  1. Living With Keratoconus and Beyond, with Larry Kornhauser

    EPISODE 2

    Living With Keratoconus and Beyond, with Larry Kornhauser

    Guest: Larry Kornhauser, President of Keratoconus Australia In this episode, we flip the usual script and learn about keratoconus through lived experience. Our guest is Larry Kornhauser, co-founder and President of Keratoconus Australia and a tireless advocate for patients nationwide. Larry was diagnosed as a schoolkid in the 1960s, underwent a corneal transplant at 18, and has spent the past two decades helping others navigate a condition that can quietly upend education, work, and daily life. Larry takes us from classroom vision screenings and early hard-lens fittings to the joy of restored sight, the realities of cost and access, and why second opinions with an experienced fitter can be life-changing. We also unpack what keratoconus is—when the normally dome-shaped cornea thins and bulges into a cone, distorting vision. Larry shares practical advice for patients and families, reflects on the mental-health toll of uncertainty, and explains how advocacy, teaching clinics, and modern treatments like corneal cross-linking have transformed outcomes. In this episode: Larry’s diagnosis, transplant, and the bumpy road of early RGP lensesWhat keratoconus actually is, who it affects, and how it progressesCosts, funding hurdles (including NDIS realities), and where to find more affordable careThe power of a proper fit, backup spectacles, and seeking a second (or third) opinionCross-linking as a game-changer—and why avoiding eye rubbing mattersKeratoconus Australia and building a supportive community  This is a hopeful conversation. Larry’s story shows that with the right clinicians, the right lenses, and timely treatment, most people with keratoconus can study, work, travel, play sport—and simply get on with living. If you or someone you love has keratoconus, talk to an optometrist experienced in specialty contact lenses and ask about cross-linking assessment and teaching-clinic options in your state.

  2. Another Chance - on Corneal Surgery and Transplants, with Prof Mark Daniell

    EPISODE 3

    Another Chance - on Corneal Surgery and Transplants, with Prof Mark Daniell

    Guest: Professor Mark Daniell, Head of Corneal Research, Centre for Eye Research Australia In this episode, we unpack what a corneal transplant actually involves, why rejections happen, and how modern “layered” (lamellar) techniques like DSAEK/DMEK are changing recovery and outcomes. Mark also lifts the curtain on tissue-engineered corneas—how expanding a single donor could help treat more people worldwide—and a new hydrogel scaffold that aims to make delicate endothelial surgery faster, safer, and easier to perform in more places. In this episode: Why corneas fail: common reasons include keratoconus and endothelial failure (e.g., Fuchs dystrophy), where the inner cell layer can’t keep the cornea clear.From “open-sky” to layers: Full-thickness grafts (penetrating keratoplasty) once dominated, but today many patients get lamellar transplants—replacing only the diseased layer—improving vision quality and lowering rejection risk.Endothelial techniques:DSAEK/“DSEK” adds a thin stromal slice + endothelium.DMEK transplants just Descemet’s membrane + endothelium for the sharpest optics and the lowest rejection rates.Why rejections dropped: Fewer stromal immune cells (like dendritic cells) in lamellar grafts mean fewer immune alarms.Tech & tools matter: Microscopy, ultra-fine sutures, and air-bubble “sticking” steps are critical. Mini-scleral contact lenses also help post-graft vision.Global need: Millions need corneal surgery, but many regions lack eye banks and surgeons. Expanding endothelial cells from one donor into many grafts could be a game-changer.What’s next:A dissolving hydrogel scaffold that “pops open” like a tent to simplify DMEK-style surgery.Trials exploring cell-only injections of lab-grown endothelium.Longer-term efforts to bioprint stroma and generate cells from iPSCs (reprogrammed skin cells).

