Prevention of Argentinian flag sign in intumescent cataracts using anterior chamber air bubble and cortical fluid release techniques.

BACKGROUND: To investigate the efficiency of a new method for the prevention of argentinian flag sign during the process of continuous, circular, and centered anterior capsulotomy (CCC) on the anterior capsule in cortically liquefied intumescent cataracts. This study was registered in an appropriate registry and the registration number of registration was xyy11[2022]-XJSFX-087; The date of of registration was 2022-04-29. METHODS: Preoperative examinations including slit-lamp examination, ocular A-scan ultrasonography, and Ultrasound Biomicroscopy (UBM) UBM were conducted on 61 patients with intumescent cataracts. Cases with cortically liquefied intumescent cataracts were selected and after staining with indocyanine green, the anterior chamber air bubble technique was used to compress the anterior capsule, and liquefied cortex was aspirated using a puncture needle. Corrected Distance Visual Acuity (CDVA) and intraocular pressure were recorded on postoperative days 1, 1 week, 1 month, and 6 months. Intraoperative and postoperative complications were documented and analyzed. RESULTS: Fifty eyes were identified as having cortically liquefied intumescent cataracts. No cases of the Argentinian flag sign occurred, and standard capsulorrhexis was achieved, facilitating smooth phacoemulsification. All patients achieved satisfactory outcomes at follow-ups of 1 day, 1 week, 1 month, and 6 months postoperatively. Mild corneal edema was observed in three cases on the first postoperative day, with no other complications noted. CONCLUSIONS: The anterior chamber air bubble technique combined with cortical fluid release technique can prevent the occurrence of the Argentinian flag sign in cortically liquefied intumescent cataracts, this method is simple, convenient and economic for the clinical promotion.

"Inverted flap rhexis" - Salvation of intumescence.

Intumescent cataract can be a challenge even for an experienced surgeon, particularly for creating a continuous curvilinear capsulorhexis (CCC) because of increased endolenticular pressure. CCC in white intumescent cataract is associated with increased risk of extension of rhexis margin leading to radial tear or biradial extension causing "Argentinian flag sign" and associated complications. We describe a novel technique for CCC, in which we manipulate the vector forces acting in creating a capsulorhexis. After making a mini CCC, a flap is raised and then inverted under the rhexis margin and CCC is done by keeping the flap inverted using shearing and tearing forces, keeping the direction of force down and toward the center in a curvilinear fashion. It is a new surgical technique to perform a successful and safer CCC in intumescent cataract with consistent outcome.

Midperipheral mini-capsulorhexis as an additional step for safe phacoemulsification in white intumescent cataracts.

The present article describes a novel surgical technique of a primary mini-capsulorhexis in midperiphery to minimize surgical complications in white intumescent cataracts. Patients with white mature cataracts with a convex anterior capsule or swollen lens fibers were selected. An initial puncture was made 3-4 mm away from the center, in the midperipheral anterior capsule, with a conventional cystitome. A mini-capsulorhexis (2-2.5 mm) was created. Loose cortical matter and fluidic contents were aspirated to reduce the intralenticular pressure. Two cuts were made at the margin of the mini-capsulorhexis, and an adequately sized secondary rhexis was completed, after which phacoemulsification was done. A circular curvilinear capsulorhexis was successfully achieved in all cases, including those with a small pupil. Rhexis could be completed in a patient where an initial extension occurred due to head movement. This refined technique aims to enhance the safety and precision of capsulorhexis in intumescent cataracts, thereby reducing the risk of complications such as the Argentinian flag sign. Further exploration and validation of this approach through clinical trials are warranted to establish its efficacy and safety profile.

Preparing porcine lens to mimic human lens capsule.

