Keratoconus is an abnormal bulging of the anterior surface of cornea due to thinning and progressive degeneration. The shape of cornea changes and leads to lot of distortion of visual images and fluctuating vision. It usually affects both eyes, although one eye may be affected more than the other. Patients usually complain of lot of glare and decreased vision.

As it is a progressive disorder, its early diagnosis and treatment is necessary. Keratoconus is most often diagnosed in Individuals in the age group of 10-40 years.

Family history of keratoconus Vigorous rubbing of the eyes Presence of allergic condition like asthma, hay fever or presence of disorders like Downs syndrome, Retinitis pigmentosa etc.

DIAGNOSIS

Examination – Slit lamp examination is crucial to assess the status of cornea. Early cases can be missed on slit lamp examination, although advanced cases show the typical cone type structure of cornea. IMAGING & CORNEAL MAPPING– Corneal topography and corneal tomography shows the contour and thickness of cornea and is instrumental in diagnosing keratoconus. Get your examination done today if you are experiencing any of the symptoms.

TREATMENT –

GLASSES - The doctor prescribes glasses after correction of refractive error as they are helpful in initial stages of mild keratoconus.

CONTACT LENSES – Rigid contact lenses or scleral lenses are prescribed in initial stages of keratoconus. These lenses allow oxygen to pass through the contact lens and help reshape cornea to minimize vision distortion.

COLLAGEN CROSSLINKING (CXL) – Collagen cross linking is a minimally invasive procedure that helps to increase the binding in the collagen layer and helps to prevent keratoconus from progressing further. The surgeon puts riboflavin eye drops on the cornea and then exposes the cornea surface to ultraviolet light to induce the crosslinking of collagen fibers and increase their strength.

SURGERY- Patients with keratoconus have higher order aberrations due to which they are not happy as the visual quality is severely compromised. These cases are advised to undergo surgery when no other option is available. PINHOLE PUPILLOPLASTY (PPP) – Dr. Priya Narang and her team have done detailed research on pinhole pupilloplasty procedure that can be applied for cases with severe keratoconus that have higher order aberrations. Pinhole acuity is achieved in these cases and patients are highly satisfied.