  5. Controlling Myopia at the Cornea with Dr. Nina Tahhan

    EPISODE 6

    Controlling Myopia at the Cornea with Dr. Nina Tahhan

    By 2050, half of the world’s population is expected to be myopic — and that comes with serious risks to lifelong vision. In this episode, host Lien Trinh speaks with Dr Nina Tahhan about how modern lifestyles are reshaping the way our eyes grow, why earlier onset is such a concern, and how cornea-based interventions such as soft myopia-control lenses and orthokeratology can slow progression and protect the next generation from irreversible vision loss. In this episode: The alarming rise of myopia worldwide and its impact on blindness and visual impairmentWhy central vision loss from myopic maculopathy is irreversibleEvidence-based prevention and the role of environmental and lifestyle factors — less time outdoors, more close workHow orthokeratology and specialised soft lenses reshape the cornea and retinal image profile to slow eye growthSafety of contact lenses in children — infection risks, hygiene, and follow-up carePractical advice for families: fitting, wearing time, and clinician partnership Key takeaways: Myopia is not just about glasses. It’s a structural condition that increases lifetime risk of retinal and macular disease.Outdoor time matters. Even a modest increase in outdoor play significantly reduces risk of myopia onset.Optical treatments work. Myopia-control contact lenses and orthokeratology have robust clinical evidence in slowing progression.Children can safely wear lenses when properly fitted and supervised.Regular reviews are essential — early detection and consistent follow-up protect long-term eye health.

    EPISODE 7

    Help! For Dry Eyes with A/Prof Holly Chinnery, Professor Laura Downie and Dr CeeCee Britten-Jones

    Episode guests A/Prof Holly Chinnery – University of Western Australia and Lions Eye Institute Corneal Immunology & Inflammation Research Fellow Professor Laura Downie – University of Melbourne Ocular Surface & Anterior Eye Clinician-Scientist Dr CeeCee Britten-Jones – University of Melbourne Senior Research Fellow Mona – dry eye sufferer Episode summary Dry eye is something almost everyone experiences. That gritty feeling, burning, tiredness after screens, or irritation from wind or air-conditioning. But when does it stop being a nuisance and become a disease? In this episode, Lien speaks with three leading Australian dry eye researchers to unpack: What dry eye disease really isWhy it affects people so differentlyThe two main subtypes of dry eyeWhat drives symptoms and inflammationCurrent treatments and new research directionsThe emotional and mental health impact of chronic dry eye We also hear from Mona, who shares her personal journey living with long-standing dry eye, and how it affected her daily life. Content note This episode includes discussions of mental health and suicide. Listener discretion is advised. Support services are listed below. Key takeaways Dry eye isn’t one disease, it’s an umbrella term for multiple types of tear film problemsHaving the right balance at the ocular surface requires a lot of coordination. Even small disruptions can lead to symptoms like burning, stinging, gritty sensation, blurred vision, and fluctuating comfort.Dry eyes can be inflammatory, and chronic. This explains why some people with mild signs experience severe symptoms, and why dry eye is linked with mental health impacts.Post-surgical dry eye is commonThere is data on Omega3 supplementation, but it is varied. Finding help: If you’re struggling with persistent dry eye, there are practitioners who specialise in dry eye diagnosis and management – from advanced imaging to tailored treatments including heat therapy, IPL, gland expression, and prescription options.

  7. Laser Eye Surgery - what you need to know with Ben LaHood

    EPISODE 8

    Laser Eye Surgery - what you need to know with Ben LaHood

    Guest: Dr Ben La Hood, specialist refractive surgeon and global education leader Episode Summary Laser vision correction is one of those topics people are fascinated by, but also a bit scared to take the next step on. In this season finale, Lien and Dr Ben La Hood break it down in plain language: what laser eye surgery actually means, how it reshapes the cornea, how modern procedures differ from older techniques, what the day feels like, who is and isn’t a good candidate, and what the real risks look like (including dry eye and rare complications like corneal ectasia). The goal is simple: help you feel clearer, calmer, and better informed if you’re considering the leap away from glasses or contact lenses. Key takeaways PRK, LASIK and SMILE all have pros/cons, and the “best” option depends on your eyes and lifestyle.The laser change is designed to be permanent, but your eyes still age (especially reading vision).Good screening matters: the safest outcomes come from the right candidates and conservative decision-making.Dry eye is real and should be discussed properly, but severe long-term dry eye is uncommon in appropriately selected patients.Your optometrist can help you choose a trustworthy referral pathway and interpret the pros/cons. Next steps for listeners Book a proper suitability assessment (including corneal mapping/topography and dry eye evaluation).If you have dry eye symptoms, consider treating the surface first, then reassess suitability.Bring your questions to your optometrist first — they see the long-term outcomes and can guide you to reputable refractive care.