PURPOSE: To develop a chemical method that makes porcine lens anterior capsule resemble human lens anterior capsule in tear force and perforating force. SETTING: Beijing Tongren Hospital, Beijing, China. DESIGN: Experimental study. METHODS: Porcine eyes were divided into groups, and reagents (0.9% physiological saline, 0.1% sodium hypochlorite, 0.3% sodium hypochlorite, and 0.5% sodium hypochlorite) were injected into the anterior chamber, respectively, recorded as Groups A, B, C, and D, respectively. A senior physician collected each group of anterior capsules after performing continuous circular capsulorhexis and assessing the anterior capsule's tearing and perforation forces. An additional group, which consisted of human lens anterior capsules taken in the operating room from patients with cataract, recorded as Group E. A tensile system was used to measure each sample's tensile force. RESULTS: A significant difference was found between Group A and any other group in maximum tensile force and average tensile force in both transverse and longitudinal directions. No significant difference was found between any 2 groups from Group B to Group E. According to the surgeon's assessment, the tear force characteristic of the porcine lens anterior capsule treated with 0.1%, 0.3%, and 0.5% sodium hypochlorite solution was similar to that of the human lens anterior capsule. CONCLUSIONS: Porcine lens capsule treated using this method can be used for training of new surgeons. The porcine lens anterior capsule treated with 0.5% sodium hypochlorite, which results showed most resembled human lens anterior capsule, can be used for robotic training.

Intraoperative trypan blue central landmark and its use in capsulotomy and capsulorhexis centration.

PURPOSE: To compare 3 capsulotomy centration methods. SETTING: Private clinic, Zlin, Czech Republic. DESIGN: Prospective, consecutive case series. METHODS: 180 eyes undergoing cataract surgery had anterior capsule staining with microfiltered 0.4% trypan blue solution before selective laser capsulotomy. The first 60 eyes (Group 1) had mydriatic dilated pupil centered capsulotomies. The next 60 eyes (Group 2) were centered on the trypan blue central landmark (TCL). The final 60 capsulotomies (Group 3) were centered on the patient fixated coaxial Purkinje reflex (CPR). Measurements between key anatomical landmarks and the TCL, CPR capsulotomies, and implanted intraocular lens (IOL) center were made. RESULTS: The TCL, observed in >94% of eyes in the study, coincided with the CPR with a displacement of <0.1 ± 0.1 mm. Group 1 capsulotomies were noticeably decentered on the IOLs by 0.3 ± 0.2 mm. The Group 2 symmetrical IOL relationship was maintained with a decentration of 0.15 ± 0.1 mm. Group 3 had a similar decentration with the IOLs with 0.15 ± 0.1 mm. Verification with IOLMaster 700 data and CALLISTO Eye System showed that the CPR and the TCL were coincident with the measured visual axis. CONCLUSIONS: The clearly visible TCL served as an alternate landmark to the patient fixated CPR, and being on the anterior capsule was not sensitive to tilt. Further patient compliance was not required. Both were superior to dilated pupil centration, to achieve symmetric IOL coverage. This has application for both capsulotomies and capsulorhexes.

A Modification of the Intraocular Lens Blocking Technique Without Posterior Capsulorhexis for Intraocular Foreign Body Removal.

PURPOSE: The intraocular lens blocking technique described for the removal of intraocular foreign bodies emerged as a result of an effort to prevent the foreign body from being retracted into the posterior segment because of the resistance encountered while removing it from the corneal incision. However, in the technique described, in addition to the difficulty of the surgical procedure, the new concern is to create a posterior capsulorhexis according to the size of the foreign body and to pass the foreign body through the capsulorhexis. METHODS: Here, the authors describe a new approach to the intraocular lens blocking technique. In this approach, the intraocular foreign body, which is held with intraocular forceps without any opening in the posterior capsule, is held in a perpendicular position to the long axis, lifted directly into the anterior chamber, and safely removed from the front of the monoblock foldable intraocular lens. RESULTS: In all patients treated with this approach, IOFBs were successfully removed without intraoperative or postoperative complications, and postoperative intraocular lens centralization was achieved in all patients. CONCLUSION: This approach may provide practicality to the intraocular lens blocking technique.

Impact of anterior capsule polishing on capsule opacification and capsule bend after age-related cataract surgery.

PURPOSE: To investigate the effect of anterior capsule polishing on postoperative capsule opacification and capsular bend in patients with age-related cataract displaying normal axial length. SETTING: Eye Hospital of Wenzhou Medical University at Hangzhou. DESIGN: Prospective self-controlled trial. METHODS: Patients with age-related cataracts aged 56 to 84 years displaying normal axial length were enrolled. Before surgery, a coin-toss method was used to randomly select 1 eye for intraoperative 360 degrees anterior capsule polishing (polishing group); the contralateral eye received no treatment (control group). Capsular bend index (CBI), anterior capsule opacification (ACO), posterior capsule opacification (PCO), and anterior capsule opening area (ACOA) were recorded at 1 week, 1 month, 3 months, 6 months, and 12 months postoperatively using swept-source optical coherence tomography and slitlamp examination. RESULTS: 21 patients (42 eyes) were enrolled. Within-group comparisons showed that both groups had significant differences in CBI between 1 week and 1 month postoperatively, and between 6 months and 12 months postoperatively ( P < .05). Between-group comparisons revealed a significant difference in CBI at 1 week postoperatively ( P < .05); at 12 months postoperatively, there was a significant difference in ACOA ( P < .05). There were no significant between-group differences regarding ACO or PCO at any timepoint ( P > .05). CONCLUSIONS: For patients with age-related cataracts and normal axial length, 360 degrees anterior capsule polishing can delay early capsular bag deformation without increasing the risks of ACO and PCO. This approach can also limit contraction of the anterior capsule opening.

