  • 盧兆功 Chao-Kung LuTaiwan Speaker 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.
  • 簡湘文 Hsiang-Wen ChianTaiwan Speaker Stop and Chop: Bridging Classic Sculpting with Modern ChoppingStop and Chop remains a cornerstone phacoemulsification technique that elegantly bridges the precision of classic sculpting with the efficiency of modern chopping. This 10-minute lecture demonstrates a streamlined, low-energy approach to nucleus management, emphasizing initial central sculpting to create a secure mechanical barrier, followed by controlled cracking and targeted chopping to minimize ultrasound energy and endothelial stress. Key steps include optimized trench depth, chopper positioning for safe lens rotation, and sequential quadrant emulsification with fluidic balance.
  • 莊智鈞 Chih-Chun ChuangTaiwan Speaker 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.

  • Panel Discussion
    Pannet PangputhipongThailand Speaker 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.
    Matteo PiovellaItaly Speaker 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 for 5 months, depending the grade and penetration ofhronic eyelids inflammation
    FAM Han BorSingapore Speaker 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.

  • Joaquín FERNÁNDEZSpain Speaker 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.
  • 賴俊杰 Chun-Chieh LaiTaiwan Speaker 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.

  • Pavel STODULKA Speaker 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.
  • 侯鈞賀 Chiun-Ho HouTaiwan Speaker 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.

