This study was conducted to check predominance of keratoconus in male and female of the various age groups in Pakistan and to check the severity of disease in keratoconus patients. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. A cross-sectional, analytical study was performed between September 2016 to May 2017 on Keratoconus patients visiting Layton Rahmatullah Benevolent Trust Hospital and Sir Ganga Ram Hospital during their ophthalmic consultation. The techniques used for the diagnosis of Keratoconus were Visual Acuity by Snellen chart, Ophthalmoscopy, Orbscan corneal topography, and Slit lamp bio microscopy. Total 110 patients of Keratoconus were studied in which 62 were females and 48 were males. Patients developed both unilateral as well as bilateral conditions. Visual acuity from normal to high vision loss was also observed in Keratoconus patients. Different disorders with different percentage such as Munson’s sign were present in 68 patients, Rizutti’s sign was present in 30 patients, Vogt’s striae were present in 26 patients and Fleischer ring was present in 23 patients. 19 patients had Atopic syndrome and 6 patients had Leber’s Congenital Amaurosis were also associated with keratoconus.
