👁 What is CCC (Continuous Curvilinear Capsulorrhexis)?Introduced by Gimbel and Neuhann in 1984A key step in cataract surgeryCreates a smooth circular opening (5–5.5 mm) in the anterior lens capsulePrevents radial tears during phaco or IOL insertion🌀 What is the Argentina Flag Sign?A rapid bilateral radial tear of the anterior capsuleNamed for its resemblance to the Argentinian flagOften occurs..

👁 What is CCC in Cataract Surgery?Modern cataract surgery primarily involvesphacoemulsification followed by posterior chamber intraocular lens (IOL) implantation.A critical step in this process isCCC (Continuous Curvilinear Capsulorrhexis).🧬 What is CCC?A smooth, round opening (~5–5.5 mm) is created in the anterior lens capsuleAllows safe access for phacoemulsification and IOL insertionEssenti..

👁 What is Steroid-Induced Glaucoma (SIG)?Steroid-induced glaucoma (SIG) is a form of secondary glaucomacaused by elevated intraocular pressure (IOP) after using steroids,whether topical, periocular, systemic, or injected.🔬 Mechanism of SIGSteroids alter trabecular meshwork structure↑ ECM (extracellular matrix) deposition↓ Phagocytic activity → waste builds up→ Outflow resistance increases → IO..

👁 What is Toxic Cataract?A toxic cataract refers to a lens opacity induced by medications or chemical substances,used either topically (e.g., eye drops) or systemically (oral or injectable drugs). 🔬 Common Cataract-Inducing DrugsDrug TypeAgentCataract TypeSteroidsPrednisolonePosterior subcapsular (PSC)AntipsychoticsChlorpromazineAnterior subcapsular + corneal depositsAnticancerBusulfanPosteri..

👁 Ocular Anatomy: Anterior vs Posterior SegmentThe human eye is structurally divided into two major parts:Anterior Segment and Posterior Segment,separated by the posterior lens capsule / anterior vitreous face.🔹 Anterior SegmentStructures:CorneaIrisCiliary bodyLensChambers:In front of the iris: Anterior chamberBehind the iris: Posterior chamberFluid:Aqueous humorFlow: Produced by ciliary body ..

👁 Modern Cataract Surgery: Phacoemulsification & IOL InsertionThe current standard method for cataract surgery isphacoemulsification followed by posterior chamber intraocular lens (IOL) implantation.Though femtosecond laser is occasionally used, ultrasound remains central to cataract removal. 🧬 Key Surgical Steps (Simplified)Corneal IncisionCreates an entry point for surgical toolsCCC (Contin..

👁 Cataract Surgery & Lens Anatomy ExplainedModern cataract surgery typically uses phacoemulsification with intraocular lens (IOL) implantation,a method first introduced by Kelman in 1967.📌 Surgical Goal EvolutionTransitioned from restoring cloudy vision to achieving→ better refractive outcomes→ fewer surgical complicationsBut complications like posterior capsule rupture, iris prolapse, radial ..

👁 Cataracts: Causes and Antioxidant Eye DropsCataracts remain the leading cause of blindness worldwide,accounting for nearly 48% of all blindness cases.While surgery is well-established, pharmacological prevention or delay is still under-researched.🔍 Key Risk FactorsAging, diabetes, UV exposure, malnutrition, smoking, renal diseaseMost importantly: Oxidative Stress→ Free radicals damage lens p..

👁 What is Central Corneal Thickness (CCT)?CCT refers to the thickness of the central cornea,playing a critical role in refractive surgery screening and intraocular pressure (IOP) correction in glaucoma patients.🔍 Clinical Importance of CCTRefractive Surgery PlanningDetermines suitability and surgical safetyOverestimated CCT → Risk of overcorrection or ectasiaUnderestimated CCT → Patient wrongl..
