Neuroadaptation in Premium IOL PatientsNeuroadaptation is a key determinant of visual success and satisfaction after implantation of premium intraocular lenses. This session will discuss how the brain adapts to new optical conditions created by simultaneous vision IOLs, integrating multiple focal points while minimising photic phenomena. Clinical data and patient-reported outcomes will illustrate the variability and time course of adaptation, highlighting the influence of IOL design and individual neural plasticity. Understanding and supporting neuroadaptation are essential to optimise outcomes and enhance patient experience with modern premium IOL technologies.ESCRS Multiformulas IOL Power Calculator AccuracyAccurate intraocular lens (IOL) power calculation remains a critical determinant of refractive outcomes following cataract surgery. The ESCRS IOL Calculator integrates modern formulas to improve prediction accuracy and support IOL selection across diverse biometric profiles. This lecture will review recent data assessing the performance of the ESCRS Calculator in comparison with individual formulas, focusing on its refractive predictability, consistency across axial lengths, and clinical usability.
Results from validation studies and real-world datasets will be presented, highlighting the calculator’s strengths and limitations, as well as its role in optimising outcomes in standard and challenging eyes. The session will also address practical considerations for integration into clinical workflow and the ongoing evolution of formula combinations as biometry and lens technology continue to advance.

Intraoperative Aberrometry: Benefits or Distractions?Intraoperative Aberrometry (IA) is a microscope-mounted aberrometer that uses a laser wavefront analyzer to provide an intraoperative refractometer with live measurement. IA utilizes real-time wavefront analysis to measure IOL power in the aphakic state (after I&A but before IOL implantation), guiding Toric IOL axis alignment, and confirming final refraction in the pseudophakic stage (after IOL implantation). IA serves as an IOL power verification process by providing aphakic measurements.
IA has demonstrated improved accuracy compared to preoperative biometry and is most beneficial in complex cases, including post-refractive surgery eyes, eyes with uncertainty in preoperative biometry, and cases involving premium and toric IOL implantation, which results in less postoperative residual astigmatism.
IA accuracy is highly dependent on meeting specific intraoperative conditions. Erroneous measurements can occur due to factors like eyelid squeezing, speculum pressure, eye position/fixation, abnormal eye pressure, media conditions (OVD type and refractive index), corneal status, small pupil size, and IOL specifics. Caution is recommended when IA readings disagree significantly with preoperative measurements (e.g., a vector difference of 0.5 D in cases of low astigmatism).
Conclusion: Intraoperative Aberrometry is beneficial, especially for eyes with abnormal axial length, prior refractive surgery, toric IOLs, multifocal lenses, or uncertain biometry. IA functions as an additional measurement and verification tool. While IA can be beneficial when the surgeon masters the technique and all variables are optimized, it could be a distraction if optimization is not met.

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

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.

Two Eyes, One Day: The Evolving Landscape of Immediate Sequential Cataract SurgeryImmediate bilateral sequential lens-based surgery is increasingly adopted as a safe, effective, and patient-centred option for cataract and lens-based refractive procedures. This presentation reviews recent evidence on epidemiology, practice patterns, and outcomes across cataract surgery, refractive lens exchange, and phakic IOL implantation.
Studies demonstrate high efficacy in achieving refractive targets, rapid recovery of binocular vision, and consistent improvements in quality of life. Advances in biometry, surgical technology, and IOL design have further enhanced predictability and safety. Safety remains central, with very low rates of bilateral complications when established risk-reduction protocols—separate instrumentation, asepsis, and adherence to guidelines—are followed.
Comparisons with delayed sequential surgery show equivalent visual and refractive outcomes, along with reduced healthcare burden. This session will highlight current evidence on efficacy, safety, visual and refractive outcomes, and patient-reported benefits, while considering future directions in the expanding role of immediate bilateral sequential lens-based surgery.

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.

Intracorneal Implants in the Cataract Age: Expanding Vision Beyond LensesIntracorneal Implants in the Cataract Age: Expanding Vision Beyond Lenses
Introduction:
Intracorneal implants were developed as an additive, minimally invasive, and removable approach to address presbyopia and loss of accommodation. Designed to complement rather than replace existing ocular structures, they can be used in near-emmetropic eyes or combined with laser refractive procedures and monofocal intraocular lenses (IOLs) for pseudophakic patients. This study aimed to evaluate the long-term outcomes of combined cataract surgery and intracorneal microlens implantation

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.

