The Cornea Department at NIOH specializes in the diagnosis, medical management, and surgical treatment of corneal diseases, ocular surface disorders, and anterior segment conditions. With expertise in corneal transplantation, advanced imaging, and refractive procedures, the department plays a crucial role in restoring sight and preventing corneal blindness in Bangladesh.
Clinical Examination and Investigation
Comprehensive diagnostic facilities are available for
corneal and ocular surface disorders:
- Slit
Lamp Biomicroscopy – for detailed assessment of corneal pathology.
- Corneal
Topography / Tomography – for keratoconus, irregular astigmatism, and
pre-refractive evaluation.
- Specular
Microscopy – endothelial cell count and morphology assessment.
- Anterior
Segment Optical Coherence Tomography (AS-OCT).
- Pachymetry
(Ultrasound/Optical) – central corneal thickness measurement.
- Confocal
Microscopy – in vivo cellular level evaluation of corneal layers.
- Microbiological
Investigations – smear, culture, and sensitivity for infectious
keratitis.
- Tear
Film Assessment – Schirmer’s test, TBUT, and ocular surface staining
for dry eye evaluation.
Procedures
The department provides specialized procedures for diagnosis
and treatment:
- Corneal
Scraping & Culture – for infectious keratitis workup.
- Amniotic
Membrane Transplantation (AMT) – for ocular surface reconstruction.
- Collagen
Cross-Linking (CXL) – for keratoconus and ectatic corneal disorders.
- Bandage
Contact Lens Fitting – for painful corneal conditions and epithelial
defects.
- Tissue
Adhesive & Bandage Contact Lens – for corneal perforations.
- Pterygium
Excision with Conjunctival Autograft.
- Limbal
Stem Cell Transplantation (Autologous/Allogenic).
- Tear
Film Procedures – punctal plugs, cautery for dry eye management.
- Contact
Lens Evaluation & Fitting – in severe corneal blindness cases.
Surgical Services
The department performs advanced corneal and anterior
segment surgeries:
- Therapeutic
Keratoplasty – for uncontrolled infectious keratitis or corneal
perforations.
- Optical
Keratoplasty – to restore vision in corneal opacity.
- Refractive
Surgeries (LASIK, PRK, ICL) – correction of myopia, hyperopia, and
astigmatism.
- Corneal
Repair Surgeries – for trauma, lacerations, and perforations.
- Ocular
Surface Reconstruction – in chemical burns and severe ocular surface
disease.
- Combined
Corneal & Cataract Surgeries – “Triple procedure” (PKP + IOL +
cataract extraction).
- Collagen
Cross Linking- For corneal ectatic disorders like keratoconus
Cornea Services – Treatment Plans & Strategies
The Cornea Department at NIOH ensures specialized care
and prevention of corneal blindness through:
- Eye
Banking & Corneal Transplantation: Active collaboration with
national and international eye banks to ensure tissue availability.
- Early
Diagnosis & Medical Management: Prompt treatment of corneal
ulcers, keratitis, and dry eye disorders.
- Refractive
Services: Providing safe, effective refractive surgery for visual
rehabilitation.
- Community
Outreach: Screening for corneal diseases and promoting awareness about
eye donation.
- Training
& Research: Educating ophthalmology residents and fellows in
corneal surgery and ocular surface management.
- Advocacy
with policy making: For ensuring availability of corneal graft and
easy access to services including surgery.
