Purpose: To determine demographic characteristic feature of keratoconus, degree of keratoconus which impairment the visual acuity and to explore patient who lives in hot climate suffer from keratoconus symptoms. Methods: This study include 210 patients which diagnosed keratoconus, is liable for our hospital’s patient population among 2015 to 2018. Routine ophthalmological examination was performed and autokeratorefractive error, best spectacle corrected visual acuity (BSCVA), demographic features was determined. At the end of the study number of applications and complaint to hospital were considered. Results: 81.4% patients were in the range of 20-30 years. Except 15 patients all of them were male. There were unilateral keratoconus in 66 patients. BSCVA was 4/10 and below with Snellen lines in 21.75% eye; Spherical equivalent was 3 Dioptre and below in 216 eye (61.01%). Keratometric measures were determined 44.00 Dioptre till in 120 eye (33.89%). Purely, 64 patient were performed cross-linking, corneal ring etc. Conclusion: Keratoconus is a degenerative corneal disorder which is occured more often in young men as it is in our study. Bilateral involvement is frequently determined. BSCVA is 8/10 and below in 68.85%. Spherical equivalent 3.00 Dioptre and below eye is 59.01%, that’s why ophthalmologists are alert of early diagnosis of keratoconus. We observed that these patients suffered from subjective complaint constantly because of hot climate of the region we live in.
