Power and Precision: The New Era of Phacoemulsification TechnologyModern phacoemulsification technology has evolved into a precise, efficient, and customizable system that supports both standard cataract surgery and refractive visual outcomes. Contemporary devices integrate intelligent fluidics, responsive energy delivery, and enhanced intraoperative control, aiming to improve safety and reduce corneal trauma. Femtosecond laser platforms contribute by standardising capsulotomies, fragmenting the nucleus, and enabling astigmatism-neutral corneal incisions, which supports predictable refractive results and facilitates the use of advanced IOL designs. Astigmatism management remains central to postoperative quality, with digital marking systems improving axis alignment and complementing toric IOL implantation. Sustainability is gaining relevance as reusable tubing, cassettes, and blades reduce environmental burden without compromising safety. Across these domains, innovation focuses on precision, patient-centred refractive planning, and resource-conscious implementation. The new era of phacoemulsification combines technological refinement, optical optimisation, and sustainable strategy to advance cataract surgery outcomes.Bridging Cornea and Lens: The Modern Role of Phakic IOLs in a Myopic WorldPhakic intraocular lenses provide a valuable refractive option for patients with myopia extending beyond the safe limits of corneal laser procedures. Positioned either in the anterior or posterior chamber, they preserve the natural crystalline lens and maintain corneal structure, making them particularly suitable when optical quality, contrast vision, or biomechanical stability must be prioritised. Current guidelines support their use from low to high myopic ranges, with toric designs enabling simultaneous astigmatism correction. Compared with laser-based approaches, phakic IOLs deliver strong visual performance and high patient satisfaction, especially in moderate and high myopia. Long-term outcomes highlight the need for monitoring endothelial cell behaviour and cataract formation as part of routine follow-up. When cataract develops later in life, bilensectomy combines IOL explantation with cataract surgery to preserve refractive goals. Phakic IOLs bridge the space between corneal and lenticular refractive strategies and remain central in modern myopia management.From Awareness to Action: Stepwise Learning to Manage Capsular Rupture During Cataract SurgeryPosterior capsular rupture remains a decisive intraoperative challenge during cataract surgery, most often occurring during lens removal, cortical aspiration, or IOL implantation. Successful management requires early recognition, maintenance of chamber stability, and prevention of nuclear descent into the vitreous. This work presents a structured escalation strategy guiding surgeons from awareness of risk factors to practical intervention. Key steps include controlled viscoelastic support, careful manipulation of remaining lens material, and appropriate anterior or pars plana vitrectomy when vitreous prolapse occurs. IOL selection must be adapted to capsular integrity, allowing placement in the bag when stable or in the sulcus with or without optic capture when support is limited; alternative fixation methods remain essential fallback options. Case examples illustrate that even multifocal IOL implantation is achievable despite rupture if capsular support is preserved and decision-making remains systematic. The stepwise approach aims to enhance intraoperative safety, reduce complication impact, and preserve refractive goals in modern cataract surgery.

Divide and Conquer: Establishing a Stable Foundation for BeginnersThe divide and conquer technique is the fundamental method that every cataract surgeon begins their training with. The divide and conquer phacoemulsification technique involves several steps. First, a proper capsulorhexis and excellent hydrodissection are performed to ensure the nucleus can be rotated freely. Next, the surgeon creates a deep groove and then cracks the nucleus into four quadrants. Finally, the nucleus is emulsified and aspirated piece by piece. Pearls for this method include deeply debulking the nucleus before cracking, ensuring all pieces are broken up before removal to facilitate easier rotation and extraction, and having strategies for managing both soft and hard cataracts.