ZEPTO-assisted pseudophakic capsulotomy: Precision pulse technology for management of capsular contraction syndrome.

We describe a novel technique that uses precision pulse capsulotomy (PPC) to perform a secondary capsulotomy for the management of anterior capsule contraction syndrome (ACCS), a condition that comprises a late complication after cataract surgery and intraocular lens (IOL) implantation. Micropulse secondary capsulotomy offers a controlled and safe approach for patients with severe anterior capsule contraction syndrome and may be considered as an alternative surgical technique.

Preventing the Argentinian flag sign and managing anterior capsular tears: A review.

The Argentinian flag sign (AFS) is a feared complication during cataract extraction. Intralenticular pressures, especially excessive posterior pressure, have been identified as potential mechanisms for capsular stress and tearing associated with AFS. Capsular tension is created by positive intralenticular pressures, which cause the irido-lens diaphragm to move anteriorly once the manual capsulorhexis has been initiated. This tension can cause inadvertent tears that self-propagate to the lens equator, causing an AFS, among other intraoperative complications. Thus, this review highlights the importance of identifying intumescent cataracts as well as a combination of techniques to relieve intracapsular pressures needed to prevent AFS. However, some instances of anterior capsular tears are unavoidable. Therefore, focus will also be placed on techniques during cataract extraction used to manage anterior capsular tears, mitigating extension to the posterior capsule.

Influence of posterior capsule abnormalities in pediatric cataract surgery.

PURPOSE: To report how to manage posterior capsule abnormalities (PCAs) in pediatric cataracts and evaluate the influence of PCAs during intraocular lens (IOL) optic implantation in Berger space surgeries. SETTING: Qingdao Eye Hospital of Shandong First Medical University, Qingdao, China. DESIGN: Retrospective case series study. METHODS: Pediatric patients with PCAs who underwent cataract surgery were evaluated. A video-based analysis of the surgical interventions included the type of crystalline lens opacification, types and management of PCAs, complications during primary posterior continuous curvilinear capsulorhexis (PCCC), need for anterior vitrectomy (AV), and feasibility of IOL optic capture. RESULTS: There were 227 pediatric cataract surgeries performed during the study period, and 76 eyes of 66 children with PCAs were evaluated (33.5%, 76/227). Unilateral cataract with PCAs were found in 50 eyes (22.0%, 50/227) and bilateral were found in 26 eyes (11.5%, 26/227). The PCAs were posterior capsule plaque (19.8%, 45/227), posterior capsule defect (6.2%, 14/227), posterior lenticonus (3.1%, 7/227), and persistent fetal vasculature (4.4%, 10/227). In the PCA cases, primary PCCC was successful in 44.7% of the cases (34/76). An unplanned AV during the surgeries was performed in 47.4% (36) of the 76 eyes. IOL optic implantation in Berger space was achieved in 63.2% of the eyes (48/76). CONCLUSIONS: PCAs are often encountered during pediatric cataract surgeries, especially in unilateral cases. The presence of PCAs may complicate a primary PCCC procedure, resulting in an unplanned AV in some cases. IOL optic implantation in Berger space can also be performed fortunately with well-designed and skilled operation.

Surgical challenges of posterior optic capture in pediatric cataract surgery.

