Purpose: To describe the characteristics of keratoconus (KC) patients seen in a contact lens clinic of a children's hospital in Kenya. Methods: This was a retrospective study of patient's records with KC. Data collected included gender, age at presentation, source of referral, main complaint at referral, severity of KC, best-corrected visual acuity (BCVA), and management before the presentation and following assessment. Results: A total of 254 patients' records were analyzed. Mean age at presentation to the clinic was 20.97 ± 11.13 year (range, 6-84 years) with 75% between the ages of 6 and 25 years. There was a preponderance of males (59.8%). Most patients were referred by an ophthalmologist. All patients were Africans. The most common complaints were blurred vision (50%), poor visual acuity with spectacles (33.5%), contact lens intolerance (11.8%), and other (unspecified). Most cases were severe (71%) followed by moderate (22.9%) and mild (6.2%). Mean BCVA was 0.24 ± 0.23 (6/11). An optical correction was provided in 98% of cases; 34.6% with spectacles, 31.1% with gas permeable lenses and the remaining with both. Referral for keratoplasty was warranted in 16.5%. Conclusion: This is the first study of KC conducted in Kenya. KC presented at a very early age and tended to be severe. Ophthalmologists were the main source of referral. The main presenting symptom was reduced vision. Optical correction was the most common management and the percentage of patients referred for surgery concurred with other studies.
