Cornea
Brief History
The department is well equipped with instrumentation and technology to provide state-of-the-art care for
patients suffering from a wide variety of corneal disorders. The department has an elaborate academic and
surgical training programme for doctors & staff in cornea and external eye diseases.
Clinical Services
The department caters to the efficient diagnosis and management of a wide range of diseases.
Congential and hereditary corneal disorders
Corneal and scleral infections
Ectatic corneal disorders – Keratoconus, Terriens marginal degeneration, Pellucid Marginal degeneration
Immunologic disorders of cornea
Peripheral ulcerative keratitis
Ocular surface disorders including severe dry eye, blepharitis, ocular allergies, chemical injuries, Stevens Johnson syndrome and ocular surface tumors
Investigations and Diagnostic Services
Corneal Topography (Scirrus) - Evaluates shape and power of the corneal surface. The Pentacam, based
on the Schiempflug photography is unique in that it provides invaluable information that other
instruments are incapable of measuring.
Confocal Microscopy : Live microscopic imaging of corneal disorders
Pachymetry : Measurement of corneal thickness using ultrasound
Aberrometry : ( I-Trace Aberrometer, Allegro Analyser) Measures the optical aberrations of the eye
Specular Microscopy Study of the corneal endothelium (cells that maintain corneal clarity)
Anterior – Segment OCT : (Optovue)Helps identify depth of corneal scarring/lesions on the cornea, corneal thickness, anterior chamber details
Tear Osmolarity : Measures tear osmolarity helping detect dry eye
Anterior segment digital photography : Photographic documentation of various corneal conditions for baseline documentation, and monitoring effects of therapy as well as to monitor progression of the disease in any ectatic disorder.
Customized laser refractive surgery : A strategy to correct not only the refractive error but also the other optical imperfections of the eye, by surface ablation (Supralasik), Lasik and PTK by schwind Eyetech Solution.
Collagen cross linking for Keratoconus : Procedure performed to stabilize the disease.
Surgeries
The department offers most recent advances in the field of corneal surgery which include
Penetrating Keratoplasty (PK) : Optical, tectonic and therapeutic with anterior segment
reconstruction, combined with SFIOL, Vitreo-retinal procedures and Paediatric PK.
Lamellar corneal surgeries : Including Automated Lamellar Therapeutic Keratoplasty (ALTK),
Deep Anterior Lamellar Keratoplasty (DALK), Deep Lamellar Endothelial Keratoplasty (DLEK) and
Descemet's Stripping EndoKeratoplasty (DSEK), Descemet’s Membrane Endothelial Keratoplasty (DMEK)
Pterygium surgery : Conjunctival Autograft, amniotic membrane graf(Conjunctival mobilazation)
Management of wide range of ocular surface tumor including surgery and chemotheraphy
Comprehensive management of SJS/ chemical injuries /ocular allergies/ ocular surface disorders
The Ocular Surface Clinic : one of the first of its kind in the country, caters to a wide
variety of surface disorders including dry eye, ocular allergies, chemical injuries and Stevens
Johnson syndrome. Started in 2005, the clinic offers comprehensive care and makes available the
entire spectrum of treatment modalities for ocular surface disorders under one roof.
It is the only centre in the world which performs all kinds of keratoprosthesis (artificial cornea)
surgeries. 230 Keratoprosthesis surgeries have been performed so far.
Other surgeries performed include :
- Ocular surface reconstruction
- Amniotic membrane transplantation
- Recurrent Pterygium surgeries
- Limbal autografts and allografts
- Mucous membrane grafting
Artificial cornea (Keratoprosthesis) :
- Boston Type 1 keratoprosthesis and its variants
- Modified Osteo-Odonto Keratoprosthesis
- Pintucci Keratoprosthesis
- Boston Type 2/Lucia Type 2 Keratoprosthesis
- Tibial keratoprosthesis
