Ectasia Risk Model: A Novel Method Without Cut-off Point Based on Artificial Intelligence Improves Detection of Higher-Risk EyesThis study describes a new AI-based model that integrates different risk factors without a cut-off point, increasing the number of cases correctly identified as at higher risk.
Optical Assessment and Expected Visual Quality of Four Extended Range of Vision Intraocular LensesThe expected visual acuity decreased with the object distance differently, depending on the ERV design. Through-Focus Response of Extended Depth of Focus Intraocular LensesThe five EDOF lenses investigated differ mainly by their different weighting of energy between the far and intermediate ranges.

Ray-tracing Analysis of Accommodation and Pseudoaccommodation in Phakic and Pseudophakic EyesRay-tracing aberrometry can objectively assess accommodative amplitude in phakic eyes and pseudoaccommodation (depth of focus) in pseudophakic eyes.
Comparison of Astigmatic Correction With and Without Cross-axis Alignment During Small Incision Lenticule ExtractionCross-axis alignment for head positioning in SMILE significantly minimizes axis misalignment and reduces undercorrection astigmatism in myopic astigmatism correction. This technique is a non-invasive and effective method, especially for beginners. Effects of Modified Haptics on Surgical Outcomes and Rotational Stability of Toric Intraocular Lens ImplantationThe TECNIS toric II IOL with frosted haptics has significantly improved rotational stability compared to its previous model.

Leftover Astigmatism: The Missing Link Between Measured and Calculated Posterior Corneal AstigmatismLeftover astigmatism is clinically substantial. Because it is included in IOL cylinder power calculations based on refractive outcome, it may explain why methods of IOL cylinder power calculation using refractive outcome–based adjustments to anterior corneal astigmatism are more successful.
Autorefraction as an Objective Method to Evaluate Accuracy of Intraocular Lens Calculation FormulasAUTOref is a useful method with adequate accuracy to determine spherical and astigmatic outcome and equally or more effective in being able to discriminate between spherical outcome formulas. Corneal Epithelium Thickness and Refractive Changes After Myopic Laser Corneal Refractive SurgeryCorneal epithelium thickens similarly after LASIK and SMILE, being slightly higher after SMILE.
