FILM FESTIVAL 80 Film Festival FF3 – Refractive/Corneal Surgery Title Producer FF3-01 Novel Technique of Concomitant Endoscopyassisted Total Pars Plana Vitrectomy in Boston Keratoprosthesis Type 1 Dominique GEOFFRION Canada Posterior segment complications after Boston keratoprosthesis type 1 (Boston KPro) lead to severe visual loss but can be decreased with total pars plana vitrectomy (PPV) performed at the time of Boston KPro implantation. However, anterior hyaloid peeling during PPV is challenging. This video will demonstrate that endoscopy during 23-gauge PPV at the time of Boston KPro implantation, with no temporary KPro, allows a rare view of retroiridal structures and facilitates anterior hyaloid peeling, which is otherwise technically challenging. This novel technique, reported here for the first time, may shorten operative time, allow for rare intraocular assessment, and reduce glaucoma progression and retinal detachment incidence. FF3-02 Advanced Ophthalmic Radiofrequency Technology: Conjunctivochalasis, electrolysis & punctal occlusion Chul Young CHOI South Korea Using high-frequency radiowave technology, various ophthalmic diseases were treated including conjunctivochlasis, chronic chemosis, electrolysis for trichiasis, and punctal occlusion in aqueous deficiency dry eye disease. Ophthalmic radiofrequency (RF) electric unit (Acutron TM, 2Mhz 0.4~0.8 Watt, frequency, Ilooda, Seoul, Korea) and micron thickness electrode (1~2 micron thickness in tip part, OcuRF) were used for the treatment for 12 months by the same surgeon (C.Y. Choi) and reviewed retrospectively. Ophthalmic Micro-RF treatment using ultrathin electrode in various ophthalmic diseases might be a simple and safe surgical option without complications. FF3-03 Scleral Uncrosslinking: A minimally invasive presbyopia solution Robert ANG Philippines Aging brings about a stiffening of the sclera, decreasing the ciliary muscle’s ability to zoom the lens and participate in accommodation. Laser scleral microporation (LSM) is a new presbyopic procedure that uses an erbium YAG laser to create a matrix of micropores in four quadrants of the sclera in each eye. LSM uncrosslinks the myofibrils, thereby decreasing scleral biomechanical stiffness, increasing ciliary muscle forces and increasing lens shape changes during accommodation. Monocular uncorrected near vision improved from 0.43 logMar to 0.20 logMar. Residual accommodation improved from 0.47 D to 1.35 D. LSM is a promising procedure that improves intermediate and near vision without touching the visual axis and compromising distance vision. FF3-04 Intraoperative OCT – The third eye, connection to the unknown realm Jai KELKAR India Diagnostic OCT acts like a third eye, helping us to see beyond the visible. It has revolutionized the way we look at the internal structures of the eye. Optical coherence tomography, by employing near infrared light, penetrates into the ocular media to obtain high resolution images of the intraocular structures. Intraoperative optical coherence tomography (iOCT) is a noninvasive imaging modality that provides a real-time dynamic feedback of the various surgical steps. Combining this technology intraoperatively to the operating microscope has been phenomenal. With the help of this video, we would like to demonstrate the use of this third eye in various challenging corneal surgeries. FF3-05 Intraoperative Optical Coherence Tomography Guided Management of Post-LASIK Epithelial Ingrowth Jeewan TITIYAL India We present a spectrum of cases with epithelial ingrowth, with management ranging from observation alone to intraoperative OCT (iOCT) guided removal of epithelial ingrowth to flap amputation. An iOCT guided removal of epithelial ingrowth was performed in one case with post-LASIK epithelial ingrowth. Real-time visualization of interface guided on-table decision-making regarding extent of lifting the flap to encompass entire hyperreflective epithelial ingrowth, as well as need for additional interventions to ensure complete flap apposition at end of surgery. The second case with long-standing flap dislocation and coexisting epithelial ingrowth encroaching the pupillary area was managed with flap amputation and removal of epithelial ingrowth. Optimal visual outcomes were achieved in all cases.