Chopping Strategies: Horizontal, Vertical, Prechop, and BeyondThe "Phaco Chop" techniques—Horizontal, Vertical, and Prechop—are advanced surgical strategies used in phacoemulsification to fragment the eye's cloudy lens nucleus. The goal of all chop techniques is to reduce the amount of ultrasound energy and time needed for removal, which minimizes damage to the corneal endothelium and other ocular structures. Phaco Chop leads to significant surgical benefits including (1) Minimized Zonular Stress: By stabilizing the nucleus with the phaco tip and applying opposing forces centripetally, the stress transmitted to the delicate zonules is drastically reduced compared to the grooving required in the "Divide and Conquer" technique. (2) Reduced Phaco Power & Time: Replacing the need to sculpt trenches with mechanical cleavage saves ultrasound energy and shortens the overall procedure time. (3) Safety in Challenging Cases: Small Pupils: The technique keeps all major movements contained within the central 3–4 mm of the pupil, avoiding the need to work under a small iris. (4) Dense Cataracts: Vertical chop, in particular, can efficiently split hard, brunescent nuclei that would otherwise require excessive, damaging ultrasound energy. In short, Phaco Chop is an elegant solution in cataract surgery that leverages the physical properties of the lens (cleavage planes) to substitute energy-intensive destruction with controlled, mechanical fragmentation, resulting in a safer, faster, and less traumatic operation for the eye. Beyond the basic Horizontal and Vertical Phaco Chop techniques, various advanced and hybrid strategies have also evolved in cataract surgery to improve safety, efficiency, and adaptability for different cataract types and eye conditions.

Phacoemulsification: Challenging and Interesting CasesPhacoemulsification in complex cases is always challenging. Situations such as hard nucleus, intumescent cataract, posterior polar cataract, loose zonule, or small pupil require special surgical techniques to overcome the difficulties. In some patients, multiple complexities may occur simultaneously, making the procedure extremely challenging—sometimes described as a surgeon’s nightmare.
This presentation will highlight selected interesting cases and demonstrate strategies to manage them safely, guiding surgeons on how to navigate through these “war zone” scenarios with confidence.Challenges in Soft Nucleus: Don’t Drown in Shallow WaterPhacoemulsification in soft nuclei can be challenging if inappropriate techniques are used. The soft nature of the nucleus makes nuclear disassembly difficult. Chopping and rotation are not easily performed because the chopper tends to cut through the nuclear mass when cracking or rotational force is applied, without achieving satisfactory results. The phaco tip also cannot hold the nucleus firmly enough during chopping or pulling.
“Stab Test” using a 27g. hydrodissection canular to determine the hardness of the nucleus before performing hydrodissection is essential, in order to choose the most appropriate phaco technique.
Special techniques such as Hydro Subluxation + Aspiration, Hydro Subluxation + Flip & Chop, Half Bowl + Rim Aspiration, and Chip & Flip (I. Howard Fine) will be discussed, including phacodynamics for soft nuclei.
When proper techniques are applied, surgery can be performed safely and effectively.

Refractive cataract surgery to correct and eliminate presbyopia to achieve better vision in patients undergoing cataract surgerySynopsis Refractive cataract surgery is now replacing standard high-volume, low-cost cataract
surgery with monofocal IOL implantation. The possibility is to correct refractive defects, myopia,
hyperopia and astigmatism and overcome presbyopia limitations. It is necessary to change the
preoperative patient procedures and manage Meibomian gland dysfunction in cataract patients.
Normally three treatments should be applied: BlephEx (Alcon) to eliminate Demodex blepharitis
Biofilm and to open glands duct LipiFlow (J&J) to get postoperative refractive emmetropia. In this
course, we will review state-of-the-art knowledge on refractive cataract surgery in pursuing highly
satisfactory uncorrected distance, intermediate and near vision. Routine dry eye management will
be discussed. Advanced biometry, multiple shots and new procedures will be explained and
demonstrated .The new technical model for the adoption of refractive cataract surgery: biometry evaporative dry eye pupil-dependent trifocal IOLsSynopsis PRESENTATION will certify as postoperative precise IOL power detection is based on quality of
tear film to provide cornea smooth surface.Improvements . Multiple biometry exams are needed
until refractive IOLs power stabilization
Objective The MAPRY/clear oil protocol is based on consecutive session with three phisical
treatments. First treatment applied is Blephex(LLC) to remove Demodex, Biofilm and to unclog
excretory channels of the meibomian glands Second Treatment,LipiFlow (J&J),replaces occlusions
of the MG warming the material responsible of MGD improving a solid sttatification into the liquid
state easier to remove. ILux (Alcon)expels deeply from the meibomian glands the substances
responsible for their obstruction. The MAPRY protocol is based on one session per month at least