PURPOSE: The efficacy of posterior optic capture (POC) in reducing posterior capsule opacification (PCO) in pediatric cataract is well recognized. The purpose of this paper was to identify the surgical challenges when attempting this technique and highlight the etiquettes to follow when performing this maneuver. METHODS: Prospective observational noncomparative case series. Children diagnosed with congenital or developmental cataracts undergoing cataract surgery and primary IOL implantation with posterior optic capture (and no anterior vitrectomy) from June 2017 to April 2022 at a tertiary care referral institute were included. Records of all intraoperative findings and postoperative complications until the last follow-up were noted. RESULTS: Posterior optic capture was attempted in 53 eyes of 49 children aged 2.4 ± 1.98 years. The mean follow-up of the patients was 16.5 ± 14.2 months (range 6 months-5 years). Successful POC could be performed in 46 eyes (86.8%). Two eyes developed posterior capsular opacification at the last follow-up. In eyes where POC could not be performed, five of these (83%) were children below 12 months of age with half of them having a preexisting posterior capsular defect. CONCLUSION: Posterior optic capture is technically challenging with a steep learning curve that can be mastered over time. Adequate relative sizing of the anterior and posterior capsulorhexis is important. Caution is advised when using this technique in infants and in cases with posterior capsular defects.

Flow capsulorhexis: A novel technique in white and hypermature cataracts.

We described a novel "flow capsulorhexis" technique in white and hypermature cataracts and compared it with the standard "needle decompression capsulorhexis" technique. Six hundred and eight eyes of 420 patients with intumescent or non-intumescent mature white cataracts who had undergone phacoemulsification or manual small incision cataract surgery with "flow capsulorhexis" (Group 1) or "needle decompression capsulorhexis" (Group 2) were assessed. The mean continuous curvilinear capsulorhexis (CCC) completion time was 6.6 ± 3.4 seconds in Group 1 and 10.4 ± 4.2 seconds in Group 2 (P < 0.001). The mean number of times for an ophthalmic viscosurgical device (OVD) supplement was 0.4 ± 0.2 and 1.8 ± 0.8 in Group 1 and Group 2, respectively (P < 0.001). CCC success rate was 95.8% in Group 1 and 87.2% in Group 2 (P = 0.001). The new technique was observed to have better outcomes in terms of surgical time, OVD supplement times, and success rate than the standard needle decompression technique.

[Shifts in the diameter of continuous circular capsulorhexis based on the Gullstrand eye model with the Callisto Eye System during cataract surgery].

Objective: To investigate the disparity between the set value of the capsulorhexis ring diameter in ophthalmic surgical navigation systems and the actual capsulorhexis ring diameter projected onto the lens surface. Methods: It was a cross-sectional study. Based on the Gullstrand eye model, the theoretical diameter of the capsulorhexis ring projected onto the lens plane through the cornea was calculated using the law of refraction in the Callisto Eye System. When the anterior chamber depth (ACD) ranged from 2.0 to 4.0 mm and the corneal curvature ranged from 40.00 to 48.00 D, the capsulorhexis ring diameters were calculated after projecting capsulorhexis rings with set diameters of 5.5 mm and 6.0 mm onto the lens plane. Additionally, 40 patients (40 eyes) aged 40 to 85 years who underwent cataract phacoemulsification combined with intraocular lens implantation at the Sixth People's Hospital of Shanghai Jiao Tong University School of Medicine were selected to validate the theoretical calculations. Among them, 15 were male, and 25 were female, and they were divided into three groups based on the ACD: group A (13 eyes) with ACD<3.0 mm; group B (16 eyes) with 3.0 mm≤ACD<3.5 mm; group C (11 eyes) with ACD≥3.5 mm. One week after surgery, anterior segment images of the eyes were taken, and the actual capsulorhexis ring diameter was measured using the Photoshop image processing software and compared with the set and calculated values. Results: When the capsulorhexis ring diameters were set at 5.5 mm and 6.0 mm and the corneal curvature was calculated based on the Gullstrand Eye model at 43.05 D, a linear negative correlation was found between ACD and the capsulorhexis ring diameter projected onto the lens plane (P<0.001). When the ACD was set at 2.5, 3.0, and 3.5 mm, and the capsulorhexis ring diameters were set at 5.5 and 6.0 mm, a linear negative correlation was observed between corneal curvature and the capsulorhexis ring diameter projected onto the lens plane (P<0.001). When the capsulorhexis ring diameter was set at 5.5 mm and the patient ACD and corneal curvature data were used for calculations, the capsulorhexis ring diameters projected onto the lens plane for groups A, B, and C were (5.09±0.05) mm, (4.97±0.05) mm, and (4.91±0.07) mm, respectively. When the capsulorhexis ring diameter was set at 6.0 mm, they were (5.56±0.05) mm, (5.44±0.05) mm, and (5.37±0.08) mm, respectively. One week after surgery, the actual measurements of capsulorhexis ring diameters for groups A, B, and C were (5.44±0.20) mm, (5.27±0.28) mm, and (5.25±0.41) mm, respectively, and the differences compared to the calculated values were not statistically significant (all P>0.05), but the differences compared to the set values were statistically significant (all P<0.001). Conclusion: The capsulorhexis ring diameter projected onto the lens surface by the Callisto Eye system was reduced by 7.33% to 10.48% compared to the set value, and the degree of reduction increased with the increase of ACD and corneal curvature.