Loose Zonules, Steady Hands: Saving the Unstable LensZonular dehiscence with vitreous prolapse represents one of the most challenging scenarios in cataract surgery. This case involves a 65-year-old female referred intraoperatively for severe temporal zonular dialysis extending 120° with vitreous prolapse into the anterior chamber.
In such situations, initial management options depend on the degree of capsular support and the surgeon’s familiarity with the anterior or posterior segment approaches. Possible options include: (1) primary pars plana lensectomy and vitrectomy (PPLV) with Yamane double-needle intrascleral fixation of an IOL; (2) anterior vitrectomy with in-the-bag or supplemental scleral fixation of a one-piece IOL using sutures; (3) pars plana vitreous levitation–assisted phacoemulsification; or (4) use of hooks or rings to preserve capsular support for in-the-bag implantation.
In this case, I stabilized the anterior capsule using iris retractors, performed a careful anterior vitrectomy, and completed a slow-motion phacoemulsification to minimize zonular stress. Following cortical cleanup, both an in-the-bag IOL and capsular tension ring (CTR) were successfully implanted. The patients visual acuity on postoperative day 1 was 0.9.
This surgical video illustrates a practical surgical maneuver with controlled movements, vitreous management, and structural stabilization techniques that allow safe phacoemulsification even in the setting of profound zonular loss.Pattern and Distribution of Uveitis Etiologies in Taiwan: A Multi-Center Perspective Uveitis is a heterogeneous group of intraocular inflammatory disorders with diverse etiologies and variable regional patterns. To delineate the current epidemiologic landscape of uveitis in Taiwan, a nationwide multicenter retrospective study was conducted collaboratively by the Taiwan Ocular Inflammation Society. Newly diagnosed uveitis cases from July 2022 to June 2023 were collected from 15 tertiary referral centers across northern, central, southern, and eastern Taiwan.
A total of 1,654 cases were analyzed. The mean age at onset was 49.5 ± 18.3 years, with nearly equal sex distribution (50.6% male). Anatomical classification includes anterior uveitis (64.3%), followed by panuveitis (22.4%), posterior uveitis (11.0%), and intermediate uveitis (2.3%). Etiologically, 43.6% were non-infectious, 23.5% infectious, and 32.9% undifferentiated. The leading non-infectious entities were HLA-B27/ankylosing spondylitis–related uveitis (15.4%), glaucomatocyclitic crisis (5.0%), and Vogt-Koyanagi-Harada syndrome (3.3%). Among infectious causes, herpetic anterior uveitis (7.7%), cytomegalovirus anterior uveitis (5.1%), and endogenous bacterial endophthalmitis (3.9%) predominated.
This large-scale multicenter study represents the most comprehensive epidemiological overview of uveitis in Taiwan to date. The unique disease pattern and relevant diagnostic challenges will be analyzed in this talk.

Blinded by White: Cracking the Mature Cataract Safely (Presentation and Discussion)This is an unusual white cataract with posterior synechiae and silicone oil in the vitreous cavity following previous retinal detachment surgery.Before starting the procedure, we noticed some emulsified silicone oil at the apex of the anterior chamber.I injected trypan blue through the side port to stain the anterior capsule, followed by OVD injection from the opposite angle to replace and remove the dye as well as the silicone oil.After using a flat needle to separate the posterior synechiae, four iris hooks were placed to enlarge the small, fixed pupil. Unfortunately, the initial staining was insufficient, so I performed a second capsule stain.At this point, wrinkles and fibrosis over the anterior capsule were noted, so I decided to use an MVR blade to create the initial cut for the CCC.The anterior capsule had thickened significantly, making it hard to tear. After several unsuccessful attempts to tear the anterior capsule with the CCC forceps, I switched to microscissors to complete the capsulorhexis as round as possible.Regrettably, it was not possible to complete the capsulorhexis on the opposite side, so I attempted to use the CCC forceps once more. Fortunately, I was finally able to complete the capsulorhexis, although it was quite small and irregular. Since the anterior capsule was quite thick, I was not concerned about causing a radial tear during hydrodissection.It was quite easy to rotate the nucleus afterwards.Since the nucleus was rock-hard, I attempted to use the stop-and-chop technique, initiated by a long and deep sculpting.If the sculpting is not deep enough, it will be difficult to crack and completely bisect the hard nucleus.Take your time and spread your phaco tip and second instrument along the trench, section by section.Afterwards, rotate the nucleus 90 degrees away. At the same time, the milkified cortex was floating outside the capsule.I buried the phaco tip as deep as possible into the center of the nucleus. This allowed me to hold the nucleus firmly and chop it vertically without detaching it from the phaco tip.After cracking the nucleus into smaller pieces, I was able to manage each piece within the central pupillary area safely and efficiently.It is important to separate the leathery tethering part of the posterior pole completely; otherwise, it will be difficult to keep the nucleus pieces under control. If you follow this principle and take your time, you will be able to complete emulsification safely and effectively within the limited space, with a CDE of only 18.77. Another surprise emerged after I cleaned the nucleus: I found a large central fibrotic plaque on the posterior capsule, with nearly no epinucleus or cortex remaining. Silicon oil was shiny behind the posterior capsule.In this situation, it’s impossible to perform primary posterior continuous curvilinear capsulorhexis (CCC); therefore, I decided to use a YAG laser to open the posterior capsule one month later.Following the injection of OVD into the capsular bag, an aspheric hydrophobic intraocular lens (IOL) was implanted smoothly.After removing the iris hooks, I used micro scissors to trim the redundant tags from the CCC margin.The entire procedure was completed with stroma hydration for the main wound and all side ports. We could notice the dense fibrotic plaque over the central axis during the slit lamp examination the day after surgery. However, the central visual axis could still become clear after YAG capsulotomy, and fundus photography could be taken beautifully.

