Cornea and Keratoconus

Cornea is the transparent front-most part of the eye through which light enters the eye.  At Mahajan Eye Centre (MEC) we offer full range of corneal diagnostic and therapeutic services and expertise of reputed cornea specialists for management of various corneal ailments especially keratoconus and corneal transplantation. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape.

Corneal Topography and Other Diagnostic Investigations

At MEC, we offer the latest corneal imaging modalities: Pentacam (Scheimpflug imaging system-Oculus, Germany) and Atlas (Placido topography system-Humphrey, USA) for in-depth study of corneal surface shape to diagnose and monitor progression of even the earliest cases of keratoconus and other corneal diseases. Pentacam is special as it gives detailed analysis of the back surface of cornea as well which is usually not available with traditional topography tests. We also have ultrasonic pachymetry (Sonomed, USA) for corneal thickness measurement and anterior segment OCT (Optical Coherence Tomography) (Zeiss, Germany) for detailed corneal study.

Corneal Collagen Crosslinking (CXL/ C3R)

At MEC, we also offer CXL or C3R. It is a relatively new form of therapy for keratoconus patients, which aims at arresting the progression of keratoconus by strengthening the corneal architecture. It involves treating the cornea with high concentrations of vitamin B (Riboflavin) followed by exposure to UV light. The treatment induces cross linkage of corneal collagen fibers at the molecular level. It also aids in better contact lens fitting in these patients and reduces the need for major surgeries like corneal transplantation.

Intra-corneal Ring Segments (Intacs/ KeraRings)

Eyes with keratoconus often have cylindrical errors that cannot be completely corrected with glasses. Thus, large semi-soft gas-permeable lenses are the mainstay of treatment for eyes with keratoconus. These will be required even after C3R treatment (because C3R only helps to prevent the further progression of keratoconus). However, in patients with advanced keratoconus, the considerable cylindrical error may not allow even a contact lens fitting.

To reduce these large cylindrical errors seen in keratoconus, specially designed plastic ring segments may be surgically implanted in the cornea, to significantly reduce the cylindrical error enabling good contact lens fit and improve the quality of vision.



Corneal Transplantation

Advanced cases of keratoconus and many other corneal ailments may require corneal transplantation. It is a surgical procedure where a damaged or diseased cornea is replaced by the donated corneal tissue (the graft) in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty). MEC is an authorized corneal transplantation centre (GNCT Delhi). MEC also offers latest automated lamellar corneal transplantation for DSAEK or ALTK using advanced corneal microkeratome system form Gebauer, Germany.
