Abstract
Purpose
To compare conventional method of contact lens fitting with software based contact lens fitting using Medmont corneal topographer in eyes with nebular and macular corneal scars.
Methods
Fifteen participants who were diagnosed with nebular and macular scars were fitted with rigid gas permeable lenses using conventional method of contact lens fitting. During the lens dispensing visit, participants underwent Medmont corneal topography. Agreement between the two methods of contact lens fitting was studied.
Results
Parameters of contact lenses which were concluded using conventional method was compared to that of software based fitting. Mean difference in base curve of contact lens between the two methods was 0.094mm±0.147mm (95% CI: +0.383 to −0.194). Mean difference in diameter of contact lens between the two methods was 0.16mm±0.172mm (95% CI: +0.497 to −0.177). Contact lens parameters that were achieved using two different methods of fitting showed good correlation. Correlation coefficients, as comparison of two methods in base curve and diameter were 0.96 (P<0.05) and 0.94 (P<0.05), respectively.
Conclusion
Software based contact lens fitting would be useful for contact lens practitioners to predict initial base curve of contact lens in corneal scars.