Astigmatism with TK more Accurate for Toric Calculation?This presentation explores the impact of Total Keratometry (TK) on the calculation of toric intraocular lenses (IOLs), focusing on the role of posterior corneal astigmatism (PCA) in refractive outcomes. Drawing on large datasets and recent studies, it highlights that PCA is a significant factor in toric IOL planning, with traditional keratometry often leading to over-correction of with-the-rule (WTR) and under-correction of against-the-rule (ATR) astigmatism. The presentation reviews evidence showing that using measured PCA values, rather than predicted ones, improves the accuracy of postoperative astigmatism prediction, especially when the steep axis of PCA is non-vertical. Comparative analysis of various toric IOL formulas demonstrates that EVO formulas with measured PCA yield the smallest centroid errors and highest percentage of eyes within 0.50D of predicted astigmatism, particularly in cases with non-vertical PCA. The findings underscore the importance of incorporating TK and measured PCA into toric IOL calculations to optimise refractive outcomes for cataract patients.

Simultaneous Vision IOLs ESCRS ClassificationThe rapid expansion of intraocular lens (IOL) designs and the increasing volume of clinical research supporting their functional outcomes have underscored the need for a unified and globally standardized Functional Vision Framework. The European, American, Asia-Pacific, and Latin American Societies of Cataract and Refractive Surgeons have collaboratively established the Global Functional Vision Working Group (FVWG) to harmonize terminology, methodologies, and outcome reporting in IOL evaluation. This initiative introduces a Functional Classification based on the depth of field (DOFi) and visual acuity enhancement across intermediate to near distances, organized into six progressive categories reflecting different visual performance profiles. Unlike regulatory classifications, such as ISO 11979-7:2024, which focus on safety and pre-market efficacy, the FVWG Functional Classification aims to provide post-market, clinically meaningful differentiation that aligns with patient-centered care and real-world functional benefits. The framework also advocates the integration of additional endpoints, including contrast sensitivity, biometric influences, and validated patient-reported outcome measures such as the AIOLIS questionnaire. Future directions emphasize the development of guidelines to assess the certainty of functional performance based on a hierarchy of evidence, from optical bench predictions to clinical validation and meta-analyses. By aligning technical and patient-oriented perspectives, the FVWG’s Functional Vision Framework represents a major advancement toward global standardization in IOL research and clinical practice. It provides clinicians, researchers, and industry with a robust foundation for consistent measurement, transparent communication, and improved shared decision-making in the selection and evaluation of IOL technologies.

Trends and Market Share of Presbyopia-Correcting Intraocular Lenses in Taiwan & Asia In this section, we will talk about the trends and market share of presbyopia-correcting intraocular lenses in Taiwan and Asia.Minimize Further Dehiscence of Zonules in Patients with Large Zonular Weakness Zonular weakness increases the likelihood of dealing with complicated cataract surgery and encountering postoperative complications. These risks include intra- and postoperative complications from cataract surgery, such as posterior capsular rupture, vitreous loss, and lens dislocation and decentration.
Common risk factors for weak zonules are pseudoexfoliation syndrome, mature cataracts, high myopia, Marfan syndrome, and prior ocular surgery. Signs of weak zonules include iridodonesis, phacodonesis, abnormal anterior chamber depth or asymmetry, angle asymmetry on gonioscopy, and vitreous in the anterior chamber. Zonular dehiscence and lens subluxation or dislocation can be seen in advanced zonulopathy. But most of the time, weak zonules may not be noticed until after the surgery has begun. Intraoperative signs of weak zonules include anterior chamber depth fluctuation, difficulty puncturing the anterior lens capsule, star-shaped striae on the capsule surface during the capsulorhexis, lens movement when manipulations, and difficulty in rotating the nucleus within the capsular bag despite adequate hydrodissection.
In this video discussion, we will talk about how to minimize further dehiscence of zonules in patients with large zonular weakness during operation and make the cataract surgery safer.

ESCRS Refractive Surgery GuidelinesThe ESCRS refractive surgery guidelines are evidence-based and provide fundamental classifications of ametropia, target refraction, and available refractive surgical procedures. For each procedure, the guidelines outline its variants, indications, advantages, and limitations. They also define safety thresholds and technical limits applicable to refractive surgery.
The guidelines describe the key components of the refractive surgery patient journey: (1) screening and patient selection, (2) diagnostic and preoperative evaluation, (3) procedure selection, (4) perioperative management, and (5) postoperative follow-up. Patient education and expectation management, including informed consent, are comprehensively addressed. Systemic and ocular contraindications, as well as dry eye disease and Meibomian gland dysfunction, are also discussed.
Common complications and side effects are listed, including both corneal and lens-related issues. The importance of surgeon experience is emphasized.
In summary, the refractive surgery guidelines serve as a clinical tool rather than a legal standard. They promote high-quality, well-informed patient care. Future updates will follow emerging evidence, with patient-reported outcome measures (PROMs) and personalized approaches representing key directions for development.