CAPSULaser - a new modality in the portfolio of cataract surgeons.

To assess the efficiency and safety of capsulorhexis with CAPSULaser in comparison with standard capsulorhexis performed manually by emerging and established surgeons. Specialized Eye Hospital-Varna Bulgaria. Prospective, randomized, non-masked study. Patients were randomized to the M group (manual CCC), L group (laser CCC), and 2 surgeons. The manual CCC was targeted at 5.5 mm. The laser CCC was sized at 5.3 mm and measured with the same caliper device during photomicroscopy. The inclusion criteria were otherwise healthy eyes with cortical, nuclear, or subcapsular cataracts of any maturity with a biomicroscopically deep anterior chamber and preoperative pupil wider than 6.5 mm. The surgical time was measured for the entire procedure and only for capsulotomy. Sixty eyes of 60 patients, aged 65.8 ±â€…11 years, were prospectively recruited. Two surgeons (one with 3 years and one with 30 years of experience) performed the same types and number of procedures. The experienced surgeon was 2 times faster when performing manual capsulorhexis, but the time for CAPSULaser was almost the same. The size of the "laser" CCC was planned to be 5.3 and ended up with a minimum of 5.4 in 4 weeks; however, no lens prolapse from the CCC was observed. Utilization of the CAPSULaser in cataract surgery is easy and achievable for surgeons at any stage of their careers and provides controlled, well-centered capsulorhexis with no more adverse events than conventional surgery. The limitations are the requirement for a minimal pupil size of 6 mm, a deep anterior chamber, and a transparent cornea.

Dead bag syndrome-in the capsular bag subluxated intraocular lens centration and refixation: A new technique.

We describe a technique of scleral IOL fixation and optic centration of in the capsular bag subluxated IOL in a patient of "dead bag syndrome." A 29-year-old male diagnosed case of thalassemia presented with painless progressive diminution of vision in the left eye following uncomplicated sequential phacoemulsification in both eyes 15 years back. The right eye revealed completely centered IOL with significant amount of anterior capsular opacification (ACO), while the left eye revealed inferior subluxation of the IOL within capsular bag. The capsular bag was dilated, diaphanous with clear anterior and posterior capsule without any evidence of capsular fibrosis or opacification. Thus, a diagnosis of "dead bag syndrome" was made. The haptics were sutured to sclera (Hoffman's pockets) using two loops of 9-0 polypropylene, passed anterior and posterior to IOL haptics within the capsular bag. Postoperatively, the patient had a vision of 20/40 with a centered intraocular lens.

Postoperative intraocular lens stability following cataract surgery with or without primary posterior continuous curvilinear capsulorrhexis: an intra-individual randomized controlled trial.

