Corneal Disorders & Transplantation

The cornea is the eye’s clear, protective outer window and is the strongest lens of the eye. As a primary focusing element, its clarity and shape are vital for sharp vision. The clarity and shape can be affected from congenital diseases, genetic disorders or infections, inflammations and various degenerative conditions. When the cornea becomes scarred, swollen, or irregular due to any of the above factors, the impact on your sight and daily comfort can be profound.

Mr. Mrinal Rana is a Consultant Ophthalmic Surgeon specializing in the medical and surgical management of complex corneal conditions. His approach combines advanced diagnostic precision with a commitment to preserving your long-term ocular health.

Conditions Managed

Corneal diseases can affect various layers of the tissue and may stem from infection, genetics, or trauma. Mr. Rana provides expert care for a comprehensive range of conditions, including:

• Degenerative & Structural: Keratoconus, Other ectatic disorders, Terriens Degeneration.
• Inflammatory & Infectious: Infective Keratitis, inflammatory corneal ulcers, and neurotrophic conditions.
• Dystrophies & Swelling: Genetic disorders causing irregularity, deposition of products in the internal layers of cornea, Cellular death leading to progressive corneal functional failure.
• Surface Abnormalities: Pterygium, Pinguecula,recurrent corneal erosions and Salzmann nodular degeneration

When Is a Transplant Necessary?

If medical therapies, spectacles, specialized contact lenses, or minor procedures are no longer effective, a corneal transplant (keratoplasty) may be the definitive pathway to restoring your vision and relieving chronic discomfort.

The goal of transplantation is to replace diseased tissue with a clear donor cornea, tailored precisely to the layers of the eye that require treatment.

Modern Transplantation Techniques

In contemporary practice, we aim for "lamellar" surgery—replacing only the damaged layers while preserving as much of your healthy natural tissue as possible.

• DMEK & DSAEK (Endothelial Keratotomy): For conditions like Fuchs’ Dystrophy. We replace only the inner cell layer, resulting in rapid recovery and the lowest risk of rejection.
• DALK (Deep Anterior Lamellar Keratoplasty): Replaces the front and middle layers, keeping your healthy inner lining intact. This significantly enhances the long-term stability of the graft.
• PKP (Penetrating Keratoplasty): A traditional full-thickness transplant utilized for advanced scarring or severe structural irregularities.
• Patch Grafts: Specialized, smaller grafts used for urgent repairs or localized corneal perforations.

Understanding the Recovery & Risks

Corneal transplantation is a highly successful intervention. However, success depends on meticulous aftercare. While rejection is a primary concern, modern techniques particularly endothelial transplants have significantly reduced this risk.

Potential complications such as astigmatism, glaucoma, or graft failure are managed through a rigorous follow-up schedule. Early intervention is key: should you experience sudden redness, pain, or blurred vision, Mr. Rana provides the prompt specialist care needed to protect your graft.

Clinical Management: The Role of Steroids

Post-operative care is vital to prevent rejection.

• Topical Care: Steroid eye drops are essential to "calm" the immune system. The dosage is carefully tapered over time to balance graft safety with the prevention of side effects like raised eye pressure.
• Oral Medications: In specific high-risk cases, systemic (oral) steroids may be used temporarily. Mr. Rana monitors these closely to ensure your systemic health is prioritized alongside your vision.

A Specialist Standard of Care

As an NHS Lead in Corneal Services with advanced fellowship training, Mr. Mrinal Rana offers a level of expertise that bridges the gap between complex surgical research and compassionate patient care. Every treatment plan is discussed with honesty and transparency, ensuring you feel confident in the path chosen for your eyes.

Arrange a Specialist Assessment

If you are experiencing persistent light sensitivity, pain, or a decline in visual clarity, a specialist corneal evaluation is recommended. Early diagnosis is the most effective way to preserve your sight.