Post-Op Red Flag: Beating Inflammation or Infection?Cataract surgery is one of the most frequently performed ophthalmic procedures and is generally associated with excellent visual outcomes. However, postoperative inflammation or infection can still lead to serious complications if not promptly recognized and managed. Distinguishing routine postoperative inflammation from sterile hyper-inflammatory reactions or early infectious endophthalmitis remains a clinical challenge. Importantly, reviewing the patient’s past medical and ocular history is essential, as underlying conditions such as uveitis, autoimmune disease, or prior ocular surgeries can significantly increase the risk and severity of postoperative inflammatory responses. Typical postoperative inflammation usually presents within the first few days and responds effectively to topical corticosteroids and nonsteroidal anti-inflammatory medications. In contrast, red flag signs—such as severe ocular pain, rapid vision decline, hypopyon, fibrin formation, or marked anterior chamber reaction—should raise suspicion for infectious endophthalmitis and prompt urgent intervention. Risk factors including wound leak, retained lens fragments, vitreous loss, or systemic immunosuppression further heighten concern. When media opacity limits direct examination, imaging tools such as anterior segment OCT and B-scan ultrasonography may assist diagnosis. Additionally, evidence supports tailored anti-inflammatory regimens perioperatively. Early recognition, patient education regarding warning symptoms, and timely referral to specialized care are critical in preventing irreversible visual loss. By identifying subtle clinical cues and considering patient-specific risk factors, ophthalmologists can effectively differentiate inflammation from infection and safeguard postoperative visual outcomes.

Pseudophakic Macular Edema: Stopping Vision Loss Before It StartsPseudophakic macular edema (Ervine-Gass syndrome) remains the most common cause of decreased visual acuity after uneventful cataract surgery. Previous study reported that 26.8% of eyes with pseudophakic macular edema did not recover 6/6 vision. Clinically significant pseudophakic macular edema impairing patients' vision is found in 1-2% of patients with its peak 6 weeks following surgery, but subclinical macular edema can be seen in about 30% of patients in FA and up to 40% in OCT. To date, there are no uniform recommendations for the treatment of pseudophakic macular edema. Therefore, I will present two cases of pseudophakic macular edema here and discuss the strategies for treatment.

Get the Things Right: Correction of IOL SubluxationDislocation of an intraocular lens (IOL) is an uncommon (0.2–3%) yet potentially serious complication, in which the IOL deviates from its normal anatomical position. It may arise from complicated cataract surgery, ocular trauma, previous vitreoretinal surgery, high myopia, or systemic or ocular conditions associated with zonular weakness. While mild cases may be observed initially, surgical intervention is usually required when significant visual symptoms occur. Various surgical techniques can be employed depending on the surgeon’s experience and the clinical scenario. In this presentation, I will demonstrate two approaches: the “twist-and-out” IOL removal and the “Yamane technique” for secondary IOL fixation. The advantages, limitations, and practical considerations of these techniques will also be discussed.

End the Bad Luck: Strategies for Refractive SurpriseDr. Chien will discuss the phenomenon of refraction surprise following cataract surgery—a postoperative outcome in which the patient’s refractive result differs from the intended target. Despite significant advancements in biometry technology, intraocular lens (IOL) power calculation formulas, and surgical techniques, refractive unpredictability can still occur and remains a noteworthy challenge in contemporary cataract surgery.
A variety of factors may contribute to refraction surprise, including inaccurate axial length measurement, corneal surface irregularities, posterior corneal astigmatism, unrecognized IOL tilt or decentration, and intraoperative issues such as capsular instability. Additionally, postoperative anatomical changes may further alter refractive outcomes.
Recognizing risk factors early and ensuring meticulous preoperative assessment are essential. When refraction surprise does occur, management options depend on both the underlying etiology and the magnitude of refractive deviation. Strategies include corneal refractive enhancement, piggyback IOL implantation, IOL exchange, or non-surgical approaches such as updating spectacles or contact lenses. Through case discussions and surgical experience sharing, Dr. Chien will present practical methods for preventing, diagnosing, and managing this complication—ultimately enhancing patient satisfaction and improving visual outcomes.