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.
  • 許粹剛 Tsui-Kang HsuTaiwan Speaker When the Capsule Gives Way: Winning the Posterior Rupture BattleCataract surgery is the most commonly performed operation in ophthalmology and despite tremendous instrumental and technological advancements, posterior capsular rupture (PCR) still occurs. PCR occurs both in all eye surgeons, although with a higher frequency in the newer starter group. Additionally, certain types of cataracts are prone to this development. If handled properly in a timely method, the eventual outcome may be no different from that of an uncomplicated case. However, improper management may lead to serious complications with a higher incidence of permanent visual impairment. The speech disclose the management of PCR from two perspectives: 1. Identifying patients with higher risk and know the sign of early PCR, and measures to manage such patients by surgical maneuver, and 2. Intraoperative management of posterior capsular rupture with anterior vitrectomy with different setting and various case scenarios to prevent further long-term complications. Solution for Residual Large Lens Material with PCRCompromise of the posterior capsule can occur in the hands of both new and experienced surgeons. Learning how to prevent, avoid, or efficiently manage posterior capsular rupture (PCR) is important. If PCR is present with residual lens material and vitreous loss, it is important to disentangle the vitreous from any nuclear/cortical fragments to ensure their safe removal without creating vitreous traction in case of retinal detachment. The vitreous can be stained by using preservative-free triamcinolone to delineate its presence in the anterior chamber and any incarceration in the wound. Anterior vitrectomy can be performed to remove the vitreous from the anterior segment properly. Alternatively, suppose the surgeon is comfortable with a pars plana approach which is better route. In that senario, a pars plana vitrectomy can be done, which helps to pull the vitreous back to the posterior segment, and avoids excessive anterior chamber manipulation. The pars plana approach may also permit better access to residual lens material—the vitrector may be used to clear nuclear and cortical material with a change in settings. At the end of the case, the wounds should be checked carefully to ensure no vitreous is present. A suture or more if necessary, depending on wound size, should be placed at the primary wound. Pupillary miosis should be done to inspect the pupil. If the pupil is peaked, there is likely vitreous still present in the anterior chamber and possibly in the wound. Once the vitreous is adequately cleared, one may carefully resume phacoemulsification and insert an IOL in various methods.
  • 黃宇軒 Yu-Hsuan HuangTaiwan Speaker Managing Large Posterior Capsular Rupture with Residual Cortex in Toric or Premium IOL CasesManaging a large posterior capsular rupture (PCR) during cataract surgery is particularly challenging when a one-piece toric or premium IOL is planned. This case demonstrates that, when partial posterior capsular support remains, in-the-bag implantation of a single-piece premium IOL is still feasible with careful assessment and technique. A large central PCR occurred unexpectedly after nucleus removal. Early recognition, immediate stabilization of the anterior chamber with viscoelastic, lowering IOP, and preventing tear extension were essential steps. Residual cortex was safely removed using dry aspiration with a Simcoe cannula combined with gentle polishing, allowing complete cleanup without further damage. Although alternative IOL options were unavailable, the rupture did not align with the astigmatic axis, and sufficient capsule remained to support a toric IOL. The IOL was placed in the bag, and reverse optic capture (ROC) was performed to enhance long-term stability. ROC preserved the effective lens position by capturing the optic anterior to the capsulorhexis while keeping the haptics in the bag. Postoperatively, the IOL remained well-centered with favorable refractive outcomes. This case shows that large PCR does not necessarily preclude premium IOL use when managed with proper surgical strategy, including ROC.
  • FAM Han BorSingapore Speaker 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.
  • Gerd U. AuffarthGermany Speaker Unhappy Patient with Two Different Diffractive IOLs.Title: Unhappy Patient with Two Different Diffractive IOLs Author: Gerd U. Auffarth This is a case report about a 76-year-old patient who attended my clinic in 2008. He underwent cataract surgery on his right eye and an IQ Restor SN6AD1 was implanted. The second eye was not operated on for almost nine years, and then, in 2017, the patient underwent cataract surgery on the left eye. Interestingly, a different surgeon performed the surgery and said that the original intraocular lens (IOL) was no longer available, so a Tecnis Symfony ZXR00 was implanted instead. The patient was not satisfied with the outcome. He complained of blurred vision, could not read road signs while driving, and had different colour perception in both eyes. He noticed that the image in his right eye with the blue filter lens appeared more brown than the image in his left eye, and he could not get used to this over the years. In daily life, this was very bothersome for him. The patient complained that the doctors tried several corrective lenses and PCO laser was performed on the right eye. All without any positive effect on this vision. The results of the visual acuity examination were: uncorrected 20/30 in both eyes and 20/25 binocularly for distance. For near vision, it was 20/40 in both eyes and 20/30 binocularly. His refraction was +0.5, -0.25 @ 130° in the right eye and +0.25, -0.5 @ 77° in the left eye. The patient was not satisfied with the visual outcome and the different optics, as the AcrySof IQ Restor is a multifocal IOL with a 3.0 near addition and a blue light filter, whereas the Tecnis Symfony has an extended depth of focus design and no blue light filter. The surgical options were IOL explantation of one or both lenses and reimplantation of either a monofocal or another multifocal intraocular lens. However, the previous laser capsulotomy on the right eye could be problematic for this. In addition, the patient did not want any extensive surgery. The aim was to help him by achieving good binocular visual performance, with particular focus on visual quality and balanced performance. Visual acuity was not really something that could be addressed. In the end, the patient received a special pinhole add-on lens (Morcher Extrafocus). This is a pinhole optic with a central opening of 1.3 mm, which was placed in the right eye. This reduced the amount of light entering the eye and consequently diminished colour perception, which made the visual impression more similar to that of the left eye. One week after the surgery, the patient was extremely satisfied, especially because he could see and read in balance. Visual acuity remained at 20/30, similar to before. However, after two months, his visual acuity had improved on both sides between 20/25 and 20/20, and it was 20/20 for distance and near vision as well. He is now a very satisfied patient as he wouldn't say there is a big difference between his right and left eyes, he doesn't need glasses anymore, and his quality of life has improved.

  • 曾垂鍊 Chui-Lien TsenTaiwan Speaker Operating on the Edge: Surviving Cataract Surgery in Post-AACG Zonular Disaster This video demonstrates the surgical management of a mature cataract in an eye with a history of acute angle-closure glaucoma (AACG) complicated by zonular dialysis. The procedure highlights key steps for anterior chamber stabilization, controlled capsulorhexis under shallow conditions, and safe nucleus removal using phaco techniques. Intraoperative support with capsular tension ring and viscoelastic-assisted chamber maintenance was critical to preserving capsular integrity. Despite severe zonular weakness, careful pacing and early mechanical stabilization allowed successful in-the-bag intraocular lens implantation with minimal intraoperative complications. Postoperative recovery was stable with good visual outcome. Cataract surgery after AACG with zonular compromise remains one of the most technically demanding situations in anterior segment surgery. This case illustrates that with meticulous fluidic control, supportive devices, and adaptive strategy, even a “zonular disaster” can end with a safe and satisfying surgical result.