Safety Guidelines and Preoperative Assessment for Refractive Surgery: Challenges in High Myopia and Corneal Risk FactorsRefractive surgery has evolved substantially over the past decade, offering increasingly precise and predictable outcomes. Yet, ensuring patient safety—particularly in individuals with high myopia or underlying corneal risk factors—remains a core responsibility in clinical decision-making. This presentation provides an updated, evidence-based overview of safety guidelines and preoperative assessment strategies essential for optimizing refractive surgery outcomes.
We will begin by reviewing current standards for evaluating refractive stability, corneal biomechanics, epithelial thickness mapping, and posterior elevation indices. Special emphasis will be placed on the identification of subclinical keratoconus and forme-fruste ectasia, conditions that significantly elevate the risk of postoperative corneal ectasia. Practical screening algorithms—including integration of tomography, biomechanical testing, and individualized risk calculators—will be discussed to support accurate risk stratification.
High myopia presents unique challenges, including thinner corneas, greater ablation depth requirements, and a potentially higher susceptibility to biomechanical decompensation. The talk will highlight recent data on surgical candidacy thresholds, residual stromal bed safety margins, and considerations for choosing between LASIK, PRK, SMILE, or phakic IOL implantation in this population. Case-based examples will illustrate real-world pitfalls and decision-making nuances encountered in screening high-risk patients.
Finally, updated consensus recommendations and emerging technologies for improving preoperative detection and enhancing surgical safety will be summarized. By reinforcing rigorous assessment protocols and individualized risk evaluation, this presentation aims to support ophthalmologists in delivering safer, more predictable refractive surgery outcomes for patients with high myopia and complex corneal profiles.

ESCRS Cataract Guidelines RecommendationsThe ESCRS Cataract Guidelines represent a comprehensive and evidence-based framework designed to support cataract surgeons across Europe in delivering safe, effective, and consistent care. In this presentation, an overview of the most relevant recommendations will be provided as well as key updates based on the latest clinical evidence.
Drawing from robust literature reviews and expert consensus, the ESCRS Guidelines cover the full patient journey: from preoperative assessment and biometry, to surgical technique, IOL selection, intraoperative considerations, and postoperative care. Emphasis will be placed on areas of evolving practice (SV IOL and infection prophylaxis).
Background will be given on how the guideline development process was designed to ensure practical relevance while maintaining scientific rigor, and how implementation can be supported across diverse healthcare settings. The goal is not only to standardize best practices but also to allow flexibility where justified by patient needs or surgical complexity.
This talk aims to provide attendees with clear, actionable insights from the ESCRS Cataract Guidelines that can enhance surgical outcomes and support continuous quality improvement in cataract care.IOL Exchange in the Premium IOL Era: Challenges and SolutionsThe rise of simultaneous vision intraocular lenses (SV IOLs), including multifocal, extended depth of focus, and toric designs, has significantly expanded visual outcomes in cataract and refractive surgery. However, this progress has been accompanied by an increase in the complexity and frequency of postoperative patient dissatisfaction, leading to a higher demand for IOL exchange in select cases.
This presentation explores the unique challenges of IOL exchange in the era of SV IOL technologies. Key indications for explantation will be reviewed, including suboptimal visual quality, dysphotopsia, residual ametropia, and rotational instability. Emphasis will be placed on clinical decision-making, diagnostic precision, and the timing of intervention, particularly in light of evolving patient expectations. Surgical strategies for safe and effective explantation will be discussed.
In addition, the importance of careful patient selection, preoperative counseling, and enhanced biometric planning as critical factors in reducing the need for IOL exchange will be highlighted. Emerging technologies that may support more accurate IOL selection and customization will also be briefly introduced.
This talk aims to provide practical guidance for surgeons facing the growing demands of managing SV IOL complications and achieving optimal outcomes through safe exchange procedures.