PURPOSE: To evaluate the effect of primary posterior continuous curvilinear capsulorrhexis (PPCCC) on the positional stability of IOLs. METHODS: This study is a prospective intra-individual comparative randomized controlled trial including 31 patients (62 eyes). Eyes of the same patient were randomly assigned to the PPCCC group (18 right eyes and 13 left eyes) or group without PPCCC (NPCCC group). Eyes in both groups were implanted with a one-piece foldable hydrophobic acrylic IOL via routine cataract surgery. Patients in the PPCCC group underwent additional manual PPCCC before IOL implantation. Examinations were performed 1 day, 1 week, 1 month and 3 months postoperatively. IOL tilt (x, y), decentration (x, y), anterior chamber depth (z) and refractive prediction error data were collected and analyzed with Pentacam. RESULTS: Postoperatively, the range of IOL position change over 3 months in PPCCC group was comparable to NPCCC group, which indicated smaller value in every tilt and decentration index. PPCCC eyes showed comparable tilt and decentration with NPCCC eyes in this study endpoint: mean tilt (x, y), decentration (x, y) and anterior chamber depth (ACD) were 1.04 ± 0.56°, 0.90 ± 0.64°, 0.239 ± 0.140 mm, 0.233 ± 0.133 mm and 4.01 ± 0.32 mm, respectively, in the PPCCC group vs. 1.09 ± 0.76°, 1.10 ± 0.82°, 0.252 ± 0.153 mm, 0.244 ± 0.155 mm and 4.01 ± 0.38 mm, respectively, in the NPCCC group. Refractive prediction error in the PPCCC group demonstrated a mild hyperopic shift vs. the NPCCC group (0.13 ± 0.50 vs. 0.05 ± 0.39; p = 0.208), and corrected distance visual acuity (CDVA) did not differ between the two groups (0.027 ± 0.014 vs. 0.059 ± 0.185; p = 0.377). CONCLUSIONS: Comparable IOL tilt, decentration, ACD and refractive prediction error were observed in PPCCC eyes with that underwent routine cataract surgery. Little IOL position fluctuation and good visual acuity were shown in PPCCC group over time. TRAIL REGISTRATION: The study was registered at the Chinese Clinical Trial Register Center on May 27th, 2020 (protocol code ChiCTR2000033304, 27/05/2020).

Assessing the validity of flap motility sign in predicting the extent of anterior capsular tears in phacoemulsification.

Capsulorhexis is an integral step of cataract surgery, and continuous curvilinear capsulorhexis is crucial during phacoemulsification to prevent intraoperative complications. However, sometimes during phacoemulsification in complicated and hard cataract cases, rhexis extension may occur, resulting in posterior capsular rent, nucleus drop, cortex drop, and aphakia. It may not always be possible to continue with phacoemulsification in all cases. In this perspective, the authors describe a novel flap motility sign (FMS) to predict the extent of anterior capsular tear during phacoemulsification. A total of 21,678 patients underwent phacoemulsification for three years, from July 2016 to June 2019. One hundred and twenty-one patients had an anterior capsular tear. There were 102 cases (84.3%) with pre-equatorial tears and 19 cases (15.70%) with postequatorial tears. All pre-equatorial flaps were everted and fluttering, and all postequatorial flaps were inverted and nonfluttering. Posterior capsule rupture (PCR) was observed in all 19 cases of postequatorial flaps (100%). No PCR was observed in patients with fluttering and everted flaps (0%). In-the-bag and scleral-fixated intraocular lens implantations succeeded in pre-equatorial and postequatorial tears, respectively. There was no case of a nucleus drop. This study validates FMS as a predictor for identifying the extent of anterior capsular tears, thereby determining the endpoint of safe phacoemulsification and the site for intraocular lens implantation. Pre-equatorial tears allow for the continuation of safe phacoemulsification and in-the-bag intraocular implantation. Postequatorial tears necessitate timely conversion to small-incision cataract surgery or extracapsular cataract extraction.

Different strokes for anterior capsulorhexis in pediatric cataract.

Background: A successful outcome in pediatric cataract surgery is determined by an intact, curvilinear anterior capsulotomy which is dependent on the type and density of cataract, the morphology of the anterior capsule, and associated anterior segment pathologies. Purpose: This video highlights 10 different techniques which can be used for capsulorhexis in pediatric cataract. Synopsis: The choice of technique for capsulorhexis in pediatric cataract is on case basis, namely the gold standard manual capsulotomy aided by rhexis forceps (1. Standard capsulorhexis/2. Vitrector, Vitrectorhexis), with an assistance from capsular staining (3. Blue-rhexis), or by coaxial illumination (4. Coaxial-rhexis) or by just the sheen of capsule (5. Sheen-rhexis). The anterior chamber can be maintained using ophthalmic visco-elastic device (Visco-rhexis) or by irrigation fluid (6. Hydro-rhexis). A speed-breaker in the routine capsulotomy is the presence of plaque which is managed by rhexis forceps (7. Plaque-rhexis) or by a vitrector (vitrectorhexis) or a pair of micro-scissors (8. Scissor rhexis). Above all, the technology of femto-second-laser-assisted (9. Femto-rhexis) and zepto-pulse-precision capsulotomy (10. Zepto-rhexis) is also illustrated. Highlights: This video highlights the 10 different techniques of capsulorhexis in pediatric cataract surgery. Video Link: https://youtu.be/TgDrk5RYdbI.
