Laser Vision Correction in Carefully Selected Patients with Diabetes Mellitus: Laser Vision Outcomes in Diabetes: A Retrospective Study

Apr 30, 2026

The study aimed to evaluate the visual and refractive outcomes of laser vision correction (LVC) techniques, specifically photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK), in adults with controlled diabetes mellitus (DM) compared to healthy controls. The findings indicated that both PRK and LASIK provided comparable safety and visual outcomes for carefully selected patients with controlled DM, suggesting that current guidelines regarding LVC in this population may be overly conservative.

A spreadsheet-based algorithm for objective assessment of depth of focus from defocus curves

Apr 27, 2026

The authors aim to develop and clinically validate a spreadsheet-based algorithm for objectively assessing the depth of focus (DoF) from defocus curves in pseudophakic eyes. Their method demonstrates high agreement with manual measurements, suggesting it effectively minimizes subjective interpretation and manual workload in DoF quantification. The study highlights the algorithm's potential for analyzing both simple and complex defocus profiles, providing a structured approach to this assessment.

Comparison of horizontal and vertical intraocular lens fixation in the flanged intrascleral haptic fixation technique

Apr 22, 2026

The authors aimed to compare the visual outcomes and safety of horizontal versus vertical intraocular lens (IOL) fixation using the flanged intrascleral haptic fixation technique. Their retrospective study found that both fixation methods resulted in similar improvements in visual acuity and other ocular parameters, although early postoperative complications, such as conjunctival hyperemia, were more prevalent in the vertical fixation group. Overall, both techniques demonstrated comparable efficacy and safety, suggesting that either fixation plane can be effectively utilized.

Size exchange and vault response in posterior chamber phakic intraocular lens implantation: 12 years at a high-volume center

Apr 22, 2026

The authors aimed to evaluate changes in vault after implantable collamer lens (ICL) exchange and identify predictors of outcomes, particularly the effects of age. They found that downsizing effectively reduced excessive vault, same-size exchange resulted in minimal changes, and upsizing increased vault but yielded smaller gains in older patients. The study highlights the importance of considering exchange strategy, preoperative vault, and patient age in ICL exchange planning.

Visual and refractive outcomes of intracapsular and add-on toric intraocular lenses in postkeratoplasty astigmatism: retrospective study

Apr 22, 2026

The authors aimed to evaluate the visual and refractive outcomes of intracapsular versus add-on toric intraocular lens (tIOL) implantation in patients with postkeratoplasty astigmatism. Their retrospective analysis of 134 eyes demonstrated significant improvements in both uncorrected and corrected distance visual acuity, as well as a reduction in refractive cylinder for both types of tIOL implantation, indicating their effectiveness in managing postkeratoplasty astigmatism.

Effect of pupillary dilation on ocular biometry and intraocular lens power calculation: prospective cohort study

Apr 22, 2026

The authors aimed to investigate how pupillary dilation affects ocular biometry and intraocular lens (IOL) power calculations in cataract surgery patients. They found that dilation caused significant biometric changes and a small myopic shift in prediction errors for IOL power calculations, although the overall predictive accuracy of modern IOL formulas remained unaffected. The study suggests that while pupillary dilation influences some measurements, it does not substantially alter the reliability of IOL power predictions.

Incidence of secondary intraocular lens implantation in school-aged children left aphakic to age 4.5 years in the Infant Aphakia Treatment Study

Apr 10, 2026

The authors aimed to determine the incidence of secondary intraocular lens (IOL) implantation in children who were left aphakic after unilateral congenital cataract surgery until age 4.5 years. The study found that 43% of participants received a secondary IOL by age 10.5 years, with significant variability in implantation rates across different clinical sites, suggesting that practice patterns and family preferences play a crucial role in the decision-making process.
