99 FILM FESTIVAL (FF5) FILM FESTIVAL – IN-HOUSE PRODUCTION TITLE PRODUCER FF5-01 Contact Lens Shell Technique: A novel method for endothelial protection in high-risk cataract surgery Dinesh N MARU India This surgical video showcases a novel method for protecting the corneal endothelium during phacoemulsification in high-risk cataract cases, such as mature cataracts, cataracts with small pupils, shallow anterior chambers and hard cataracts. Traditional protective strategies may be insufficient in challenging scenarios, leading to endothelial cell loss and Pseudophakic Bullous Keratopathy (PBK). The Contact Lens Shell Technique (CLST) involves placing a thin, flexible disc made from a soft contact lens over the corneal endothelium during surgery. This shell acts as a barrier that deflects ultrasonic energy, dampens turbulent fluid currents, shields against mechanical trauma, and reduces overall endothelial stress. The CLST is presented as a simple, reproducible, and cost-effective addition to the surgeon's toolkit for high-risk cases. FF5-02 Levitate and Anchor: An alternative approach to scleral fixation for a dislocated CM-T flex lens with a fractured haptic Elizabeth Aileen GILLER Philippines This case involves a 65-year-old male who previously underwent secondary lens implantation with a CM-T Flex IOL, resulting in a fractured haptic that led to dislocation. The patient was referred for IOL explantation and secondary lens insertion. However, the case presented a unique challenge- the remaining haptic was stably fixated, and explantation risked inducing further trauma to the ocular structures. So instead, an alternative approach was made, involving levitation of the dislocated lens using a 25-gauge needle, trans-scleral fixation through the eyelet with a 6-0 Prolene suture, and flanging of the suture ends to ensure stable lens positioning. FF5-03 Beyond the Perfect Cut in Cataract Surgery: Navigating femtosecond laser complications Jessica CHOO Singapore The femtosecond laser has enabled surgeons to perform cataract surgery with higher precision. It is also a powerful tool in tackling difficult cataracts. However, no technology is immune to problems. This film highlights a series of femtosecond laser-related complications on various different laser systems, alongside practical pearls on how to prevent and address these setbacks. FF5-04 Demystifying the Barrett Toric Calculator: A scientific approach to IOL power calculation Narendrasingh VERMA India This video presentation explains the Barrett Toric Calculator in a simple, stepwise manner for ophthalmologists. The calculator is based on a thick-lens, vergence-based optical model using Gaussian optics and constructs a high-fidelity geometric eye model from five anatomical inputs: keratometry, AL, ACD, LT, and WTW. Using these parameters, it theoretically derives the ciliary plane, Lens Factor, principal planes of the IOL, and ELP, followed by iterative vergence calculations to refine IOL power. The formula addresses key sources of error through advanced strategies, like theoretical model for posterior corneal power, changes in IOL vergence related to lens Design Factor and power, conversion of classical axial length to segmental axial length equivalents It also improves spherical equivalent accuracy, making it reliable even for non-toric IOLs. FF5-05 Capture Conundrums – Optic stabilisation – when, where and how? Sushmitha SAMAK SRIGANESH India There are many situations where placing the IOL in the bag or sulcus may give rise to decentration or tilt. Optic capture can save the day and provide good stability by IOL fixation. We describe a series of cases with interesting situations where IOL stability was uncertain, and the techniques of optic capture used to manage it. These include optic capture, reverse optic capture and posterior capture through the posterior capsulorhexis. In this video we emphasis when to do it, where to do it and how to do it. FF5-06 Extraocularly Manipulated Transconjuctival Intrascleral Fixation of IOL Using Zigzag Needles Masayuki AKIMOTO Japan We have been being improving our techniques for intrascleral fixation of IOL that minimize intraocular manipulation and focus primarily on extraocular procedures. By employing a 27G needle bent in a zigzag pattern, we achieved flangeless transconjuctival intrascleral fixation of IOL based on extraocular manipulation.
