The clinical arm of TIO is the Surgicentre.

The clinical arm of TIO is the Surgicentre. It’s a constant hub of activity with patients forming long lines for service from early morning.

From TIO’s inception, interventions and modalities such as modern cataract, corneal transplant, glaucoma, vitreo-retinal, orbital, strabismus and refractive surgeries have been offered.


A 24-hour emergency service department ensures those suffering from an eye injury or infection can receive treatment at any hour of the day or night.


The Surgicentre generates 100% of its running costs through patient fees. A cost recovery scheme utilises tier pricing and cross-subsidy where poorer patients receive indirect assistance from those who can afford to pay for treatment.

TIO believes that all patients should receive the same high quality care regardless of their means and background.

TIO’s Out-Patient Department (OPD) is where modern ophthalmic care is given to the general public. The Surgicentre manages on average about 600 patients each day.

Cornea and Refractive Surgical Services

In Nepal, corneal blindness is the second major cause of blindness after cataract. Corneal disease affects mainly young adults and people of a productive age, yet more than half of these cases are preventable. The corneal service at TIO is run by three dedicated cornea and anterior segment specialists.

Penetrating Keratoplasty (PKP) is a full thickness corneal transplant. It is the main corneal surgery performed at TIO. The most common indications of PKP are infective keratitis followed by corneal scars.

Lamellar Keratoplasty (LK) is a partial thickness transplant procedure that has gained popularity throughout the world and in TIO.

Deep Anterior Lamellar Keratoplasty (DALK) replaces the front of the cornea and is performed for selected patients with keratoconus, anterior stromal scars and stromal dystrophies. Graft rejection is less in DALK as compared to traditional corneal transplants, thus DALK is a very useful technique for countries like Nepal where patient follow up may be difficult.

Descemet Stripping Automated Eendothelial Keratoplasty (DSAEK) is another recently developed corneal lamellar surgery that is currently being performed at TIO. In this technique, no sutures are used and the shape of the natural outer cornea is not changed. As a result the visual outcome of DSAEK has been very good compared to penetrating keratoplasty. Since only the inner lining of the cornea is replaced the globe is a lot stronger in DSAEK as compared to PKP.

Keratoprosthesis: In this surgery the patient’s cornea is replaced by an artificial synthetic cornea. This surgery is indicated in cases where penetrating keratoplasty has a poor prognosis, such as repeated graft failure, chemical injury and limbal stem cell loss or severe corneal vascularization.

Other surgeries performed by the cornea service are scleral graft, Gunderson’s flap, limbal stem cell transplant (autograft or allograft), corneal glue, Pterygium surgery with conjunctival graft (shown to have a very small recurrence) and complicated cataract surgeries etc.

The corneal department also undertakes both the medical and surgical management of ocular surface tumours such as squamous cell carcinoma and malignant melanoma.

The most common corneal problems presenting in the subspeciality clinic are viral keratitis, microbial keratitis, corneal scars, keratoconjunctivitis and cases of post-operative corneal grafts.

Aside from the provision of quality patient care the cornea service is also engaged in training and research activities.

Our Services

From TIO’s inception to-date interventions and modalities such as modern cataract, corneal transplant, glaucoma surgeries, vitreo-retinal surgeries, orbital surgeries, strabismus surgery and refractive surgery have been offered.

General Services

An OPD (outpatient department) is where modern ophthalmic care is given to the general public.

Speciality Services

TIO’s clinical services are divided into a number of specialist services, each handling a particular sub-speciality of ophthalmology.

Laser Eye Surgery

Tilganga’s Refractive Surgery Unit opened in January 2012 and offers the latest in laser technology for the correction of corneal problems.

Eye Bank

The concept of the Eye Bank was supported by the International Federation of Eye and Tissue Banks (IFETB), before TIO was even built in 1994.
