    Therapeutic Keratoplasty : A Comprehensive Review

    Microbial keratitis is a common vision-threatening disease that occurs in all parts of the world and is an important cause of avoidable corneal blindness. Medical therapy is considered a mainstay in the management of microbial keratitis, however, cases that worsen despite medical therapy or have perforation require surgical management1. Therapeutic keratoplasty is a surgical procedure whose primary purpose is to get rid of the infectious or non-infectious inflammatory tissue along with the restoration of the structural integrity of the eye (tectonic support)2. The surgical procedure, postoperative course, and chances of graft survival in therapeutic keratoplasty are different from optical keratoplasty as surgery is performed on an inflamed eye. Therapeutic keratoplasty could be Therapeutic Penetrating Keratoplasty(ThPK) Therapeutic lamellar keratoplasty- Deep Anterior Lamellar Keratoplasty(Th-DALK) Patch graft In therapeutic penetrating keratoplasty, a full-thickness button of the dise

    Instruments used in Corneal Procedures and Surgeries

    Although tales and myths of ocular surgery and organ transplantation appear in numerous ancient texts, the earliest accounts of ophthalmic diseases were written as a treatise by Sushruta, in the 6th century BC. Sushruta described 76 eye diseases, out of which 51 required surgical treatment. In the western world, the concepts of corneal surgery date back to Greek physician Galen (130-200AD). The concepts to improve corneal clarity by surgery were developed over the next centuries and especially in the 17th and 18th centuries. But the major scientific progress and experimentation in the field of corneal surgeries happened in the 19th century. The progress in corneal surgery was hindered by a lack of understanding of immunology, asepsis, surgical procedures, and of course, the lack of proper instrumentation. Emmert Wolf wrote over a century ago, “A man is only as good as his tools.” Early surgeons were hampered by a lack of proper surgical instruments. Over the centuries, innumerable opht

    Ocular Surface Squamous Neoplasia

    A. Introduction There have been multiple refinements in the terminology of the epithelial squamous neoplasia until the introduction of the term “Ocular surface squamous neoplasia” (OSSN) by Lee and Hirst in 19951. OSSN is an umbrella term and refers to a spectrum ranging from mild/moderate/severe dysplasia to carcinoma in situ to invasive squamous cell carcinoma involving the conjunctiva and/or cornea2-4. OSSN is the most common tumor of the ocular surface. According to the epidemiological studies, the worldwide incidence of OSSN is 0.02 to 3.5 cases per 100,000 people. Incidence increases with decreasing latitude, being higher in countries located close to the equator. OSSN predominantly occurs in the elderly age group (6th to 7th decade) and in male gender 5-9. B. Etiology and pathogenesis10-27 The presumptive risk factors implicated in the etiology of OSSN include: Excessive exposure to ultraviolet radiation Heavy cigarette smoking Immunosuppressive conditions: Human Immunodeficienc
