Abstract

Aim: To compare the contrast sensitivity test with different modes of refractive correction in myopes with low astigmatism.

Objectives: To compare different modes of refractive correction to achieve better contrast sensitivity in myopes with low astigmatism.

• Best corrected spherical equivalent lens in trial frame
• SCL
• RGP

To measure CS with Pelli-Robson CS chart and mobile application CS chart (Smart Optometry) with different modes of refractive correction.

Methods: In a prospective clinical trial comprised on 36 eyes of 22 subjects were enrolledbased on inclusion and exclusion criteria. Subjects were corrected by three different modes: 1). Best-corrected SE in trial frame 2)SCL 3)RGP. All the subjects were corrected with BCVA of 0.0 LogMAR and Spherical Equivalent(SE) was calculated. Contrast sensitivity were measured using Pelli-Robson chart and mobile application (Smart Optometry).

Results: Soft contact lens have given better contrast sensitivity as compared to SE in spectacle trial frame and RGP in both Pelli-robson chart and mobile application (Smart Optometry). While by measuring with PR chart and mobile application chart, mobile application gave the good contrast sensitivity. And no significant difference was found between dominant and non-dominant eyes in the patient whom we have included two eyes for the study.

Conclusion: Soft contact lens was better option when compared with RGP and BCVA trial lens as alternative to toric prescription in myopes with low astigmatism.
