Purpose: To understand the severity of keratoconus patients living in the central division of Fiji.

Methods: A total of sixty patients who attended to private clinic in Suva (Fiji) were reviewed. The severity of KCN was graded into three (3) groups from “Mild” (Group I, KCN <45 D), to “Moderate” (Group II, KCN45 to 52 D) and “Severe” (Group III, KCN >52 D). Refraction was determined by using objective and subjective criteria. Visual acuity was determined by using Snellen chart, converted into LogMAR scale. Corneal curvature was measured by using corneal topography. The severity of KCN is classified based on the CLEK study.

Results: A total of 55 patients with KCN were analysed, with a mean age of 25.01± 7.8 years. At the time of diagnosis, the severity of KCN was 36.3%, 43.6% and 20% in Groups I, II, and III, respectively. Mean BCVA with glasses was 0.22± 0.29 and with CL was 0.11±0.12 LogMAR. We found a statistically significant differences in the severity of KCN in those using spectacles compared to those using contact lenses in Group II (P£0.046) and a significant difference of visual outcomes in those using glasses compared to those using contact lenses is (P£0.009). 

Conclusion: Significant vision improvement was seen when prescribing contact lenses compared to spectacles. In Fiji, private practice optometrists should consider practising RGP contact lenses for better visual outcome in KCN patients.
