Cornea makes this world beautiful to the person and it also makes person looks beautiful to the world. If it loses it texture and its transparency it become white, the person become blind and also makes him ugly to this world.
Cornea and ocular surface department at lotus eye hospital & Institute is dedicated to the management of cornea and ocular surface disorders. The department consist of well-trained corneal surgeons and is fully equipped with latest equipments and technology to provide state-of-the-art treatment and care for patients suffering from a wide variety of corneal disorders and infections. The department has an elaborate academic and surgical training programme for post-graduate students and general ophthalmology fellow.

Corneal dystrophies are inherited conditions where patients develop bilateral and symmetrical corneal opacities commonly involving the central cornea. This condition can cause a decrease in vision, as well as symptoms of irritation and watering.
Keratoconus is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve.
A ‘dry eye’ is a condition where patients suffer from irritation and discomfort in the eye because of the decreased quantity of tears or increased evaporation of tears from the eye.
Bacterial, viral, fungal and parasitic infections of the cornea may be sight threatening and at times, serious enough to cause loss of the eye. Timely diagnosis of the pathogen and appropriate treatment can help to save the eye and restore vision. Lotus Eye Hospital and Institute cornea department is supported by a microbiology laboratory for isolation of the organism.
Industrial and domestic use of chemicals is widespread. Many patients with acid and alkali injuries to the ocular surface are successfully treated at Lotus Eye Hospital and Institute hospital. Early and appropriate medical treatment followed by surgical interventions in the form of amniotic membrane grafts and autologous stem cell transplants are undertaken at Lotus Eye Hospital and Institute hospital.
Specular Microscopy: A Specular Microscope helps to document the health of the corneal endothelium and diagnose early cases of Fuchs endothelial dystrophy. The appropriate management of cataracts with compromised corneas is also helped by specular microscopy. Keeping a track of the endothelial cell count pre and post penetrating keratoplasty is made possible with clinical specular microscopy. Specular microscopy is also important before collagen cross linking and phakic intraocular lens implantation.
Photo slit-Lamp: Documentation of corneal pathology is aided by the Topcon slit lamp with digital camera unit and computer attachment. Tonopen: Intraocular pressure measurement in irregular, scarred, edematous corneas may be more accurately measured with this instrument. While applanation tonometry is still the gold standard for intraocular pressure measurement, tonopen provides a quick and reliable measurement in scarred, irregular corneas and in post penetrating keratoplasty where there may be variable corneal thickness and astigmatism.
Corneal Topography: Lotus eye hospital & Institute has Orbscan II which can evaluate the topography of the cornea as well as measure the corneal thickness. The orbscan has placido and slit scanning technology which can assist in detecting forme fruste keratoconus, post lasik ectasia, posterior keratoconus. Planned selective suture removal in penetrating and anterior lamellar keratoplasty is made easy with this technology. Aberrometry measures the optical aberrations of the eyeball.
Ultrasonic Biomicroscopy (UBM): UBM is an important tool in scarred and hazy corneas. Angle structures, crystalline lens, anterior or posterior chamber intraocular lenses can be visualized in cases where there is no visibility of the anterior segment.
Anterior segment OCT: It used to quantify the thickness of the cornea and to precisely locate the depth of corneal opacity and to see the integrity of descement’s membrane helps in lamellar keratoplasty.
The department offers most recent advances in the field of corneal surgery which include:
